ABSTRACT:
Hair is conditioned by applying to it a hair conditioning amide (a mononeoalkanoamide) of trialkylacetic acid (neoalkanoic acid), such as a monoamide of a mono-N-higher alk(en)yl amine and a trialkylacetic acid of 5 to 16 carbon atoms, or a polyamide of a trialkylacetic acid and a polyamine wherein the trialkylacetic acid moieties are of 1 to 10 carbon atoms in each of the alkyls thereof and each of the polyamine moieties contains from 2 to 5 amino groups. The hair conditioning trialkylacetamide is preferably applied to previously wet hair in aqueous solution, emulsion, dispersion or suspension, which is combed into the hair, after which the hair is rinsed with water, leaving on it a conditioning amount of the trialkylacetamide, which improves the condition of the hair by decreasing flyaway, increasing ease of wet combing, increasing ease of dry combing and/or increasing hair luster (especially compared to such luster when quaternary ammonium halide conditioning agents are used repeatedly). Although the conditioning agents of this invention are effective for the treatment of hair, deposit on the hair from aqueous media and are effective to condition the hair, they are removable from it by conventional shampooing, and therefore do not accumulate on the hair, as do quaternary ammonium salt conditioning agents, which accumulation is considered to be objectionable. Also, the present trialkylacetamides do not react with anionic detergent (as do quaternary ammonium halide conditioners), and therefore do not produce objectionable fatty deposits on the hair.
