Zusammenfassung: | A method of permanently waving keratin substrates, such as hair, by applying thereto keratin softening agents and a quaternary ammonium halide salt keratin alkylating agent. Quaternary ammonium halide salts that make suitable keratin alkylating agents are mono, bis and tri quaternary reaction products or mixtures thereof selected from the group consisting of the reaction products of (1) hexamethylaminetetramine and cyanuric chloride; (2) hexamethylaminetetramine and 1,4-dichlorobutene; (3) hexamethylaminetetramine and p-bis-chloromethylbenzene; and (4) triethanolamine and cyanuric chloride. |
