Specification

FORM-2 THE PATENTS ACT, 1970 (39 of 1970) & The Patents Rules, 2003 COMPLETE SPECIFICATION (See Section 10 and Rule 13} LAUNDRY COMPOSITIONS HINDUSTAN UNILEVER LIMITED, a company incorporated under the Indian Companies Act, 1913 and having its registered office at 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 IMPROVEMENTS RELATING TO FABRIC CLEANING Technical Field 5 The present invention is concerned with improvements relating to fabric cleaning and, in particular, with an improved process for laundering fabrics using a concentrated detergent. 10 Background Isotropic liquid detergents for use in laundry comprise varying concentration levels of surfactant. 10 to 15 %wt is 15 commonplace in Portugal and Spain, 18 to 27 %wt typical in the Benelux countries, Germany and Italy, while levels of 35 to 40 %wt surfactant have been used in the UK and France. While moderately concentrated detergent compositions for 20 laundry use have been known from the literature and available in the marketplace for some time, there has been a recent trend towards more concentrated liquid products and a "three-times concentrate" (Persil ™ "Small and Mighty") was launched in the UK. The dosage instructions for this 25 product suggest that 35 ml of the composition should be used for a normal product load. With less concentrated products volume dosages are typically higher, so as to reach the same in-wash concentrations of non-soap surfactant. Reasons for this trend towards' concentrated products have included a desire to make more environmentally friendly products, which use less packaging, require fewer chemicals for their manufacture and require less energy to manufacture 5 and transport them. Concentrated products also offer the advantages of taking up less shelf and storage space. Concentrated products deliver the same level of surfactant into the wash liquor from a smaller volume of product, and they are generally formulated by taking water out. 10 However, there are limits to the extent to the benefits which can be obtained by simply concentrating products. Particular problems occur with dispensing and delivery of products. For example, at particularly high concentrations 15 liquid products may exhibit unacceptable or unstable viscosities and solid products may exhibit hydroscopicity and poor flow or caking. These known disadvantages, such as maintenance of product stability, pourability and product appearance have lead to a number of proposals. 20 A "four times" concentrate has been launched in /Australia under the brand name "Orange power" and is described as "a 4x concentrate enzyme liquid detergent". Its dosage recommendation. is 2.5 ml (a capful) for top loading washing 25 machines and of a cap for front loaders. Unit dosage has been suggested to overcome some of the known problems but this can lead to dissolution problems. Moreover, rising cost of surfactants, especially those from oil-based materials has led to pressures to remove surfactant as well. WO 2004/074419 {Novozyme) suggests the replacement of part 5 of the surfactant, builder, bleach, and fillers in a detergent with enzymes. This is said to result in a significant reduction of the volume and weight of the detergent necessary for one wash. After partial replacement by enzymes, levels of surfactant of less than 30 wt% 10 preferably 4 to 20wt%, more preferably 5 to 15 wt% are disclosed. Any soil suspending polymer is said to be reduced to 0 to 6 wt% after it too is partially or fully replaced by enzymes. Lipase is used to boost oily soil detergency. In the examples in-wash non-soap surfactant 15 levels as low as O.18 g/L are disclosed. The drawback with the approach suggested in this document is that it is too dependent on enzymes which are expensive and are sensitive to storage and use conditions. Furthermore the stains selected to exemplify cleaning are apparently chosen to be 20 responsive to enzymes and consequently do not demonstrate the solution to the more realistic problem of detergency against everyday dirt and stains, such as clay. WO 2006/113314 5mg, pref greater than 8mg per wash). This means that the amount in the composition is higher than typically found in ■liquid detergents. This can be seen by the ratio of non-10 soap surfactant to lipase enzyme, in particular. A particularly preferred lipase enzyme is available under the trademark Lipoclean™ from Novozymes. As will be described in further detail below, a range of 15 possible polymers may be employed to improve the performance of the compositions used in the method of the present invention. Again, the efficacy of these polymers is much improved by the reduction in the level of surfactant present in the wash. The ratio of polymer to surfactant is also set 20 to be higher than normal. One preferred class of polymer is the fabric-substantive polymers comprising at least one of (i) saccharide or (ii) dicarboxylic acid and polyol monomer units. Typically these 25 have soil release properties while they can have a primary detergency effect the generally assist in subsequent cleaning. Preferably these should be present at a level of at least 2%wt preferably at least 3% of the composition. Another particularly preferred class of polymer is polyGthyleno imino; pjg^£ocab3.y modified polyethylene imine. Polyethylene imines are materials composed of ethylene imine units -CH2CH2NH- and, where branched, the hydrogen on the 5 nitrogen is replaced by another chain of ethylene imine units. These polyethyleneimines can be prepared, for example, by polymerizing ethyleneimine in the presence of a catalyst such as carbon dioxide, sodium bisulfite, sulfuric acid, hydrogen peroxide, hydrochloric acid, acetic acid, and 10 the like. Specific methods for preparing these polyamine backbones are disclosed in U.S. Pat. No. 2,182,306, Ulrich et al., issued Dec. 5, 1939; U.S. Pat. No. 3,033,746, Mayle et al., issued May 8, 1962; U.S. Pat. No. 2,208,095, Esselmann et al., issued Jul. 16, 1940; U.S. Pat. No. 15 2,806,839, Crowther, issued Sep. 17, 1957; and U.S. Pat. No. 2,553,696, Wilson, issued May 21, 1951. Preferentially, these comprise a polyethyleneimine backbone of about 300 to about 10000 weight average molecular weight; 20 wherein the modification of the polyethyleneimine backbone is: a-) ene—«-3r^fe+/-Q-^4-ke->ty4-a-t4ren-HTi©d-i#iea-tiQn-s in the polyethyleneimine backbone, the alkoxylation modification comprising the replacement of a hydrogen 25 atom by a polyalkoxylene chain having an average of about 1 to about 40 alkoxy moieties per modification, wherein the terminal alkoxy moiety of the alkoxylation modification is capped with hydrogen, a C1-C4 alkyl, an anionic group or mixtures thereof; b) a substitution of one C1-C4 alkyl moiety and one or two alkoxylation modifications per nitrogen atom in the polyethyleneimine backbone, the alkoxylation modification comprising the replacement of a hydrogen 5 atom by a polyalkoxylene chain having an average of about 1 to about 40 alkoxy moieties per modification wherein the terminal alkoxy moiety is capped with hydrogen, a C1-C4 alkyl an anionic group or mixtures thereof; or 10 c) a combination thereof. The polyethyleneimine polymer is present in the composition provided in step (a), prior to the dilution step (b), 15 preferably at a level of between 0.01 and 25 wt%, but more preferably at a level of at least 3 wt% and/or less than 9.5 wt% , most preferably from 4 to 9 wt% and with a ratio of non-soap surfactant to EPEI of from -SH-S- to 11 ^, preferably from 4.; 3. to 1: £., or even to -l-rS . 20 The combination of low non-soap surfactant and the presence "G-j^-feG-fe-h—M-p a-se—a-Hd—peiy e%fe-yl-ene irm-irH-e-4>a-s—fe eei=>—f^uftd particularly advantageous and a preferred method of laundering fabric according the present invention comprises 25 the steps of: a) providing a pourable liquid detergent composition comprising: i) 10-405 wt of surfactant, essentially consisting of nonionic and/or anionic and/or zwitterionic surfactant which 10-40% wt of surfactant 5 preferably passes the Calcium Tolerance Test described herein, and in addition, no more than 1S% wt, preferably no more than 10%wt, of a soap, with the proviso that any soap present is present as a minority In wt% terras of the total 10 surfactant, ii) 5 to 20000 LU/g of a lipase, and, iii) 0.01/ preferably 3, to 25 wt%/polyethyleneimine; 15 b) diluting a dose of said detergent composition in water by a factor of greater than 500 to obtain a wash liquor which comprises 0.8 to 0.05 g/1 of non-soap surfactant, and 20 c) contacting said wash-liquor with fabrics. Significantly, the compositions of the invention, while using less surfactant per wash than fully formulated 25 commercial compositions exhibit at least parity in performance and on many stains and dirt show improved performance. In a second aspect the invention therefore comprises the compositions of step {a) of the process provided either in a multidose container or in the form of a liquid unit dose in a soluble sachet. 5 In a third aspect of the invention the concentrated composition is prediluted with a small amount of water to enable the normal volume to be dosed (e.g. 35 ml). This retains the advantages of a low amount of chemical dosed per 10 wash and if the dilution step is carried out when the composition is bottled it can aid in the stability of the formuiation on storage. When this process modification is used the dilution factor will be adjusted to compensate for the greater dose of more dilute material added to the wash, 15 Thus the extent of dilution can be as low as 280 volumes of water to one dose from the bottle of the concentrate with extra make up water in a multi-dose bottle. Thus according to a third aspect of the invention there is 20 provided a method of laundering fabric which comprises the steps of: a) providing a multidose container which contains a pourable liquid detergent composition comprising/10-4 0% 25 wt of surfactant, essentially consisting of nonionic and/or anionic and/or zwitterionic surfactant, and in .addition, no more than 15% wt, preferably no more than 10%wt, of a soap, with the proviso that any soap present is present as a minority in wtS terms of the 30 total surfactant, b) mixing a dose of the detergent composition comprising 4 to 8 g non-soap surfactant/and at least 0.5 g of polyethyleneimine with water to obtain a wash liquor and, 5 c) washing fabrics with the wash liquor so formed. Advantageously, the dose in step (b) further comprises at least 0,01 g active lipase protein (or greater than 2500 10 LU) . It may altornotivcly,—ox additionally,—eemprise at-j:ttaa-b-6HiJg of soil roloooc polymoj!?. The dose, prior to dilution, should contain 5 to 20 000 LU/g when lipase is present. 15 Detailed Description of 'the Invention In order that the invention may be further and better understood and carried forth into practice it will be described hereinafter with reference to various preferential 20 but non-limiting features. -Su-S^ie^fi afi-t s-5 —— — ; Surfactants assist in removing soil from the textile 25 materials and also assist in maintaining removed soil in solution or suspension in the wash liquor. Anionic and/or nonionic surfactants, preferably in a calcium tolerant blend, are an essential feature of the present invention. Surfactant systems which consist only of linear alkyl 30 benzene sulphonate (LAS) are generally calcium intolerant. When required, in order to ensure calcium tolerance, surfactant systems should generally avoid having levels of LAS above 90 %wt. Nonionic-free systems with 95 %wt LAS can be made provided that some zwitterionic surfactant, such as 5 sulphobetaine, is present. Generally it is preferred to use less than 90 %wt LAS and at least lQ%wt of nonionic surfactant. Preferred alkyl ether sulphates are C8-C15 alkyl and have 2-10 10 moles of ethoxlation. Preferred alkyl sulphates are alkylbenzene sulphonates, particularly linear alkylbenzene sulphonates having an alkyl chain length of C8-C15. The counter ion for anionic surfactants is generally an alkali metal, typically sodium, although other counter-ions such as 15 MEA, TEA or ammonium can be used. Suitable anionic surfactant materials are available in the marketplace as the '"Genapol'™ range from Clariant. Nonionic surfactants include primary and secondary alcohol 20 ethoxylates, especially C8-C20 aliphatic alcohol ethoxylated with an average of from 1 to 20 moles of ethylene oxide per mole of alcohol, and more especially the C10-C15 primary and secondary aliphatic alcohols ethoxylated with an average of from 1 to 10 moles of ethylene oxide per mole of alcohol. 25 Non-ethoxylated nonionic surfactants include alkyl polyglycosides, glycerol monoethers and polyhydroxy amides (glucamide). Mixtures of nonionic surfactant may be used. When included therein the composition contains from 0.2 wt% to 40 wt%, preferably 1 wt% to 20 wt%, more preferably 5 to 30 15 wt% of a non-ionic surfactant, such as alcohol ethoxylate, nonylphenol ethoxylate, alkylpolyglycoside, alkyldimethylamineoxide, ethoxylated fatty acid monoethanolamide, fatty acid monoethanolamide, polyhydroxy alkyl fatty acid amide, or N-acyl N-alkyl derivatives of 5 glucosamine ("glucamides"). Nonionic surfactants that may be used include the primary and secondary alcohol ethoxylates, especially the C8-C20 aliphatic alcohols ethoxylated with an average of from 1 to 35 moles of ethylene oxide per mole of alcohol, and more 10 especially the C10-C15 primary and secondary aliphatic alcohols ethoxylated with an average of from 1 to 10 moles of ethylene oxide per mole of alcohol. Shading Dyes: 15 As noted above, shading dye can be used to improve the performance of the compositions used in the method of the present invention. The deposition of shading dye onto fabric is improved when they are used in compositions of the 20 invention and according to the process of the invention. Preferred dyes are violet or blue. It is believed that the deposition on fabrics of a low level of a dye of these shades, masks yellowing of fabrics. A further advantage of shading dyes is that they can be used to mask any yellow 25 tint in the composition itself.

A particularly preferred embodiment, the present invention 15 provides a method of laundering fabric which comprises the steps of: a) providing a pourable liquid detergent composition (preferably with the above-mentioned enzyme and 20 polymers present) comprising: i) a blue violet dye, preferably with an optical adsorption peak in the range 540-600nm, preferabl a bis-azo direct dye, preferably at a level of 25 0.000001-lwt%, ii) optionally fluorescer, preferably at a level of 0.005 to 2 wt %, and, iii) 10-40% wt of surfactant, essentially consisting of nonionic and/or anionic ancf/or zwitterionic surfactant which 10-40% wt of surfactant 5 preferably passes the Calcium Tolerance Test described herein, and in addition, no more than 15% wt, preferably no more than 10%wt, of a soap, with the proviso that any soap present is present as a minority in wt% terms of the total 10 surfactant, b) diluting a dose of said detergent composition in water by a factor of greater than 500 to obtain a wash liquor which Comprises 0.8 to 0.035 g/1 of non-soap 15 surfactant, and c) washing fabrics with the wash liquor so formed. Polymers: 20 The composition preferably comprises one or more polymers. polymers can assist in the cleaning process by helping to retain soil in solution or suspension and/or preventing the transfer of dyes. Polymers can also assist in the soil 25 removal process. Dye transfer, anti-redeposition and soil-release polyniers are described in further detail below. Dye transfer inhibitors: Detergent compositions often employ polymers as so-called Mye-transfer inhibitors'. These prevent migration of dyes, 5 especially during long soak times.

A single or a number of amine functions are reacted with one or more 20 alkylene oxide groups to form a polyalkylene oxide side chain. The alkylene oxide can be a homopolymer (for example ethylene oxide) or a random or block copolymer. The terminal group of the alkylene oxide side chain can be further reacted to give an anionic character to the molecule (for 25 example to give carboxylic acid or sulphonic acid functionality). Preferably the composition according to the present invention comprises a dye transfer inhibition agent selected 30 from polyvinylpyrridine N-oxide (PVNO), polyvinyl pyrrolidone (PVP), polyvinyl imidazole, N-vinylpyrrolidone and N-vinylimidazole copolymers (PVPVI), copolymers thereof, and mixtures thereof. 5 The amount of dye transfer inhibition agent in the composition according to the present invention will be from 0.01 to 10 %, preferably from 0.02 to 8, or even to 5 %, more preferably from 0.03 to 6, or even to 2 %, by weight of the composition. It will be appreciated that the dye 10 transfer inhibition agents will assist in the preservation of whiteness by preventing the migration of dyes from place to place. This preservation of whiteness assists in cleaning and counteracts the reduction in surfactants present in the wash liquor. 15 Anti-redeposition polymers: Anti-redeposition polymers are typically polycarboxylate materials. Polycarboxylate materials, which can be prepared 20 by polymerizing or copolymerizing suitable unsaturated monomers, are preferably admixed in their acid form. Unsaturated monomeric acids that can be polymerized to form suitable polycarboxylates include acrylic acid, maleic acid (or maleic anhydride), fumaric acid, itaconic acid, aconitic 25 acid, mesaconic acid, citraconic acid and methylenemalonic acid. The presence in the polycarboxylates herein of monomeric segments, containing no carboxylate radicals such as vinylmethyl ether, styrene, ethylene, etc. is suitable provided that such segments do not constitute more than 30 about 4 0% by weight of the polymer. Particularly suitable polycarboxylates can be derived from acrylic acid. Such acrylic acid-based polymers which are useful herein are the water-soluble salts of polymerized acrylic acid. The average molecular weight of such polymers 5 in the acid form preferably ranges from about 2,000 to 10,000, more preferably from about 4,000 to 7,000 and most preferably from about 4,000 to 5,000. Water-soluble salts of such acrylic acid polymers can include, for example, the alkali metal, ammonium and substituted ammonium salts. 10 Soluble polymers of this type are known materials. Use of polyacrylates of this type in detergent compositions has been disclosed, for example, in Diehl, U.S. Pat. No. 3,308,067, issued Mar. 7, 1967. In the present invention, the preferred polycarboxylate is sodium polyacrylate. 15 Acrylic/maleic-based copolymers may also be used as a preferred component of the anti-redeposition agent. Such materials include the water-soluble salts of copolymers of acrylic acid and maleic acid. The average molecular weight 20 of such copolymers in the acid form preferably ranges from about 2,000 to 100,000, more preferably from about 5,000 to 75,000, most preferably from about 7,000 to 65,000. The ratio of acrylate to maleate segments in such copolymers will generally range from about 30:1 to about 1: 1, more 25 preferably from about 10:1 to 2:1. Water-soluble salts of such acrylic acid/maleic acid copolymers can include, for example, the alkali metal, ammonium and substituted ammonium salts. Soluble acrylate/maleate copolymers of this type are known materials which are described in European Patent 30 Application No. 66915, published Dec. 15, 1982, as well as in EP 193,360, published Sep. 3, 1986, which also describes such polymers comprising hydroxypropylacrylate. Still other useful polymers maleic/acrylic/vinyl alcohol terpolymers. Such materials are also disclosed in EP 193,360, including, 5 for example, the 45/45/10 terpolymer of acrylic/maleic/vinyl alcohol. Polyethylene glycol (PEG) can act as a clay soil removal-antiredeposition agent. Typical molecular weight ranges for 10 these purposes range from about 500 to about 100,000, preferably from about 1,000 to about 50,000, more preferably from about 3,000 to about 10,000. Polyaspartate and polyglutamate dispersing agents may also be used. Any polymeric soil release agent known to those skilled in 15 the art can optionally be employed in compositions according to the invention. Polymeric soil release agents are characterized by having both hydrophilic segments, to hydrophilize the surface of hydrophobic fibres, such as polyester and nylon, and hydrophobic segments, to deposit 20 upon hydrophobic fibres and remain adhered thereto through completion of washing and rinsing cycles and, thus, serve as an anchor for the hydrophilic segments. This can enable stains occurring subsequent to treatment with the soil release agent to be more easily cleaned in later washing 25 procedures. The amount of anti redeposition polymer in the composition according to the present invention will be from 0.01 to 10 %, preferably from 0.02 to 8 %, more preferably from 0.03 to 30 6 %, by weight of the composition. Soil Release Polymers: Generally the soil release polymers for polyester will comprise polymers of aromatic dicarboxylic acids and 5 alkylene glycols (including polymers containing polyalkyiene glycols). The polymeric soil release agents useful herein especially include those soil release agents having: 10 (a) one or more nonionic hydrophilic components consisting essentially of: (i) polyoxyethylene segments with a degree of polymerization of at least 2, or 15 (ii) oxypropylene or polyoxypropylene segments with a degree of polymerization of from 2 to 10, wherein said hydrophile segment does not encompass any oxypropylene unit unless it is bonded to adjacent 20 moieties at each end by ether linkages, or (iii)a mixture of oxyalkylene units comprising oxyethylene and from 1 to about 30 oxypropylene units wherein said mixture contains a sufficient 25 amount of oxyethylene units such that the hydrophile component has hydrophilicity great enough to increase the hydrophilicity of conventional polyester synthetic fiber surfaces upon deposit of the soil release agent on such 30 surface, said hydrophile segments preferably comprising at least about 25% oxyethylene units and more preferably, especially for such components having about 20 to 30 oxypropyiene 5 units, at least about 50% oxyethylene units; or (b) one or more hydrophobe components comprising: (i) C3 oxyalkylene terephthalate segments, wherein, if 10 said hydrophobe components also comprise oxyethylene terephthalate, the ratio of oxyethylene terephthalate:C3 oxyalkylene terephthalate units is about 2:1 or lower, 15 (ii) C4 -Ce alkylene or oxy C4-C6 alkylene segments, or mixtures therein, (iii)poly (vinyl ester) segments, preferably polyvinyl acetate), having a degree of polymerization of at 20 least 2, or (iv) C1 -C4 alkyl ether or C4 hydroxyalkyl ether substituents, or mixtures therein, wherein said substituents are present in the form of C-1 -C4 alkyl ether or C4 hydroxyalkyl ether cellulose derivatives, or mixtures therein, 25 and such cellulose derivatives are amphiphilic, whereby they have a sufficierit level of C1-C4 alkyl ether and/or C4 hydroxyalkyl ether units to deposit upon conventional polyester synthetic fiber surfaces and retain a Sufficient level of 30 hydroxyls, once adhered to such conventional synthetic fiber surface, to increase fiber surface hydrophilicity, or a combination of (a) and (b). 5 Typically, the polyoxyethylene segments of (a)(i) will have a degree of polymerization of from about 200, although higher levels can be used, preferably from 3 to about 150, more preferably from 6 to about 100. Suitable oxy C4 -C6 alkylene hydrophobe segments include, but are not limited 10 to, end-caps of polymeric soil release agents such as MO3 S(CH2)n OCH2 CH2 0--, where M is sodium and n is an integer from 4-6, as disclosed in U.S. Pat. No. 4,721,580, issued Jan. 26, 1988 to Gosselink. 15 Soil release agents characterized by poly(vinyl ester) hydrophobe segments include graft copolymers of poly(vinyl ester), e.g., C1 -C6 vinyl esters, preferably poly(vinyl acetate) grafted onto polyalkylene oxide backbones, such as polyethylene oxide backbones. See European Patent 20 Application 0 219 048, published Apr. 22, 1987 by Kud, et al. Commercially available soil release agents of this kind include the SOKALAN type of material, e.g., SOKALAN HP-22, available from BASF (West Germany). 25 One type of preferred soil release agent is a copolymer having random blocks of ethylene terephthalate and polyethylene oxide (PEO) terephthalate. The molecular weight of this polymeric soil release agent is in the range of from about 25,000 to about 55,000. See U.S. Pat. No. 3,959,230 to HayS/ issued May 2b, 1976 and U.S. Pat. No. 3,893,929 to Basadur issued Jul. 8, 1975. Another preferred polymeric soil release agent is a 5 polyester with repeat units of ethylene terephthalate units contains 10-15% by weight of ethylene terephthalate units together with 90-80% by weight of polyoxyethylene terephthalate units, derived from a polyoxyethylene glycol of average molecular weight 300-5,000. Examples of this 10 polymer include the commercially available material ZELCON 5126 (from DuPont) and MILEASE T (from ICI). See also U.S. Pat. No. 4,702,857, issued Oct. 27, 1987 to Gosselink. Another preferred polymeric soil release agent is a 15 sulfonated product of a substantially linear ester oligomer comprised of an oligomeric ester backbone of terephthaloyl and oxyalkyleneoxy repeat units and terminal moieties covalently attached to the backbone. These soil release agents are described fully in U.S. Pat, No. 4,968,451, 20 issued Nov. 6, 1990 to J.J. Scheibel and E. P. Gosselink. Other suitable polymeric soil release agents include the terephthalate polyesters of U.S. Pat. No. 4,711,730, issued Dec. 8, 1987 to Gosselink et al, the anionic end-capped oligomeric esters of U.S. Pat. No. 4,721,580, issued Jan, 25 26, 1988 to Gosselink, and the block polyester oligomeric compounds of U.S. Pat. No. 4,702,857, issued Oct. 27, 1987 to Gosselink. Preferred polymeric soil release agents also include the 30 soil release agents of U.S. Pat. No. 4,877,896, issued Oct. 31, 1989 to Maldonado et al, which discloses anionic, especially sulfoarolyl, end-capped terephthalate esters. If utilized, soil release agents will generally comprise 5 from about 0.01% to about 10.0%, by weight, of the detergent composition, typically greater than or equal to 0.2 wt% even from 3 wt% to 9 wt%, but more preferably they are used at greater than 1 wt%, even greater than 2 wt% and most preferably greater than 3 wt%, even more preferably greater 10 than 5 wt%, say 6 to 8 wt% in the composition. Still another preferred soil release agent is an oligomer with repeat units of terephthaloyl units, sulfoisoterephthaloyl units, oxyethyleneoxy and oxy-1,2-propylene units. The repeat units forin the backbone of the 15 oligomer and are preferably terminated with modified isethionate end-caps. A particularly preferred soil release agent of this type comprises about one sulfoisophthaloyl unit, 5 terephthaloyl units, oxyethyleneoxy and oxy-1,2-propyleneoxy units in a ratio of from gibout 1.7 to about 20 1.8, and two end-cap units of sodium 2-(2-hydroxyethoxy)- ethanesulfonate. Said soil release agent also comprises from about 0.5% to about 20%, by weight of the oligomer, of a crystalline-reducing stabilizer, preferably selected from the group consisting of xylene sulfonate, cumene sulfonate, 25 toluene sulfonate, and mixtures thereof. Suitable soil release polymers are described in WO 2008095626 (Clariant); WO 2006133867 (Clariant); WO 2006133868 (Clariant); WO 2005097959 (Clariant); WO 9858044 30 (Clariant); WO 2000004120 (Rhodia Chimie); US 6242404 (Rhodia Inc); WO 2001023515 (Rhodia Inc); WO 9941346 (Rhodia Chim); WO 9815346 (Rhodia Inc); WO 9741197 (BASF); EP 728795 (BASF); US 5008032 (BASF); WO 2002077063 (BASF); EP 483606 ( BASF); EP 442101 (BASF); WO 9820092 (Proctor & Gamble); EP 5 201124 (Proctor & Gamble); EP 199403 (Proctor & Gamble); DE 2527793 (Proctor & Gamble); WO 9919429 (Proctor & Gamble); WO 9859030 (Proctor & Gamble); US 5834412 (Proctor & Gamble); WO 9742285 (Proctor & Gamble); WO 9703162 (Proctor & Gamble); WO 9502030 (Proctor & Gamble); WO 9502028 10 (Proctor & Gamble); EP 357280 (Proctor & Gamble); US 4116885 (Proctor & Gamble); WO 9532232 (Henkel); WO 9532232 (Henkel); WO 9616150 (Henkel); WO 9518207 (Henkel); EP 1099748 (Henkel); FR 2619393 (Colgate Palmolive); DE 3411941 (Colgate Palmolive); DE 3410810 (Colgate Palmolive); WO 15 2002018474 (RWE-DEA MINERALOEL & CHEM AG; SASOL GERMZUSIY GMBH); EP 743358 (Textil Color AG); PL 148326 (Instytut Ciezkiej Syntezy Organicznej "Blachownia", Pol-); JP 2001181692 (Lion Corp); JP 11193397 A (Lion Corp); RO 114357 (S.C. "Prod Cresus" S.A., Bacau, Rom.); and US 7119056 20 (Sasol). Particularly preferred are combinations of relatively high levels of EPEI (>5wt% on the composition) with soil release polymers, especially, but not exclusively, if betaine is 25 included in the surfactant system. We have determined that combination of EPEI and soil release polymers of the above types enables increased performance at lower surfactant levels compared to l.Og/L or higher non 30 soap surfactant wash liquors with betaine but without either EPEI or SRP. This effect is particularly visible on a range of stains on polyester, most particularly red clay. The effect of the combination on sunflower oil and foundation is also beneficial. SRP performance is enhanced significantly 5 by repeated fire-treatment. There is some evidence of a build-up effect of EPEI performance. The most preferred soil release polymers are the water soluble/miscible or dispersible polyesters such as: linear 10 polyesters Sold under the Repel-0-Tex brand by Rhodia (gerol), lightly branched polyesters sold under the Texcare brand by Clariant, especially Texcare SRN170, and heavily branched polyesters such as those available from Sasol and described in us 7119056. 15 Enzymes: One or more Enzymes may be present in a composition of the invention and when practicing a method of the invention. 20 Lipase: As noted above, suitable lipases include those of bacterial or fungal origin. Chemically modified or protein engineered mutants are included. Examples of useful lipases include lipases from Humilcola (synonym Thermomyces) , e.g. from H. 25 lanuginosa (T. lanuginosus) as described in EP 258 0 68 and EP 305 216 or from H. insolens as described in WO 96/13580, a Pseudomonas lipase, e.g. from P. alcaligenes or P. pseudoalcaligsnes (EP 218 272), P. cepacia (EP 331 376), P. stutzeri (GB 1,372,034), P. fluorescens, Pseudomonas sp. 30 strain SD 705 (wo 95/06720 and WO 96/27002), p. wisconsinensis (WO 96/12012), a Bacillus lipase, e.g. from B. subtilis (Dartois et al. (1993), Biochemica et Biophysica Acta, 1131, 253-360), B. stearothermophilus (JP 64/744992) or B. pumilus (WO 91/16422). As noted above 5 the preferred ones have a high degree of homology with the wild-type lipase derived from Hjjmlcola lanugxnose. Other examples are lipase variants such as those described in WO 92/05249, WO 94/01541, EP 407 225, EP 260 105, 10 WO 95/35381, WO 96/00292, WO 95/30744, WO 94/25578, WO 95/14783, WO 95/22615, WO 97/04079 and WO 97/07202. Preferred commercially available lipase enzymes include Lipolase™ and Lipolase Ultra™, LipexTM and Lipoclean™ 15 (Novozymes A/S). In addition to or as an alternative to lipase one or more other enzymes may be present. However lipase is particularly preferred. 20 Advantageously, the presence of relatively high levels of calcium in the poorly built or unbuilt compositions of the invention has a beneficial effect on the turnover of certain enzymes, particularly lipase enzymes and preferably lipases 25 from Humicola, The preferred lipases include first wash lipases which comprise a polypeptide having an amino acid sequence which has at least 90% sequence identity with the wild-type lipase 30 derived from Humicola lanuginosa strain DSM 4109 and compared to said wild-type lipase, comprises a substitution of an electrically neutral or negatively charged amino acid within 15 A of El or Q24 9 with a positively charged amino acid; and may further comprise: 5 (I) a peptide addition at the C-terminal;
