Patent ID: 6932964

Claim:
A hair treatment composition comprising at least one water-soluble or water-dipersible polymer and a cosmetic auxiliary, wherein the polymer comprises, in copolymerized form, a) from 45 to 85% by weight of at least one α,β-ethylenically unsaturated monomer of the formula I in which R 1 is hydrogen or C 1 -C 8 -alkyl, and X 1 is O or NR 2 , where R 2 is hydrogen, C 1 -C 8 -alkyl or C 5 -C 8 -cycloalkyl, b) from 10 to 30% by weight of at least one α,β-ethylenically unsaturated mono- and/or dicarboxylic acid, c) from 1 to 20% by weight of at least one compound having at leat one α,β-ethylenically unsaturated double bond and at least 5 alkylene oxide units per molecule, chosen from polyether acrylates of the formula II in which the order the alkylene oxide units is arbitrary, k and l independently of one another are an integer from 0 to 50, the sum of k+1 being at least 5, R 3 is hydrogen or C 1 -C 8 -alkyl, and R 4 is hydrogen or C 1 -C 6 -alkyl, X 2 is O or NR 2 , where R 2 is hydrogen, C 1 -C 8 -alkyl or C 5 -C 8 -cycloalkyl, d) from 1 to 30% by weight of at least one compound having at least one α,β-ethylenically unsaturated double bond and at least one straight chain or branched C 8 -C 30 -alkyl or alkylene radical per molecule, chosen from compounds of the formula III in which R 5 is hydrogen or C 1 -C 8 -alkyl, R 6 is a straight-chain or branched C 8 -C 30 -alkyl radical, and Y is O or NR 7 , where R 7 is hydrogen, C 1 -C 8 -alkyl or C 5 -C 8 -cycloalkyl, where the components c) and/or d) can be partially or completely replaced by a component e), where e) is at least one compound having at least one ap-ethylenically unsaturated double bond, at least 5 alkylene oxide units and at least one straight-chain or branched C 8 -C 30 -alkyl or -alkylene radical per molecule, where component e) is chosen from e1) polyether acrylates of the formula II in which the order the alkylene oxide units is arbitrary, k and 1 independently of one another are an integer from 0 to 50, the sum of k+1 being at least 5, R 3 is hydrogen or C 1 -C 8 -alkyl, and R 4 is C 8 -C 30 -alkyl, X 2 is O or NR 2 , where R 2 is hydrogen, C 1 -C 8 -alkyl or C 5 -C 8 -cycloalkyl, e2) urethane (meth)acrylates containing alkylene oxide groups, and mixtures thereof, or salts thereof, and wherein the polymer is present in an effective amount to provide film-forming properties to the composition.
