An aqueous cleansing composition, which comprises: (a) a short-chain anionic surfactant chosen from C6-C9 alkyl ether sulphates, C8-C11 acyl lactylates, C6-C9 acyl methyl taurates, C6-C9 acyl isethionates, C6-C11 fatty acid soaps, C6-C9 alkyl sulphates, C6-C11 acyl sarcosinates, C6-C9 alkyl sulphosuccinates, C6-C9 alkyl ether sulphosuccinates, or mixtures thereof; (b) a long-chain anionic surfactant chosen from C13-C18 alkyl ether sulphates, C13-C18 acyl lactylates, C13-C16 acyl methyl taurates, C13-C15 acyl isethionates, C13-C16 alkyl sulphates, C13-C16 acyl sarcosinates, C13-C16 alkyl sulphosuccinates, C13-C16 alkyl ether sulphosuccinates, or mixtures thereof; (c) optionally, a medium-chain anionic surfactant chosen from C10-C12 alkyl ether sulfates, C12 acyl lactylates, C10-C12 acyl methyl taurates, C10-C12 acyl isethionates, C10-C12 alkyl sulphates, C12 acyl sarcosinates, C10-C12 alkyl sulphosuccinates, C10-C12 alkyl ether sulphosuccinates, or mixtures thereof, and (d) water; wherein (i) at least one of the surfactants (a) and (b) is selected from the group consisting of the acyl lactylates, the acyl sarcosinates, the acyl methyl taurates, the alkyl ether sulphates and the acyl isethionates, or the short-chain anionic surfactant (a) is a C6-C11 fatty acid soap; (ii) if surfactant (c) is present, then the surfactants (a), (b) and (c) are present in an amount such that the weight ratio of (c): [(a) + (b)] is less than 1:1. |
