Abstract
Abstract Hair treatment agent and process for hair treatment on the basis of an alcoholic solution containing a synergistic combination of (A) 0.1 to 40% by weight cetyl alcohol lactic ester and (B) 0.5 to 30% by weight of a monomer quaternary ammonium compound as well as 0 to 15% by weight water. The hair treatment agent may be diluted with water before use. It is applied to the still wet hair after the hair wash and is rinsed off with water after a reaction time of from 3 to 5 minutes. An excellent improvement of the combabillity, the touch and the luster of the hair is noticed with respect to hair treatments with the sole content of one of the two components (A) or (B).
