Abstract
Disclosed is an aqueous cleansing composition comprising (a) at least one anionic surfactant that is not an alkyl sulfate or alkyl ether sulfate, (b) at least one amphoteric surfactant, (c) at least one thickener selected from a hydrophobically-modified acrylic acid based copolymer having a molecular weight from about 80,000 to about 2,500,000 grams per mole, (d) at least one cationic conditioning agent, and (e) optionally at least one nonionic surfactant; wherein the ratio of the anionic surfactant (a) to amphoteric surfactant (b) is less than about 9.5, by weight. Also disclosed are methods of cleaning and conditioning hair using said compositions and methods of making said compositions.

- (b) from about 0.5% to about 8%, by weight, of at least one amphoteric surfactant;
- (c) from about 0.01% to about 2.0%, by weight, of at least one thickener selected from a hydrophobically-modified acrylic acid based copolymer having a molecular weight from about 80,000 to about 2,500,000 grams per mole;
- (d) from about 0.01% to about 2%, by weight, of at least one cationic conditioning agent;
- and
- (e) optionally at least one nonionic surfactant;
- wherein the ratio of the anionic surfactant (a) to amphoteric surfactant (b) is less than about 9.5, by weight, all weights and ratios being based on the weight percent of each component in the final composition.
