C6665/ C FORM - 2 THE PATENTS ACT, 1970 (39 of 1970) & The Patents Rules, 2003 COMPLETE SPECIFICATION (See Section 10 and Rule 13) SOFTENING LAUNDRY DETERGENT HINDUSTAN LEVER LIMITED, a company incorporated under , the Indian Companies Act, 1913 and having its registered office at Hindustan Lever House, 165/166, Backbay Reclamation, Mumbai -400 020, Maharashtra, India The following specification particularly describes the invention and the manner in which it is to be performed. WO 2005/054419 PCT/EP2004/013161 - 1 – -SOFTENING LAUNDRY DETERGENT- FIELD OF THE INVENTION 5 This invention relates to laundry conditioning compositions. More particularly, the invention is directed to conditioning liquid laundry compositions with improved particulate soil cleaning. 10 BACKGROUND OF THE INVENTION Traditionally, textile fabrics, including clothes, have been cleaned with laundry detergents, which provide excellent soil removal," but can often make garments feel harsh after 15 washing. To combat this problem, a number of fabric conditioning technologies, including rinse-added softeners, dryer sheets, and 2-in-1 detergent softeners, have been developed. 2-in-1 detergent softeners have normally been the most convenient of these technologies for consumers, but 20 many of these existing technologies still have disadvantages. One of the more effective technologies for this type of product, systems comprising cationic polymers, softens quite well but can contribute to soil deposition, hindering the cleaning performance of the detergent. 25 Anionic soil release and antiredeposition polymers are often used to improve cleaning, but normally, the amount of certain types of anionic polymers added to a fabric conditioning system including cationic polymers is 30 minimized. It is believed, without wishing to be bound by WO 2005/054419 PCT/EP2004/013161 - 2 - theory, that anionic polymers can complex with the cationic polymers and have a detrimental effect on softening. Softening laundry detergent compositions have been disclosed 5 in published U.S. Patent Nos. 6,616,705; 6,620,209; and 4,844,821. Washer added fabric softening compositions have been disclosed in U.S. Patent Nos. 4,913,828 and 5,073,274. 10 Fabric softener compositions have been disclosed in WO 00/70005 and U.S. Patent No. 6,492,322. Lazare-Laporte, et al., European Patent No. EP 0 786 517 discloses a detergent composition including (a) surfactant 15 material, (b) amphiphilic carboxy containing polymer, and (c) uncharged polymer. A process for producing suspending liquid laundry detergents has been disclosed in Hsu, U.S. Patent No. 6,369,018. Hsu discloses the use of cationic cellulose ether (polymer JR ) in an anionic surfactant 20 containing liquid detergent and further requires a polysaccharide polymer such as xanthan gum. As optional, Hsu et al. describe soil release polymers in encapsulated form. 25 A need remains for softening laundry detergent compositions including cationic polymers for improved softening achieved through adding the compositions in the wash cycle of automatic washing machines, while avoiding soil redeposition. Surprisingly, we have found that certain 30 anionic polymers are compatible with cationic fabric conditioning polymers, allowing the formulation of products WO.2005/054419 PCT/EP2004/013161 - 3 - that give excellent softening without compromising cleaning performance. SUMMARY; OF THE INVENTION 5 A conditioning liquid laundry composition with improved particulate soil cleaning comprising: a. at least 5 % of at least one anionic surfactant; 10 b. 0.01 % to 5% of at least one amphiphilic carboxy containing polymer, preferably, an anionic polyacrylate; c. 0.05 % to 3 % of polyvinylpyrrolidone polymer (an uncharged polymer); and 15 d. at least one cationic conditioning polymer. Preferably, the inventive laundry composition has a Softening Parameter of greater than 40, a delta E of less than 12, and one or more of the cationic polymers has a 20 molecular weight of less than 850,000 daltons. More preferably, the inventive composition has a Softening Parameter of greater than 70; most preferably, the Softening Parameter is greater than 80, for maximum softening at the same cleaning capacity. 25 In another aspect, this invention is directed to a method for conditioning textiles comprising, in no particular order, the steps of: 30 a. providing a laundry detergent or fabric softener composition comprising at least one WO 2005/054419 PCT/EP2004/013161 - 4 - anionic surfactant and at least one cationic polymer, in a ratio and concentration to effectively soften and condition fabrics under predetermined laundering conditions; 5 b. contacting one or more articles with the composition at one or more points during a laundering process; and 10 c. allowing the articles to dry or mechanically tumble-drying them. Preferably, the amphiphilic carboxy containing polymer is an anionic polyacrylate polymer. 15 Cationic polymers include dimethyl diallyl ammonium chloride/acrylamide copolymer, dimethyl diallyl ammonium chloride/acrylic acid/acrylamide terpolymer, vinylpyrrolidone/methyl vinyl imidazolium chloride 20 copolymer, polydimethyl diallyl ammonium chloride, starch hydroxypropyl trimmonium chloride, polymethacryl amidopropyl trimethyl ammonium chloride, acrylamidopropyl trimmonium chloride/acrylamide copolymer, guar hydroxypropyl trimonium chloride, hydroxyethyl cellulose derivatized with trimethyl 25 ammonium substituted epoxide, and mixtures thereof. WO 2005/054419 PCT/EP2004/013161 - 5 - DETAILED DESCRIPTION OF THE INVENTION The present invention is directed to conditioning liquid laundry compositions which deliver both effective softening 5 and effective particulate soil cleaning, including: (a) at least 5 % of one or more anionic surfactant; (b) 0.01 % to 5% of at least one amphiphilic carboxy containing polymer, preferably an anionic polyacrylate; 10 (c) 0.05 % to 3 % of polyvinylpyrrolidone (an uncharged polymer); and (d) one or more cationic polymers that deliver a high level of conditioning to fabrics. 15 The present invention is based on the surprising finding that certain cationic polymer and anionic surfactant mixtures provide excellent conditioning to laundered fabrics, while effectively preventing redeposition with inclusion of anionic polymer/polyvinylpyrrolidone anti- 20 redeposition system. Preferably, the anionic polymer is an amphiphilic carboxy containing polymer. In a preferred embodiment, the compositions of the present invention yield softening parameters of greater than 70, a 25 delta E of less than 12, and one or more of the cationic polymers has a molecular weight of less than 850,000 daltons. More preferably, the inventive composition has a delta E of less than 7 and a Softening Parameter of greater than 80, for maximum softening at a given cleaning capacity. 30 WO 2005/054419 PCT/EP2004/013161 - 6 - As used herein, the term "comprising" means including, made up of, composed of, consisting and/or consisting essentially of. As used herein, the term "substantially free of precipitation" 5 means that insoluble and substantially insoluble matter will be limited to less than 10% of the composition, more preferably tO 5% or less. Except in the operating and comparative examples, or where 10 otherwise explicitly indicated, all numbers in this description indicating amounts or ratios of material or conditions of reaction, physical properties of materials and/or use are to be understood as modified by the word "". 15 ANIONIC SURFACTANT In order to attain the desired level of softening, with a Softening Parameter of greater than 70, the inventive softening laundry compositions contain greater than 5% 20 anionic surfactant by weight of the composition. The anionic surfactants used in this invention can be any anionic surfactant that is water soluble. "Water soluble" surfactants are, unless otherwise noted, here defined to 25 include surfactants which are soluble or dispersible to at least the extent of 0.01% by weight in distilled water at 25°C. "Anionic surfactants" are defined herein as amphiphilic molecules with an average molecular weight of less than 10,000, comprising one or more functional groups 30 that exhibit a net anionic charge when in aqueous solution at the normal wash pH of between 6 and 11. It is preferred WO 2005/054419 PCT/EP2004/013161 - 7 - that at least one or the anionic surfactants used in this invention be an alkali or alkaline earth metal salt of a natural or synthetic fatty acid containing between 4 and 30 carbon atoms. It is especially preferred to use a mixture 5 of carboxylic acid salts with one or more other anionic surfactants. Another important class of anionic compounds are the water soluble salts, particularly the alkali metal salts, .of organic sulfur reaction products having in their molecular structure an alkyl radical containing from 6 to 24 10 carbon atoms and a radical selected from the group consisting of sulfonic and sulfuric acid ester radicals. Carboxylic Acid Salts 15 R1COOM where R1 is a primary or secondary alkyl group of 4 to 30 carbon atoms and M is a solubilizing cation. The alkyl group represented by R1 may represent a mixture of chain 20 lengths and may be saturated or unsaturated, although it is preferred that at least two thirds of the R1 groups have a chain length of between 8 and 18 carbon atoms. Nonlimiting examples of suitable alkyl group sources include the fatty acids derived from coconut oil, tallow, tall oil and palm 25 kernel oil. For the purposes of minimizing odor, however, it is often desirable to use primarily saturated carboxylic acids. Such materials are available from many commercial sources, such as Uniqema (Wilmington, Del.) and Twin Rivers Technologies (Quincy, Mass.). The solubilizing cation, M, 30 may be any cation that confers water solubility to the product, although monovalent moieties are generally preferred. Examples of acceptable solubilizing cations for WO 2005/054419 PCT/EP2004/013161 - 8 - use with this invention include alkali metals such as sodium and potassium, which are particularly preferred, and amines such as triethanolammonium, ammonium and morpholinium. Although, when used, the majority of the fatty acid should 5 be incorporated into the formulation in neutralized salt form, it is often preferable to leave a small amount of free fatty acid in the formulation, as this can aid in the maintenance of product viscosity 10 Primary Alkyl Sulfates R20SO3M where R2 is a primary alkyl group of 8 to 18 carbon atoms and 15 M is a solubilizing cation. The alkyl group R2 may have a - - mixture of chain lengths. It is preferred that at least two-thirds of the R2 alkyl groups have a chain length of 8 to 14 carbon atoms. This will be the case if R2 is coconut alkyl, for example. The solubilizing cation may be a range 20 of cations which are in general monovalent and confer water solubility. An alkali metal, notably sodium, is especially envisaged. Other possibilities are ammonium and substituted ammonium ions, such as trialkanolammonium or trialkylammonium. 25 Alkyl Ether Sulfates R30(CH2CH20)nS03M 30 where R3 is a primary alkyl group of 8 to 18 carbon atoms, n has an average value in the range from 1 to 6 and M is a WO 2005/054419 PCT/EP2004/013161 - 9 - solubilizing cation. The alkyl group R3 may have a mixture of chain lengths. It is preferred that at least two-thirds of the R3 alkyl groups have a chain length of 8 to 14 carbon atoms. This will be the case if R3 is coconut alkyl, for 5 example. Preferably n has an average value of 2 to 5. Ether sulfates have been found to provide viscosity build in certain of the formulations of this invention, and thus are considered a preferred ingredient. 10 Fatty Acid Ester Sulfonates R4CH(S03M)C02R5 Where R4 is an alkyl group of 6 to 16 atoms, R5 is an alkyl 15 group of 1 to 4 carbon atoms and M is a solubilizing cation. The group R4 may have a mixture of chain lengths. Preferably at least two-thirds of these groups have 6 to 12 carbon atoms. This will be the case when the moiety R8CH(-) C02 (-) is derived from a coconut source, for instance. It is 20 preferred that R5 is a straight chain alkyl, notably methyl or ethyl. Alkyl Benzene Sulfonates 25 R6ArS03M. where R6 is an alkyl group of 8 to 18 carbon atoms, Ar is a benzene ring (C6H4) and M is a solubilizing cation. The group R6 may be a mixture of chain lengths. A mixture of 30 isomers is typically used, and a number of different grades, such as "high 2-phenyl" and "low 2-phenyl" are commercially WO 2005/054419 PCT/EP2004/013161 - 10 - available for use depending on formulation needs. A plentitude of commercial suppliers exist for these materials, including Stepan (Northfield, 111.) and Witco (Greenwich, Conn.) Typically they are produced by the 5 sulfonation of alkylbenzenes, which can be produced by either the HF-catalyzed alkylation of benzene with olefins or an,AlCl3-catalyzed process that alkylates benzene with chloroparaffins, and are sold by, for example, Petresa (Chicago, 111.) and Sasol (Austin, Tex.). Straight chains 10 of 11 to 14 carbon atoms are usually preferred. Paraffin sulfonates having 8 to 22 carbon atoms, preferably 12 to 16 carbon atoms, in the alkyl moiety. They are usually produced by the sulfoxidation of petrochemically- 15 derived normal paraffins. These surfactants are commercially available as, for example, Hostapur SAS from Clariant (Charlotte, N.C.). Olefin sulfonates having 8 to 22 carbon atoms, preferably 12 20 to 16 carbon atoms. U.S. Patent No. 3,332,880 contains a description of suitable olefin sulfonates. Such materials are sold as, for example, Bio-Terge AS-40, which can be purchased from Stepan (Northfield, 111.). 25 Sulfosuccinate esters R7OOCCH2CH (S03~M+) COOR8 are also useful in the context of this invention. R7 and R8 30 are alkyl groups with chain lengths of between 2 and 16 carbons, and may be linear or branched, saturated or WO 2005/054419 PCT/EP2004/013161 - 11 - unsaturated. A preferred sulphosuccinate is sodium bis (2- ethylhexyl) sulfosuccinate, which is commercially available under the tradename Aerosol OT from Cytec Industries (West Paterson, N.J.). 5 Organic phosphate based anionic surfactants include organic phosphate esters such as complex mono- or diester phosphates of hydroxyl- terminated alkoxide condensates, or salts thereof. Included in the organic phosphate esters are 10 phosphate ester derivatives of polyoxyalkylated alkylaryl phosphate esters, of ethoxylated linear alcohols and ethoxylates of phenol. Also included are nonionic alkoxylates having a sodium alkylenecarboxylate moiety linked to a terminal hydroxyl group of the nonionic through 15 an ether bond. Counterions to the salts of all the foregoing may be those of alkali metal, alkaline earth metal, ammonium, alkanolammonium and alkylammonium types. Other preferred anionic surfactants include the fatty acid 20 ester sulfonates with formula: R9CH(S03M)C02R10 where the moiety R9CH(-)C02 (-) is derived from a coconut 25 source and R10 is either methyl or ethyl; primary alkyl sulfates with the formula: R11OS03M WO 2005/054419 PCT/EP2004/013161 - 12 - wherein R11 is a primary alkyl group of 10 to 18 carbon atoms and M is a sodium cation; and paraffin sulfonates, preferably with 12 to 16 carbon atoms to the alkyl moiety. 5 Other anionic surfactants preferred for use with this formulation include isethionates, sulfated triglycerides, alcohol sulfates, ligninsulfonates, naphthelene sulfonates and alkyl naphthelene sulfonates and the like. 10 AMPHIPHILIC CARBOXY CONTAINING POLYMER---- The amphiphilic carboxy containing polymers according to the present invention are anioinic polymers, such as, preferably, polyacrylates. "Anionic polymer" is defined as 15 a molecule with a molecular weight in excess of 10,000 daltons comprised of monomer units where at least- one of the monomer units making up the polymer contains a negative charge over a portion of the wash pH range of 6 to 11, and those monomer units not containing anionic charges being 20 nonionic in nature.. The amphiphilic carboxy containing polymers comprise monomers comprising a carboxylate or carboxylic acid group, said monomers being preferably selected from carboxylated 25 sugar units, carboxylated unsaturated units (like acrylate, methacrylate, itaconate, maleate and mixtures) and mixtures thereof. The amphiphilic carboxy containing polymer also contains monomer units which are uncharged. Preferably, these uncharged monomers are selected from vinylacetate, 30 vinylpyrrolidorte, vinylpyridine, vinylimidazol, styrene, WO 2005/054419 PCT/EP2004/013161 - 13 - alkyl – esters of the above carboxylate monomers (e. g. 1-20) alk(en)yl, preferably C5-16 alkyl) and mixtures thereof. More preferably, the amphiphilic carboxy containing polymers 5 are of the following type: styrene-acrylate copolymer, acrylate-alkylmethacrylate copolymers, ethoxylated ethacrylate-acrylate copolymer, methacrylate- vinylacetate copolymer or itaconate-vinylacetate copolymers. Examples of such polymers are Narlex LD55, Narlex H100, Narlex H1200 and 10 Narlex;DC1 (Narlex is a registered Trade Mark of National Starch)1. Additionally, the amphiphilic carboxy containing polymers may preferably be copolymers of ethoxylated maleate and 15 dodecene-1. An example thereof is Dapral GE 202 (Trade Mark). Optionally, the amphiphilic carboxy containing polymer is partly ethoxylated, e.g. with a PEG 350 side chain. 20 Most preferably, the amphiphilic carboxy containing polymers are selected from copolymers of acrylic acid and styrene.

PVP K-15 15 is preferred due to its relatively small molecular weight. Other suitable polyvinylpyrrolidones which are commercially available from BASF Corporation include Sokalan HP 165 (Trade Mark) and Sokalan HP 12 (Trade Mark). Polyvinylpyrrolidones will be known to persons skilled in 20 the detergent field; see for example EP-A-262,897 and EP-A-256,696. The level of the uncharged polymer in the inventive softening laundry composition is 0.05 % to 3%, preferably 25 0.25 % to 1.5%, for instance 0.3% by weight of the composition. CATIONIC POLYMER 30 A cationic polymer is here defined to include polymers which, because of their molecular weight or monomer WO 2005/054419 PCT/EP2004/013161 - 15 - composition, are soluble or dispersible to at least the extent of 0.01% by weight in distilled water at 25 °C. Water soluble cationic polymers include polymers in which one or more of the constituent monomers are selected from 5 the list of copolymerizable cationic or amphoteric monomers. These monomer units contain a positive charge over at least a portion of the pH range 6-11. A partial listing of monomers can be found in the "International Cosmetic Ingredient Dictionary," 5th Edition, edited by J.A. 10 Wenninger and G.N. McEwen, The Cosmetic, Toiletry, and Fragrance Association, 1993. Another source of such monomers can be found in "Encyclopedia of Polymers and Thickeners for Cosmetics", by R.Y. Lochhead and W.R. Fron, Cosmetics, & Toiletries, vol. 108, May 1993, pp 95-135. 15 The cationic polymers of this invention are effective at surprisingly low levels. As such, the ratio of cationic polymer to total surfactant in the composition should preferably be no greater than 1:5, and more preferably less 20 than 1:10. The ratio of cationic polymer to anionic surfactant in the composition, oh a mass basis, should be less than 1:4, and ideally less than 1:10, as well.

The remaining monomer units comprising the cationic polymer are chosen from the class of anionic monomers and the class of nonionic monomers or solely from the class of nonionic 5 monomers. In the former case, the polymer is an amphoteric polymer while in the latter case it can be a cationic polymer, provided that no amphoteric co-monomers are present.

A third, and highly 15 preferred, class of nonionic monomers includes naturally derived materials such as hydroxyethylcellulose and guar gum. It is highly preferred, and often necessary in the case of 20 certain compositions, to formulate the products of this invention with the proper ratio of cationic polymer to anionic surfactant. Too high a ratio can result in reduced softening, poor packing at the interface, unacceptable dissolution times and, in the case of liquid products, an 25 excessively high viscosity which can render the product non-pourable, and thus unacceptable for consumer use. The use of lower ratios of cationic polymer to surfactant also reduces the overall level of polymer necessary for the formulation, which is also preferable for cost and 30 environmental reasons, and gives the formulator greater flexibility in making a stable product. The preferred ratio WO 2005/054419 PCT/EP2004/013161 - 23 - —of cationic polymer : total surfactant will be less than 1:4, whereas the preferred ratio of cationic polymer : anionic surfactant will be less than 1:5, and the preferred ratio of cationic polymer : nonionic surfactant will be less 5 than 1:5. More preferably, the ratios of cationic polymer : total surfactant, cationic polymer : anionic surfactant and cationic polymer: total surfactant will be less than 1:10. In terms of absolute fraction, this often means that the concentration of cationic polymer will generally be less 10 than 5%, preferably less than 2% and most preferably less than 1% of the total product mass. Without wishing to be bound by theory, it is believed that the species responsible for providing a conditioning benefit 15 in these formulations is a polymer / surfactant complex. The compositions of this invention will preferably comprise at least 2%, more preferably at least 5%, and most preferably at least 10% of one or more surfactants with a hydrophilic/lipophilic balance (HLB, defined in U.S. Pat. 20 No. 6,461,387) of more than 4. Many of the aforementioned cationic polymers can be synthesized in, and are commercially available in, a number of different molecular weights. In order to achieve optimal 25 cleaning and softening performance from the product, it is desirable that the water-soluble cationic or amphoteric polymer used in this invention be of an appropriate molecular weight. Without wishing to be bound by theory, it is believed that polymers that are too high in mass can 30 entrap soils and prevent them from being removed. The use of cationic polymers with an average molecular weight of WO 2005/054419 PCT/EP2004/013161 - 24 - less than 850,000 daltons, and especially those with an average molecular weight of less than 500,000 daltons can help to minimize this effect without significantly reducing the softening performance of properly formulated products. 5 On the other hand, polymers with a molecular weight of 10,000 daltons or less are believed to be too small to give an effective softening benefit. Conditioning Benefits 10 The compositions of this invention are intended to confer conditioning benefits to garments, home textiles, carpets and other fibrous or fiber-derived articles. These formulations are not to be limited to conditioning benefits, 15 however, and will often be multi-functional. The primary conditioning benefit afforded by these products is softening. Softening includes, but is not limited to, an improvement in the handling of a garment treated with the 20 compositions of this invention relative to that of an article laundered under identical conditions but without the use of this invention. Consumers will often describe an article that is softened as "silky" or "fluffy", and generally prefer the feel of treated garments to those that 25 are unsoftened. It is desirable that the formulae of this invention, when used as instructed, yield a softness parameter of more than 70. The preferred products give a softness parameter of more than 80. 30 The conditioning benefits of these compositions are not limited to softening, however. They may, depending on the WO 2005/054419 PCT/EP2004/013161 - 25 - particular—embodiment of the invention selected,—also provide an antistatic benefit. In addition to softening, the cationic polymer / anionic surfactant compositions of this invention are further believed to lubricate the fibers 5 of textile articles, which can reduce wear, pilling and color fading, and provide a shape-retention benefit. This lubricating layer may also, without wishing to be bound by theory, provide a substrate on the fabric for retaining fragrances and other benefit agents. Furthermore, the 10 cationic polymers of this invention are also believed to inhibit the transfer, bleeding and1loss of vagrant dyes from fabrics during the wash, further improving color brightness over time. 15 Form of the Invention The present invention can take any of a number of forms, including a dilutable fabric conditioner, that may be an isotropic liquid, a surfactant-structured liquid or any 20 other laundry detergent form known to those skilled in the art. A "dilutable fabric conditioning" composition is defined, for the purposes of this disclosure, as a product intended to be used by being diluted with water or a nonaqueous solvent by a ratio of more than 100:1, to produce a 25 liquor suitable for treating textiles and conferring to them one or more conditioning benefits. As such, compositions intended to be used as combination detergent / softeners, along with fabric softeners sold for application in the final rinse of a wash cycle and fabric softeners sold for 30 application at the beginning of a wash cycle are all considered within the scope of this invention. For all WO 2005/054419 PCT/EP2004/013161 - 26 - cases, however, these compositions are intended to be used by being diluted by a ratio of more than 100:1 with water or a non-aqueous solvent, to form a liquor suitable for treating fabrics. Particularly preferred forms of this invention include combination 'detergent / softener products, especially as a liquid, and isotropic or surfactant-structured liquid products intended for application as a fabric softener during the wash cycle or the final rinse. For the purposes of this disclosure, the term "fabric softener" shall be understood to mean a consumer or industrial product added to the wash, rinse or dry cycle of a laundry process for the express or primary purpose of conferring one or more conditioning benefits. The pH range of the composition is 2 to 12. As many cationic polymers can decompose at high pH, especially when they contain amine or phosphine moieties, it is desirable to 20 keep the pH of the composition below the pKa of the amine or phosphine group that is used to quaternize the selected polymer, below which the propensity for this to occur is greatly decreased. This reaction can cause the product to lose effectiveness over time and create an undesirable 25 product odor. As such, a reasonable margin of safety, of 1-2 units of pH below the pKa should ideally be used in order to drive the equilibrium of this reaction to strongly favor polymer stability. Although the preferred pH of the product will depend on the particular cationic polymer selected for 30 formulation, typically these values should be below 8.5 to 10. Wash liquor pH, especially in the case of combination WO 2005/054419 PCT/EP2004/013161 - 27 - detergent / softener products, can often be less important, as the kinetics of polymer decomposition are often slow, and the time of one wash cycle is typically not sufficient to allow for this reaction to have a significant impact on the 5 performance or odor of the product. ' A lower pH can also aid in the formulation of higher-viscosity products. Conversely, as the product depends on the presence of soluble anionic surfactants to provide softening, its pH 10 should preferably be above the pKa of the surfactant acids used to formulate it. In addition, aqueous detergent products, which are a highly preferred embodiment of this invention, are nearly impossible to formulate below the pKa of the surfactant acids used, as these molecules are rather 15 insoluble in water when in acid form. Again, it-is especially desirable to have the pH at least 1-2 units above the pKa of the surfactant acids, to ensure that the vast majority of anionic surfactant is present in salt form. Typically, this will suggest that the product pH should be 20 above 4, although in certain cases, such as when carboxylic acid salts, which often have a pKa around 4 or 5 ,are used, the pH of the product can need to be above 7 or 8 to ensure effective softening. 25 The formulation may be buffered at the target pH of the composition. Method of Use 30 The following details a method for conditioning textiles comprising the steps, in no particular order of: WO 2005/054419 PCT/EP2004/013161 - 28 - a. providing a laundry detergent or fabric softener composition comprising at least one anionic surfactant and at least one cationic 5 polymer, in a ratio and concentration to effectively soften and condition fabrics under predetermined laundering conditions; and an anti-redeposition system including PVP and an amphiphilic carboxy containing polymer; 10 b. contacting one or more articles with the composition at one or more points during a laundering process; and 15 c. allowing the articles to dry or mechanically- tumble-drying them. The softening parameter is greater than 70, preferably greater than 80, and the composition comprises more than 5% 20 by weight of one or more anionic surfactants having an HLB of greater than 4. Amounts of composition used will generally range between 10g and 300g total product per 3 kg of conditioned fibrous 25 articles, depending oh the particular embodiment chosen and other factors, such as consumer preferences, that influence product use behavior. A consumer that would use the present invention could also 30 be specifically instructed to contact the fabrics with the inventive composition with the purpose of simultaneously WO 2005/054419 PCT/EP2004/013161 - 29 - cleaning and softening the said fabrics. This approach would be recommended when the composition takes the form of a softening detergent to be dosed at the beginning of the wash cycle. 5 Insoluble Matter It is preferred that the compositions of this disclosure be formulated with low levels, if any at all, of any matter 10 that is substantially insoluble in the solvent intended to be used to dilute the product. For the purposes of this disclosure, "substantially insoluble" shall mean that the material in question can individually be dissolved at a level of less than 0.001% in the specified solvent. 15 Examples of substantially insoluble matter in aqueous systems include, but are not limited to aluminosilicates, pigments, clays and the like. Without wishing to be bound by theory, it is believed that solvent-insoluble inorganic matter can be attracted and coordinated to the cationic 20 polymers of this invention, which are believed to attach themselves to the articles being washed. When this occurs, it is thought that these particles can create a rough effect on the fabric surface, which in turn reduces the perception of softness. 25 In addition, as liquid compositions are a preferred embodiment of this invention, and insoluble matter is often difficult to formulate into a liquid, it is further desirable to minimize its level in the product. For this 30 invention it is desirable to have the liquid compositions be substantially transparent for esthetic reasons. Thus, for WO 2005/054419 PCT/EP2004/013161 -3- the compositions of this invention it is desirable to have a percent transmittance of light of greater than 50 using a 1 centimeter cuvette at a wavelength of 570 nanometers wherein the composition is measured in the absence of dyes. 5 Alternatively, transparency of the composition may be measured as having an absorbence (A) at 570 nanometers of less than 0.3 which is in turn equivalent to percent transmittance of greater than 50 using the same cuvette as above. The relationship between absorbance and percent 10 transmittance is: Percent Transmittance = 100(1/inverse log A) Preferably/ insoluble and substantially insoluble matter 15 will be limited to less than 10% of the composition, more preferably to 5%. Most preferably, especially in the case of liquid conditioning compositions, the composition will be essentially free, or have less than 5%, of substantially insoluble matter or precipitation. 20 Optional Ingredients In addition to the above-mentioned essential elements, the formulator may include one or more optional ingredients, 25 which are often very helpful in rendering the formulation more acceptable for consumer use. Examples of optional components include, but-are not limited to: nonionic surfactants, amphoteric and zwitterionic 30 surfactants, cationic surfactants, hydrotropes, fluorescent whitening agents, photobleaches, fiber lubricants, reducing WO 2005/054419 PCT/EP2004/013161 - 31 - agents,—enzymes,—enzyme stabilizing agents, powder finishing agents, defoamers, builders, bleaches, bleach catalysts, soil release agents, dye transfer inhibitors, buffers, colorants, fragrances, pro-fragrances, rheology modifiers, 5 anti-ashing polymers, preservatives, insect repellents, soil repellents, water-resistance agents, suspending agents, aesthetic agents, structuring agents, sanitizers, solvents, fabric finishing agents, dye fixatives, wrinkle-reducing agents, fabric conditioning agents and deodorizers. 10 Preservatives Optionally, a soluble preservative may be added to this invention. The use of a preservative is especially 15 preferred when the composition of this invention is a liquid, as these products tend to be especially susceptible to microbial growth. The use of a broad-spectrum preservative, which controls the 20 growth of bacteria and fungi is preferred. Limited-spectrum preservatives, which are only effective on a single group of microorganisms may also be used, either in combination with a broad-spectrum material or in a "package" of limited-spectrum preservatives with additive activities. Depending 25 on the circumstances of manufacturing and consumer use, it may also be desirable to use more than one broad-spectrum preservative to minimize the effects of any potential contamination. 30 The use of both biocidal materials, i.e. substances that kill or destroy bacteria and fungi, and biostatic WO 2005/054419 PCT/EP2004/013161 - 32 - preservatives, i.e. substances that regulate or retard the growth of microorganisms, may be indicated for this invention. 5 In order to minimize environmental waste and allow for the maximum window of formulation stability, it is preferred that preservatives that are effective at low levels be used. Typically, they will be used only at an effective amount. For the purposes of this disclosure, the term "effective 10 amount" means a level sufficient to control microbial growth in the product for a specified period of time, i.e., two weeks, such that the stability and physical properties of it are hot negatively affected. For most preservatives, an effective amount will be between 0.00001% and 0.5% of the 15 total formula, based on weight. Obviously, however, the effective level will vary based on the material used, and one skilled in the art should be able to select an appropriate preservative and use level. 20 Preferred preservatives for the compositions of this invention include organic sulfur compounds, halogenated materials, cyclic organic nitrogen compounds, low molecular weight aldehydes, quaternary ammonium materials, dehydroacetic acid, phenyl and phenoxy compounds and 25 mixtures thereof. Examples of preferred preservatives for use in the compositions of the present invention include: a mixture of 77% 5-chloro-2-methyl-4-isothiazolin-3-one and 23% 2- 30 methyl-4-isothiazolin-3-one, which is sold commercially as a 1.5% aqueous solution by Rohm & Haas (Philadelphia, Pa.) WO 2005/054419 PCT/EP2004/013161 - 33 - under-the trade name Kathon; 1,2-benzisothiazolin 3-one, which is sold commercially by Avecia (Wilmington, Del.) as, for example, a 20% solution in dipropylene glycol sold under the trade name Proxel GXL; and a 95:5 mixture of 1,3 bis 5 (hydroxymethyl)-5,5-dimethyl-2,4 imidazolidinedione and 3-butyl-2-iodopropynyl carbamate, which can be obtained, for example, as Glydant Plus from Lonza (Fair Lawn, N.J.). WO 2005/054419 PCT/EP2004/013161 - 34 - Nonionic Surfactants Nonionic surfactants are useful in the context of this invention to both improve the cleaning properties of the 5 compositions, when used as a detergent, and to contribute to product stability. For the purposes of this disclosure, "nonionic surfactant" shall be defined as amphiphilic molecules with a molecular weight of less than 10,000, unless otherwise noted, which are substantially free of any 10 functional groups that exhibit a net charge at the normal wash pH of 6-11. Any type of nonionic surfactant may be used, although preferred materials are further discussed below. 15 Fatty Alcohol Ethoxylates: R180(EO)n Wherein R18 represents an alkyl chain of between 4 and 30 20 carbon atoms, (EO) represents one unit of ethylene oxide monomer and n has an average value between 0.5 and 20. R may be linear or branched. Such chemicals are generally produced by oligomerizing fatty alcohols with ethylene oxide in the presence of an effective amount catalyst, and are 25 sold in the market as, for example, Neodols from Shell (Houston, Tex.) and Alfonics from Sasol (Austin, Tex.). The fatty alcohol starting materials, which are marketed under trademarks such as Alfol, Lial and Isofol from Sasol (Austin, Tex.) and Neodol, from Shell, may be manufactured 30 by any of a number of processes known to those skilled in the art, and can be derived from natural or synthetic WO 2005/054419 PCT/EP2004/013161 - 35 - sources or a combination thereof.—-Commercial alcohol ethoxylates are typically mixtures, comprising varying chain lengths of R18 and levels of ethoxylation. Often, especially at low levels of ethoxylation, a substantial amount of 5 unethoxylated fatty alcohol remains in the final product, as well. Because of their excellent cleaning, environmental and stability profiles, fatty alcohol ethoxylates wherein R18 10 represents an alkyl chain from 10-18 carbons and n is an average number between 5 and 12 are highly preferred. Alkylphenol Ethoxylates: 15 R19ArO(EO)n Where R19 represents a linear or branched alkyl chain ranging from 4 to 30 carbons, Ar is a phenyl (C6S4) ring and (E0)n is an oligomer chain comprised of an average of n moles of 20 ethylene oxide. Preferably, R19 is comprised of between 8 and 12 Carbons, and n is between 4 and l2. Such materials are somewhat interchangeable with alcohol ethoxylates, and serve much the same function. 'A commercial example of an alkylphenol ethoxylate suitable for use in this invention is 25 Triton X-100, available from Dow Chemical (Midland, Mich.) Ethylene Oxide / Propylene Oxide Block Polymers: (EO)x(PO)y(EO)x or (PO)x(E0)y(PO)x 30 WO 2005/054419 PCT/EP2004/013161 - 36 - wherein EO represents an ethylene oxide unit, PO represents a propylene oxide unit, and x and y are numbers detailing the average number of moles ethylene oxide and propylene oxide in each mole of product. Such materials tend to have 5 higher molecular weights than most nonionic surfactants, and as such can range between 1,000 and 30,000 daltons. BASF (Mount Olive, N.J.) manufactures a suitable set of derivatives and markets them under the Pluronic and Pluronic-R trademarks. 10 Other nonionic surfactants should also be considered within the scope of this invention. These include condensates of alkanolamines with fatty acids, such as cocamide DEA, polyol-fatty acid esters, such as the Span series available 15 from Uniqema (Wlimington, Del.), ethoxylated polyol-fatty acid esters, such as the Tween series available from Uniqema (Wilmington, Del.), Alkylpolyglucosides, such as the APG line available from Cognis (Gulph Mills, Pa.) and n-alkylpyrrolidones, such as the Surfadone series of products 20 marketed by ISP (Wayne, N.J). Furthermore, nonionic surfactants not specifically mentioned above, but within the definition, may also be used. Fluorescent Whitening Agents 25 Many fabrics, and cottons in particular, tend to lose their whiteness and adopt a yellowish tone after repeated washing. As such, it is customary and preferred to add a small amount of fluorescent whitening agent', which absorbs light in the 30 ultraviolet region of the spectrum and re-emits it in the visible blue range, to the compositions of this invention, WO 2005/054419 PCT/EP2004/013161 - 37 - especially if they are combination detergent / fabric conditioner preparations. Suitable fluorescent whitening agents include derivatives of diaminostilbenedisulfonic acid and their alkali metal salts. Particularly, the salts of 5 4,4'-bis(2-anilino4-morpholino-l, 3, 5-triazinyl-6- amino)stilbene-2,2'-disulfonic acid, and related compounds where the morpholino group is replaced by another nitrogen-comprising moiety, are preferred. Also preferred are brighteners of the 4,4'-bis(2-sulfostyryl) biphenyl type, 10 which, may optionally be blended with other fluorescent whitening agents at the option of the formulator. Typical fluorescent whitening agent levels in the preparations of this invention range between 0.001% and 1%, although a level between 0.1% and 0,3%, by mass, is normally used. 15 Commercial supplies of acceptable fluorescent whitening agents can be sourced from, for example, Ciba Specialty Chemicals (High Point, N.C.) and Bayer (Pittsburgh, Pa.). Builders 20 Builders are often added to fabric cleaning compositions to complex and remove alkaline earth metal ions, which can interfere with the cleaning performance of a detergent by combining; with anionic surfactants and removing them from 25 the wash liquor. The preferred compositions of this invention, especially when used as a combination detergent / softener, contain builders. Soluble builders, such as alkali metal carbonates and alkali 30 metal citrates, are particularly preferred, especially for the liquid embodiment of this invention. Other builders, as WO 2005/054419 PCT/EP2004/013161 - 38 - further detailed below, may also be used, however. Often a mixture of builders, chosen from those described below and others known to those skilled in the art, will be used. 5 Alkali and Alkaline Earth Metal Carbonates: Alkali and alkaline earth metal carbonates, such as those detailed in German patent application 2,321,001, published Nov. 15, 1973, are suitable for use as builders in the 10 compositions of this invention. They may be supplied and used either in anhydrous form, or including bound water. Particularly useful is sodium carbonate, or soda ash, which both is readily available on the commercial market and has "ah excellent environmental profile. 15 The sodium carbonate used in this invention may either be natural or synthetic, and, depending on the needs of the formula, may be used in either dense or light form. Natural soda ash is generally mined as trona and further refined to 20 a degree specified by the needs of the product it is used in. Synthetic ash, on the other hand, is usually produced via the Solvay process or as a coproduct of other manufacturing operations, such as the synthesis of caprolactam. It is sometimes further useful to include a 25 small amount of calcium carbonate in the builder formulation, to seed crystal formation and increase building efficacy. WO 2005/054419 PCT/EP2004/013161 - 39 - Organic Builders: Organic detergent builders can also be Used as nonphosphate builders in the present invention. Examples of organic 5 builders include alkali metal citrates, succinates, malonates, fatty acid sulfonates, fatty acid carboxylates, nitrilotriacetates, oxydisuccinates, alkyl and alkenyl disuccihates, oxydiacetates, carboxymethyloxy succinates, ethylenediamine tetraacetates, tartrate monosuccinates, 10 tartrate disuccinates, tartrate monoacetates, tartrate diacetates, oxidized starches, oxidized heteropolymeric polysaccharides, polyhydroxysulfonates, polycarboxylates such as polyacrylates, polymaleates, polyacetates, polyhydroxyacrylates, polyacrylate/polymaleate and 15 polyacrylate/ polymethacrylate copolymers, acrylate/maleate/vinyl alcohol terpolymers, aminopolycarboxylates and polyacetal carboxylates, and polyaspartates and mixtures thereof. Such carboxylates are described in U.S. Patent Nos. 4,144,226, 4,146,495 and 20 4,686,062. Alkali metal citrates, nitrilotriacetates, oxydisuccinates, acrylate/maleate copolymers and acrylate/maleate/vinyl alcohol terpolymers are especially preferred nonphosphate builders. 25 Phosphates: The compositions of the present invention which utilize a water-soluble phosphate builder typically contain this builder at a level of from 1 to 90% by weight of the 30 composition. Specific examples of water-soluble phosphate builders are the alkali metal tripolyphosphates, sodium, WO 2005/054419 PCT/EP2004/013161 - 40 - potassium and ammonium pyrophosphate, sodium and potassium orthophosphate, sodium polymeta/phosphate in which the degree' of polymerization ranges from 6 to 21, and salts of phytic acid. Sodium or potassium tripolyphosphate is most 5 preferred. Phosphates are, however, often difficult to formulate, especially into liquid products, and have been identified a potential agents that may contribute to the eutrophication 10 of lakes and other waterways. As such, the preferred compositions of this invention comprise phosphates at a level of less than 10% by weight, more preferably less than 5% by weight. The most preferred compositions of this invention are formulated to be substantially free of 15 phosphate builders. Zeolites: Zeolites may -also be used as builders in the present 20 invention. A number of zeolites suitable for incorporation into the products of this disclosure are available to the formulator, including the common zeolite 4A. In addition, zeolites of the MAP variety, such as those taught in European Patent Application EP 384,070B, which are sold 25 commercially by, for example, Ineos Silicas (UK), as Doucil A24, are also acceptable for incorporation. MAP is defined as an alkali metal aluminosilicate of zeolite P type having a silicon to aluminium ratio not exceeding 1.33, preferably within the range of from 0.90 to 1.33, more preferably 30 within the range of from 0.90 to 1.20. WO 2005/054419 PCT/EP2004/013161 - 41 - Especially preferred is zeolite MAP having a silicon to aluminium ratio not exceeding 1.07, more preferably 1.00. The particle size of the zeolite is not critical. Zeolite A or zeolite MAP of any suitable particle size may be used. 5 In any event, as zeolites are insoluble matter, it is advantageous to minimize their level in the compositions of this invention. As such, the preferred formulations contain less than 10% of zeolite builder, while especially preferred compositions comprise less than 5% zeolite. 10 Enzyme Stabilizers When enzymes, and especially proteases are used in liquid detergent formulations, it is often necessary to include a 15 suitable quantity of enzyme stabilizer to temporarily deactivate it until it is used in the wash. Examples of suitable enzyme stabilizers are well-known to those skilled in the art, and include, for example, borates and polyols such as, propylene glycol. Borates are especially suitable 20 for use as enzyme stablizers because in addition to this benefit, they can further buffer the pH of the detergent product over a wide range, thus providing excellent flexibility. 25 If a borate-based enzyme stabilization system is chosen, along with one or more cationic polymers that are at least partially comprised of carbohydrate moeities, stability problems tan result if suitable co-stablizers are not used. It is believed that this is the result of borates' natural 30 affinity for hydroxyl groups, which can create an insoluble borate-polymer complex that precipitates from solution WO 2005/054419 PCT/EP2004/013161 - 42 - either over time or at cold temperatures. Incorporating into the formulation a co-stabilizer, which is normally a diol or polyol, sugar or other molecule with a large number of hydroxyl groups, can ordinarily prevent this. Especially 5 preferred for use as a co-stabilizer is sorbitol, used at a level that is at least 0.8 times the level of borate in the system, more preferably 1.0 times the level of borate in the system and most preferably more than 1.4 3 times the level of borate in the system, is sorbitol, which is effective, 10 inexpensive, biodegradable and readily available on the market. Similar materials including sugars such as glucose and sucrose, and other poyols such as propylene glycol, glycerol", mannitol, maltitol and xylitol, should also be considered within the scope of this invention. 15 Fiber Lubricants In order to enhance the conditioning, softening, wrinkle-reduction and protective effects of the compositions of this 20 invention, it is often desirable to include one or more fiber lubricants in the formulation. Such ingredients are well known to those skilled in the art, and are intended to reduce the coefficient of friction between the fibers and yarns in articles being treated, both during and after the 25 wash process. This effect can in turn improve the consumer's perception of softness, minimize the formation of wrinkles and prevent damage to textiles during the wash. For the purposes of this disclosure, "fiber lubricants" shall be considered non-cationic materials intended to 30 lubricate fibers for the purpose of reducing the friction between fibers or yarns in an article comprising textiles WO 2005/054419 PCT/EP2004/013161 - 43 - which-provide one—or more wrinkle--reduction,—fabric -conditioning, .or protective benefit. Examples of suitable fiber lubricants include oily sugar 5 derivatives, functionalized plant and animal-derived oils, silicones, mineral oils, natural and synthetic waxes and the like. Such ingredients often have low HLB values, less than 10, although exceeding this level is not outside of the scope of this invention. 10 Oily sugar derivatives suitable for use in this invention are taught in WO 98/16538, which are especially preferred as fiber lubricants, due to their ready availability and favorable environmental profile. When used in the 15 compositions of this invention, such materials are typically present at a level between 1% and 10% of the finished composition. Another class of acceptable ingredients includes hydrophilically-modified plant and animal oils and synthetic triglycerides. Suitable and preferred 20 hydrophilically modified plant, animal, and synthetic triglyceride oils and waxes have been identified as effective fiber lubricants. Such suitable plant derived triglyceride materials include hydrophilically modified triglyceride oils, e.g. sulfated, sulfonated, carboxylated, 25 alkoxylated, esterified, saccharide modified, and amide derivatized oils, tall oils and derivatives thereof, and the like. Suitable animal derived triglyceride materials include hydrophilically modified fish oil, tallow, lard, and lanolin wax, and the like. An especially preferred 30 functionalized oil is sulfated castor oil, which is sold WO 2005/054419 PCT/EP2004/013161 - 44 - commercially as, for example, Freedom SCO-75, available from Noveon (Cleveland, Ohio). Various levels of derivatization may be used provided that 5 the derivatization level is sufficient for the oil or wax derivatives to become soluble or dispersible in the solvent it is used in so as to exert a fiber lubrication effect during laundering of fabrics with a detergent containing the oil or wax derivative. 10 If this invention includes a functionalized oil of synthetic origin, preferably this oil is a silicone oil. More preferably, it is either a silicone poly ether or amino-functional silicone. If this invention incorporates a 15 silicone polyether, it is preferably of one of the two general structures shown below: Where PE represents: Structure A where Me represents methyl; EO represents ethylene oxide; PO represents 1, 2 propylene oxide; z represents either a 20 hydrogen or a lower alkyl radical; x, y, m, n are constants WO 2005/054419 PCT/EP2004/013161 - 45 - and can be varied to alter the properties of the functionalized silicone. A molecule of either structure can be used for the purposes 5 of this invention. Preferably, this molecule contains more than 30% silicone, more than 20% ethylene oxide and less than 30% propylene oxide by weight, and has a molecular weight of more, than 5,000. An example of a suitable, commercially available such material is L-7622, available 10 from Crompton Corporation, (Greenwich, Ct.) When the use of a fiber lubricant is elected, it will generally be present as between 0.1% and 15% of the total composition weight. 15 Bleach Catalyst An effective amount of a bleach catalyst can also be present in the invention.

Hydrotropes 10 In many liquid and powdered detergent compositions, it is customary to add a hydrotrope to modify product viscosity and prevent phase separation in liquids, and ease dissolution in powders. Two types of hydrotropes are 15 typically used in detergent formulations and are applicable to this invention. The first of these are short-chain functionalized amphiphiles. Examples of short-chain amphiphiles include the alkali metal salts of xylenesulfonic acid, cumenesulfonic acid and octyl sulfonic acid, and the 20 like. In addition, organic solvents and monohydric and polyhydric alcohols with a molecular weight of less than 500, such as, for example, ethanol, isoporopanol, acetone, propylene glycol and glycerol, may also be used as hydrotropes. 25 The following examples will more fully illustrate the embodiments of this invention. All parts, percentages and proportions referred to herein and in the appended claims are by weight unless otherwise illustrated. Physical test 30 methods are described below. WO 2005/054419 PCT/EP2004/013161 - 49 - TEST METHOD AND EXAMPLES Cleaning, Redeposition, and Graying 5 Cleaning, redeposition, and graying examples were generated under the following conditions: - 17 gallons of water per wash; 35 deg. Celcius wash - cold water rinse; 12 minutes per wash - tumble dried after each wash; 6 pounds of total fabric per wash (comprises an 11" x 11" cloth for 10 visualizing graying and the balance white cotton sheets -the 11" x 11" cloth is a terry towel named TIC-439 and is available from Textile Innovators of Charlotte, North Carolina); any chemicals that may have been on the fabrics were removed by washing 3 times with liquid all™ detergent 15 prior to use; each wash contained 5g of Georgia clay that is sewn into a 2" x 2" cotton fabric pouch (~2" X 2"). To measure the extent of graying, spectrophotometer readings were taken on terry towels after 3 repeat wash /dry cycles 20 with a given detergent using a Hunter Spectrophotometer. The L,a,b scale was used to measure cleaning. Graying results were reported as delta E values (AE) using the following calculation: 25 where, 30 L measures black to white differences, a measures green to red differences WO 2005/054419 PCT/EP2004/013161 - 50 - and, b measures blue to yellow differences. The larger the (delta E) ΔE value, the more gray is the terry towel. Greater than a 1-2 unit difference can be seen 5 visually. The pH for formulations 1-6 can range between 7.5 and 9.5 with 8.5 being most preferred. The pH for formulation 7 can range between 10.5 and 12.5 with 11.5 being most preferred. 10 Softening Fabric was washed with a variety of product, the formulations for which are set forth hereinbelow. The 15 washed fabric was then tested by consumer panels for perceived-softening. For each of the washes, product was added to a top loading Whirlpool washing machine that contained 17 gallons of water and 6 pounds of fabric. There were several 86% cotton/14% polyester hand towels in each 20 machine along with 100% cotton sheets to bring the total weight of the fabric to 6 pounds. The temperature of the water for the washes was 32 deg. C and the fabrics were washed for 12 minutes. After the rinse cycle, the fabrics were tumble dried. Two washes were done with each product. 25 Each formula tested is benchmarked against two controls - one using a model detergent (dosed at 130g at the beginning of the wash), and one using a model detergent plus a model liquid fabric softener. For the latter control, 100g of the softening formula is added at the beginning of the rinse 30 cycle. The formulae for the model detergents are shown in the tables below: WO 2005/054419 PCT/EP2004/013161 - 51 - TABLE 1.

Model Liquid Fabric Softener Ingredient Percent in Formula (based on 100% active) Dihydrogenated tallow dimethyl ammonium chloride 3.5 lactic acid 0.015 Calcium chloride 0.015 Water to 100 10 Five panelists scored the softness of the hand towels on a 0-10 scale with 0 being "not soft at all" and 10 being "extremely soft". Duplicate panels were run based on the duplicate, washes and the scores averaged over the two runs. 15 A Softening Parameter (SP) was then calculated using the following formula: SP = [(St - Sd)/(SC - Sd)] x 100 WO 2005/054419 PCT/EP2004/013161 - 52 - Where,St is the softening score for the formula being tested Sd is the softening score for model detergent, and Sc is the softening score for the model detergent 5 model liquid fabric softener. EXAMPLE 1 This example demonstrates that inclusion of a cationic 10 polymer in the detergent is the cause of redeposition of the particulate soil. The following two formulas were tested for graying - formulation 1 did not contain cationic polymer, while formulation 2 did contain cationic polymer. 15 TABLE 3.

ΔE for formulation 1 (no cationic polymer) was less than 2, while for formulation 2(containing cationic polymer),ΔE was 12. 10 EXAMPLE 2 Examples 2 and 3' illustrate how the antiredeposition performance of fabric softening compositions comprising 15 cationic polymers can be improved without negatively impacting their conditioning properties. The following formulas were tested for graying: WO 2005/054419 PCT/EP2004/013161 - 54 - TABLE 5.

Graying Results 15 Formulation Delta E 3 12 4 12 5 7 20 As can be seen from the tables above, only the combination of PVP and Alcosperse significantly reduces the amount of redeposition of clay to the terry towels. EXAMPLE 3 This example demonstrates that certain anionic polymers, but not the polymers identified in this application, are prone to deactivating the fabric softening ability of cationic polymers when formulated into liquid detergent products. Formulations 6-9 were prepared and tested for softening, and compared with Formulation 2 as shown in the table below. WO 2005/054419 PCT/EP2004/013161 - 55 - TABLE 7. Formulations 6 - 9 Formulation Number Description Softening Parameter 2 101 6 Formulation 2 plus 0.3% Flexan 130 1 22 7 Formulation 2 plus 0.3% low molecular-weight polystyrene sulfonate 2 10 8 Formulation 2 plus 0.3% Kelzan HP 3 65 9. . ■■ Formulation 2 plus 0.3% Alcosperse 725 4 104 1A high-molecular-weight polystyrene sulfonate ,available from the National Starch and Chemical Company, which is a division of Imperial Chemical Industries, Bridgewater, NJ. 5 2Available from the National Starch and Chemical Company, which is a division of Imperial Chemical Industries, Bridgewater, NJ. 3Xanthan gum, available from CP Kelco, San Diego, CA. 4A polyacrylate available from the Alco division of National Starch and Chemical Co. which is a division of Imperial Chemical Industries, 10 Chattanooga, TN. These results demonstrate that ordinarily, cationic polymers will complex with anionic polymers, leading to a significant reduction in their ability to soften. Surprisingly, 15 however, Alcosperse 725, and similar acrylate polymers are able to both give an antiredeposition benefit and retain the softening benefit of the original formulaiton. The data in Examples 2 and 3 show that using a cationic 20 polymer and anionic surfactant, in combination with PVP and an amphiphilic carboxy substituted polymer, can improve anti-redeposition performance without negatively impacting softening.
