Abstract

An aqueous hair-treatment preparation containing an antistatic additive imparting an antistatic effect to the hair, characterized in that said antistatic additive is at least one cationic polymer produced by the process of (1) epoxidizing 1,3-diene homopolymers or copolymers (2) reacting the epoxide compound so produced with low molecular weight amines selected from the group consisting of primary amines, secondary amines and tertiary amines, and (3) converting the reaction products into the salt form or into polymeric quaternary ammonium salts. The use of these polymeric amine salts or quaternary ammonium salts in cosmetic hair-treatment preparations provides these preparations with antistatic effects. Preferred cationic polymers are obtained by the epoxidation of polybutadiene, of which more than 50% of the monomer units show the 1,4-cis-configuration, reaction with dimethylamine or morpholine and conversion into the hydrochlorides or alkylation with glycidyl trimethylammonium chloride, 3-chloro-2-hydroxypropyl trimethylammonium chloride or ethylene oxide. The cationic polymers are preferably used in shampoos in quantities of from 0.5 to 5.0% by weight in addition to 5 to 30% by …
