Patent ID: 8268767

Claim:
A liquid cleansing composition comprising: (1) 1 to 30% by wt. of a surfactant system comprising: (a) 30 to 70% by wt of surfactant system of a mixture of alkanoyl glycinate and alkanoyl sarcosinate wherein the ratio of said alkanoyl glycinate to alkanoyl sarcosinate is of from 1/0 to 1/3 and the alkyl group on the alkanoyl chain is C8 to C20; (b) 10 to 60% by weight of surfactant system of a fatty acyl isethionate product which product comprises 40 to 80% fatty acyl isethionate and 15 to 50% free fatty acid and/or fatty acid salt, and (c) 20 to 80% by weight of surfactant system of amphoteric and/or zwitterionic surfactant; wherein greater than 25% and less than 45% of the fatty acyl isethionate is of chain length C16 or greater; and greater than 50% of chain length of free fatty acid and fatty acid salt groups combined are of chain length C 16 to C 20 wherein the composition comprises 3% or less of an alkyl sulfate anionic surfactant; and wherein total irritation score using Patch Test Methodology is less than 75% relative to a 0.5% solution of sodium dodecyl sulfate used as control in the same Patch Test; and (2) 1 to 60% by wt. skin or hair benefit agent.
