Abstract
The liquid composition is a dual cleanser and mosturizer that is stable and on a macro scale is homogeneous. The dual cleansing and lipid moisturizing liquid composition of this invention comprises: by weight parts of the liquid composition: PA1 (a) from about 5 parts to about 30 parts of lipid skin moisturizing agent having a Vaughan Solubility Parameter (VSP) of between 5 and 10; PA1 (b) from about 0.3 parts to 5 parts of a water dispersible gel forming polymer wherein said polymer is an anionic, nonionic, cationic or hydrophobically modified polymers, selected from the group consisting of cationic polysaccharides of the cationic guar gum class with molecular weights of 1,000 to 3,000,000, anionic, cationic and nonionic homopolymers derived from acrylic and/or methacrylic acid, anionic, cationic and nonionic cellulose resins; cationic copolymers of dimethyldialkylammonium chloride and acrylic acid; cationic homopolymers of dimethyldialkylammonium chloride; cationic polyalkylene and ethoxypolyalkylene imines polyethylene glycol of molecular weight from 100,00 to 4,000,000; and mixes thereof; and, PA1 (c) from about 5 part to about 30 parts of a synthetic surfactant; PA1 (d) from a…
