Abstract: The present invention relates to a process for pretreating soiled fabrics with a liquid composition comprising a peroxygen bleach and a soil dispersing agent selected from the group consisting of an ethoxylated monoamine, an ethoxylated diamine, an ethoxylated polyamine, an ethoxylated amine polymer and mixtures thereof. This invention also discloses liquid compositions suitable for pretreating fabrics, comprising a peroxygen bleach, a surfactant, and a soil dispersing agent selected from the group consisting of an ethoxylated monoamine, an ethoxylated diamine, an ethoxylated polyamine, an ethoxylated amine polymer and mixtures thereof, said composition being formulated either as an emulsion or a microemulsion.

Description: Technical field The present invention relates to bleaching compositions particularly suitable to be used as a pretreater and to a process of pretreating fabrics. Background A great variety of cleaning compositions have been described in the art, that are particularly suitable for pretreating fabrics. For instance, EP-A-598170 discloses a particular type of cleaning compositions which are aqueous emulsions of a nonionic surfactant system further comprising hydrogen peroxide or water-soluble source thereof and a liquid bleach activator, or any other hydrophobic ingredient which needs to be separated from said hydrogen peroxide. EP-A-0 735 133 (relevant for novelty only) discloses a particular type of cleaning compositions which are aqueous microemulsions of a bleach activator in a matrix comprising water, hydrogen peroxide and a hydrophilic surfactant system. However, a drawback associated with such emulsions or microemulsions comprising a peroxygen bleach and a bleach activator, especially when used in laundry pretreatment applications on different kinds of fabrics, e.g., cotton and/or synthetic fabrics (e.g., polyester/polyamides), is that they do not deliver effective performance which satisfactorily meet consumer's needs on all types of stains including greasy stains, enzymatic stains, mud/clay stains as well as bleachable stains. Indeed, there is still some room to further improve the stain removal performance as well as the bleaching performance of such bleach-containing compositions when pretreating a fabric therewith. It is thus an object of the present invention to provide improved stain removal performance on a wide range of stains as well as improved bleaching performance, especially under laundry pretreatment conditions, i.e., when applied neat onto at least a portion of a fabric before washing said fabric. Furthermore, another problem associated with such emulsions and/or microemulsions especially with those containing relatively high concentration of surfactants, e.g., about 8 % or above, is that important viscosity tends to build up, which makes said emulsions/microemulsions difficult to dispense, and thus unacceptable from a consumer viewpoint. It is thus a further object of the present invention to provide liquid emulsions or microemulsions comprising a peroxygen bleach and a surfactant wherein the viscosity can be conveniently controlled while maintaining adequate physical stability. It has now been found that improved stain removal performance is obtained, by using a liquid composition comprising a peroxygen bleach and a soil dispersing agent selected from the group consisting of an ethoxylated monoamine, an ethoxylated diamine, an ethoxylated polyamine, an ethoxylated amine polymer and mixture thereof, as described hereinafter, to pretreat soiled fabrics. Indeed, the addition of such a soil dispersing agent, in a liquid composition comprising a peroxygen bleach, and optionally a bleach activator, delivers improved stain removal performance on various types of stains including greasy stains, enzymatic stains, clay/mud stains, and the like, under pretreatment conditions, as compared to the stain removal performance delivered by the same composition without said soil dispersing agent. Also, it has surprisingly been found that the liquid compositions comprising both the peroxygen bleach and said soil dispersing agent, when used to pretreat fabrics, provide improved bleaching efficacy, as compared to the same compositions without said soil dispersing agent. Thus, it has been found that the addition of a single compound, i.e., such a soil dispersing agent, in a peroxygen bleach-containing composition, delivers both improved stain removal performance and improved bleaching performance. Furthermore, it has been found that this improved stain removal performance on various stains is maintained even for peroxygen bleach-containing compositions having undergone long storage time. It is thus speculated that the oxidized form of the soil suspeding agent that may have formed in the presence of a peroxygen bleach under long storage time and/or elevated temperature still provides improved stain removal performance on various types of stains. Thus, in its broadest aspect, the present invention encompasses a process for bleaching a fabric with a liquid composition comprising from 0.01% to 15% by weight of the total composition of a peroxygen bleach, and a soil dispersing agent, said process comprising the steps of applying said liquid composition in its neat form onto at least one portion of said fabric, optionally allowing said composition to remain in contact with said fabric and then washing said fabric. Furthermore, it has been found that the addition of a soil dispersing agent selected from the group consisting of an ethoxylated monoamine, an ethoxylated diamine, an ethoxylated polyamine, an ethoxylated amine polymer and mixture thereof, in a liquid composition formulated either as an emulsion or microemulsion, comprising a peroxygen bleach and a surfactant, reduces the viscosity of said composition, whatever the viscosity was before the addition of said soil dispersing agent. Actually, an advantage of the liquid compositions of the present invention formulated either as an emulsion or a microemulsion, is that they deliver improved stain removal performance and improved bleaching performance while delivering acceptable viscosity, without the need to add viscosity control agents. In other words, the present invention allows to formulate emulsions or microemulsions with improved overall stain removal/bleaching performance and desirable physical characteristics at reduced costs, i.e., without adding any viscosity control agent that would raise the cost formula and bulk to the compositions without contributing to the bleaching/cleaning performance of said compositions. Another advantage of the present invention is that stable liquid emulsions or microemulsions are provided that are suitable to be used in the most efficient manner by the consumer over prolonged period of time. Yet another advantage of the compositions according to the present invention which are formulated as emulsions or microemulsions is that they provide also excellent cleaning and/or bleaching performance when used in applications other than laundry pretreaters, such as in other laundry applications, as laundry detergents or laundry additives. EP-A-0 754 214 (relevant for nevalty only) discloses laundry compositions suitable for pretreating fabrics comprising polyamines and peroxygen bleach. No ethoxylated amines, ethoxylated polyamines or ethoxylated amine polymers are disclosed. US 5,759,439 discloses pretreater compositions with particular chelants, a peroxygen bleach, and optional ingredients like bleach activators, polymeric soil releasing agents like sulfonated poly-ethoxy/propoxy end-capped ester oligomer. However, no ethoxylated amines, ethoxylated polyamines, or ethoxylated amine polymers are disclosed. EP-A-271 312 discloses laundry compositions comprising a peroxyacid bleach and a soil release agent like particular alkyl and hydroxyalkyl ethers of cellulose, polymers comprising ethylene terephthalate and polyethylene oxide terephthalate. No ethoxylated amines, ethoxylated polyamines or ethoxylated amine polymers are disclosed. WO96/12004 discloses laundry compositions comprising a lipophilic enzyme and a primary and/or tertiary amine. These compositions provide enhanced cleaning of greasy/oily soils and stains, particularly when used in pretreatment laundering process for cleaning fabrics stained with greasy soils. The compositions exemplified comprise tetraethylenepentamine ethoxylated (15-18) but no bleach. EP-A- 112 593 discloses detergent compositions (pH= 6 to 8.5) comprising ethoxylated mono- or diamines, ethoxylated polyamines and/or ethoxylated amine polymers as a clay soil removal/antiredeposition agent. Said compositions may be used in laundry pretreatment application. No peroxygen bleaches are disclosed. Summary of the invention The present invention encompasses a process of bleaching a fabric with a liquid composition comprising from 2% to 15% by weight of the total composition of a peroxygen bleach, and a soil dispersing agent selected from the group consisting of (1) ethoxylated monoamines having the formula: (X―L―)―N―(R 2 ) 2 (2) ethoxylated diamines having the formula: or (X - L - ) 2 - N - R 1 - N - (R 2 ) 2 (3) ethoxylated polyamines having the formula: (4) ethoxylated amine polymers having the general formula: and (5) mixtures thereof, wherein R is H or C 1 -C 4 alkyl or hydroxyalkyl; R1 is C 2 -C 12 alkylene, hydroxyalkylene, alkenylene, arylene or alkarylene, or a C 2 -C 3 oxyalkylene moiety having from 2 to 20 oxyalkylene units provided that no O ― N bonds are formed; each R 2 is C 1 -C 4 alkyl or hydroxyalkyl, the moiety ― L ― X, or two R 2 together form the moiety ― (CH 2 ) r ― A 2 ― (CH 2 ) s ―, wherein A 2 is ― O ― or ― CH 2 ―, r is 1 or 2, s is 1 or 2, and r+s is 3 or 4; X is a nonionic group, an anionic group or mixture thereof; R 3 is substituted C 3 -C 12 alkyl, hydroxyalkyl, alkenyl, aryl, or alkaryl group having p substitution sites; R 4 is C 1 -C 12 alkylene, hydroxyalkylene, alkenylene, arylene or alkarylene, or a C 2 -C 3 oxyalkylene moiety have from 2 to 20 oxyalkylene units provided that no O ― O or O ― N bonds are formed; L is a hydrophilic chain which contains the polyoxyalkylene moiety ―[(R 5 O) m (CH 2 CH 2 O) n ]―, wherein R 5 is C 3 -C 4 alkylene or hydroxyalkylene and m and n are numbers such that the moiety ―(CH 2 CH 2 O) n ― comprises at least 50% by weight of said polyoxyalkylene moiety; for said monoamines, m is from 0 to 4, and n is at least 12; for said diamines, m is from 0 to 3, and n is at least 6 when R 1 is C 2 -C 3 alkylene hydroxyalkylene, or alkenylene, and at least 3 when R 1 is other than C 2 -C 3 alkylene, hydroxyalkylene or alkenylene; for said polyamines and amine polymers, m is from 0 to 10 and n is at least 3; p is from 3 to 8; q is 1 or 0; t is 1 or 0, provided that t is 1 when q is 1; w is 1 or 0 ; x + y + z is at least 2; and y + z is at least 2, said process comprising the steps of applying said composition in its neat form onto at least a portion of said fabric, before said fabric is washed. The present invention encompasses a liquid composition suitable for pretreating fabrics, comprising from 2% to 15% by weight of the total composition of a peroxygen bleach, a surfactant and a soil dispersing agent selected from the group consisting of an ethoxylated monoamine, an ethoxylated diamine, an ethoxylated polyamine, an ethoxylated amine polymers and mixture thereof as previously defined, said composition being formulated either as an emulsion or a microemulsion. Detailed description of the invention The laundry pretreatment process In its broadest embodiment, the present invention relates to a process of pretreating a fabric with a liquid composition comprising a soil dispersing agent, as defined herein, and from 2% to 15% by weight of the total composition of a peroxygen bleach. By "pretreating a fabric" it is to be understood that the liquid composition herein is applied in its neat form onto at least a portion of a soiled fabric, optionally left to act onto said fabric typically for a period of time of 1 minute to several hours, before said fabric is washed, as described hereinafter, in the process of bleaching fabrics according to the present invention. Indeed, the present invention is based on the finding that by adding a soil dispersing agent, as described herein, in a liquid composition comprising a peroxygen bleach, improved stain removal performance is obtained with said composition when used to pretreat a soiled fabric before said fabric is washed, as compared to the stain removal performance delivered with the same composition without said soil dispersing agent. By "stain removal performance" it is meant herein stain removal performance on a variety of stains/soils such as greasyloily stains, and/or enzymatic stains and/or mud/clay stains as well as bleachable stains. By "greasy/oily stains" it is meant herein any soil and stain of greasy nature that can be found on a fabric like dirty motor oil, mineral oil, make-up, lipstick vegetal oil, spaghetti sauce, mayonnaise and the like. Examples of bleachable stains include tea, coffee, wine and the like. Examples of enzymatic stains include grass, chocolate and blood. The stain removal performance of a given composition on a soiled fabric under pretreatment conditions, may be evaluated by the following test method. A composition according to the present invention is first applied to the stained portion of said fabric, left to act from about 1 to about 10 minutes, typically 5 minutes, and said pretreated fabric is then washed according to common washing conditions with a conventional detergent composition, at a temperature of from 30°C to 70°C for a period of time sufficient to bleach said fabric. For example, typical soiled fabrics to be used in this stain removal performance test method may be commercially available from EMC (Empirical Manufacturing Company) Cincinnati, Ohio, USA such as clay, chocolate, spaghetti sauce, dirty motor oil, make-up, tea, coffee, blood on two different substrate/fabric, e.g., cotton (CW120) and polycotton (PCW28). The stain removal performance may then be evaluated by comparing side by side the soiled fabric pretreated with the composition according to the present invention with those pretreated with the reference, e.g., the same composition without such a soil dispersing agent according to the present invention. A visual grading scale may be used to assign differences in panel score units (psu), in a range from 0 to 4. Accordingly, the present invention encompasses a process of bleaching a fabric with a liquid composition comprising from 2% to 15% by weight of the total composition of a peroxygen bleach and a soil dispersing agent, as defined herein, said process comprises the steps of applying said composition in its neat form onto at least a portion of said fabric, optionally allowing said composition to remain in contact with said fabric preferably without leaving said composition to dry onto said fabric, before said fabric is washed. Said composition may remain in contact with said fabric, typically for a period of 1 minute to several hours, preferably 1 minute to 1 hour, more preferably 1 minute to 30 minutes, and most preferably 2 to 10 minutes. Optionally, when the fabric is soiled with encrusted stains/soils which otherwise would be relatively difficult to remove, said composition may be rubbed and/or brushed more or less intensively, for example, by means of a sponge or a brush or simply by rubbing two pieces of fabric each against the other. By "washing" it is to be understood herein to simply rinse the fabric with water, or the fabric may be washed with a conventional composition comprising at least one surface active agent, this by the means of a washing machine or simply by hand. By "in its neat form" it is to be understood that the liquid compositions are applied directly onto the fabrics to be pre-treated without undergoing any dilution, e.g., the liquid compositions according to the present invention are applied as described herein. According to the process of pretreating soiled fabrics of the present invention, the liquid compositions used in said process should preferably not be left to dry onto the fabrics. Indeed, it has been found that water evaporation contributes to increase the concentration of free radicals onto the surface of the fabrics and, consequently, the rate of chain reaction. It is also speculated that an auto-oxidation reaction occurs upon evaporation of water when the liquid compositions are left to dry onto the fabrics. Said reaction of auto-oxidation contributes to generate peroxy-radicals which may cause color damage and/or fabric damage. Thus, not leaving the liquid bleaching compositions used according to the present invention to dry onto the fabrics, in the process of bleaching fabrics according to the present invention would result in a safer pretreating operation with liquid bleaching compositions. As an essential element the compositions to be used according to the present invention comprise a peroxygen bleach or mixtures thereof. The peroxygen bleach to be used herein is any peroxygen bleach, known to those skilled in the art. Such peroxygen bleach includes hydrogen peroxide, or a water-soluble source thereof, or mixtures thereof. Indeed, the presence of the peroxygen bleach contributes to the excellent cleaning and bleaching benefits of the compositions used according to the present invention. As used herein a hydrogen peroxide source refers to any compound which produces perhydroxyl ions when said compound is in contact with water. Suitable water-soluble sources of hydrogen peroxide for use herein include percarbonates, persilicate, persulphate such as monopersulfate, perborates, peroxyacids such as diperoxydodecandioic acid (DPDA), magnesium perphtalic acid, perlauric acid, perbenzoic and alkylperbenzoic acids, hydroperoxides, diacyl peroxides and mixtures thereof. Preferred peroxygen bleaches used herein are hydrogen peroxide, hydroperoxide and/or aliphatic diacyl peroxide. Suitable hydroperoxides for use herein are tert-butyl hydroperoxide, cumyl hydroperoxide, 2,4,4-trimethylpentyl-2-hydroperoxide, di-isopropylbenzene-monohydroperoxide, tert-amyl hydroperoxide and 2,5-dimethyl-hexane-2,5-dihydroperoxide. Such hydroperoxides have the advantage to be particularly safe to fabrics and color while delivering excellent bleaching performance. Suitable aliphatic diacyl peroxides for use herein are dilauroyl peroxide, didecanoyl peroxide, dimyristoyl peroxide or mixtures thereof. Such aliphatic diacyl peroxides have the advantage to be particularly safe to fabrics and color while delivering excellent bleaching performance. The compositions used according to the present invention comprise from 2% to 15% by weight of the total composition of such a peroxygen bleach or mixtures thereof, preferably from 2% to 12%, more preferably from 2% to 10% and most preferably from 2% to 8%. As an essential element the compositions to be used according to the present invention comprise a soil dispersing agent selected from the group consisting of ethoxylated monoamines, ethoxylated diamines, ethoxylated polyamines, ethoxylated amine polymers, as previously defined and mixtures thereof. Indeed, the presence of said soil dispersing agent contributes to the excellent cleaning and bleaching benefits of the compositions used according to the present invention. In the preceding formulas of the soil dispersing agent used herein, R 1 can be branched or most preferably linear alkylene, hydroxyalkylene, alkenylene, alkarylene or oxyalkylene. R 1 is preferably C 2 -C 6 alkylene for the ethoxylated diamines and amine polymers. For the ethoxylated diamines, the minimum degree of ethoxylation required for suitable soil removal/anti-redeposition properties decreases on going from C 2 -C 3 alkylene (ethylene, propylene) to hexamethylene. However, for the ethoxylated amine polymers, in particular the ethoxylated polyalkyleneamines and polyalkyleneimines, especially at higher molecular weights, C 2 -C 3 alkylene (ethylene, propylene) are preferred for R 1 with ethylene being most preferred. Each R 2 is preferably the moiety ― L ― X. In the preceding formulas, hydrophilic chain L usually consists entirely of the polyoxyalkylene moiety ―[(R 5 O) m (CH 2 CH 2- O) n ]―. The moieties ―(R 5 O) m ― and ―(CH 2 CH 2 O) n ― of the polyoxyalkylene moiety can be mixed together or preferably form blocks of ―(R 5 O) m ― and ―(CH 2 CH 2 O) n ― moieties. R 5 is preferably C 3 H 6 (propylene). For the ethoxylated polyamines and amine polymers, m is preferably from 0 to 5. For all ethoxylated amines of the present invention, m is most preferably 0, i.e. the polyoxyalkylene moiety consists entirely of the moiety ―(CH 2 CH 2 O) n ―. The moiety ―(CH 2 CH 2 O) n ― preferably comprises at least 85% by weight of the polyoxyalkylene moiety and most preferably 100% by weight (m is O). In the preceding formula, X can be any compatible nonionic group, anionic group or mixture thereof. Suitable nonionic groups include C 1 -C 4 alkyl or hydroxyalkyl ester or ether groups, preferably acetate or methyl ether, respectively; hydrogen (H); or mixtures thereof. The particularly preferred nonionic group is H. With regard to anionic groups, PO 3 -2 and SO 3 - are suitable. The particularly preferred anionic group is SO 3 - . It has been found that the percentage of anionic groups relative to nonionic groups can be important to the soil removal/anti-redeposition properties provided by the ethoxylated amine. A mixture of from 0 to 30% anionic groups and from 70 to 100% nonionic groups provides preferred properties. A mixture of from 5 to 10% anionic groups and from 90 to 95% nonionic groups provides the most preferred properties. Usually, a mixture of from 0 to 80% anionic groups and from 20 to 100% nonionic groups provides suitable soil removal/anti-redeposition properties. Preferred ethoxylated mono- and diamines have the formula: wherein X and n are defined as before, a is 0 or 1 and b is from 0 to 4. For preferred ethoxylated monoamines (a=0), n is at least 15, with a typical range of from 15 to 35. For preferred ethoxylated diamines (a=1), n is at least 12 with a typical range of from 12 to 42. Methods for making ethoxylated amines are for example described in EP-A-112 593. In the preceding formula for the ethoxylated polyamines, R 3 (linear, branched, or cyclic) is preferably a substituted C 3 -C 6 alkyl, hydroxyalkyl or aryl group; A 1 is preferably n is preferably at least 12, with a typical range of from 12 to 42; p is preferably from 3 to 6. When R 3 is a substituted aryl or alkaryl group, q is preferably 1 and R 4 is preferably C 2 -C 3 alkylene. When R 3 is an alkyl, hydroxyalkyl, or alkenyl group, and when q is 0, R 1 is preferably a C 2 -C 3 oxyalkylene moiety; when q is 1, R 4 is preferably C 2 -C 3 alkylene. These ethoxylated polyamines can be derived from polyamino amides such as: These ethoxylated polyamines can also be derived from polyaminopropylene-oxide derivatives such as: wherein each c is a number from 2 to 20. Preferred ethoxylated amine polymers are the ethoxylated C 2 -C 3 polyalkyleneamines and polyalkyleneimines Particularly preferred ethoxylated polyalkyleneamines and polyalkyleneimines are the ethoxylated polyethyleneamines (PEA's) and polyethyleneimines (PEI's). These preferred compounds comprise units having the general formula: wherein X, w, x, y, z and n are defined as before. Prior to ethoxylation, the PEAs used in preparing compounds of the present invention have the following general formula: wherein x + y + z is from 2 to 9, y + z is from 2 to 9 and w is 0 or 1 (molecular weight of from 100 to 400). Each hydrogen atom attached to each nitrogen atom represents an active site for subsequent ethoxylation. For preferred PEAs, y + z is from 3 to 7 (molecular weight of from 140 to 310) and most prefarably from 3 to 4 (molecular weight of from 140 to 200). These PEA's can be obtained by reactions involving ammonia and ethylene dichloride, followed by fractional distillation. The common PEA's obtained are triethylenetetramine (TETA) and tetraethylenepentamine (TEPA). Above the pentamines, i.e., the hexamines, heptamines, octamines and possibly nonamines, the cogenerically derived mixture does not appear to separate by distillation and can include other materials such as cyclic amines and particularly piperazines. There can also be present cyclic amines with side chains in which nitrogen atoms appear. See US Patent 2,792,372 to Dickson, issued May 14, 1957, which describes the preparation of PEAs. The minimum degree of ethoxylation required for preferred soil removal/anti-redeposition performance can vary depending upon the number of units in the PEA. Where y + z is 2 or 3, n is preferably at least about 6. Where y + z is from 4 to 9, suitable benefits are achieved when n is at least 3. For most preferred ethoxylated PEAs, n is at least 12, with a typical range of from 12 to 42. The PEIs used in preparing the compounds of the present invention have a molecular weight of at least 440 prior to ethoxylation, which represents at least 10 units. Preferred PEls used in preparing these compounds have a molecular weight of from 600 to 1800. The polymer backbone of these PEIs can be represented by the general formula: wherein the sum of x, y, and z represents a number of sufficient magnitude to yield a polymer having the molecular weights previously specified. Although linear polymer backbones are possible, branch chains can also occur. The relative proportions of primary, secondary and tertiary amine groups present in the polymer can vary, depending on the manner of preparation. The distribution of amine groups is typically as follows: Each hydrogen atom attached to each nitrogen atom of the PEI represents an active site for subsequent ethoxylation. These PEIs 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 or acetic acid. Specific methods for preparing PEIs are disclosed in U.S. Patent 2,182,306 to Ulrich et al., issued December 5, 1939; U.S. Patent 3,033,746 to Mayle et al., issued May 8, 1962; US Patent 2,208,095 to Esselmann et al., issued July 16, 1940; US Patent 2,806,839 to Crowther, issued Sept. 17, 1957; and US Patent. 2,553,696 to Wilson, issued May 21, 1951. As defined in the preceding formulas, n is at least 3 for the ethoxylated PEIs. However, it should be noted that the minimum degree of ethoxylation required for suitable soil removal/anti-redeposition performance can increase as the molecular weight of the PEI increases, especially much beyond 1800. Also, the degree of ethoxylation for preferred compounds increases as the molecular weight of the PEI increases. For PEIs having a molecular weight of at least 600, n is preferably at least 12, with a typical range of from 12 to 42. For PEIs having a molecular weight of at least 1800, n is preferably at least 24, with a typical range of from 24 to 42. Typically, the compositions used according to the present invention comprise from 0.01% to 20% by weight of the total composition of such a soil dispersing agent or mixtures thereof, preferably from 0.1% to 10%, more preferably 0.2% to 4% and most preferably from 0.5% to 2%. The liquid compositions used according to the process of the present invention are preferably aqueous compositions. The compositions used in the process herein have a pH of from 0 to 6, preferably from 1 to 5, and more preferably from 2 to 5 and most preferably from 3 to 5. Acidic compositions are preferred herein for stability reasons. The compositions used according to the present invention may comprise optional ingredients like bleach activators, surfactants, perfumes, brighteners, chelating agents, radical scavengers, stabilisers, soil suspenders, dye transfer agents, solvents, dyes, other amines, or mixtures thereof. Preferred optional ingredients are further described in more details hereinafter. The compositions The present invention also encompasses a liquid composition suitable for pretreating fabrics, comprising from 2% to 15% by weight of the total composition of a peroxygen bleach, a soil dispersing agent selected from the group consisting of an ethoxylated monoamine, an ethoxylated diamine, an ethoxylated polyamine, an ethoxylated amine polymer and mixture thereof, as defined hereinbefore, and a surfactant, said composition being formulated either as an emulsion or a microemulsion. It is by adding such a soil dispersing agent in a liquid composition comprising a peroxygen bleach, a surfactant and being formulated either as an emulsion or a microemulsion, that not only improved stain removal performance is obtained especially under pretreatment conditions, on various stains including greasy stains, enzymatic stains, clay/mud stains as well as improved bleaching performance but also desirable viscosity is achieved. It has now been found that the soil dispersing agents according to the present invention are easily processed in a composition being formulated either as an emulsion or a microemulsion, while providing the appropriate viscosity, i.e., the viscosity of said composition is reduced, whatever the viscosity was before the addition of said soil dispersing agents into said composition comprising a peroxygen bleach and a surfactant. Any surfactant or a mixture thereof known to those skilled in the art are suitable to be used in the compositions of the present invention being formulated either as an emulsion or a microemulsion including anionic, nonionic, cationic, amphotheric, zwitternionic surfactants at a level of from 0.01% to 50% by weight of the total composition, preferably from 1% to 30%, and more preferably from 2% to 20%. Preferably a surfactant system is used in the compositions according to the present invention comprising at least one hydrophilic surfactant and at least one hydrophobic surfactant. Said two surfactants in order to form emulsions or microemulsions which are stable preferably have different HLB values (hydrophilic lipophilic balance) and typically the difference in value of the HLBs of said two surfactants is at least 1, preferably at least 2 and most preferably at least 3. By "hydrophobic surfactant" it is meant herein a surfactant having an HLB up to 10 or mixtures thereof, preferably below 10, more preferably below 9. Indeed, the hydrophobic surfactants to be used herein have excellent grease cutting properties, i.e., they have a solvent effect which contributes to hydrophobic soil removal. By "hydrophilic surfactant" it is meant herein a surfactant having an HLB above 10 or mixtures thereof, preferably above 10.5, and more preferably above 11. Typically, the compositions according to the present invention formulated either as an emulsion or a microemulsion comprise from 1 % to 50 % by weight of the total composition of said hydrophilic and hydrophobic surfactants, more preferably from 5 % to 40 % and most preferably from 8 % to 30 %. The preferred compositions according to the present invention comprise at least from 0.01 % by weight of the total composition of said hydrophobic surfactant, or mixtures thereof, preferably at least 2 % and more preferably at least 4 % and at least from 0.01 % by weight of the total composition of said hydrophilic surfactant, or mixtures thereof, preferably at least 2%, and more preferably at least 4%. Accordingly, particularly preferred surfactants to be used in the compositions according to the present invention are nonionic surfactants. Indeed, suitable nonionic surfactants for use herein include alkoxylated fatty alcohols preferably, fatty alcohol ethoxylates and/or propoxylates. Indeed, a great variety of such alkoxylated fatty alcohols are commercially available which have very different HLB values (hydrophilic / lipophilic balance). The HLB values of such alkoxylated nonionic surfactants depend essentially on the chain length of the fatty alcohol, the nature of the alkoxylation and the degree of alkoxylation. Hydrophilic nonionic surfactants tend to have a high degree of alkoxylation and a short chain fatty alcohol, while hydrophobic surfactants tend to have a low degree of alkoxylation and a long chain fatty alcohol. Surfactant catalogs are available which list a number of surfactants including nonionics, together with their respective HLB values. Suitable chemical processes for preparing the nonionic surfactants for use herein include condensation of corresponding alcohols with alkylene oxide, in the desired proportions. Such processes are well-known to the man skilled in the art and have been extensively described in the art. As an alternative, a great variety of alkoxylated alcohols suitable for use herein is commercially available from various suppliers. Preferred hydrophobic nonionic surfactants to be used in the compositions according to the present invention are surfactants having an HLB up to 10 and being according to the formula RO-(C 2 H 4 O) n (C 3 H 6 O) m H, wherein R is a C 6 to C 22 alkyl chain or a C 6 to C 28 alkyl benzene chain, and wherein n+m is from 0.5 to 5 and n is from 0 to 5 and m is from 0 to 5 and preferably n+m is from 0.5 to 4.5 and, n and m are from 0 to 4.5. The preferred R chains for use herein are the C 8 to C 22 alkyl chains. Accordingly, suitable hydrophobic nonionic surfactants for use herein are Dobanol R 91-2.5 (HLB= 8.1; R is a mixture of C 9 and C 11 alkyl chains, n is 2.5 and m is 0), or Lutensol R TO3 (HLB=8; R is a mixture of C 13 and C 15 alkyl chains, n is 3 and m is 0), or Tergitol R 25L3 (HLB= 7.7; R is in the range of C 12 to C 15 alkyl chain length, n is 3 and m is 0), or Dobanol R 23-3 (HLB=8.1; R is a mixture of C 12 and C 13 alkyl chains, n is 3 and m is 0), or Dobanol R 23-2 (HLB= 6.2; R is a mixture of C 12 and C 13 alkyl chains, n is 2 and m is 0), or mixtures thereof.

In the embodiment of the present invention where the compositions are formulated as emulsions said compositions are opaques. In centrifugation examination, it was observed that said emulsions herein showed no phase separation after 15 minutes at 6000 rpm. Under microscopic examination, said emulsions appeared as a dispersion of droplets in a matrix. In the embodiment of the present invention where the compositions are formulated as microemulsions said compositions are macroscopically transparent in the absence of opacifiers and dyes. In centrifugation examination, it was observed that said microemulsions herein showed no phase separation after 15 minutes at 6000 rpm. Under microscopic examination, said microemulsions appeared as a dispersion of droplets in a matrix. We have observed that the particles had a size which is typically around or below 3 micron diameter, preferably below 2 micron diameter. In a preferred embodiment of the emulsions of the present invention wherein the emulsions further comprise a non-water soluble ingredient to emulsify like a bleach activator as described hereinafter, the emulsifying system meets the equation: HLB(X) = weight%A 100 x HLB(A) + weight%B 100 x HLB(B) and weight %A+ weight%B = 100%; where HLB (X) refers to the HLB of the ingredient to emulsify, if several ingredients are present to emulsify X refers to all of them (weighted average based on % of each ingredient in the formula), HLB (A) refers to the HLB of the hydrophilic surfactant, or mixtures thereof, and HLB (B) refers to the HLB of the hydrophobic surfactant, or mixtures thereof. In a particularly preferred embodiment of the emulsions of the present invention, wherein the emulsions may further comprise a bleach activator like acetyl triethyl citrate, an adequate surfactant system, would comprise a hydrophobic nonionic surfactant with for instance an HLB of 6, such as a Dobanol R 23-2 and a hydrophilic nonionic surfactant with for instance an HLB of 15, such as a Dobanol R 91-10. Other suitable nonionic surfactant systems comprise for example a Dobanol R 23-6.5 (HLB about 12) and a Dobanol R 23 (HLB below 6) or a Dobanol R 45-7 (HLB=11.6) and a Dobanol 23-3 (HLB=8.1). The bleaching compositions of the present invention formulated in the form of emulsions or microemulsions are chemically stable. By "chemically stable" it is meant herein that said compositions of the present invention comprising a peroxygen bleach do not undergo more than 10% available oxygen loss at 50°C in 2 weeks. The concentration of available oxygen can be measured by chemical titration methods known in the art, such as the iodimetric method, the permanganometric method and the cerimetric method. Said methods and the criteria for the choice of the appropriate method are described for example in "Hydrogen Peroxide", W. C. Schumb, C. N. Satterfield and R. L. Wentworth, Reinhold Publishing Corporation, New York, 1955 and "Organic Peroxides", Daniel Swem, Editor Wiley Int. Science, 1970. Alternatively, the stability of said compositions may also be evaluated by a bulging test method. Accordingly, said bleaching compositions of the present invention may be packaged in a given deformable container/bottle without compromising the stability of said container/bottle comprising it upon standing, for long periods of time. The liquid compositions of the present invention formulated either as an emulsion or microemulsion are typically aqueous and are formulated in the acidic pH range up to 6, preferably at a pH of from 1 to 5, more preferably of from 2 to 5 and most preferably from 3 to 5. Formulating the compositions of the present invention in the acidic pH range contributes to the stability of said compositions. The pH of the compositions of the present invention can be adjusted by using organic or inorganic acids. Optionals The compositions of the present invention may further comprise optional ingredients like bleach activators, stabilisers, chelating agents, radical scavengers, builders, soil suspenders, dye transfer agents, solvents, brighteners, perfumes, foam suppressors or dyes or mixtures thereof. As an optional but highly preferred ingredient, the compositions of the present invention comprise a bleach activator or mixtures thereof. By "bleach activator", it is meant herein a compound which reacts with hydrogen peroxide to form a peracid. The peracid thus formed constitutes the activated bleach. Paticularly suitable bleach activators to be used herein are hydrophobic bleach activators, i.e., a bleach activator which is not substantially and stably miscible with water. Typically, such hydrophobic bleach activators have a secondary HLB (hydrophilic lipophilic balance) below 11, preferably below 10. Secondary HLB is known to those skilled in the art and is defined for example in "Emulsions theory and practice" by P. Becher, Reinhold, New York, 1957, or in "Emulsion science" by P. Sherman, Academic Press, London, 1969. Suitable bleach activators to be used herein include those belonging to the class of esters, amides, imides, or anhydrides. Examples of suitable compounds of this type are disclosed in British Patent GB 1 586 769 and GB 2 143 231 and a method for their formation into a prilled form is described in European Published Patent Application EP-A-62 523. Suitable examples of such compounds to be used herein are tetracetyl ethylene diamine (TAED), sodium 3,5,5 trimethyl hexanoyloxybenzene sulphonate, diperoxy dodecanoic acid as described for instance in US 4 818 425 and nonylamide of peroxyadipic acid as described for instance in US 4 259 201 and n-nonanoyloxybenzenesulphonate (NOBS).

A particular family of bleach activators of interest was disclosed in EP 624 154, and particularly preferred in that family is acetyl triethyl citrate (ATC). Acetyl triethyl citrate has the advantage that it is environmental-friendly as it eventually degrades into citric acid and alcohol. Furthermore, acetyl triethyl citrate has a good hydrolytical stability in the product upon storage and it is an efficient bleach activator. Finally, it provides good building capacity to the composition. The compositions according to the present invention may comprise from 0.01% to 20% by weight of the total composition of said bleach activator, or mixtures thereof, preferably from 1% to 10%, and more preferably from 3% to 7%. Suitable chelating agents to be used herein include chelating agents selected from the group of phosphonate chelating agents, amino carboxylate chelating agents, polyfunctionally-substituted aromatic chelating agents, and further chelating agents like glycine, salicylic acid, aspartic acid, glutamic acid, malonic acid, or mixtures thereof.

Such phosphonate chelating agents are commercially available from Monsanto under the trade name DEQUEST® . The most preferred phosphonate chelating agent to be used herein is aminotri(methylene phosphonic acid), herein referred to as ATMP. Indeed, it has been found that the addition of ATMP, i.e. the compound of formula : in a liquid composition of the present invention considerably reduces the damage otherwise associated with the pretreatment of fabrics with peroxygen bleach-containing compositions, especially those fabrics which contain metal ions, such as copper, iron, chromium, and manganese. Polyfunctionally-substituted aromatic chelating agents may also be useful in the compositions herein. See U.S. patent 3,812,044, issued May 21, 1974, to Connor et al. Preferred compounds of this type in acid form are dihydroxydisulfobenzenes such as 1,2-dihydroxy -3,5-disulfobenzene.

The presence of chelating agents, especially ATMP, and/or radical scavengers allows to contribute to the safety profile of the compositions of the present invention suitable for pretreating a soiled colored fabric upon prolonged contact times before washing said fabric. The compositions of the present invention may further comprise up to 20%, preferably from 2% to 10% by weight of the total composition of a solvent or mixtures thereof. More particularly, it has been found that the addition of a solvent system comprising at least one hydrophobic solvent and at least one hydrophilic solvent, in a liquid composition according to the present invention, further contributes to the benefits of said composition, i.e., further improves the overall stain removal performance on various type of stains including greasy stains, enzymatic stains as well as bleachable stains.

Any polymeric soil release agent known to those skilled in the art can optionally be employed in the compositions and processes of this 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 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 procedures. The polymeric soil release agents useful herein especially include those soil release agents having: (a) one or more nonionic hydrophile components consisting essentially of (i) polyoxyethylene segments with a degree of polymerization of at least 2, or (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 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 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 surface, said hydrophile segments preferably comprising at least about 25% oxyethylene units and more preferably, especially for such components having about 20 to 30 oxypropylene units, at least about 50% oxyethylene units; or (b) one or more hydrophobe components comprising (i) C 3 oxyalkylene terephthalate segments, wherein, if said hydrophobe components also comprise oxyethylene terephthalate, the ratio of oxyethylene terephthalate:C 3 oxyalkylene terephthalate units is about 2:1 or lower, (ii) C 4 -C 6 alkylene or oxy C 4 -C 6 alkylene segments, or mixtures therein, (iii) poly (vinyl ester) segments, preferably polyvinyl acetate), having a degree of polymerization of at least 2, or (iv) C 1 -C 4 alkyl ether or C 4 hydroxyalkyl ether substituents, or mixtures therein, wherein said substituents are present in the form of C 1 -C 4 alkyl ether or C 4 hydroxyalkyl ether cellulose derivatives, or mixtures therein, and such cellulose derivatives are amphiphilic, whereby they have a sufficient level of C 1 -C 4 alkyl ether and/or C 4 hydroxyalkyl ether units to deposit upon conventional polyester synthetic fiber surfaces and retain a sufficient level of hydroxyls, once adhered to such conventional synthetic fiber surface, to increase fiber surface hydrophilicity, or a combination of (a) and (b). Typically, the polyoxyethylene segments of (a)(i) will have a degree of polymerization of from about 1 to about 200, although higher levels can be used, preferably from 3 to about 150, more preferably from 6 to about 100.
