Abstract
Toilet compositions in beta-phase bar form comprising 45% to 95% C.sub.8-24 fatty acid soap, 0% to 45% synthetic surfactant, and 0.01% to 5% of a water-soluble polymer. The compositions have improved lathering characteristics with excellent transparency/translucency.
Claims10
A beta-phase milled transparent or translucent toilet bar composition comprising:
- (a) from about 45% to about 95% by weight of soluble alkali metal soap of C.sub.8 -C.sub.24 fatty acids,
- (b) from about 0% to about 45% of synthetic surfactant selected from the group consisting of anionic surfactant, amphoteric surfactant, and mixtures thereof, and
- (c) from about 0.01% to about 5% of water-soluble polymer having a molecular weight of from about 20,000 to about 5,000,000 selected from the group consisting of
- (1) cationic polymer selected from the group consisting of cationic guar gums, quaternized cellulose ethers, quaternized vinylpyrrolidone acrylate or methacrylate copolymers of aminoalcohol, copolymers of dimethyldiallyl ammonium chloride and acrylamide, homopolymers of dimethyldiallyl ammonium chloride, and mixtures thereof;
- (2) nonionic polymers selected from the group consisting of guar gum and hydroxypropyl guar gum having a degree of substitution of from about 0.3 to about 1.2;
- and
- (3) mixtures thereof;
- wherin at least about 50% by weight of the soap is in the beta-phase.
