The invention relates to a novel cosmetic composition, containing, in a cosmetically acceptable medium, at least one hair conditioning agent and at least one aqueous dispersion of pre-cross-linked organopolysiloxanes composed of units of general formula (I), wherein R means a monovalent, saturated or unsaturated hydrocarbon group having 1 to 200 carbon atoms per group, which hydrocarbon group can contain one or more heteroatoms from the group N, P, S, O, and halogen, Rmeans a hydrogen atom or an alkyl group having 1 to 8 carbon atoms per group, Rmeans a monovalent, optionally substituted hydrocarbon group having 1 to 18 carbon atoms per group, AKT is a group of the formula &#x2014;CHNHR, &#x2014;CH2NR, or formula (II), wherein Rmeans a monovalent hydrocarbon group having 1 to 18 carbon atoms, which hydrocarbon group can contain one or more heteroatoms from the group N and O, and Rmeans a divalent hydrocarbon group having 3 to 12 carbon atoms, which hydrocarbon group can contain one or more heteroatoms from the group N and O, b is 0.1 or 2, c is 0.1, 2, or 3, d is 0.1 or 2, and n is 0.1 or 2, with the stipulation that the sum n+b+c+d is &#x2266;3, that at least one AKT group is contained per molecule on average, and that the organopolysiloxanes preferably form elastomeric films after the water is removed.  

Cosmetic compositions

Hair care compositions contain from 0.1 to 12 weight percent of a silicone copolymer or saponification product thereof, prepared from silicones, at least 10% of which contain polymerizable groups, 0.5-14% of hydrophilic comonomers, and 30-99.9% of hydrophobic comonomers. The compositions exhibit good hair care properties.
