FORM - 2 THE PATENTS ACT, 1970 (39 of 1970) & The Patents Rules, 2006 COMPLETE SPECIFICATION (See Section 10 and Rule 13) SOLID LAUNDRY DETERGENTS WITH POLYANIONIC AMMONIUM SURFACTANT 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 2005/095572 PCT/EP2005/001172 SOLID LAUNDRY DETERGENTS WITH POLYANIONIC AMMONIUM SURFACTANT 5 FIELD OF THE INVENTION The present invention relates to solid laundry detergent 10 compositions comprising a polyanionic ammonium surfactant. BACKGROUND OF THE INVENTION 15 Despite numerous laundry detergent products on the market, a continuous consumer need exists for improved performance, especially if such can be achieved at a lower cost. 20 Specifically, consumers look for improved soil removal and improved whiteness and brightness, without having to pay a premium for such benefits. Polyamines, such as tetraethylene pentamine ("TEPA"), are known in petroleum production and refining operations as corrosion inhibitors, 25 demulsifiers, neutralizers, and functional additives. Laundry applications use modified polyamines. See for instance, WO 00/63334, EP 137 615, US Patent 5,669,984, US Patent 4,664,848, WO 99/49009, US Patent 6,121,226, US Patent 4,622,378, and US Patent 4,597,898. Some of these 30 documents describe detergent compositions which also incorporate anionic surfactants or fatty acids, or anionic surfactant precursors, in the presence also of strong caustic agents which are added to produce anionic surfactants from anionic surfactant acid precursors or fatty 35 acid salts from fatty acids. The present invention is based WO 2005/095572 PCT/EP2005/001172 - 2 - at least in part on the discovery that polyanionic ammonium surfactants (PAAS) employed in the present invention exhibit different characteristics and perform substantially better at soil removal than physical mixtures of anionic 5 surfactants/fatty acids and polyamines. The present invention is also based at least in part on the discovery that polyanionic ammonium surfactants may be formulated into granules with improved properties, including solubility. The present invention is further based at least in part on 10 the discovery that PAAS may be incorporated into a powder detergent composition containing high level of an alkaline ingredient with pKa greater than or equal to 10. SUMMARY OF THE INVENTION 15 The present invention includes a solid laundry detergent composition comprising granules, the granules comprising: 20 25 (a) from about 0.1% to about 80%, by weight of the composition, of a polyanionic ammonium surfactant; (b) from about 0.2% to about 40%, by weight of the composition, of a solid acid; (c) from about 1% to about 85%, by weight of the composition, of an ingredient selected from the group consisting of bicarbonate, carbonate, per carbonate and mixtures thereof. The PAAS granules may be used as an adjunct or as a whole formulated powder detergent. 30 WO 2005/095572 PCT/EP2005/001172 - 3 - DETAILED DESCRIPTION OF THE INVENTION Except in the operating and comparative examples, or where otherwise explicitly indicated, all numbers in this 5 description indicating amounts of material or conditions of reaction, physical properties of materials and/or use are to be understood as modified by the word "about." All amounts are by weight of the liquid detergent composition, unless otherwise specified. 10 It should be noted that in specifying any range of concentration, any particular upper concentration can be associated with any particular lower concentration. 15 For the avoidance of doubt the word "comprising" is intended to mean "including" but not necessarily "consisting of" or "composed of." In other words, the listed steps or options need not be exhaustive. 20 POLYANIONIC AMMONIUM SURFACTANT ("PAAS") The polyanionic ammonium surfactants suitable for use herein contain units having the structure formula: 25 WO 2005/095572 PCT/EP2005/001172 - 4 Where R is selected from hydrogen, linear or branched C1-C4 alkyl, C7-C12 Alkylaryl, C2-C12 alkylene, C3-C12 hydroxyalkylene, C4-C12 dihydroxyalkylene, C8-C12 Dialkylarylene, and where m and v are in the range of 0 to 4 and the sum of u and v are between 1 and 4. Ri is selected from hydrogen, 10 linear or branched C1-C4 alkyl, C6-C12 Alkylaryl, C2-C12 Alkylene, C3-C12 hydroxyalkylene, C4-C12 dihydroxyalkylene and C8-C12 Dialkylarylene; R2 is selected from Rl and amine oxide; 15 R' is a linking connecting the nitrogen atoms of the backbone. R' units are selected from C2-C12 alkylene, C4-C12 alkenylene, C3-C12 hydroxyalkylene wherein the hydroxyl moiety may take any position on the R' unit chain except the 20 carbon atoms directly connected to the polyamine backbone nitrogen; C4-C12 dihydroxyalkylene wherein the hydroxyl moieties may occupy any two of the carbon atoms of the R' unit chain except those carbon atoms directly connected to the backbone nitrogen. The values of a, p, and y are between 25 0 to 10 and the sum of a and β is greater than or equal to WO 2005/095572 PCT/EP2005/001172 - 5 - 1. The total number of amine groups for the present invention is between 2 to 10. S- is a conjugated base of anionic surfactant acid (S- —H+ ) 5 with a HLB number in the range of 2 to 45. S- may be expressed as R3-L- 10 Where R3 is selected from straight or branched C6-C22 alkyl, C6-C22 Alkylene, C6-C22 polyoxyalkylenealkyl, C6-C22 polyoxyalkylenatacyl, C6-C22 alkylaryl, Rosin derivatives, C6-C22 N-acylalkyl; C6-C22 a-sulfonatedtalkyl, C6-C22 hydroxyalkyl, and C6-C22 hydroxyalkylene; 15 Where L- is selected from COO- , SO3- , OSO3- r phosphoric acid, phosphorous acid, amino acids, aromatic carboxylic acid, sugar base acids derived from oxidation of monosaccharides and polysaccharides. 20 The preferred PAAS in the inventive compositions is selected from polyanionic ammonium alkyl benzene sulfonate, polyanionic ammonium alkyl sulfate, polyanionic ammonium fatty acid salt, polyanionic ammonium alkyl polyalkoxy 25 sulfate and mixtures thereof. WO 2005/095572 PCT/EP2005/001172 - 6 - The amount of PAAS employed in the inventive compositions is in the range of from 0.1% to 80%, preferably from 1% to 40%, most preferably from 5% to 20%. 5 PAAS can be prepared by reacting a polyamine with the conjugate acid of an anionic surfactant, e.g. LAS acid, fatty acid, LES acid and others. PAAS has a limited solubility in water, so PAAS granules 10 would have a limited solubility in a washing machine. The present inventors discovered that PAAS can be co-formulated with a solid acid and a carbonate-type base, so that when the granule comes into contact with water in the washing machine, a reaction between the acid and the carbonate 15 produces CO2, which facilitates the break-down of the granules, which in turn promotes the dispersion and/or dissolution of the inventive granules. It was previously believed that a polyanionic ammonium 20 surfactant (PAAS) cannot co-exist with a strong base (other than polyamine bases) because the ion-pair nature of PAAS would be broken and replaced by a strong base. Since carbonate is a strong base, it is surprising that a granule containing PAAS and carbonate can be manufactured. 25 SOLID ACID Suitable solid acids include but are not limited to citric acid, tartaric acid, aspartic acid, itaconic acid, D(+)-30 Malic acid, 2- oxoglutaric acid, dimethylmalonic acid, WO 2005/095572 PCT/EP2005/001172 - 7 - aconitic acid, succinic acid, maleic acid, glutaric acid, adipic acid. The preferred solid acids are selected from the group 5 consisting of citric acid and aspartic acid due to their non-irritancy. The most preferred solid acid is citric acid due to its low cost, availability and additional function as a builder. 10 The solid acid is included in the inventive compositions in an amount of from 0.2% to 40%, preferably from 1% to 20%, most preferably from 2% to 10%. This amount does not include any bound water. 15 CARBONATE/BICARBONATE/PERCARBONATE An ingredient selected from the group consisting of carbonate, bicarbonate, percarbonate, and mixtures thereof 20 is included in the present compositions to obtain effervescence, when carbonate/bicarbonate/percarbonate reacts with the solid acid, in an aqueous environment of the washing machine. 25 Suitable ingredients include but are not limited to the lithium, sodium and potassium salts of carbonate/bicarbonate/percarbonate. The most preferred ingredients are sodium carbonate and sodium bicarbonate due to their low cost and availability. WO 2005/095572 PCT/EP2005/001172 - 8 - The carbonate/bicarbonate/percarbonate is included in the inventive compositions in an amount of from 1 to 85%, preferably from 5 to 40%, most preferably from 10 to 25%. 5 The amount of carbonate/bicarbonate/percarbonate referred to herein does not include bound water. PROCESS OF MAKING 10 The inventive process includes contacting a polyamine and a conjugate acid of an anionic surfactant, preferably in the absence or in substantial absence of free water. The resulting PAAS may be purified, for further use in the inventive compositions. The PAAS is granulated with the 15 solid acid and the carbonate/bicarbonate/percarbonate, in the substantial absence of water. In the preferred process, the reaction product containing PAAS is used as is (without isolating the PAAS) in a further 20 step of making the granule. The absence or substantial absence of water ensures that when the reaction product, containing PAAS surfactant, is contacted with the carbonate/bicarbonate/percarbonate, the ion-pair nature of PAAS would not be broken and replaced by carbonate, 25 resulting in destruction of PAAS. Furthermore, the substantial absence of water ensures that the reaction between the solid acid and the carbonate/bicarbonate/ percarbonate does not take place, prior to the use in the washing machine. In the most preferred process, a non- 30 aqueous binder (most preferably the one that also acts as WO 2005/095572 PCT/EP2005/001172 - 9 - PAAS solubiliser) and/or a solubilizer for PAAS, is included in the reaction mixture used for making the PAAS. "Substantially non-aqueous" as used herein means at most 5 10%, preferably less than 5%, more preferably less than 1%, and optimally less than 0.5% of water. The amount of water referred to herein includes bound water. Typically, 100% of a conjugate acid of an anionic surfactant 10 is employed. The polyamine is employed in the amount of from about 10% to about 50%, preferably from 15% to 45%, most preferably from 20% to 40%, of the molar equivalent of the amount of the conjugate acid of a polyamine during the formation of PASS. Additional polyamine or other nitrogen 15 based bases may be added after the formation of PAAS. A preferred process includes first preparing a main mix by mixing propylene glycol, nonionic surfactants and anionic surfactant acids, including fatty acid. A polyamine, e.g. 20 TEPA (tetraethylenepentamine) is then added to the main mix. Mixing is continued until both acids are fully dispersed and consumed. Nonionic surfactant may be added before, during or after the addition of anionic surfactant acids. Optionally, other surfactant/ solubiliser, e.g. alkyl ether 25 sulfate salt, is then added to the main mix and the mixing is continued so as to form a homogeneous solution, which contains the PAAS and which serves as a binder. Any known granulation process may be used for preparing PAAS 30 granules. One of the preferred routes is to charge carbonate/bicarbonate/percarbonate, a solid acid and other WO 2005/095572 PCT/EP2005/00H72 - 10 - optional solid ingredients to a high shear mixer, followed by PAAS-containing binder. The ingredients are granulated at a high shear until the desired particle size is obtained. In general it takes about 0.5 to 5 minutes depending on the 5 shear and the liquid binder to solid ratio. A layering agent, e.g. zeolite, may be added to enhance the flow ability and reduce the tendency of caking. The other preferred route is to first charge 10 carbonate/bicarbonate/percarbonate, a solid acid, and optional solid ingredients to a low to medium shear mixer, such as a rolling drum granulator, a fluidized bed granulator, or a pan granulator, A layering agent, e.g. zeolite, may be added to enhance the flow ability and reduce 15 the tendency of caking. PAAS-containing binder is then sprayed-on or dripped onto the powder while the drum or pan is rotating or the bed is fluidized. OPTIONAL INGREDIENTS 20 The inventive compositions may include non-neutralized polyamine and alkyl benzene sulfonate salts and/or alkyl sulfate salts and/or fatty acid salts, in addition to the PAAS surfactant of the present invention. 25 NON-AQUEOUS OR SUBSTANTIALLY FREE OF WATER BINDER A non-aqueous or substantially free of water binder is a water-dissolvable/water dispersible liquid or a liquifiable 30 ingredient, and is generally selected from surfactants, solvents, and polymers. A liquid surfactant such as non- WO 2005/095572 PCT/EP2005/001172 - 11 - ionic surfactant is preferred. Other surfactants, such as anionic surfactants and cationic surfactants, which are solid at room temperature, may be used in conjunction with a liquid surfactant or a solvent to form a binder. A solvent, 5 such as propylene glycol, glycerol, and low molecular weight fatty alcohol and polyethylene glycol (PEG) can be used to modify the binder rheology for the ease of granulation. A polymer, such as high molecular weight PEG, may be incorporated in a molten form or pre-dissolved in a solvent 10 and used as a binder during the granulation. The manufacture of PAAS or other anionic surfactants may be used as forming of a binder in-situ via a single stage or two-stage process. For the single stage in-situ process, a 15 conjugate acid of selected anionic surfactant, used as a binder and a reactant, is added or preferably sprayed onto the solid ingredients, which includes at least one alkaline ingredient, during the granulation. The resultant anionic surfactant serves as a binder. The two-stage in-situ 20 forming anionic surfactant is suitable for forming PAAS. For the two-stage method, a conjugate acid of selected anionic surfactant is either co-added or premixed in-situ with a selected base, e.g., TEPA, prior to the addition to a granulator. The freshly formed anionic surfactant is at 25 high temperature and is mobile, thus can be easily dispersed and serves as a binder. SOLUBILIZER 30 The inventive compositions preferably include an additional solubilizer for PAAS. The solubilizer is selected from the WO 2005/095572 PCT/EP2005/001172 - 12 - group consisting of liquid surfactants, solvents (such as propylene glycol, glycerin, and ethanol), and the mixture of them, and is preferably selected from nonionic surfactants (such as C8-C18 Alkane with 5-15 EO groups) and/or alkyl 5 polyethoxy sulfate, due to their ability to help in the formation of the mixed micelles while having great solubilizing ability. In general, these solubilizers may be also be used as a binder. 10 The preferred ratio of solubilizer to PAAS is 1:10, generally in the range of from 1:10 to 10:1, by weight percentage; preferably in the range of from 1:5 to 5:1, and most preferably from 1:2 to 2:1. However, PAAS can also be dispersed or dispensed in a liquid detergent medium, 15 therefore no additional solubilizer in addition to the surfactants used in the composition is needed to obtain the cleaning performance. ADDITIONAL SURFACTANT 20 The compositions of the invention may, but do not have to contain additional surface active agents selected from the group consisting of anionic, nonionic, cationic, ampholytic and zwitterionic surfactants or mixtures thereof. The 25 preferred surfactant detergents for use in the present invention are mixtures of anionic and nonionic surfactants although it is to be understood that any surfactant may be used alone or in combination with any other surfactant or surfactants. 30 Anionic Surfactant Detergents WO 2005/095572 PCT/EP2O05/OOJ172 - 13 - Anionic surface active agents which may be used in the present invention are those surface active compounds which contain a long chain hydrocarbon hydrophobic group in their molecular structure and a hydrophilic group, i.e. water 5 solubilizing group such as carboxylate, sulfonate or sulfate group or their corresponding acid form. The anionic surface active agents include the alkali metal (e.g. sodium and potassium) and nitrogen based bases (e.g. mono-amines and polyamines) salts of water soluble higher alkyl aryl 10 sulfonates, alkyl sulfonates, alkyl sulfates and the alkyl poly ether sulfates. They may also include fatty acid or fatty acid soaps. One of the preferred groups of mono-anionic surface active agents are the alkali metal, ammonium or alkanolamine salts of higher alkyl aryl sulfonates and 15 alkali metal, ammonium or alkanolamine salts of higher alkyl sulfates or the mono-anionic polyamine salts. Preferred higher alkyl sulfates are those in which the alkyl groups contain 8 to 26 carbon atoms, preferably 12 to 22 carbon atoms and more preferably 14 to 18 carbon atoms. The alkyl 20 group in the alkyl aryl sulfonate preferably contains 8 to 16 carbon atoms and more preferably 10 to 15 carbon atoms. A particularly preferred alkyl aryl sulfonate is the sodium, potassium or ethanolamine C10 to C16 benzene sulfonate, e.g. sodium linear dodecyl benzene sulfonate. The primary and 25 secondary alkyl sulfates can be made by reacting long chain olefins with sulfites or bisulfites, e.g. sodium bisulfite. The alkyl sulfonates can also be made by reacting long chain normal paraffin hydrocarbons with sulfur dioxide and oxygen as described in U.S. Patent Nos. 2,503,280, 2,507,088, 30 3,372,188 and 3,260,741 to obtain normal or secondary higher alkyl sulfates suitable for use as surfactant detergents. WO 2005/095572 PCT/EP2005/001172 - 14 - The alkyl substituent is preferably linear, i.e. normal alkyl, however, branched chain alkyl sulfonates can be employed, although they are not as good with respect to biodegradability. The alkane, i.e. alkyl, substituent may 5 be terminally sulfonated or may be joined, for example, to the 2-carbon atom of the chain, i.e. may be a secondary sulfonate. It is understood in the art that the substituent may be joined to any carbon on the alkyl chain. The higher alkyl sulfonates can be used as the alkali metal salts, such 10 as sodium and potassium. The preferred salts are the sodium salts. The preferred alkyl sulfonates are the Cio to Ci8 primary normal alkyl sodium and potassium sulfonates, with the Cio to C15 primary normal alkyl sulfonate salt being more preferred. 15 Mixtures of higher alkyl benzene sulfonates and higher alkyl sulfates can be used as well as mixtures of higher alkyl benzene sulfonates and higher alkyl polyether sulfates. 20 The alkali metal or ethanolamine sulfate can be used in admixture with the alkyl benzene sulfonate in an amount of 0 to 70%, preferably 5 to 50% by weight. The higher alkyl polyethoxy sulfates used in accordance with 25 the present invention can be normal or branched chain alky and contain lower alkoxy groups which can contain two or three carbon atoms. The normal higher alkyl polyether sulfates are preferred in that they have a higher degree of biodegradability than the branched chain alkyl and the lower 30 poly alkoxy groups are preferably ethoxy groups. WO 2005/095572 PCT/EP2005/001172 - 15 - The preferred higher alkyl polyethoxy sulfates used in accordance with the present invention are represented by the formula: 5 R1-O(CH2CH2O)P-SO3M where R1 is C8 to C20 alkyl, preferably C10 to C18 and more preferably C12 to C15; p is 1 to 8, preferably 2 to 6, and more preferably 2 to 4; and M is an alkali metal, such as 10 sodium and potassium, an ammonium cation or polyamine. The sodium and potassium salts, and polyaimines are preferred. A preferred higher alkyl poly ethoxylated sulfate is the sodium salt of a triethoxy C32 to C15 alcohol sulfate having 15 the formula: C12-15-O-(CH2CH2O)3-SO3Na Examples of suitable alkyl ethoxy sulfates that can be used 20 in accordance with the present invention are C12-15 normal or primary alkyl triethoxy sulfate, sodium salt; n-decyl diethoxy sulfate, sodium salt; C12 primary alkyl diethoxy sulfate, ammonium salt; C12 primary alkyl triethoxy sulfate, sodium salt; C15 primary alkyl tetraethoxy sulfate, sodium 25 salt; mixed C14-15 normal primary alkyl mixed tri- and tetraethoxy sulfate, sodium salt; stearyl pentaethoxy WO 2005/095572 PCT/EP2005/001172 - 16 - sulfate, sodium salt; and mixed C10-18 normal primary alkyl triethoxy sulfate, potassium salt. The normal alkyl ethoxy sulfates are readily biodegradable 5 and are preferred. The alkyl poly-lower alkoxy sulfates can be used in mixtures with each other and/or in mixtures with the above discussed higher alkyl benzene, sulfonates, or alkyl sulfates. 10 The alkali metal higher alkyl poly ethoxy sulfate can be used with the alkyl benzene sulfonate and/or with an alkyl sulfate, in an amount of 0 to 70%, preferably 5 to 50% and more preferably 5 to 20% by weight of entire composition. 15 Nonionic Surfactant Nonionic surfactants which can be used with the invention, alone or in combination with other surfactants are described below. 20 As is well known, the nonionic surfactants are characterized by the presence of a hydrophobic group and an organic hydrophilic group and are typically produced by the condensation of an organic aliphatic or alkyl aromatic 25 hydrophobic compound with ethylene oxide (hydrophilic in nature). Typical suitable nonionic surfactants are those disclosed in U.S. Patent Nos. 4,316,812 and 3,630,929. Usually, the nonionic surfactants are polyalkoxylated lipophiles wherein the desired hydrophile-lipophile balance 30 is obtained from addition of a hydrophilic poly-alkoxy group to a lipophilic moiety. A preferred class of nonionic WO 2005/095572 PCT/EP2005/OO1172 - 17 - detergent is the alkoxylated alkanols wherein the alkanol is of 9 to 20 carbon atoms and wherein the number of moles of alkylene oxide (of 2 or 3 carbon atoms) is from 3 to 20. Of such materials it is preferred to employ those wherein the 5 alkanol is a fatty alcohol of 9 to 11 or 12 to 15 carbon atoms and which contain from 5 to 9 or 5 to 12 alkoxy groups per mole. Also preferred is paraffin - based alcohol (e.g. nonionics from Huntsman or Sassol). 10 Exemplary of such compounds are those wherein the alkanol is of 10 to 15 carbon atoms and which contain about 5 to 12 ® ethylene oxide groups per mole, e.g. Neodol 25-9 and ® Neodol 23-6.5, which products are made by Shell Chemical Company, Inc. The former is a condensation product of a 15 mixture of higher fatty alcohols averaging about 12 to 15 carbon atoms, with about 9 moles of ethylene oxide and the latter is a corresponding mixture wherein the carbon atoms content of the higher fatty alcohol is 12 to 13 and the number of ethylene oxide groups present averages about 6.5. 20 The higher alcohols are primary alkanols. Another subclass of alkoxylated surfactants which can be used contain a precise alkyl chain length rather than an alkyl chain distribution of the alkoxylated surfactants 25 described above. Typically, these are referred to as narrow range alkoxylates. Examples of these include the Neodol-1(R) series of surfactants manufactured by Shell Chemical Company. WO 2005/095572 PCT/EP2005/001172 - 18 - Other useful nonionics are represented by the commercially well known class of nonionics sold under the trademark Plurafac® by BASF. The Plurafacs® are the reaction products of a higher linear alcohol and a mixture of ethylene and 5 propylene oxides, containing a mixed chain of ethylene oxide and propylene oxide, terminated by a hydroxyl group. Examples include C13-C15 fatty alcohol condensed with 6 moles ethylene oxide and 3 moles propylene oxide, C13-C15 fatty alcohol condensed with 7 moles propylene oxide and 4 moles 10 ethylene oxide, C13-C15 fatty alcohol condensed with 5 moles propylene oxide and 10 moles ethylene oxide or mixtures of any of the above. Another group of liquid nonionics are commercially available 15 from Shell Chemical Company, Inc. under the Dobanol or Neodol trademark: Dobanol 91-5 is an ethoxylated C9-C3.1 fatty alcohol with an average of 5 moles ethylene oxide and Dobanol 25-7 is an ethoxylated C12-C15 fatty alcohol with an average of 7 moles ethylene oxide per mole of fatty alcohol. 20 In the compositions of this invention, preferred nonionic surfactants include the C12-C15 primary fatty alcohols with relatively narrow contents of ethylene oxide in the range of from about 6 to 9 moles, and the C9 to C11 fatty alcohols 25 ethoxylated with about 5-6 moles ethylene oxide. Another class of nonionic surfactants which can be used in accordance with this invention are glycoside surfactants. WO 2005/095572 PCT/EP2005/00H72 - 19 - Glycoside surfactants suitable for use in accordance with the present invention include those of the formula: RO-(R2O)y- (Z)x 5 wherein R is a monovalent organic radical containing from about 6 to about 30 (preferably from about 8 to about 18) 2 carbon atoms; R is a divalent hydrocarbon radical containing from about 2 to 4 carbons atoms; O is an oxygen 10 atom; y is a number which can have an average value of from 0 to about 12 but which is most preferably zero; Z is a moiety derived from a reducing saccharide containing 5 or 6 carbon atoms; and x is a number having an average value of from 1 to about 10 (preferably from about 1 1/2 to about 15 10) . A particularly preferred group of glycoside surfactants for use in the practice of this invention includes those of the formula above in which R is a monovalent organic radical 20 inear or branched) containing from about 6 to about 18 (especially from about 8 to about 18) carbon atoms; y is zero; z is glucose or a moiety derived therefrom; x is a number having an average value of from 1 to about 4 (preferably from about 1 1/2 to 4). 25 Nonionic surfactants which may be used include polyhydroxy amides as discussed in U.S. Patent No. 5,312,954 to Letton et al. and aldobionamides such as disclosed in U.S. Patent No. 5,389,279 to Au et al. WO 2005/095572 PCT/EP2005/001172 - 20 - Generally, nonionics would comprise 0-75% by wt preferably 5 to 50%, more preferably 5 to 25% by wt. of the composition. 5 Mixtures of two or more of the nonionic surfactants can be used. Cationic Surfactants 10 Many cationic surfactants are known in the art, and almost any cationic surfactant having at least one long chain alkyl group of about 10 to 24 carbon atoms is suitable in the present invention. Such compounds are described in "Cationic Surfactants", Jungermann, 1970. 15 Specific cationic surfactants which can be used as surfactants in the subject invention are described in detail in U.S. Patent No. 4,497,718. 20 As' with the nonionic and anionic surfactants, the compositions of the invention may use cationic surfactants alone or in combination with any of the other surfactants known in the art. Of course, the compositions may contain no cationic surfactants at all. WO 2005/095572 PCT/EP2005/001172 - 21 - Amphoteric Surfactants Ampholytic synthetic surfactants can be broadly described as derivatives of aliphatic or aliphatic derivatives of 5 heterocyclic secondary and tertiary amines in which the aliphatic radical may be straight chain or branched and wherein one of the aliphatic substituents contains from about 8 to 18 carbon atoms and at least one contains an anionic water-soluble group, e.g. carboxylate, sulfonate, 10 sulfate. Examples of compounds falling within this definition are sodium 3-(dodecylamino)propionate, sodium 3-(dodecylamino) propane-1-sulfonate, sodium 2-(dodecylamino)ethyl sulfate, sodium 2- (dimethylamino) octadecanoate, disodium 3-(N-carboxymethyldodecylamino) 15 propane 1-sulfonate, disodium octadecyl-imminodiacetate, sodium l-carboxymethyl-2- undecylimidazole, and sodium N,N-bis (2-hydroxyethyl)-2-sulfato-3- dodecoxypropylamine. Sodium 3- (dodecylamino) propane-1-sulfonate is preferred. 20 Zwitterionic surfactants can be broadly described as derivatives of secondary and tertiary amines, derivatives of heterocyclic secondary and tertiary amines, or derivatives of quaternary ammonium, quaternary phosphonium or tertiary sulfonium compounds. The cationic atom in the quaternary 25 compound can be part of a heterocyclic ring. In all of these compounds there is at least one aliphatic group, straight chain or branched, containing from about 3 to 18 carbon atoms and at least one aliphatic substituent containing an anionic water-solubilizing group, e.g., 30 carboxy, sulfonate, sulfate, phosphate, or phosphonate. WO 2005/095572 PCT/EP2005/001172 - 22 - Specific examples of zwitterionic surfactants which may be used are set forth in U.S. Patent No. 4,062,647. The amount of additional surfactant used may vary from 1 to 5 85% by weight, preferably 10 to 50% by weight. As noted the preferred surfactant systems of the invention are mixtures of anionic and nonionic surfactants. 10 Preferably, the nonionic should comprise, as a percentage of an anionic/nonionic system, at least 20%, more preferably at least 25%, up to about 75% of the total surfactant system. A particularly preferred surfactant system comprises anionic: nonionic in a ratio of 3:1. 15 Builders/Electrolytes Builders which can be used according to this invention include conventional alkaline detergency builders, inorganic 20 or organic, which should be used at levels from about 0.1% to about 20.0% by weight of the composition, preferably from 1.0% to about 10.0% by weight, more preferably 2% to 5% by weight. 25 As electrolyte may be used any water-soluble salt. Electrolyte may also be a detergency builder, such as the inorganic builder sodium tripolyphosphate, or it may be a non-functional electrolyte such as sodium sulphate or chloride.

Aluminosilicates may also be used as a layering agent to enhance the granule flowability. 5 Alkalinity buffers which may be added to the compositions of the invention include monoethanolamine, triethanolamine, borax and the like. Inorganic buffers may be added in substantially free of free water form. 10 Enzymes One or more enzymes as described in detail below, may be used in the compositions of the invention. 15 If a lipase is used, the lipolytic enzyme may be either a fungal lipase producible by Humicola_lanuginosa and Thermomyces lanuginosus, or a bacterial lipase which show a positive immunological cross-reaction with the antibody of 20 the lipase produced by the microorganism Chromobacter viscosum var. lipolyticum NRRL B-3673. An example of a fungal lipase as defined above is the lipase ex Humicola lanuginosa, available from Amano under the 25 tradename Amano CE; the lipase ex Humicola lanuginosa as described in the aforesaid European Patent Application 0,258,068 (NOVO), as well as the lipase obtained by cloning the gene from Humicola lanuginosa and expressing this gene in Aspergillus oryzae, commercially available from Novozymes 30 under the tradename "Lipolase". This lipolase is a preferred lipase for use in the present invention. WO 2005/095572 PCT/EP2005/001172 - 26 - While various specific lipase enzymes have been described above, it is to be understood that any lipase which can confer the desired lipolytic activity to the composition may be used and the invention is not intended to be limited in 5 any way by specific choice of lipase enzyme. The lipases of this embodiment of the invention are included in the liquid detergent composition in such an amount that the final composition has a lipolytic enzyme activity of 10 from 100 to 0.005 LU/ml in the wash cycle, preferably 25 to 0.05 LU/ml when the formulation is dosed at a level of about .1-10, more preferably .5-7, most preferably 1-2 g/liter. Naturally, mixtures of the above lipases can be used. The 15 lipases can be used in their non-purified form or in a purified form, e.g. purified with the aid of well-known absorption methods, such as phenyl sepharose absorption techniques. 20 If a protease is used, the proteolytic enzyme can be of vegetable, animal or microorganism origin. Preferably, it is of the latter origin, which includes yeasts, fungi, molds and bacteria. Particularly preferred are bacterial subtilisin type proteases, obtained from e.g. particular 25 strains of B. subtilis and B licheniformis. Examples of suitable commercially available proteases are Alcalase® , Savmase® , Esperase® , all of Novozymes; Maxatase® and Maxacal® of Gist-Brocades; Kazusase® of Showa Denko. The amount of proteolytic enzyme, included in the composition, 30 ranges from 0.05-50,000 GU/mg. preferably 0.1 to 50 GU/mg, WO 2005/095572 PCT/EP2005/001172 - 27 - based on the final composition. Naturally, mixtures of different proteolytic enzymes may be used. While various specific enzymes have been described above, it 5 is to be understood that any protease which can confer the desired proteolytic activity to the composition may be used and this embodiment of the invention is not limited in any way be specific choice of proteolytic enzyme. 10 In addition to lipases or proteases, it is to be understood that other enzymes such as cellulases, oxidases, amylases, peroxidases and the like which are well known in the art may also be used with the composition of the invention. The enzymes may be used together with co-factors required to 15 promote enzyme activity, i.e., they may be used in enzyme systems, if required. It should also be understood that enzymes having mutations at various positions (e.g., enzymes engineered for performance and/or stability enhancement) are also contemplated by the invention. 20 The enzyme stabilization system may be included, although by virtue of being solid, the inventive compositions do not actually require enzyme stabilization. Enzyme stabilization systems include comprise propylene glycol and/or short chain 25 carboxylic acids. One preferred stabilization system is a polyol in combination with boric acid. Preferably, the weight ratio of polyol to boric acid added is at least 1, more preferably 30 at least about 1.3. WO 2005/095572 PCT/EP2005/001172 - 28 - Clay Other materials such as clays, particularly of the water-insoluble types, may be useful adjuncts in 5 compositions of this invention. Particularly useful is bentonite. This material is primarily montmorillonite which is a hydrated aluminum silicate in which about l/6th of the aluminum atoms may be replaced by magnesium atoms and with which varying amounts of hydrogen, sodium, potassium, 10 calcium, etc. may be loosely combined. The bentonite in its. more purified form (i.e. free from any grit, sand, etc.) suitable for detergents contains at least 50% montmorillonite and thus its cation exchange capacity is at least about 50 to 75 meq per l00g of bentonite. 15 Particularly preferred bentonites are the Wyoming or Western U.S. bentonites which have been sold as Thixo-jels 1, 2, 3 and 4 by Georgia Kaolin Co. These bentonites are known to soften textiles as described in British Patent No. 401, 413 to Marriott and British Patent No. 461,221 to Marriott and 20 Guam. Fluorescent Whitening Agent ("FWA") The inventive compositions preferably include from 0.01% to 25 2.0%, more preferably from 0.05% to 1.0%, most preferably from 0.05% to 0.5% of a fluorescer.

MINOR INGREDIENTS 10 In addition, various other detergent additives or adjuvants may be present in the detergent product to give it additional desired properties, either of functional or aesthetic nature. 15 For instance, there also may be included in the formulation, minor amounts of soil suspending or anti-redeposit ion agents, e.g. polyvinyl alcohol, fatty amides, sodium 20 Carboxymethyl cellulose, hydroxy-propyl methyl cellulose. A preferred anti-redeposit ion agent is sodium carboxyl methyl cellulose having a 2:1 ratio of CM/MC which is sold under the tradename Relation DM 4050. 25 Anti-foam agents, e.g. silicon compounds, such as Silicane® L 7 604, can also be added in small effective amounts, although it should be noted that the inventive compositions are low-foaming. 30 Bactericides, e.g. tetrachlorosalicylanilide and hexachlorophene, fungicides, dyes, pigments (water dispersible), preservatives, e.g. formalin, ultraviolet absorbers, anti-yellowing agents, such as sodium WO 2005/095572 PCT/EP2005/001172 - 30 - carboxymethyl cellulose, pH modifiers and pH buffers, color safe bleaches, perfume and dyes and bluing agents such as Iragon Blue L2D, Detergent Blue 472/572 and ultramarine blue can be used. 5 Also, additional soil release polymers and cationic softening agents may be used. Preferably, the detergent composition is a colored 10 composition packaged in the transparent/translucent ("see-through") container. METHOD OF USING COMPOSITIONS 15 In use, the indicated quantity of the composition (generally in the range from 50 to 200 ml) depending on the size of the laundry load, the size and type of the washing machine, is added to the washing machine which also contains water and the soiled laundry. The inventive laundry compositions are 20 particularly suited for use with front-loading washing machine, due to the ability of the inventive compositions to deliver high performance with low foaming - front-loading machines require low foaming compositions. 25 The following specific examples further illustrate the invention, but the invention is not limited thereto. The abbreviations in the Examples denote the following: TEPA: Tetraethylenepentamine 30 NA-LAS: Sodium alkylbenzenesufonate LAS acid: alkylbenzenesulfonic acid WO 2005/095572 PCT/EP2005/001172 - 31 - Na~LES: Sodium alkylpolyethoxysulfate Neodol® 25-7: 7-EO C12-C15 fatty alcohol Neodol® 25-9: 9-EO C12-C15 fatty alcohol 5 EXAMPLE 1 AND COMPARATIVE EXAMPLE 1A This example demonstrates one of the differences in one of the physical properties (water solubility) between PAAS surfactant employed in the present invention and TEPA and 10 Na-LAS mixtures in the prior art. In Example 1, when LAS acid was neutralized with a polyamine (i.e., TEPA), it formed PAAS. As PAAS began forming, the solution became hazy. Upon further addition of the LAS 15 acid, the hazy solution became a dispersion. Upon standing for hours, the dispersion formed a layer of sediment at the bottom of the beaker. Even a very diluted formulation (such as below 0.1%) was hazy. 20 TEPA has multiple nitrogen sites. Without wishing to be limited by this theory, it is believed that upon continued addition of LAS acid, the PAAS formed different compounds and gave different assemblies. At the beginning of addition of LAS acid, only single nitrogen atom was protonated, 25 forming a micellar solution, which is a clear solution.. Upon the addition of more LAS acid, multiple nitrogen atoms were protonated. PAAS eventually precipitated from the solution because of the lack of ionization of the PAAS due to the strong ion-bond formation between LAS and TEPA and 30 internal hydrophobic interaction. WO 2005/095572 PCT/EP2005/001172 - 32 - In Example 1A the behaviour was completely different: Na-LAS solution with added TEPA gave a clear solution throughout the titration of LAS acid and remained clear upon addition of TEPA. 5 The solution was clear at the all time over the entire pH range, leading to the conclusion that Na-LAS was fully ionized or disassociated. The clarity of solution did not change upon the addition of TEPA for the pH from 2.5 to 10 10.0. It indicates that the addition of TEPA does not convert Na-LAS to PAAS. This means that PAAS formed much stronger assemblies than Na-LAS and TEPA. physical mixture. PAAS could not be 15 dispersed in single molecular state but dispersed as aggregates. The results that were obtained for Examples 1 and 1A are summarized in Tables 1 and 1A respectively. 20 WO 2005/095572 PCT7EP2005/001172 - 33 -TABLE 1 Ingredient Wt (g) Observations Water 94.0 Clear TEPA 2.0 Clear LAS acid 2.6 Hazy solution, pH 10.50 6.0 Hazy dispersion, pH 9.95 7.4 Dispersion, pH 9.60 9.0 Dispersion, pH 9.03, after standing hours at room temperature precipitate was formed on the bottom of the beaker. TABLE 1A 5 Ingredient Wt (g) Results Water 96.00 NaOH, 50% 1.60 LAS acid 6.38 pH=2.5; a clear solution TEPA 0.11 pH=7.78; a clear solution 0.15 pH=10.0; a clear solution EXAMPLE 2 Example 2 demonstrates that PAAS surfactant is a strongly 10 bonded molecule, which does not exchange counterions with Other salts. Sodium xylenesulfonate was added to an aqueous PAAS dispersion to attempt to solubilize PAAS by ion-exchange and/or hydrotrope mechanism. The results that were obtained are summarized in Table 2. 15 WO 2005/095572 PCT/EP2005/001172 - 34 -TABLE 2 Ingredient Wt (g) Observations PAAS preparation Water 98.0 LAS acid 6.38 TEPA 2.0 PAAS formed (7.8% concentration). Looked as milky dispersion. After standing several days at room temperature, precipitate was formed. Ingredient Wt (g) Observations PAAS (7.8%) 20.0 Water 300.0 Sodiumxylenesulfonate(40%) 20.5 still hazy and eventually TEPA-LAS precipitates are found in the solution The concentration of PAAS in the above formulation was 5 0.46%. The molar ratio of sodium xylenesulfonate to-PAAS was 21:1. There was enough Na xylenesulfonate for PAAS to change counter ions from TEPA to Na. However, PAAS did not ionize 10 and remained as a dispersion. It indicated that the bond between polyamine and conjugated acid of PAAS is very strong. WO 2005/095572 PCT/EP2005/001172 - 35 -EXAMPLE 3 Example 1 was repeated, except that fatty acid was used in place of LAS acid. 5 A phenomenon similar to that of Example 1 (formation of a dispersion insoluble in water) was observed for the product of fatty acid and polyamine. The results that were obtained are summarized in Table 3. 10 TABLE 3 Ingredient Wt (g) Observations Water 92.0 Coco acid 10.35 TEPA 2.6 Hazy solution 3.15 Hazy dispersion, and after standing, a phase separation occurred (precipitates formed in the bottom). 15 EXAMPLE 4 The PAAS granules were prepared by charging sodium bicarbonate, citric acid and the half of the amount of zeolite into a granulator, Black and Decker Model SC400 2- 20 speed super chopper. This was followed by the addition of LAS acid and TEPA mixture, which was at the initial stage of the reaction and still maintained its mobility. Right after the addition of LAS acid and TEPA, the granulator was run at high speed for 90 seconds to form granules. Neodol 25-7 was WO 2005/095572 PCT/EP2005/001172 - 36 - added followed by 15 seconds high speed mixing. Finally, the layering agent (the remaining zeolite), was added, followed by 15 seconds of low speed mixing. The granules were passed through 1.5mm screen. 5 Ingredients % Neodol 25-7 7.1 LAS acid, 95.5% 5.5 TEPA 1.7 Citric Acid, monohydrated 34.1 Sodium Bicarbonate 41.1 Zeolite 10.2 Misc. To 100 The resulting granules were tested for disintegratability and dissolution by adding 0.5g of granules to 1-liter cold 10 water (170C). The granules first sunk to the bottom and then effervesced and floated to the top. In less than 90 seconds the granules were fully disintegrated and dissolved, even without agitation. 15 COMPARATIVE EXAMPLE 5 20 This example demonstrates that the inventive granule must contain all three ingredients: the PAAS, the acid, and the base. If the ingredients reside in separate granules, PAAS solubility is not improved. WO 2005/095572 PCT/EP2005/001172 - 37 - LAS acid and TEPA were mixed in-situ and forced through a nozzle to form PAAS granules with size about 1500 microns. All the rest ingredients were charged to a granulator and mixed at the high speed for 45 seconds. The resulting 5 separate granules then blended with the PAAS granules using a V-shape blender. After 10 minutes, the PAAS granules still not fully dissolved via the test method described in Example 4. It is believed that although there was still effervescence, the generation of CO2 did not break-up PAAS 10 granules, thus the dissolution rate was very low. EXAMPLE 6 The PAAS granules of Example 6 were prepared by charging 90% 15 of zeolite and TEPA into a granulator and mixed for 10 seconds at high speed. This was followed by charging LAS acid and mixed for 25 seconds to promote the formation of PAAS at the surface of zeolite particles, without forming granules. Sodium carbonate, sodium bicarbonate and citric 20 acid were then added and mixed for 60 seconds to form granules. Finally, the rest of the zeolite was added and mixed at low speed for 10 seconds as a layering agent. The granules were passed through 1.5 mm screen. Ingredients % LAS acid, 95.5% 7.8 TEPA 6.1 Citric Acid, monohydrated 25.9 Sodium Bicarbonate 23.1 Sodium carbonate 5.0 Zeolite 30.2 Miscellaneous To 100 WO 2005/095572 PCT/EP2005/001172 - 38 - The granules were fully dissolved in less than 90 seconds by the test method described in Example 4.
