FORM - 2 THE PATENTS ACT, 1970 (39 of 1970) & The Patents Rules, 2003 COMPLETE SPECIFICATION (See Section 10 and Rule 13) LAUNDRY TREATMENT COMPOSITIONS 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, Murnbai -400 020, Maharashtra, India The following specification particularly describes the invention and the manner in which it is to be performed WO 2005/118761 PCT/EP2005/005121 LAUNDRY TREATMENT COMPOSITIONS Technical Field 5 The present invention relates to compositions comprising modified polysaccharides and sugar polyesters. These compositions are suitable, for example, for use as laundry treatment compositions or as components thereof. Laundry treatment compositions containing compositions according to 10 the invention, provide softening benefits to fabric. The invention further relates to a method of depositing a sugar polyester from solution or dispersion, onto a substrate by means of such a composition. 15 Background of the Invention Compositions which are capable of imparting softening to substrates such as fabric, hair and skin are well known in the art. To date, silicones and related compounds are 20 widely used as softening agents. However, despite its excellent softening properties, silicone has a number of inherent disadvantages associated with it, hence the need exists for new softening compounds 25 that don't have the disadvantages of silicones. In the context of laundry products, the low biodegradable nature of silicone is a notable disadvantage and one which increases in significance as environmental legislation 30 continues to get tougher. Therefore, to find alternatives to silicone which are more biodegradable is a widely sought WO 2005/118761 PCT/EP2005/005121 - 2 - after goal. Another problem often encountered when using silicones as softeners in laundry is that although they increase the soft feel of a fabric they decrease the fabric's absorbency. A decrease in the absorbency 5 properties of a fabric means that its ability to take up water decreases - this is particularly problematic for towels and is strongly disliked by the consumer. Further, cost reduction is an ever present goal across the industry and cheaper alternatives to silicones as softeners are thus 10 sought after. The improvement of these aspects without a consequential loss in softening capability is clearly desirable. 15 Prior Art WO-A-00/18861 provides a water-soluble or water-dispersible polysaccharide which comprises: a deposition enhancing part (the polymeric backbone - which in the case of cellulose 20 shows self-recognition properties) and a benefit agent group, which may be a softening agent, attached to the. deposition enhancing part by a hydrolytically stable bond. During a treatment process the material undergoes a chemical change which does not involve the hydrolytically stable bond 25 but by which the affinity of the material onto the substrate is increased. A preferred material, is cellulose mono acetate (CMA). This molecule has an affinity for cotton due to the self-recognition properties of cellulose and is soluble due to the presence of acetate groups. The acetate 30 groups hydrolyse in aqueous solution causing the deposited cellulose to remain on a cellulosic substrate. Manufacture WO 2005/118761 PCT/EP2005/005121 - 3 - of CMA involves excessive esterification of the -OH groups of the cellulose and then hydrolysis of some of the esters to attain the desired degree of esterification. 5 Our UK patent application no. GB 0121148 discloses a substituted b1-4 linked polysaccharide such as cellulose mono-acetate with one or more independently selected silicone chains covalently attached to it as the benefit agent. 10 While the molecules of GB 0121148 are relatively expensive, it has been found that the covalently-linked silicone chains may be used to emulsify droplets of a further portion of silicone to enhance the deposition of that material. 15 Our UK patent application no GB 0123380 discloses a laundry treatment composition comprising a composition similar to that of GB 0121148 in combination with a non-covalently bonded silicone which is, for example, emulsified in the 20 same composition. This enables relatively large quantities of silicone to be deposited without an excessive on-cost for the formulator. Our co-pending patent application, GB 0313900, discloses a 25 non-hydrolysable polysaccharide, with a textile benefit species bonded thereto by a hydrolytically stable bond. A further benefit species may also be present. Silicone is both preferred and exemplified as both benefit species. Despite the above-mentioned advances, the need remains to 30 further improve upon such deposition systems. It is advantageous to reduce cost, improve the biodegradability of 07-2006 EP200500121 34367 (C) WO (Amended 12 July 06) 4 - 10 15 20 the material and improve absorbency without compromising the softening effect.. It has now surprisingly been found that compositions 5 comprising a water-soluble or dispersible polysaccharide having a hydrophobic agent bonded thereto by a hydrolytically stable bond and a sugar polyester give benefits of improved biodegradability, lower cost and less hydrophobing without any loss of softening benefit.

The invention further provides emulsions comprising compositions according to the first aspect as a dispersed phase. Ideally, these emulsions may be dried or otherwise 15 encapsulated, to provide a dispersible form of the compositions of the invention. The dispersible form can comprise an adjunct, preferably a granulate, suitable for inclusion in a laundry composition. 20 Fully formulated laundry compositions according to the present invention preferably contain a surfactant (which may be nonionic, anionic, cationic, or a mixture of some or all thereof). Preferably the surfactant is a detersive surfactant, more preferably an anionic or nonionic surfactant 25 or a mixture thereof. Typically, the level of the modified polysaccharide (i.e. the polysaccharide with hydrophobic agent bonded thereto) and SPE in a fully formulated composition will be from 0.001 to 25 30 percent (%) by weight of the fully formulated composition. .07-2006. EP200500512 G4 3 67- (C) WG (Amended 12 July 06) Detailed Description of the Invention As set out above, the composition of the present invention comprises a polysaccharide which is water-soluble or water 5 dispersible in nature and which has a' hydrophobic agent, "which is attached to the polysaccharide by a hydrolytically stable, bond,/and which in a preferred embodiment is a silicone. The composition further comprises a sugar polyester (SPE). The SPE may or may not be chemically 10 bonded to the polysaccharide. Furthermore, some of the SPE may be- chemically bonded to the polysaccharide,, whilst some is not. The invention will be described below, in respect of various 15 embodiments.' For the sake of" clarity, the term- "modified polysaccharide" as used herein means the polysaccharide...having the hydrophobic, agent bonded thereto. 2 0 2 5 The polysaccharide The water-soluble or dispersable polysaccharide is a b-i,4-1 inked polysaccharide having an affinity for cellulose. The polysaccharide may be hydrolysable or non-hydrolysable By hydrolysable polysaccharide is meant' that the polysaccharide- contains a deposition enhancing" group which 30 undergoes a chemical change under conditions (including AMENDED SHFFT WO 2005/118761 PCT/EP2005/005121 - 7 - temperature) of use to increase the affinity of the polysaccharide for a substrate. In those embodiments of the invention intended for aqueous treatment of substrates, such as in a wash liquor, these conditions can include elevated Ph 5 and/or temperatures above ambient. By non-hydrolysable polysaccharide is meant that the polysaccharide does not contain such a deposition enhancing group. By an increase in the affinity of the polysaccharide for a 10 substrate (such as a textile fabric) upon a chemical change, is meant that at some time during the treatment process, the amount of material that has been deposited is greater when the chemical change is occurring or has occurred, compared to when the chemical change has not occurred and is not 15 occurring, or is occurring more slowly, the comparison being made with all conditions being equal except for that change in the conditions which is necessary to affect the rate of chemical change. 20 By water-soluble, as used herein, is meant is that the material forms an isotropic solution on addition to water or another aqueous solution. By water-dispersible, as used herein, is meant is that the 25 material forms a finely divided suspension on addition to water or another aqueous solution. Deposition onto a substrate includes deposition by adsorption, co-crystallisation, entrapment and/or adhesion. 30 WO 2005/118761 PCT/EP2005/005121 - 8 - The polysaccharide may be straight or branched. Many naturally occurring polysaccharides have at least some degree of branching, or at any rate at least some saccharide rings are in the form of pendant side groups on a main 5 polysaccharide backbone. A polysaccharide comprises a plurality of saccharide rings which have pendant hydroxyl groups. In the preferred polysaccharides of the present invention, at least some of 10 these hydroxyl groups are independently substituted by, or replaced with, one or more other substituents, at least one being a hydrophobic agent. In our preferred class of materials the hydrophobic agent is a silicone chain. The "average degree of substitution" for a given class of 15 substituent means the average number of substituents of that class per saccharide ring for the totality of polysaccharide molecules in the sample and is determined for all saccharide rings. 20 Deposition enhancing groups By deposition enhancing group is meant a group which undergoes a chemical change under conditions of use to increase the affinity of the polysaccharide for a substrate. 25 The deposition enhancing group is attached to the polysaccharide agent group by means of a chemical bond. The average degree of substitution of these pendant groups which undergo the chemical change is preferably from 0.1 to 30 3 (e.g. from 0.3 to 3), more preferably from 0.1 to 1 (e.g. from 0.3 to 1). WO 2005/118761 PCT/EP2005/005121 - 9 - The chemical change which causes the increased substrate affinity is preferably caused by hydrolysis, perhydrolysis or bond-cleavage, optionally catalysed by an enzyme or another catalyst. Hydrolysis of substituent ester-linked 5 groups is typical. By ester linkage is meant that the hydrogen of an -OH group, present on the polysaccharide backbone, has been replaced by a substituent such as R'-CO-, R'SO2- etc to form a 10 carboxylic acid ester, sulphonic acid ester (as appropriate) etc together with the remnant oxygen attached to the saccharide ring. In some cases, the group R' may for example contain a heteroatom, e.g. as an -NH- group attached to the carbonyl, sulphonyl etc group, so that the linkage as 15 a whole could be regarded as a urethane etc linkage. However, the term ester linkage is still to be construed as encompassing these structures. Thus, the deposition enhancing groups have the general formula (I) :- 20 -OR where the oxygen is the remnant oxygen from the -OH group attached to the saccharide ring, and 25 where the R groups are independently selected from groups of formulae: - WO 2005/118761 PCT/EP2005/005121 5 wherein each R is independently selected from C1-20 (preferably C1-6) alkyl, C2-20 (preferably C2-6) alkenyl (e.g. vinyl) and C5-7 aryl (e.g. phenyl) any of which is optionally substituted by one or more substituents independently 10 selected from C1-4 alkyl, C1-12 (preferably C1-4) alkoxy, hydroxyl, vinyl and phenyl groups; each R2 is independently selected from hydrogen and groups R1 as hereinbefore defined; 15 R3 is a bond or is selected from C1-4 alkylene, C2-4 alkenylene and C5_7 arylene (e.g. phenylene) groups, the carbon atoms in any of these being optionally substituted by one or more substituents independently selected from C3.-12 (preferably Ci_ 20 4) alkoxy, vinyl, hydroxyl, halo and amine groups; WO 2005/118761 PCT/EP2005/005121 - 11 - each R4 is independently selected from hydrogen, counter cations such as alkali metal (preferably Na) or CCa or Mg, and groups R1 as hereinbefore defined; and 5 groups R which together with the oxygen atom forming the linkage to the respective saccharide ring forms an ester or hemi-ester group of a tricarboxylic- or higher polycarboxylic- or other complex acid such as citric acid, an amino acid, a synthetic amino acid analogue or a protein; 10 any remaining R groups being selected from hydrogen and other substituents. Some of the R groups may optionally have one or more 15 structures, for example as hereinbefore described. For example, one or more R groups may simply be hydrogen or an alkyl group. Preferred groups which undergo the chemical change may for 20 example be independently selected from one or more of acetate, propanoate, trifluroacetate, 2-(2-hydroxy-l- oxopropoxy) propanoate, lactate, glycolate, pyruvate, crotonate, isovalerate cinnamate, formate, salicylate, carbamate, methylcarbamate, benzoate, gluconate, 25 methanesulphonate, toluene, sulphonate, groups and hemiester groups of fumaric, malonic, itaconic, oxalic, maleic, succinic, tartaric, aspartic, glutamic, and malic acids. Particularly preferred such groups are the monoacetate, 30 hemisuccinate, and 2-(2-hydroxy-l-oxopropoxy)propanoate. The term "monoacetate" is used herein to denote those WO 2005/118761 PCT/EP2005/005121 - 12 - acetates with the degree of substitution of less than 1 and greater than 0.4 on a cellulose or other b-1,4 polysaccharide backbone. 5 Cellulose esters of hydroxyacids can be obtained using the acid anhydride in acetic acid solution at 20-30°C and in any case below 50°C. When the product has dissolved the liquid is poured into water (b.p. 316,160). Tri-esters can be converted to secondary products as with the triacetate. 10 Glycollic and lactic ester are most common. Cellulose glycollate may also be obtained from cellulose chloracetate (GB-A-320 842) by treating 100 parts with 32 parts of NaOH in alcohol added in small portions. 15 An alternative method of preparing cellulose esters consists in the partial displacement of the acid radical in a cellulose ester by treatment with another acid of higher ionisation constant (FR-A-702 116). The ester is heated at 20 about 100°C with the acid which, preferably, should be a solvent for the ester. By this means cellulose acetate-oxalate, tartrate, maleate, pyruvate, salicylate and phenylglycollate have been obtained, and from cellulose tribenzoate a cellulose benzoate-pyruvate. A cellulose 25 acetate-lactate or acetate-glycollate could be made in this way also. As an example cellulose acetate (10 g.) in dioxan (75 ml.) containing oxalic acid (10 g.) is heated at 100°C for 2 hours under reflux. 30 Multiple esters are prepared by variations of this process. A simple ester of cellulose, e.g. the acetate, is dissolved WO 2005/118761 PCT/EP2005/005121 - 13 - in a mixture of two (or three) organic acids, each of which has an ionisation constant greater than that of acetic acid (1.82 x 10"5) . With solid acids suitable solvents such as propionic acid, dioxan and ethylene dichloride are used. If 5 a mixed cellulose ester is treated with an acid this should have an ionisation constant greater than that of either of the acids already in combination. A cellulose acetate-lactate-pyruvate is prepared from 10 cellulose acetate, 40 per cent, acetyl (100 g.) , in a bath of 125 ml. pyruvic acid and 125 ml. of 85 per cent, lactic acid by heating at 100°C for 18 hours. The product is soluble in water and is precipitated and washed with ether- acetone. M.p. 230-250°C. 15 Other Substituents As well as the hydrophobic agent and optional deposition enhancing groups, pendant groups of other types may 20 optionally be present, i.e. groups which do not confer a softening benefit and which do not undergo a chemical change to enhance substrate affinity. Within that class of other groups is the sub-class of groups for enhancing the solubility of the material (e.g. groups which are, or 25 contain one or more free carboxylic acid/salt and/or sulphonic acid/salt and/or sulphate groups). Examples of solubility enhancing substituents include carboxyl, sulphonyl, hydroxyl, (poly)ethyleneoxy- and/or 30 (poly) propyleneoxy-containing groups, as well as amine groups. -07-2006 C4367 (C) WO (Amended 12 July 06) EP200500512 - 14 - The other pendant groups preferably comprise/from 0% to 65%, more preferably from 0% to 10% of the total number of pendant groups. The water-solubilising groups could comprise' from 0% to 100% of those other groups but 5 preferably from 0% to 20%, more preferably from 0% to 10%, still more preferably from 0% to 5% of, the total number of other pendant groups. A preferred group of polysaccharides (locust bean gum, for 10 example) have pendant galactose or other sugar residues which make them" effectively more water dispersible/soluble than unmodified cellulose, but which are not hydrolysed from the backbone under conditions of use. 15 The polysaccharide has a backbone comprising b1-4 linkages. It is a poly-glucan, poly-mannan, or gluco-mannan or mixtures thereof and preferably a galaoto-mannan or xylo-glucan or mixtures thereof. A particularly preferred group of polysaccharides is Locust Bean Gum, Tamarind xyloglucan, and 20 guar gum or mixtures thereof. In a further preferred embodiment the polysaccharide is cellulose monoacetate. The sugar polyester (SPE) 25 • The composition of the invention further comprises a sugar polyester (SPE). The SPE may or may not be chemically bonded to. the,./polysaccharide . Preferably, the SPE is not chemically bonded to the polysaccharide. In a further embodiment, some of the SPE is chemically bonded to the 30 polysaccharide, whilst some is not AMENDED SHEET WO 2005/118761 PCT/EP2005/005121 - 15 - By chemically bonded is meant the SPE is attached by a chemical bond (such as a covalent bond or an ionic bond) to the polysaccharide. 5 That sugar polyester which is not chemically bonded to the polysaccharide may be bonded thereto by a physical bond (such as hydrogen bonds, van der waal forces, hydrophobic interactions, electrostatic interactions, etc). 10 In the embodiment of the invention where some SPE is bonded to the polysaccharide by a chemical bond and some is not, the ratio of sugar polyester which is bonded to the polysaccharide by a chemical bond to that sugar polyester which is not bonded by a chemical bond is in the range of 15 from 1:1000 to 1:1 and preferably from 1:200 to 1:4. The sugar polyester is preferably selected from the group consisting of sucrose polyesters, glucose polyesters and cellobiose polyesters, and is most preferably a sucrose 20 polyester. Preferably, the ratio of the polysaccharide with the hydrophobic agent bonded thereto to the SPE is in the range of from' 1:200 to 1:5 and most preferably from around 1:20 to 25 1:8 parts by weight of the composition. Deposition of SPE onto a substrate includes deposition by adsorption, co-crystallisation, entrapment and/or adhesion. WO 2005/118761 PCT/EP2005/005121 - 16 – The Hydrophobic Agent The hydrophobic agent is one that renders the material more surface active than the polysaccharide alone. By surface 5 active is meant that the material tends to accumulate at oil/water interfaces and lower their surface tension. The hydrophobicity should not be so great as to prevent the dissolution or dispersion of the polysaccharide in water. 10 The hydrophobic agent is preferably selected from the group consisting of silicone, hydrocarbon and hydrophobic polymer. In one embodiment the hydrophobic agent is a silicone. 15 The hydrophobic agent is attached to the polysaccharide by a stable bond. That means that the bonding of the hydrophobic agent should be sufficiently stable so as not to undergo hydrolysis during processing or on storage prior to use or in the environment of the treatment process for the duration 20 of that process. For example, in laundry cleaning applications, the bond between the hydrophobic agent and polysaccharide should be sufficiently stable so that it does not undergo hydrolysis in the wash liquor, at the wash temperature, before the SPE has been deposited onto the 25 fabric. Preferably, the bond between the hydrophobic agent and the polysaccharide is such that the decay rate constant (kd) of the material in an aqueous solution at 0.01 wt% of the 30 material together with 0.1 wt% of anionic surfactant at a temperature of 4 0°C at a pH of 10.5 is such that WO 2005/118761 PCT/EP2005/005121 - 17 -kd Silicone Chain(s) as hydrophobic agent 5 In a preferred embodiment the hydrophobic agent is a silicone selected from polydialkyl siloxanes, amine derivatives thereof, and mixtures thereof wherein the silicone comprises silicone chains. 10 As used herein the term "silicone chain" means a polysiloxane or derivative thereof. The number average molecular weight (Mn) of the polysaccharide backbone may typically be in the range of 15 1,000 to 600,000, for example 2,000 to 400,000, e.g. as measured using GPC with multiple-angle, laser-scattering detection. Preferably, the average degree of substitution for the 20 silicone chains on the polysaccharide backbone is from 0.00001 to 0.5, more preferably 0.0001 to 0.5, still more preferably from 0.001 to 0.1 and even more preferably from 0.001 to 0.05. 25 Preferred silicone chains suitable for this use are those of formula: 30 WO 2005/118761 PCT/EP2005/005121 - 18 - wherein L is absent or is a linking group and one or two of substituents G -G is a methyl group, the remainder being selected from groups of formula m CH3 10 the -Si(CH3)20- groups and the -Si(CH3 0)(G4)- groups being arranged in random or block fashion, but preferably random. wherein n is from 5 to 1000, preferably from 10 to 200 and m 15 is from 0 to 100, preferably from 0 to 20, for example from 1 to 20. G4 is selected from groups of formula: 20 -(CH2)p-CH3, where p is from 1 to 18 — (CH2)q—MH—(CH2) r,_NH2 where q and r are independently from 1 to 3 — (CH2)S-NH2, where s is from 1 to 3 25 where t is from 1 to 3 WO 2005/118761 PCT/EP2005/005121 - 19 - -(CH2) u-COOH, where u is from 1 to 10, 5 10 where v is from 1 to 10, and -(CH2 CH20)W-(CH2)X H, where w is from 1 to 150, preferably from 10 to 20 and x is from 0 to 10; 15 and G5 is independently selected from hydrogen, groups defined above for G , -OH, -CH3 and -0(013)3. Synthetic Routes 20 Silicone chains as hydrophobic agent are preferably attached via a linking group "-L-". This linking group is the residue of the reactants used to form the bond between the hydrophobic agent and the polysaccharide. 25 For silicone chains as hydrophobic agent, one or more hydroxyl groups on the polysaccharide are reacted with a reactive group attached to the silicone chain, or the hydroxyl group(s) in question is/are converted to another group capable of reaction with a reactive group attached to 30 the silicone chain. WO 2005/118761 PCT/EP2005/005121 - 20 - Listed below, are suitable mutually reactive groups. In the case of hydroxyl groups, these may be the original hydroxyl group of the polysaccharide. However, either of a pair of these mutually reactive groups may be present on the 5 polysaccharide and the other attached to the silicone chain, or vice versa, the reaction chemistry being chosen appropriately.

Thus, the configuration as written is PSC-L-SXC. However, the reverse configuration SXC-L-PSC is also within the ambit of this definition and this is also mentioned where appropriate. 30 WO 2005/118761 PCT/EP2005/005121 - 21 - Preferred linking groups -L- are selected from amide, ester, ether, urethane, triazine, carbonate, amine and ester-alkylene linkages. 5 A preferred amide linkage is: 10 15 where G6 and G7 are each optionally present and are independently selected spacer groups, e.g. selected from C1_ 14 alkylene groups, arylene, Ci_4 alkoxylene, a residue of an oligo- or poly-ethylene oxide moiety, C1-4 alkylamine or a polyamine groups and G8 is hydrogen or C1-4 alkyl.

Emulsions 5 Compositions according to the present invention can be provided in the form of an emulsion for use in laundry or other fabric treatment compositions. 10 In a preferred embodiment, the emulsion comprises the polysaccharide having the hydrophobic agent bonded thereto and the sugar polyester, as the dispersed phase. The emulsions must contain another liquid component as well 15 as the SPE, preferably a polar solvent, such as water. The emulsion has typically from 30 to 99.9%, preferably from 40 to 99% of the other liquid component, preferably a polar solvent, most preferably water. Low water emulsions may be for example 30 to 60% water, preferably 40 to 55% water. 20 High water emulsions may be for example 60 to 99.9% water, preferably 80 to 99% water. Moderate water emulsions may be for example 55 to 8 0% water. The emulsion may contain an emulsifying agent, preferably an 25 emulsifying surfactant for the modified polysaccharide/SPE. In preferred cases, the modified polysaccharide is itself an emulsifying agent. In a further preferred case it is the sole emulsifying agent. WO 2005/118761 PCT/EP2005/005121 - 31 - The emulsifying agent is especially one or more surfactants, for example, selected from any class, sub class or specific surfactant(s) disclosed herein in any context. 5 The emulsifying agent most preferably comprises or consists of a non-ionic surfactant. Additionally or alternatively, one or more selected additional surfactants from anionic, cationic, zwitterionic and amphoteric surfactants may be incorporated in or used as the emulsifying agent. 10 Suitable non-ionic surfactants include the (poly)-alkoxylated analogues of saturated or unsaturated fatty alcohols, for example, having from 8 to 22, preferably from 9 to 18, more preferably from 10 to 15 carbon atoms on 15 average in the hydrocarbon chain thereof and preferably on average from 3 to 11, more preferably from 4 to 9 alkyleneoxy groups. Most preferably, the alkyleneoxy groups are independently selected from ethyleneoxy, propyleneoxy and butylenoxy, especially ethyleneoxy and propylenoxy, or 20 solely ethyleneoxy groups and alkyl polyglucosides as disclosed in EP 0 495 176. Preferably, the (poly)alkoxylated analogues of saturated or unsaturated fatty alcohols, have a hydrophilic-lipophilic 25 balance (HLB) of between 8 to 18. The HLB of a polyethoxylated primary alcohol nonionic surfactant can be calculated by WO 2005/118761 PCT7EP2005/005121 - 32 - HLB = MW (EO) x 100 MW(TOT) x 5 5 where MW (EO) = the molecular weight of the hydrophilic part (based on the average number of EO groups) 10 MW(TOT) = the molecular weight of the whole surfactant (based on the average chain length of the hydrocarbon chain) This is the classical HLB calculation according to Griffin 15 (J. Soc. Cosmetic Chemists, 5 (1954) 249-256). For analogous nonionics with a mix of ethyleneoxy (EO) , propylenoxy (PO) and/or butyleneoxy (BO) hydrophilic groups, the following formula can be used; 20 HLB = MW(EO) +0.57 MW(PO) + 0.4 MW (BO) MW (TOT) x 5 25 Preferably, the alkyl polyglucosides may have the following formula; R-0-Zn 30 in which R is a linear or branched, saturated or unsaturated aliphatic alkyl radical having 8 to 18 carbon atoms or WO 2005/118761 PCT/EP2005/005121 - 33 - mixtures thereof, and Zn is a polyglycosyl radical with n=1.0 to 1.4 hexose or pentose units or mixtures.

It should be noted that the modified polysaccharide is frequently not a pure material due to incomplete conversion and the ratio of the material as made to the emulsifying agent is typically around 3:1. 15 Further, in any such composition (especially emulsion components) the weight ratio of SPE to emulsifying agent is from 100:1 to 2:1, preferably from 60:1 to 5:1, more preferably around 33:1 (where the modified polysaccharide is not the sole emulsifying agent). 20 Emulsion Processing When in the form of an emulsion, the emulsion is prepared by mixing the modified polysaccharide and the SPE, other liquid 25 component (e.g. water) and preferably, also an emulsifying agent, such as' a surfactant, especially a non-ionic surfactant, e.g. in a high shear mixer. Whether or not pre-emulsified, the modified polysaccharide 30 and SPE composition may be incorporated by admixture with other components of a laundry treatment composition.

Many suitable surface-active compounds are available and are fully described in the literature, for example, in "Surface-Active Agents and Detergents", Volumes 5 I and II, by Schwartz, Perry and Berch. The preferred detergent-active compounds that can be used are soaps and synthetic non-soap anionic and non-ionic compounds. 10 The compositions of the invention may contain linear alkylbenzene sulphonate, particularly linear alkylbenzene sulphonates having an alkyl chain length of C8-C15. It is preferred if the level of linear alkylbenzene sulphonate is from 0 wt % to 30 wt %, more preferably 1 wt % to 25 wt %, 15 most preferably from 2 wt % to 15 wt %, by weight of the total composition.

It is preferred if the level of nonionic surfactant is from 0 wt% to 30 wt%, preferably from 1 wt% to 25 wt%, most 10 preferably from 2 wt% to 15 wt%, by weight of the total composition. Although the preferred embodiments of the present invention include those in which the hydrophobic agent bonded to the 15 polysaccharide is a conditioning and or softening species, any. conventional fabric conditioning agent may also be used in the compositions of the present invention. The conditioning agents may be cationic or non-ionic. 20 If the conventional fabric conditioning compound is to be employed in a main wash detergent composition comprising the polysaccharides of the present invention, the conventional fabric conditioning compound will typically be non-ionic. For use in the rinse phase, the non-polysaccharide 25 conditioner will typically be cationic. These may for example be used in amounts from 0.5% to 35%, preferably from 1% to 30% more preferably from 3% to 25% by weight of the composition. 30 Suitable cationic fabric softening compounds are substantially water-insoluble quaternary ammonium materials WO 2005/118761 PCT/EP2005/005121 - 38 - comprising a single alkyl or alkenyl long chain having an average chain length greater than or equal to C20 or/ more preferably, compounds comprising a polar head group and two alkyl or alkenyl chains having an average chain length 5 greater than or equal to C14.

Preferably these materials comprise small amounts of the corresponding monoester as described in US 4 137 180, for example, 1-hardened tallowoyloxy-2-hydroxy-3-trimethylammonium propane chloride. Other useful cationic softening agents are alkyl pyridinium salts and substituted imidazoline species. Also useful are 25 primary, secondary and tertiary amines and the condensation products of fatty acids with alkylpolyamines. The compositions may alternatively or additionally contain water-soluble cationic fabric softeners, as described in 30 GB 2 039 556B (Unilever).

The weight ratio of quaternary ammonium material or other cationic softening agent to fatty acid material is preferably from 10:1 to 1:10. 15 It is also possible to include certain mono-alkyl cationic surfactants which can be used in main-wash compositions for fabrics. Cationic surfactants that may be used include quaternary ammonium salts of the general formula R1R2R3R4N 20 X wherein the R groups are long or short hydrocarbon chains, typically alkyl, hydroxyalkyl or ethoxylated alkyl groups, and X is a counter-ion (for example, compounds in which R1 is a C8-C22 alkyl group, preferably a C8-C10 or C12-C14 alkyl group, R2 is a methyl group, and R3 and R4, which 25 may be the same or different, are methyl or hydroxyethyl groups); and cationic esters (for example, choline esters). The choice of surface-active compound (surfactant), and the amount present, will depend on the intended use of the WO 2005/118761 PCT/EP2005/005121 - 44 - detergent composition. In fabric washing compositions, different surfactant systems may be chosen, as is well known to the skilled formulator, for hand-washing products and for products intended for use in different types of washing 5 machine. The-total amount of surfactant present will also depend on the intended end use and may be as high as 60 wt%, for example, in a composition for washing fabrics by hand. In 10 compositions for machine washing of fabrics, an amount of from 5 to 40 % by weight of the total composition is generally appropriate. Typically the compositions will comprise at least 2 % surfactant e.g. from 2 to 60 %, preferably from 15 to 40 % most preferably from 25 to 35 % by 15 weight of the total composition. Detergent compositions suitable for use in most automatic fabric washing machines generally contain anionic non-soap surfactant, or non-ionic surfactant, or combinations of the 20 two in any suitable ratio, optionally together with soap.

The alkali metal aluminosilicate may be either crystalline or amorphous or mixtures thereof, having the general formula: 0.8-1.5 Na20. AI2O3. 0.8-6 Si02 20 These materials contain some bound water and are required to have a calcium ion exchange capacity of at least 50 mg CaO/g. The preferred sodium aluminosilicates contain 1.5-3.5 SiC>2 units (in the formula above). Both the amorphous and the 25 crystalline materials can be prepared readily by reaction between sodium silicate and sodium aluminate, as amply described in the literature. Suitable crystalline sodium aluminosilicate ion-exchange detergency builders are described, for example, in GB 1 429 143 (Procter & Gamble). 30 The preferred sodium aluminosilicates of this type are the WO 2005/118761 PCT/EP2005/005121 - 46 - well-known commercially available zeolites A and X, and mixtures thereof.

Especially preferred bleach precursors suitable for use in the present invention are N,N,N', N',-tetracetyl ethylenediamine (TAED) and sodium nonanoyloxybenzene sulphonate (SNOBS). The novel quaternary 10 ammonium and phosphonium bleach precursors disclosed in US 4 751 015 and US 4 818 426 (Lever Brothers Company) and EP 402 971A (Unilever), and the cationic bleach precursors disclosed in EP 284 292A and EP 303 520A (Kao) are also of interest. 15 The bleach system can be either supplemented with or replaced by a peroxyacid. examples of such peracids can be found in US 4 686 063 and US 5 397 501 (Unilever). A preferred example is the imido peroxycarboxylic class of peracids described in EP A 325 288, EP A 349 940, DE 382 3172 and EP 325 289. A 20 particularly preferred example is phthalimido peroxy caproic acid (PAP). Such peracids are suitably present at 0.1 - 12%, preferably 0.5 - 10%. A bleach stabiliser (transition metal sequestrant) may also 25 be present. Suitable bleach stabilisers include ethylenediamine tetra-acetate (EDTA), the polyphosphonates such as Dequest (Trade Mark) and non-phosphate stabilisers such as EDDS (ethylene diamine di-succinic acid). These bleach stabilisers are also useful for stain removal 30 especially in products containing low levels of bleaching species or no bleaching species. WO 2005/118761 PCT/EP2005/005121 - 49 - An especially preferred bleach system comprises a peroxy bleach compound (preferably sodium percarbonate optionally together with a bleach activator), and a transition metal bleach catalyst as described and claimed in EP 458 397A, EP 5 458 398A and EP 509 787A (Unilever). Bleach systems may comprise transition metal catalyst systems such as those disclosed in WO9965905; WO0012667; WO0012808; WO0029537, and, WO0060045. These catalyst systems have the 10 advantage that they require no added peroxyl compounds and can work, directly or indirectly, using atmospheric oxygen. The compositions according to the invention may also contain one or more enzyme(s). Suitable enzymes include the 15 proteases, amylases, cellulases, oxidases, peroxidases and lipases usable for incorporation in detergent compositions. Preferred proteolytic enzymes (proteases) are, catalytically active protein materials which degrade or alter protein types 20 of stains when present as in fabric stains in a hydrolysis reaction. They may be of any suitable origin, such as vegetable, animal, bacterial or yeast origin. Proteolytic enzymes or proteases of various qualities and 25 origins and having activity in various pH ranges of from 4-12 are available and can be used in the instant invention. Examples of suitable proteolytic enzymes are the subtilisins which are obtained from particular strains of B. Subtilis B. licheniformis, such as the commercially available subtilisins 30 Maxatase (Trade Mark), as supplied by Genencor International WO 2005/118761 PCT/EP2005/005121 - 50 - N.V., Delft, Holland, and Alcalase (Trade Mark), as supplied by Novozymes Industri A/S, Copenhagen, Denmark. Particularly suitable is a protease obtained from a strain of 5 Bacillus having maximum activity throughout the pH range of 8-12, being commercially available, e.g. from Novozymes Industri A/S under the registered trade-names Esperase (Trade Mark) and Savinase (Trade-Mark). The preparation of these and analogous enzymes is described in GB 1 243 785. Other 10 commercial proteases are Kazusase (Trade Mark obtainable from Showa-Denko of Japan), Optimase (Trade Mark from Miles Kali-Chemie, Hannover, West Germany), and Superase (Trade Mark obtainable from Pfizer of U.S.A.). 15 Detergency enzymes are commonly employed in granular form in amounts of from about 0.1 to about 3.0 wt%. However, any suitable physical form of enzyme may be used. The combination of non-cellulose polysaccharides and 20 cellulase enzymes is particularly useful, as these enzymes exhibit reduced activity against this class of polysaccharides, as compared to their activity against cellulose. Cellulase is known to be useful and is used in laundry products for de-fuzzing and colour brightening. 25 The compositions of the invention may contain alkali metal (preferably sodium) carbonate, in order to increase detergency and ease processing. Sodium carbonate may suitably be present in amounts ranging from 1 to 60 wt%, 30 preferably from 2 to 40 wt%. However, compositions WO 2005/118761 PCTYEP2005/005121 - 51 - containing little or no sodium carbonate are also within the scope of the invention. Powder flow may be improved by the incorporation of a small 5 amount of a powder structurant, for example, a fatty acid (or fatty acid soap), a sugar, an acrylate or acrylate/maleate copolymer, or sodium silicate. One preferred powder structurant is fatty acid soap, suitably present in an amount of from 1 to 5 wt%. 10 Other materials that may be present in detergent compositions of the invention include sodium silicate; anti-redeposition agents such as cellulosic polymers; soil release polymers; inorganic salts such as sodium sulphate; or lather boosters 15 as appropriate; dyes; coloured speckles; fluorescers and decoupling polymers.

However, many of these ingredients will be better delivered as benefit agent groups in materials according to the first aspect of the invention. 20 The detergent composition when diluted in the wash liquor (during a typical wash cycle) will typically give a pH of the wash liquor from 7 to 10.5 for a main wash detergent. 25 Particulate detergent compositions are suitably prepared by spray-drying a slurry of compatible heat-insensitive ingredients, and then spraying on or post-dosing those ingredients unsuitable for processing via the slurry. The skilled detergent formulator will have no difficulty in 30 deciding which ingredients should be included in the slurry and which should not. WO 2005/118761 PCT/EP2005/005121 - 52 - Particulate detergent compositions of the invention preferably have a bulk density of at least 400 g/1, more preferably at least 500 g/1. Especially preferred compositions have bulk densities of at least 650 g/litre, 5 more preferably at least 700 g/litre. Such powders may be prepared either by post-tower densification of spray-dried powder, or by wholly non-tower methods such as dry mixing and granulation; in both cases a 10 high-speed mixer/granulator may advantageously be used. Processes using high-speed mixer/granulators are disclosed, for example, in EP 340 013A, EP 367 339A, EP 390 251A and EP 420 317A (Unilever). 15 Liquid detergent compositions can be prepared by admixing the essential and optional ingredients thereof in any desired order to provide compositions containing components in the requisite concentrations. Liquid compositions according to the present invention can also be in compact 20 form which means it will contain a lower level of water compared to a conventional liquid detergent. Product Forms 25 Product forms include powders, liquids, gels, tablets, any of which are optionally incorporated in a water-soluble or water dispersible sachet. The means for manufacturing any of the product forms are well known in the art. If the composition comprising the modified polysaccharide and SPE 30 is to be incorporated in a powder (optionally the powder to be tableted), and whether or not pre-emulsified, it is WO 2005/118761 PCT/EP2005/005121 - 53 - optionally included in a separate granular component, e.g. also containing a water soluble organic or inorganic material, or in encapsulated form. 5 Substrate The substrate may be any substrate onto which it is desirable to deposit SPE and which is subjected to treatment such as a washing or rinsing process. 10 In particular, the substrate may be a textile fabric. It has been found that particular good results are achieved when using a natural fabric substrate such as cotton, or fabric blends containing cotton. 15 Treatment The treatment of the substrate with the material of the invention can be made by any suitable method such as 20 washing, soaking or rinsing of the substrate. Typically the treatment will involve a washing or rinsing method such as treatment in the main wash or rinse cycle of a washing machine and involves contacting the substrate with 25 an aqueous medium comprising the material of the invention. Examples The present invention will now be explained in more detail 30 by reference to the following non-limiting examples. WO 2005/118761 PCT/EP2005/005121 - 54 - In the following examples where percentages are mentioned, this is to be understood as percentage by weight. In the following tables where the values do not add up to 100 these are to be understood as parts by weight. 5 Example 1 - Synthesis of cellulose monoacetate (CMA) with grafted silicone Monocarboxydecyl terminated polydimethylsiloxane (PDMS) 10 source (Molecular weight 5,000: 1.5 g, 0.23 mmols) was dispersed in dimethylacetamide (10 cm3) by vigorous stirring under nitrogen. Carbonyldiimidazole (37 mg, 0.23 mmols) was then added and the dispersion heated with stirring to 70°C under nitrogen for two hours. A solution of cellulose 15 monoacetate (DS 0.58; 1 g, 5.3 mmol equivalents based on primary hydroxyl groups) in dimethylacetamide (10 cm3) was then added and stirring and heating was continued for a further 20 hours. Following this time the mixture was filtered and the filtrate added to vigorously stirred 20 acetone to give a white precipitate. This precipitate was filtered off, washed with acetone and dried under vacuum to give a white polymer (1.01 g) . From the aH NMR of the polymer (after hydrolysis with 20% DC1 in D20 for two hours at 80°C) and normalising the integration of the anomeric 25 protons to unity and the acetate group to 0.58 the integration of the Si-CH3 group (at 0.0 ppm) gives an overall degree of substitution (DS) of siloxane groups of 0.0015. This material is hereinafter referred to as "Polymer A". 30 WO 2005/118761 PCT/EP2005/005121 - 55 - Example 2 - Preparation of Locust Bean Gum with Grafted Silicone Lithium chloride (27 g) was dissolved in anhydrous dimethyl 5 sulfoxide (300 cm3) with heating (150°C) and stirring under nitrogen. Once the lithium chloride was dissolved the solution was cooled to 120 °C before slowly adding locust bean gum (3.5 g) over a period of 20 minutes with vigorous stirring. 10 The viscous solution thus obtained was then further cooled to 70 °C and carbonyl diimidazole (54 mg, 0.5 mmols) was added and stirring and heating was continued for a further two hours. Diaminopropyl terminated polydimethylsiloxane 15 (3,000 mwt, 1 g, 0.33 mmols) was then added and the solution stirred with heating for 18 hours. The solution was cooled to room temperature before adding drop-wise to vigorously stirred acetone (3 litres) to 20 precipitate the polymer. The suspension was centrifuged to isolate the product which was then washed with acetone (2 x 200 cm3) before drying under vacuum (40°C) overnight to give an off-white solid (3.1 g). 25 From the 2H NMR of the hydrolysed product (heated to 1 hour at 70°C in 20% DC1/D20) the degree of substitution of PDMS groups to sugar units was found to be 5.3 x 10~4. This material is hereinafter referred to as "Polymer B". WO 2005/118761 PCT/EP2005/005121 - 56 - Examples 3 and 4 - Preparation of sucrose polyester emulsions: Emulsions were prepared as using the formulations shown in 5 Table 1.

This mixture was agitated using an ultrasonic probe 15 (Soniprobe™) at half power until no undissolved polymer was visible (2-3 minutes). The ER-290 was then added to the bottle. The mixture was further agitated with the ultrasonic probe (1 minute at setting 6 followed by 2 x 1 minute at setting 8) to produce the emulsion. The same 20 process was used to produce the control emulsion but no polymer was used. WO 2005/118761 PCT/EP2005/005121 - 57 - Example 5 - Treatment of Fabrics with Detergent composition containing emulsion Example 3 Wash liquors were prepared by adding 2.84 g of the 3 5 formulations given in Table 2 to 150 cm of water.

To each pot was added a piece of white 100% cotton terry 15 towelling weighing 18 g along with 25 stainless steel balls. The pots were sealed and then washed for 45 minutes with end over end agitation at 40 rpm. At the end of the wash period, the liquor was decanted from each of the pots, which were then refilled with 250 cm of water, resealed, replaced in WO 2005/118761 PCT/EP2005/005121 - 58 - the Rotawash and washed for a further ten minutes. This rinse step was repeated one more time after which, the rinse liquor was decanted from the pots, the cloths gently squeezed by hand to remove excess water and the fabrics dried flat 5 overnight under ambient conditions. Each condition was run in duplicate. The quantity of SPE deposited onto the fabrics during the wash was then determined as follows. Each fabric piece was 10 cut into three and the individual pieces weighed. Each fabric piece was added to a bottle containing 50 cm of tetrahydrofuran (THF) and the deposited SPE extracted with the aid of ultrasonication for five minutes. The amount of SPE extracted was determined by gel permeation chromatography 15 (GPC) using a PLgel 3um 100A column with THF eluent and an evaporative light scattering detector ELS 1000 light scattering detector. The area under the elution peak for the SPE was calculated by integration of the trace and this area was used to calculate the concentration of SPE in the THF 20 solution from the extraction by comparison to a calibration curve produced using SPE in THF standards. The results from the three portions of cloth were used to calculate an average value for the amount of SPE deposited on the fabric expressed as milligrams of SPE deposited per gram of fabric.
