Patent ID: 8778910

Claim:
An aqueous, lamellar structured, skin cleaning composition comprising: a) about 15 to 40% by wt. of synthetic anion surfactant(s); b) about 5 to 30% by wt. of co-surfactant(s) selected from the group of amphoteric or nonionic surfactants or blends thereof; c) about 5 to 15% by wt. of C 12 to C 18 linear alkyl fatty acid(s); d) wherein the synthetic anionic surfactant(s): co-surfactant(s) ratio is about 0.5 to 3; e) wherein the synthetic anionic surfactant(s) and co- surfactant(s) to C 12 to C 18 linear alkyl fatty acid(s) ratio is about 2 to 6; and f) an effective amount of freeze-thaw stabilizer(s) selected from isooctanol, isotridecanol, isodecanol, polyoxyethylene(2)isooctylphenyl ether and blends thereof for maintaining at least 55% of the viscosity of the composition after one freeze-thaw cycle using the standard freeze-thaw test.
