Abstract
The disclosure relates to compositions comprising (a) at least one amphoteric surfactant, (b) at least one glycolipid, (c) at least one cationic polymer from about 0.05% to about 2%; and (d) at least one cosmetically acceptable solvent wherein the cleansing system is essentially free of phenoxyethanol, and wherein the pH of the composition is between 4 and 8, and wherein the ratio of a to b is from about 0.4 to about 4, and wherein the total concentration of a and b combined is about 10 to about 20% of the total weight of the composition. The compositions can be used as rinse-off compositions for cleansing skin.

- (b) at least one glycolipid;
- (c) at least one cationic polymer from about 0.05% to about 0.2%, by weight, and chosen from chitosan, polylysine, or a mixture thereof, and
- (d) at least one cosmetically acceptable solvent;
- wherein the cleansing system is essentially free of phenoxyethanol,
- wherein the pH of the composition is between 4 and 8,
- wherein the weight ratio of the at least one amphoteric surfactant to the at least one glycolipid is from about 0.4 to about 4, and
- wherein the total concentration of the at least one amphoteric surfactant and the at least one glycolipid combined is about 9 to about 20% of the total weight of the composition.
A coacervate cleansing system comprising a composition comprising:
- (a) at least one amphoteric surfactant selected from the group consisting of cocamidopropyl hydroxysultaine and coco betaine from about 3% to about 8% by weight, relative to the total weight of the composition;
- (b) at least one glycolipid selected from the group consisting of rhamnolipid and sophorolipid from about 2% to about 7% by weight, relative to the total weight of the composition;
- (c) at least one cationic polymer selected from the group consisting of chitosan and polylysine from about 0.1% to about 0.2%;
- and

- iii) the cleansing system is essentially free of phenoxyethanol;
- iv) the pH of the composition is between 4 and 8;
- v) the weight ratio of the at least one amphoteric surfactant to the at least one glycolipid is from about 0.4 to about 4;
- and
- vi) the total concentration of the at least one amphoteric surfactant and the at least one glycolipid combined is about 9% to about 20% of the total weight of the composition.
A method for cleansing skin comprising applying to the skin of a subject a coacervate cleansing system comprising a composition comprising:
- (a) at least one amphoteric surfactant selected from the group consisting of cocamidopropyl hydroxysultaine and coco betaine from about 3% to about 8% by weight, relative to the total weight of the composition;
- (b) at least one glycolipid selected from the group consisting of rhamnolipid and sophorolipid from about 2% to about 7% by weight, relative to the total weight of the composition;
- (c) at least one cationic polymer selected from the group consisting of chitosan and polylysine from about 0.1% to about 0.2%;
- and
- (d) at least one cosmetically acceptable solvent, including water;
- wherein:
- i) the composition is an aqueous composition;
- ii) the composition is free of polyquaternium cationic polymers;
- iii) the cleansing system is essentially free of phenoxyethanol;
- iv) the pH of the composition is between 4 and 8;
- v) the weight ratio of the at least one amphoteric surfactant to the at least one glycolipid is from about 0.4 to about 4;
- and
- vi) the total concentration of the at least one amphoteric surfactant and the at least one glycolipid combined is about 9% to about 20% of the total weight of the composition.
