Abstract

A composition for treating keratin substances comprising selected amphoteric polysaccharide derivatives, preferably guar gum which contain a cationic group comprising an amino, ammonium, imino, sulfonium or phosphonium group and an anionic group comprising a carboxyl, sulfonate, sulfate, phosphate or phosphonate group.

Claims

1. A keratin treating cosmetic composition comprising a cosmetic vehicle and from about 0.1 to 20% by weight a guar gum having a cationic group selected from the group consisting of tertiary amino and quarternary ammonium groups and is present in an amount represented by a DS of from about 0.1 to 0.6 and anionic group selected from the group consisting of carboxyl, sulfonate, sulfate, phosphate and phosphonate groups and is present in an amount represented by a DS of from about 0.1 to 0.6 wherein the cosmetic vehicle is an aqueous system and the guar gum has a net positive charge.
