-> C4283 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, Mumbai -400 020, Maharashtra, India The following specification particularly describes the invention and the manner in which it is to be performed. WO 2004/056952 PCT/EP2003/013825, 1 LAUNDRY TREATMENT COMPOSITIONS 5 Technical Field The present invention relates to laundry treatment compositions comprising a modified silicone polymeric material and use of such a material to deposit on a substrate and 10 thereby confer a benefit thereto. Background of the Invention In laundry applications, silicone oils are commonly used in rinse conditioners formulation to 15 bring additional benefit to the consumer such as a better sensory, antiwrinkle properties and ease of ironing. Materials of this type reduce the level of wrinkling by lubricating the fabric fibres, thereby lowering the fibre friction thus assisting the fabric in recovering from its wrinkled state. Similarly, an ease of iron effect is obtained by reducing the friction between the sole of the iron and the fabric surface. The usual kind of silicone is a 20 polydimethyl siloxane (PDMS) or an aminosilicone, usually in emulsion form and is present at about 5% in the formulation. However, at present, it is difficult to deliver silicones from the main wash. A mere silicone emulsion, e.g. stabilized with a non-ionic/anionic surfactant system does 25 not show any deposition because of the lack of affinity of the silicone with the cotton surface. One way to improve the silicone uptake on the fabric is to emulsify with a cationic surfactant, as used in conventional rinse conditioner. In that case the positively charged silicone droplets interact with the mildly anionic cotton surface to form a coalesced film at the cotton surface. However, in main wash products cationic silicone emulsions cannot be 30 used because the cationic sites are immediately neutralized by the surrounding anionic surfactant, causing the emulsion to collapse. This results in the partial depletion of the available anionic surfactant and consequently in a decrease of the cleansing efficiency. WO 2004/056952 PCT/EP2003/013825- 2 Moreover, if any silicone deposits at all on the cotton, its distribution is extremely heterogeneous. The applicants have now found that certain silicone-containing graft or block cationic 5 copolymers, when used as delivery aids in a washing composition, produce silicone emulsions that remain stable in presence of anionic surfactant and lead to high silicone deposition efficiency on a washing process. Definition of the Invention 10 A first aspect of the present invention provides a laundry treatment composition comprising at least one polymeric material comprising a cationic polymer moiety and a polysiloxane moiety, and at least one other component. 15 A second aspect of the present invention provides a method for depositing a polymer onto a substrate, the method comprising, contacting in an aqueous medium, the substrate and a composition according to the first aspect of the invention. Detailed Description of the Invention 20 When deposited on a fabric substrate, especially cotton, the polymeric materials of the present invention can endow one or more benefits conventionally obtainable from silicone-type ingredients, such as one or more of fabric softening, anti-wrinkle, anti-fuzzing, anti-piling and easy ironing. 25 The Polymeric Material The polymeric material requires therein of a the polysiloxane moiety, a cationic polymer moiety and optionally, one or more other moieties such as neutral and/or anionic moieties. 30 The polymeric material is preferably chosen from those of formulae WO 2004/056952 PCT/EP2003/013825 3 (A-b-B)n-A (A-f)-B)n 5 A-g-(B)„ (A-r-B)n 10 (B-5-A)n B-g-(A)n wherein: A is a moiety that contains one or more cationic monomer units, preferably comprising 15 from 5% to 100% more preferably from 20% to 100%, still more preferably from 35% to 100% by weight of cationic monomer units, and preferably comprised of between 5 and 500,000 monomer units, the balance of A comprising from 0% to 95%, preferably from 0% to 30% by weight of anionic monomer units and/or from 0% to 95%, preferably from 0% to 70% by weight of neutral monomer units, wherein the weight fraction of A is preferably 20 from 5% to 95%, preferably from 60% to 95%, any balance being independently selected from one or more of anionic monomer units and/or cationic monomer units in block and/or random fashion.

Any anionic group forming part of an anionic monomer starting material or anionic monomer unit of the polymer may be in the acid form or salt form. Often, the free acid form 15 may be neutralised either as part of the process for forming the polymer or when the polymer is incorporated in the detergent composition. Suitable counter-cations of the salt forms are alkali metals such as sodium or potassium, alkaline earth metals such as magnesium or organic ions such as NH4+. 20 Synthetic Routes In the aforementioned general formulae, the moiety A can be obtained by any polymerization process, such as free radical polymerisation, ring opening polymerisation, 25 modification of natural pofymers such as polysaccharides, and polycondensations to name a few. In one embodiment, the polymeric material is prepared by free radical polymerization. There are several ways in which free radical polymerisation can be used. For example, for 30 polymerizing graft copolymers, there are several options, including using the "grafting from", "grafting onto" or "grafting through" approach. In the "grafting from" approach, the grafted chains are grown from the backbone onwards by e.g. creating grafting or initiating WO 2004/056952 PCT/EP2003/013825 14 sites on the backbone. With the "grafting onto" approach, the preformed pendant chains are reacted onto the backbone. The "grafting through" method occurs when a macromonomer is used and copolymerized with the monomers that compose the backbone polymer. The latter technique is preferred for the preferred structure A-g-(B)n. 5 In that case a preformed polydialkylsiloxane macromonomer B, having at one chain end a copofymerizable double bond, is polymerized together with the monomers constituting A. Block copolymers of the present invention can be prepared by several ways, such as chemical coupling of segments A and B through reactive groups located at the A and B 10 termini, or polymerization of the A block initiated from B terminus moiety. When the latter route is used, living free radical polymerization is one way to make the block copolymers of the present invention. One example of this type of process comprises: 15 a) activating the backbone B by attaching a control agent XY at one or both ends of B; b) carrying out a living (controlled) radical polymerization to grow the chain A from the initiating site XY; and c) optionally chemically modifying the polymer to bring the cationic sites on the A 20 blocks. In some embodiments, the copolymers of this invention are prepared, at least in part, using a living-type polymerization reaction. In these embodiments, for example, an initiator and, optionally, a control agent are combined with one or more preformed 25 macromonomers that comprise the B block. For block copolymers, the control agent is added to at least one derivatized terminus of the B block. For graft copolymers, the control agent can be added to derivitized portions of the backbone comprising the B moiety. The monomers that comprise the A block are then added to form a polymerization mixture, which is then subjected to or is under polymerization conditions causing a polymerization 30 reaction. The A block or graft (depending on the location of the control agent on the B moiety) is then grown to a desired point (e.g., molecular weight or degree of polymerization). WO 2004/056952 FC l/t-i'zuuj/ui ^»Z2 15 Ideally, the growth of the A block occurs with high conversion. Conversions are determined by NMR via integration of polymer to monomer signals. Conversions may also be determined by size exclusion chromatography (SEC) via integration of polymer to 5 monomer peak. For UV detection, the polymer response factor must be determined for each polymer/monomer polymerization mixture. Typical conversions can be 50% to 100 % for the A block, more specifically in the range of from about 60% to about 90%). Hawker et a/., "Development of a Universal Alkoxyamine for 'Living' Free Radical 10 Polymerizations," J. Am. Chem. Soc, 1999,121(16), pp. 3904-3920 discloses a*nitroxide mediated processes that may be used herein. Also, polymerization processes disclosed in U.S. Patent Application No. 09/520,583, filed March 8, 2000 and corresponding international application PCT/US00/06176 are particularly preferred, and both of these applications are incorporated herein by reference. 15 Generally, the polymerization proceeds under polymerization conditions. Polymerization conditions include the ratios of starting materials, temperature, pressure, atmosphere and reaction time. The polymerization conditions that may be used for nitroxide mediated living type free radical polymerization include: Temperatures for polymerization are typically in the 20 range of from about 80°C to about 130°C, more preferably in the range of from about 95°C to about 130°C and even more preferably in the range of from about 120°C to about 130°C. The atmosphere may be controlled, with an inert atmosphere being preferred, such as nitrogen or argon. The molecular weight of the polymer can be controlled via controlled free radical polymerization techniques or by controlling the ratio of monomer to initiator. 25 Generally, the ratio of monomer to initiator is in the range of from about 200 to about 800. In a nitroxide radical controlled polymerization the ratio of control agent to initiator can be in the range of from about 1 mol % to about 10 mol % is preferred. The polymerization may be carried out in bulk or in a suitable solvent such as diglyme. Polymerization reaction time may be in the range of from about 0.5 hours to about 72 hours, preferably from about 1 hour 30 to about 24 hours and more preferably from about 2 hours to about 12 hours. When radical additional fragmentation transfer (RAFT) living polymerization is implementeed, the polymerization conditions that may be used include temperatures for polymerization WO 2004/056952 PCT/EP2003/013825- 16 typically in the range of from about 20°C to about 110°C, more preferably in the range of from about 50°C to about 90°C and even more preferably in the range of from about 70°C to about 85°C. The atmosphere may be controlled; with an inert atmosphere being preferred, such as nitrogen or argon. The molecular weight of the polymer is controlled via adjusting 5 the ratio of monomer to control agent. When a RAFT-type technique is used, the control agent is defined as S .discussed below. Generally, with RAFT the ratio of monomer to control agent is in the range of from about 200 to about 800. A free radical initiator is usually added 10 to the reaction mixture, so as to maintain the polymerization rate to an acceptable level. Conversely, a too high free radical initiator to control agent ratio will favor unwanted dead polymer formation, namely pure homopoiymers or block copolymers of unknown composition. The molar ratio of free radical initiator to control agent for polymerization are typically in the range of from about 2:1 to about 0.02:1. 15 Initiators in the RAFT process that may be used are known in the art, and may be selected from the group consisting of alkyl peroxides, substituted alkyl peroxides, aryl peroxides, substituted aryl peroxides, acyl peroxides, alkyl hydroperoxides, substituted alkyl hydroperoxides, aryl hydroperoxides, substituted aryl hydroperoxides, heteroalkyl 20 peroxides, substituted heteroalkyl peroxides, heteroalkyl hydroperoxides, substituted heteroalkyl hydroperoxides, heteroaryl peroxides, substituted heteroaryl peroxides, heteroaryl hydroperoxides, substituted heteroaryl hydroperoxides, alkyl peresters, substituted alkyl peresters, aryl peresters, substituted aryl peresters, and azo compounds. Specific initiators include BPO and AlBN. The reaction media for these polymerization 25 reactions is either an organic solvent or bulk monomer or neat. Optionally, the dithio moiety of the control agent can be cleaved by chemical or thermal ways, if one wants to reduce the sulfur content of the polymer and prevent any problems associated with presence of the control agents chain ends, such as odor or discoloration. Typical chemical treatment include the catalytic or stochiometric addition of base such as a primary amine , 30 acid or anhydride, or oxydizing agents such as hypochloride salts. WO 2004/056952 PCT/EP2003/01382J 17 When living free radical polymerization is used , the RAFT process is one method that can be used, and more particularly RAFT processes using chain transfer agent of the dithio type, such as dithioesters, dithiocarbonates and dithiocarbamates, trithiocarbonates and 5 dithiocarbazates can be utilized. Typically, the agent must be able to be expelled as or support a free radical. In some embodiments, the control agent, Y, is characterized by the general formula: YS"R' S 10 where Z is any group that activates the C=S double bond towards a reversible free radical addition fragmentation reaction and R" is selected from the group consisting of, generally, any group that can be easily expelled under its free radical form (R'«) upon an addition-fragmentation reaction. This control agent can be attached to the B block through either Z or R", however, for ease these groups are discussed below in terms as if they are not the 15 linking group to the B block (thus, e.g., alkyl would actually be alkylene). R" is generally selected from the group consisting of optionally substituted hydrocarbyl, and heteroatom-containing hydrocarbyl. More specifically, R" is selected from the group consisting of optionally substituted alkyl, aryl, alkenyl, alkoxy, heterocyclyl, alkylthio, amino and polymer chains. And still more specifically, R" is selected from the group consisting of-CH2Ph, - 20 CH(CH3)C02CH2CH3, -CH(C02CH2CH3)2, -C(CH3)2CN, -CH(Ph)CN and -C(CH3)2Ph. Z is typically selected from the group consisting of hydrocarbyl, substituted hydrocarbyl, heteroatom-containing hydrocarbyl and substituted heteroatom containing hydrocarbyl. More specifically, Z is selected from the group consisting of optionally substituted alkyl, 25 aryl, heteroaryl and most preferably is selected from the group consisting of amino and alkoxy. In other embodiments, Z is attached to C=S through a carbon atom (dithioesters), a nitrogen atom (dithiocarbamate), two nitrogen atoms in series (dithiocarbazate), a sulfur 30 atom (trithiocarbonate) or an oxygen atom (dithiocarbonate). Specific examples for Z can WO 2004/056952 PCT/EP2003/013825 18 be found in WO 98/01478, W099/35177, W099/31144, W098/58974, U.S. Patent 6,153,705, and U.S. Patent Application No. 09/676,267, filed September 28, 2000, each of which is incorporated herein by reference. Particularly preferred control agents of the type in formula II are those where the control agent is attached through R" and Z is either, a 5 carbazate, -OCH2CH3 or pyrrole attached via the nitrogen atom. As discussed below, linker molecules can be present to attach the C=S group to the B block through Z or R". One possible route to silicone block copolymers of the invention is to chemically link a mono end functional polydimethylsiloxane (PDMS) with the R group of the CTA .- This can 10 be done for instance by first derivatizing the R group with an electrophile such as? isocyanate, epoxy of acid chloride, and coupling with the PDMS block bearing a nucleophile at its one terminus, the latter being an amine or an alcohol group. The PDMS -CTA adduct is then subjected to living free radical polymerization to extend the chain with a cationic copolymers, by insertion of the monomer units between the PDMS and the CTA 15 moiety. Optionaly the dithio group is then disposed of by chemical or thermal cleavage. In other embodiments an initiator-control agent adduct is used. The control agent may be a nitroxide radical. Broadly, the nitroxide radical control agent may be characterized by the general formula -0-NR5R6, wherein each of R5 and R6 is independently selected from 20 the group of hydrocarbyl, substituted hydrocarbyl, heteroatom containing hydrocarbyl and substituted heteroatom containing hydrocarbyl; and optionally Rs and R6 are joined together in a ring structure. In a more specific embodiment, the control agent may be characterized by the general formula: 25 where I is a residue capable of initiating a free radical polymerization upon homolytic cleavage of the l-O bond, the I residue being selected from the group consisting of fragments derived from a free radical initiator, alkyl, substituted alkyl, alkoxy, substituted alkoxy, aryl, substituted aryl, and combinations thereof; X is a moiety that is capable of destabilizing the control agent on a polymerization time scale; and each R1 and R2, WO 2004/056952 PCT/EP2003/013825 19 independently, is selected from the group consisting of alkyl, substituted alkyl, cycioalkyl, substituted cycioalkyl, heteroalkyl, heterocycloalkyl, substituted heterocycloalkyl, aryl, substituted aryl, heteroaryl, substituted heteroaryl, alkoxy, aryloxy, silyl, boryl, phosphino, amino, thio, seleno, and combinations thereof; and R3 is selected from the group 5 consisting of tertiary alkyl, substituted tertiary alkyl, aryl, substituted aryl, tertiary cycioalkyl, substituted tertiary cycioalkyl, tertiary heteroalkyl, tertiary heterocycloalkyl, substituted tertiary heterocycloalkyl, heteroaryl, substituted heteroaryl, alkoxy, aryloxy and silyl. Preferably, X is hydrogen. 10 Synthesis of the types of initiator-control agents in the above formula is disclosed in, for example, Hawker et a/., "Development of a Universal Alkoxyamine for 'Living' Free Radical Polymerizations," J. Am. Chem. Soc, 1999, 121(16), pp. 3904-3920 and U.S. Patent Application No. 09/520,583, filed March 8, 2000 and corresponding international application PCT/USOO/06176, all of which are incorporated herein by reference. 15 The polymers of the invention can be either soluble or dispersible in water. The solubility of the polymer can also be aided by the addition of surface active materials: for instance non-ionic surfactants are useful to solubilize (co-micellize) the block and graft copolymers of the invention, as well as to provide a good compatibility of said polymers with washing 20 formulations containing anionic surfactants. Solubilisation is also facilited with the use of high shear homogeneizers. Compositions 25 The polymeric material is incorporated together with one or more other components into laundry treatment compositions. For example, such a composition may optionally also comprise only a diluent (which may comprise solid and/or liquid) and/or also it may comprise an active ingredient The polymeric material is typically included in said 30 compositions at levels of from 0.001 % to 10% by weight, preferably from 0.025% to 5%, more preferably from 0.01% to 3%. However, as will be explained in more detail herein below, the polymeric material may be incorporated in the form of a silicone emulsion. WO 2004/056952 PCT/EP2003/01382S 20 The active ingredient in the compositions is preferably a surface active agent or a fabric conditioning agent. More than one active ingredient may be included. For some applications a mixture of active ingredients may be used. Although the compositions of 5 the invention are preferably wash compositions, especially those containing anionic surfactant, rinse compositions are not excluded. The compositions of the invention may be in any physical form e.g. a solid such as a powder or granules, a tablet, a solid bar, a paste, gel or liquid, especially, an aqueous 10 based liquid. In particular the compositions may be used in laundry compositions, especially in liquid, powder or tablet laundry composition. The compositions of the present invention are preferably laundry compositions, especially main wash (fabric washing) compositions or rinse-added softening compositions. The main wash compositions may include a fabric softening agent and rinse-added fabric softening 15 compositions may include surface-active compounds, particularly non-ionic surface-active compounds, if appropriate. Emulsions 20 The polymers of the invention are either soluble or dispersible in water. The solubility of the polymer can also be aided by the addition of surface active materials: for instance non-ionic surfactants are useful to solubilize (co-micellize) the block and graft copolymers of the invention, as well as to provide a good compatibility of said polymers with washing formulations containing anionic surfactants. Solubilization is also facilited with the use of 25 high shear homogeneizers. These materials prove to be efficient in dispersing polysiloxane oils as stable emulsions, said emulsions being compatible (i.e not showing any signs of coagulation) with washing liquors. These polymers also demonstrate unexpectedly good silicone oil deposition 30 efficiency on cotton fabric, under washing conditions. WO 2004/056952 PCT/EP2003/013825 21 Therefore the polymeric material may be provided in the form of an emulsion with a silicone, for use in laundry treatment compositions. The emulsion must contain another liquid component as well as the silicone, preferably a 5 polar solvent, such as water. The emulsion has typically 30 to 99.9%, preferably 40 to 99% of the other liquid component (eg water). Low water emulsions may be for example 30 to 60% water, preferably 40 to 55% water.

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. The emulsifying agent most preferably comprises or 15 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 emulsifiying agent. 20 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 average in the hydrocarbon chain thereof and preferably on average from 3 to 11, more preferably from 4 to 9 alkyleneoxy groups.

Preferably, the (po!y)alkoxyiated analogues of saturated or unsaturated fatty alcohols, have a hydrophilic-lipophilic balance (HLB) of between 8 to 18. The HLB of a 30 polyethoxylated primary alcohol nonionic surfactant can be calculated by WO 2004/056952 PCT/EP2003/013825. 22 HLB= MW(EO) x 100 MW(TOT) x 5 5 where MW (EO) = the molecular weight of the hydrophilic part (based on the awerage number of EO groups) 10 MW(TOT) = the molecular weight of the whole surfactant (based on the average 6hain length of the hydrocarbon chain) This is the classical HLB calculation according to Griffin (J. Soc. Cosmentic Chemists, 5 (1954)249-256). 15 For analogous nonionics with a mix of ethyleneoxy (EO), propylenoxy (PO) and/or butyleneoxy (BO) hydrophilic groups, the following formula can be used; 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 in which R is a linear or branched, saturated or unsaturated aliphatic alkyl radical having 8 30 to 18 carbon atoms or mixtures thereof, and Zn is a polyglycosyl radical with n=1.0 to 1.4 hexose or pentose units or mixtures.

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 30 also be in compact form which means it will contain a lower level of water compared to a conventional liquid detergent.

(2) Diblock and triblock copolymers by RAFT-polymerization These polymers are prepared by RAFT radical polymerization of the following initial blocks with a control transfer agent (CTA) at one chain end or both chain ends and 15 monomers: Synthesis of Control Transfer Agent (CTA) and its attachment to hydroxy- or amino functionalized Polydimethylsiloxanes: Sold pyrazole (50 mmol) was administered to a suspension of sodium hydroxide (50 mmol) in 20 mL DMSO under nitrogen atmosphere 20 and after 20 min stirring at room temperature (ca. 20°C), carbon disulfide (50 mmol) was added dropwise over a period of 1 min followed by 30 min stirring. Then, the reaction was treated with 2-hydroxyethyl 2-bromo-propionate (50 mmol). The resulting reaction mixture was stirred for 12 hours and quenched with 200 mL ice/water. After 5 min stirring, the reaction was extracted with ethyl ether (3 x 100 mL), the combined organic phases were 25 dried over MgS04, filtered, and concentrated (ca. 20°C/20 torr). The residue was purfied by silica-gel chromatography (CH2CI2) to yield the hydroxy-functionalized CTA as yellow oil (60% yield, unoptimized). The hydroxy-CTA (10 mmol) was dissolved in 50 mL CH2CI2 and added to a solution of 1,4-diisocyanate-hexane (50 mmol) in 30 mL CH2CI2 followed by the catalytic addition of dibutyltin dilaurate (0.1 mmol). After 1 hour stirring, the solvent was 30 stripped at room temperature under vacuum and the residue was washes with hexane (3 x 50 mL) to yield the control agent attached to one end of the linker, referred to as "control transfer agent-linker", as yellow oil. Coupling of the CTA-iinker with the amino- or hydroxy- WO 2004/056952 PCT/EP2003/013825^ 46 terminated polydimethylsiloxanes was performed by direct treatment of amino- or hydroxy-PDMS with the desired mol equivalents of CTA-linker in CH2CL2 with stirring for a minimum period of time of 30 min. For the amino-polydimethylsiloxanes the reaction was achieved without further catalysis while for the hydroxy-polydimethylsiloxanes the catalytic addition of dibutyltin dilaurate was required to obtain the coupling.

The polymerization mixture was heated under argon at 65°C for 15 hrs, then cooled to room temperature. Methyl iodide was added to quaternize the tertiary amino groups (2 equivalent WO 2004/056952 PCT/EP2003/013825 47 per tertiary amino group), and the reaction mixture was allowed to stand at room temperature for 12 hrs. Polymer was isolated by evaporation of the solvent under vacuum. The reaction was carried out in a parallel 96 reactor format with 1 mL glass vials using the combinatorial platform developed at Symyx. 5 Testing results on for these block copolymers are showed in Table 4. Silicone emulsion preparation: (1) Emulsification by sonication 10 30mg of silicone oil (Dow Corning) 3mg of polymer and 3ml_ of a non-ionic co-surfactant solution (0.02 wt.% in de-ionized water) were mixed in a 8mL glass vial, and the mixture is then sonicated with a sonication probe to form an emulsion. (2) Emulsification by phase inversion Silicone oil (2.0g) and co-surfactant (120mg) were mixed in a 40-mL scintillation vial, and 15 stirred with an Ultra-Turrax as a solution of polymer (0.2g) in water (4.0mL) was added slowly, followed by addition of water (10mL). The emulsion was then transferred to a kitchen blender, and stirred for 10min while water (184mL) was added. Washing procedure and silicone deposition efficiency measurement: 20 CH Small Scale Washing In a BmL glass vial, silicone emulsion (0.3mL) and model washing liquor (2.7mL) were mixed to give a silicone concentration of 1000mg/L, and two piece of cotton fabric (150mg each) were added. The glass vial was gently shaken at ambient temperature for 1 hour. 25 The cotton samples were then rinsed with de-ionized water and dried.. The silicone adsorbed on the fabric was extracted by toluene and quantified by GPC. The deposition efficiency (DE) was calculated as the ratio of the extracted to the initial silicone in %. (2) Model Washing In a 550ml_ steel washpot, silicone emulsion and model washing liquor were mixed to give 30 a silicone concentration of 250mg/L, and one piece of cotton fabric (fabric/wash ratio = 1/8) was added. The washpot was sealed and placed in a Washtec-p machine, and the washing was conducted at 40°C for 45min. The cotton samples were then rinsed with de- WO 2004/056952 PCT/EP2003/013825. 48 ionized water and dried. The silicone adsorbed on the fabric was extracted by toluene and quantified by GPC. The deposition efficiency (DE) was calculated as the ratio of the extracted to the initial silicone in %. 5 Model Wash Formulation: Anionic surfactant (LAS) 0.55g/L Non-ionic surfactant R(EO)7 0.45g/L Trisodium citrate 0.175g/L 10 Sodium carbonate 0.29g/L Sodium bicarbonate 0.05g/L Sodium sulphate 1.10g/L 15 Results Polymers 1-131 are silicone emulsions prepared with silicone oil of viscosity 350cSt by sonication, and small scale washing procedure was used for washing. Under small scale washing conditions, the blank experiments (silicone emulsion without polymers) give 20 deposition efficiency of less than 14%. In examples 132-143, all silicone emulsions were prepared with silicone oil of viscosity 350cSt by sonication, and in selected examples (133,136,137 and 140), emulsions were also prepared by phase inversion. The large scale washing procedure was used for washing, and under these conditions, the control experiments give deposition efficiency of 19% (when emulsion prepared by sonication) 25 and 16% (when emulsion prepared by phase inversion). In examples 144-149, silicone emulsions were prepared with silicone oil of viscosity 100cSt by sonication, and primary screening procedure was used for washing. Under these conditions, the blank experiments give deposition efficiency of 5%. From these results, it becomes clear that these random or block copolymers increase the silicone deposition on cotton fabric, when compared to 30 the blank experiments.
