Finally, it provides good building capacity to the composition.
- compositions according to the present invention comprise from 0.1 % to 20% by weight of the total composition of said liquid hydrophobic bleach activator, or mixtures thereof, preferably from 1 % to 10%, and more preferably from 1 .5% to 7%.

- bleachable stains examples include tea, coffee, wine and the like.
- enzymatic stains examples include blood.
- the stain removal performance of a 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 a fabric, preferably to the stained portion of said fabric, left to act from about 1 to about 10 minutes, preferably 5 minutes, and said pretreated fabric is then washed according to common washing conditions, at a temperature of from 30°C to 70°C for a period of time sufficient to bleach said fabric.
- the stain removal performance is then 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 compositions but without any long chain (C1 2-C1 6) acyl sarcosinates.
- a visual grading scale may be used to assign differences in panel score units (psu), in a range from 0 to 4.
- the present invention encompasses the use of a long chain (C 1 2-C1 6) acyl sarcosinate, in a liquid composition having a pH up to 7, preferably in a peroxygen bleach-containing liquid composition, for improving the stain removal performance of said composition under pretreatment conditions, i.e., when pretreating a soiled fabric with said composition before said fabric is washed.
- a long chain (C 1 2-C1 6) acyl sarcosinate in a liquid composition having a pH up to 7, preferably in a peroxygen bleach-containing liquid composition, for improving the stain removal performance of said composition under pretreatment conditions, i.e., when pretreating a soiled fabric with said composition before said fabric is washed.
- the peroxygen bleach-containing compositions according to the present invention comprise a liquid hydrophobic bleach activator and are thus formulated either as aqueous emulsions of said liquid hydrophobic bleach activator in a matrix comprising water, the peroxygen bleach and an emulsifying surfactant system comprising said long chain acyl sarcosinate (as a hydrophilic surfactant having an HLB above 1 0), or as microemulsions of said liquid hydrophobic bleach activator in a matrix comprising water, the peroxygen bleach and a hydrophilic surfactant system comprising at least said long chain acyl sarcosinate.
- said long chain acyl sarcosinate may be used, as sole emulsifying surfactant, to emulsify said hydrophobic bleach activator. Accordingly, if said long chain acyl sarcosinate is present in said emulsions as the sole emulsifying surfactant, it is preferably present at a level of from 1 % to 6% by weight of the total composition.
- Preferred peroxygen bleach-containing emulsions herein comprise an emulsifying surfactant system of at least two different surfactants, i.e. at least a hydrophobic surfactant having an HLB up to 9.5 or mixtures thereof, and at least a hydrophilic surfactant having an HLB above 1 0 or mixtures thereof, in order to emulsify the liquid hydrophobic bleach activator.
- said two different surfactants in order to form emulsions which are stable must have different HLB values (hydrophilic / lipophilic balance), and preferably the difference in value of the HLBs of said two surfactants is at least 1 , preferably at least 2.
- the preferred emulsions according to the present invention 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 emulsions according to the present invention comprise at least from 0.01 % by weight of the total emulsion 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 emulsion of said hydrophilic surfactant, or mixtures thereof, preferably at least 2%, and more preferably at least 4%.
- hydrophilic surfactants having an HLB above 10 to be used in said emulsions herein are said long chain acyl sarcosinates alone or in mixture with other hydrophilic surfactants having an HLB above 1 0, preferably hydrophilic nonionic surfactants having an HLB above 1 0 and more preferably above 1 0.5.
- Preferred to be used herein as the hydrophobic surfactants are the hydrophobic nonionic surfactants.
- Said hydrophobic nonionic surfactants to be used herein have an HLB up to 9.5, preferably below 9.5, more preferably below 9. Indeed, the hydrophobic nonionic surfactants to be used herein have excellent grease cutting properties, i.e. they have a solvent effect which contributes to hydrophobic soils removal.
- the hydrophobic surfactants act as carrier of the hydrophobic brighteners onto the fabrics allowing thereby said brighteners to work in close proximity with the fabrics surface since the beginning of the wash.
- 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.
- Surfactants 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.
