Abstract

A hair treatment agent is provided herein. The hair treatment agent includes in a cosmetic carrier (a) at least one compound of the general formula (I). R 1 denotes a hydrogen atom or a structural element of formula (II). x denotes an integer from 1 to 100. The radical R 2 in each of the structural elements of formula (II) can be selected independently of the preceding structural element of formula (II). M1 denotes the grouping —OM2 or a structural element of formula (III). y denotes an integer from 1 to 100. M2 denotes a hydrogen atom, an equivalent of one or more cations or an ammonia ion (NH 4 ) + .
