Abstract
Abstract Agents containing fatty acid lactylates and glycolates of the formula WHEREIN RCO is the acyl radical of a fatty acid of from six to 22 carbon atoms, A is either CH3 or H and x is a number from about one to four and their ammonium, alkali metal and physiologically acceptable amine salts are used for conditioning hair, that is, for improving the texture and manageability as well as curl or wave retention of the hair.
