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.
Claims21
A mild soap bar composition comprising:
- (1) 50-90% soap;
- (2) an effective amount of a hydrated cationic polymeric skin conditioner uniformly distributed and incorporated in said soap bar, said cationic polymeric skin conditioner having a molecular weight of from 1000 to 3,000,000, said cationic polymeric skin conditioner comprising:
- from about 0.2% to about 5% of a hydrated cationic guar gum having a molecular weight of at least about 200,000;
- and from 0% to 5% of another cationic polymeric skin conditioner selected from the group consisting of:
- (I) other cationic polysaccharides;
- (II) cationic copolymers comprising monomers selected from saccharides and synthetic cationic monomers, and mixtures thereof;
- (III) synthetic polymers selected from the group consisting of:
- (A) cationic polyakylene imines,
- (B) cationic ethoxypolyalkylene imines, and
- (C) cationic poly(N-(3-(dimethylammonio)propyl)N'-(3-(ethyleneoxyethylene dimethylammonio)propyl)urea dichloride);
- and
- (IV) mixtures thereof;
- wherein said bar is substantially free of unhydrated polymeric particles greater than 30 microns;
- and
- (3) said soap bar having about 7-15% moisture.
A mild soap composition comprising:
- (1) about 50-90% of a mixture of soap and synthetic surfactants wherein said soap is said bars' primary surfactant;
- (2) an effective amount of a hydrated cationic polymeric skin conditioner uniformly distributed and incorporated in said soap bar, said cationic polymeric skin conditioner having a molecular weight of from 1000 to 3,000,000, said cationic polymeric skin conditioner comprising:
- from about 0.2% to about 5% of a hydrated cationic guar gum having a molecular weight of at least 200,000 and from 0% to 5% of another cationic polymeric skin conditioner selected from the group consisting of:
- (I) other cationic polysaccharides;
- (II) cationic copolymers having monomers selected from saccharides and synthetic monomers, and
- (III) synthetic polymers selected from the group consisting of:
- (A) cationic polyakylene imines,
- (B) cationic ethoxypolyalkylene imines, and
- (C) cationic poly(N-(3-(dimethylammonio)propyl(N'-(3-ethyleneoxyethylene dimethylammonio)propyl)urea dichloride);
- and
- (IV) mixtures thereof;
- wherein said bar is substantially free of unhydrated polymeric particles greater than 30 microns;
- and
- (3) 7-15% moisture.
