Abstract:
A hair treatment composition comprising, as a hair setting ingredient, an effective amount of at least one crosslinked, water-soluble or water-dispersible polyurethane or a salt thereof, which polyurethane is formed by reactingA) at least one polyurethane prepolymer having terminal isocyanate groups formed from a) at least one compound having a molecular weight in the range from 56 to 300 which comprises two active hydrogen atoms per molecule, b) at least one polymer having two active hydrogen atoms per molecule, c) optionally a polysiloxane, d) optionally at least one compound which has two active hydrogen atoms and at least one ionogenic or ionic group per molecule, e) at least one diisocyanate, and B) at least one polymer having isocyanate-reactive groups selected from hydroxyl, primary and secondary amino and/or carboxyl groups, where the polymer B) is selected from B1) polymers comprising in copolymerized form at least one &agr;,&bgr;-ethylenically unsaturated monomer which additionally comprises at least one isocyanate-reactive group per molecule, B2) polyesters, B3) silicon-poly(alkylene oxide) copolymers, and mixtures thereof, wherein at least one of components A) and/or B) is soluble or dispersible in water and at least one of components A) and/or B) comprises at least one siloxane group, and which composition is in form of an aqueous dispersion, an alcoholic solution or an aqueous-alcoholic solution.
