Abstract
An aqueous composition comprising PA1 a. a skin cleansing effective amount of a surfactant or mixture thereof; PA1 b. a silicone in quantities of from about 0.1 to about 8 wt. % of the composition; PA1 c. a hydrocarbonaceous material in quantities of from about 0.1 to about 8 wt. % of the composition; PA1 d. a cationic polymer in quantities of from about 0.02 to about 1 wt. % of the composition; PA1 e. a combination of a polyacrylate thickening polymer and an acrylate methacrylate copolymer wherein the ester group of the methacrylate is alkyl of about 12 to about 20 carbon atoms, said alkyl having about fourteen to about twenty six ethoxy groups and the acrylate is one or more monomers of acrylic acid, methacrylic acid or one of their simple esters in quantities sufficient to provide both viscosity and visual phase stabilization; and PA1 f. the balance water.
