Patent ID: 8623802

Claim:
An aqueous composition comprising: (a) an acyl isethionate of formula (I): R 1 CO 2 CH 2 CH 2 SO 3 − M + (I) wherein R 1 is an alkyl or alkenyl group having from 7 to 21 carbon atoms and M + is a cation; and (b) a further surfactant selected from nonionic surfactants, cationic surfactants and anionic surfactants other than those of formula (I); wherein when component (b) is a nonionic surfactant it is selected from reaction products of aliphatic alcohols, acids amides or alkyl phenols with alkylene oxides; wherein when component (b) is a cationic surfactant it is selected from quaternary ammonium compounds, polymeric cationic surfactants and dialkylaminoalkyl alkyl amides and salts thereof; wherein when component (b) is an anionic surfactant it is selected from salts of C 12 to C 18 carboxylic acids, ethoxylated carboxylic acids, ester carboxylates and ethoxylated ester carboxylates and sarcosinates, alcohol sulfates, alcohol ether sulfates, alkyl sulfonates, alpha-olefin sulfonates, alkyl ether sulfates, alkyl sulfates, alkenyl sulfates, alkyl glyceryl ether sulfates, sulfosuccinates, sulfosuccinamates, sarcosinates, sulphoacetates, phosphate esters, acyl lactates, alkyl ether carboxylates, glyceryl ether carboxylates and isethionate compounds not of formula (I); alkyl aryl sulfonates; primary alkane disulfonates; alkene sulfonates; sulfonates of alkylphenolpolyglycol ethers; salts of alkyl sulfopolycarboxylic acid esters; alkyl sulfosuccinates and salts thereof, alkyl ether sulfosuccinates and salts thereof, sulfated derivatives of fatty acids and polyglycols; alkyl and acyl sarcosinates; sulfoacetates; alkyl phosphates; acyl lactates; salts of lipoamino acids; wherein component (a) comprises at least 11 wt % and up to 40 wt % of the composition; wherein component (b) comprises up to 30 wt % of the composition; wherein component (a) and component (b) together comprise more than 18 wt % and up to 60 wt % of the composition; wherein the composition is substantially free of taurate surfactants or comprises less than 2 wt % of taurate surfactants; wherein the composition is substantially free of alkanolamides or comprises less than 0.1 wt % of alkanolamides; wherein the composition is substantially free of alkylamine oxides or comprises less than 0.1 wt % of alkylamine oxides; and wherein the composition is a flowable composition at one or more temperatures between 15° C. and 45° C.
