  • Mild skin cleansing soap bar with hydrated cationic polymer skin conditioner
    Patent number: 5064555
    Abstract: Disclosed is a mild skin cleansing soap bar composition comprising: (1) 50-90% soap, and (2) a hydrated cationic polymeric skin conditioner. The physical composition of the bar is such that the hydrated polymer is substantially uniformly distributed and well incorporated in the soap. The hydrated cationic polymer improves the mildness of the soap bar to a level approaching that of bars made with very mild synthetic surfactants, while maintaining the desirable physical characteristics of a pure soap bar without the polymer.The preferred polymer is a hydrated cationic guar gum having a typical aqueous viscosity at 1% of from about 125 cps to about 3500.+-.500 cps.
