Claims17
A method for personal cleansing comprising applying to the skin or hair an aerated rinse-off cleansing composition substantially-free of a surfactant comprising:
- (a) from about 0.01% to about 20% by weight of a viscosity enhancing water-soluble cationic polymer having a molecular weight of from about 1,000 to about 3,000,000 wherein said viscosity enhancing polymer accounts for a rise in the viscosity of the composition, without the polymer, of at least about 1 centipoise, and
- (b) from about 20% by weight to about 99.8% by weight of water.
