Abstract:
A lathering skin cleansing liquid composition comprising by weight parts of the liquid composition:(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;(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 or nonionic homopolymers derived from acrylic or methylacrylic acid; anionic, cationic or nonionic cellulose resins; cationic copolymers of dimethyldialkylammonium chloride or acrylic acid; cationic homopolymers of dimethyldialkylammonium chloride; cationic polyalkylene or ethoxypolyalkylene imines; polyethylene glycol of molecular weight from 100,00 to 4,000,000; and mixtures thereof;(c) from about 5 part to about 30 parts of a synthetic surfactant;(d) from about 0 part to about 15 part of a C8 to C14 fatty acid soap; wherein said soap has a counterion selected from the group consisting of K, NH4, N(CH2CH2OH)3, and mixtures thereof; and(e) from about 0.5 parts to about 6 parts of an additional non-polymeric thickener selected from the group consisting of C10-C8 fatty alcohol and mixtures thereof;(f) water;wherein said lathering skin cleansing composition is a liquid,wherein said lathering skin cleansing liquid composition has a Lipid Deposition Value (LDV) of at least 5 up to about 1000;wherein said synthetic surfactant and said soap has a combined CMC equilibrium surface tension value of from 15 to 50; andwherein said composition is free of C10-C20 ethylene glycol fatty acid esters.
