Claims
- 1. A polymer suitable for use in hair styling compositions, said polymer being obtained by free radical copolymerization of a monomer mixture comprising
- (a) from 7 to 20% bu weight of a 1-vinylimidazole or of a quaternized 1-vinylimidazole,
- (b) from 40 to 60% by weight of N-vinylcaprolactam,
- (c) from 20 to 50% by weight of N-vinylpyrrolidone and
- (d) from 0 to 15% by weight of a further monomer which is capable of free radical copolymerization and, as a homopolymer, has a glass transition temperature of more than 20.degree. C., which further monomer is selected from the group consisting of C.sub.1 -C.sub.12 -alkyl esters of acrylic or methacrylic acid, acrylamides,
- and methacrylamides, and, if an unquaternized 1-vinylimidazole is used as monomer (a), subsequent quaternization of the polymer.
- 2. A polymer as defined in claim 1, containing 3-methyl-1-vinylimidazolium chloride or methylsulfate as monomer (a).
- 3. A polymer as defined in claim 1, containing 3-ethyl-1-vinylimidazolium ethylsulfate as monomer (a).
- 4. A polymer as defined in claim 1, containing tert-butyl acrylate as monomer (d).
- 5. A cosmetic hair formulation containing a polymer as defined in claim 1 as an active ingredient.
- 6. A cosmetic hair formulation as defined in claim 5, in the form of an aerosol foam.
- 7. A cosmetic hair formulation as defined in claim 5, in the form of a pump foam.
- 8. A cosmetic hair formulation as defined in claim 5, in the form of a gel.
- 9. A cosmetic hair formulation as defined in claim 5, containing, in addition to the polymer as an active ingredient, further polymers conventionally used in hair cosmetics.
- 10. A cosmetic hair formulation as defined in claim 5, containing the assistants conventionally used in hair cosmetics.
- 11. A cosmetic skin formulation containing a polymer as defined in claim 1 as an active ingredient.
- 12. A polymer as defined in claim 1 obtained by copolymerization of a monomer mixture comprising
- (a) from 7 to 20% by weight of a 1-vinylimidazole quaternized with dimethyl sulfate or dimethyl sulfate,
- (b) from 40 to 60% by weight of N-vinylcaprolactam and
- (c) from 20 to 50% by weight of N-vinylpyrrolidone.
- 13. A polymer suitable for use in hair styling compositions, said polymer being obtained by free radical copolymerization of a monomer mixture comprising
- (a) from 5 to 10% by weight of a 1-vinylimidazole or of a quaternized 1-vinylimidazole,
- (b) from 45 to 80% by weight of N-vinylcaprolactam,
- (c) from 20 to 50% by weight of N-vinylpyrrolidone and
- (d) from 1 to 5% by weight of a further monomer which is capable of free radical copolymerization and, as a homopolymer, has a glass transition temperature of more than 20.degree. C.
- and, if an unquaternized 1-vinylimidazole is used as monomer (a), subsequent quaternization of the polymer.
