Abstract
Abstract Cleansing compositions for the hair and skin which deposit an emollient, conditioning film thereon during washing are disclosed. The compositions, which may be in a liquid or semisolid form, are oil-in-water emulsions characterized by a particular particle size distribution of the oil phase and are comprised of from about 10 to about 70 percent by weight petrolatum, from about 5 to about 30 percent by weight of one or more organic foaming detergents, from about 1 to about 10 percent by weight of an emulsifier, from about 0.5 to about 5 percent weight of an organic foam stabilizer, from about 0 to about 20 percent by weight of one or more emollient substances other than petrolatum, and water.
