Abstract
A concentrate composition comprising: (a) at least 10 wt % of a glycol ester of a fatty acid; (b) at least one acyl alkyl isethionate surfactant of formula (I): wherein R1 represents an optionally substituted C4-C36 hydrocarbyl group; each of R2, R3, R4 and R5 independently represents hydrogen or a C1-C4 alkyl group and wherein at least one of R2, R3, R4 and R5 is not hydrogen; and M+ represents a cation; and (c) at least one zwitterionic or amphoteric surfactant.
