Abstract
A 2-in-1 conditioning shampoo includes an anionic surfactant and a cationic hair conditioning agent. The cationic hair conditioning agent is a fatty aliphatic quaternary ammonium compound having ester linkages. The cationic hair conditioning agent can be prepared by reacting an alkanol amine with a fatty acid or fatty acid ester having an aliphatic group of from about 11 to about 24 carbon atoms and thereafter quaternizing the resulting esteramine with an alkylating agent.
