The invention relates to the use of at least one copolymer obtainable by (i) free-radically initiated copolymerization of a monomer mixture comprising (a) 1 to 99.99% by weight of at least one monomer chosen from N-vinylimidazoles and diallylamines optionally in partially or completely quaternized
The invention relates to the use of at least one copolymer obtainable by (i) free-radically initiated copolymerization of a monomer mixture comprising (a) 1 to 99.99% by weight of at least one monomer chosen from N-vinylimidazoles and diallylamines optionally in partially or completely quaternized form; (b) 0 to 98.99% by weight of at least one neutral or basic water-soluble monomer which is different form (a); (c) 0 to 50% by weight of at least one unsaturated acid or unsaturated anhydride, (d) 0 to 50% by weight of at least one free-radically copolymerizable monomer which is different from (a), (b) or (c); and (e) 0.01 to 10% by weight of at least one monomer which acts as crosslinker and has at least two ethylenically unsaturated, nonconjugated double bonds; and (ii) subsequent partial or complete quaternization or protonation of the polymer in the case where the monomer (a) is unquaternized or only partially quaternized, as additive for skin cosmetic and dermatological preparations.

We claim: 1. In a skin cosmetic or dermatological preparation selected from cosmetic compositions for cleansing the skin, cosmetic compositions for the care and protection of the skin, nail care compositions, and preparations for decorative cosmetics, the improvement wherein the composition consists essentially of customary additives and at least one copolymer obtained by (i) free-radically initiated copolymerization of a monomer mixture comprising (a) 1 to 99.99% by weight of at least one monomer selected from the group consisting of N-vinylimidazoles and diallylamines, optionally in partially or completely quaternized form; (b) 0 to 98.99% by weight of at least one neutral or basic water-soluble monomer which is different from (a); (c) 0 to 40% by weight of at least one unsaturated acid or unsaturated anhydride, (d) 0 to 50% by weight of at least one free-radically copolymerizable monomer which is different from the monomers (a), from the monomers (b) and from the monomers (c); and (e) 0.01 to 10% by weight of at least one monomer which acts as crosslinker and has at least two ethylenically unsaturated, nonconjugated double bonds; and (ii) subsequent partial or complete quaternization and protonation of the polymer in the case where the monomer (a) is unquaternized or only partially quaternized. 2. The preparation as claimed in claim 1, wherein the protonation as in (ii) takes place during formulation of the preparation. 3. The preparation as claimed in claim 1, wherein monomer (a) is at least one diallylamine derivative of the formula (II), in which the radical R4 is C1-C24 alkyl. 4. The preparation as claimed in claim 1, wherein monomer (a) is at least one N-vinylimidazole derivative of the formula (I), in which the radicals R1 to R3 independently of one another are hydrogen, C1-C4-alkyl or phenyl. 5. The preparation as claimed in claim 1, wherein monomer (b) is at least one N-vinyllactam. 6. The preparation as claimed in claim 1, selected from the group consisting of cosmetic compositions for cleansing the skin. 7. The preparation as claimed in claim 6, selected from the group consisting of soaps, syndets, liquid washing, shower and bath preparations. 8. The preparation as claimed in claim 1, selected from the group consisting of cosmetic compositions for the care and protection of the skin, nailcare compositions, and preparations for decorative cosmetics. 9. The preparation as claimed in claim 8, selected from the group consisting of skincare compositions, personal hygiene care compositions, footcare compositions, sunscreens, repellents, shaving compositions, depilatories, anti-acne compositions, makeup, mascara, lipsticks, eyeshadows, kohl pencils, eyeliners, blushers, powders and eyebrow pencils. 10. The preparation as claimed in claim 9, wherein the skincare compositions are selected from the group consisting of water-in-oil or oil-in-water skin creams, day and night creams, eye creams, antiwrinkle creams, moisturizers, bleaching creams, vitamin creams, skin lotions, care lotions and moisturizing lotions. 11. The preparation as claimed in claim 1, wherein the copolymer is used in the form of a water-in-oil emulsion. 12. The preparation as claimed in claim 11, wherein the copolymer has been polymerized in the emulsion or suspension. 13. The preparation as claimed in claim 12, wherein the oil phase of the emulsion or suspension comprises a cosmetic oil. 14. The skin composition or dermatological preparation of claim 1 wherein a monomer mixture consisting of (a) 1 to 99.99% by weight of at least one monomer selected from the group consisting of N-vinylimidazoles and diallylamines, optionally in partially or completely quaternized form; (b) 0 to 98.99% by weight of at least one neutral or basic watersoluble monomer which is different from (a); (d) 0 to 50% by weight of at least one free-radically copolymerizable monomer which is different from the monomers (a), from the monomers (b), and from unsaturated acids and unsaturated anhydrides; (e) 0.01 to 10% by weight of at least one monomer which acts as crosslinker and has at least two ethylenically unsaturated, nonconjugated double bonds; is employed in the free-radical initiated copolymerization stage (i). 15. The skin composition or dermatological preparation of claim 1 wherein a monomer mixture consisting of (a) 1 to 99.99% by weight of at least one monomer selected from the group consisting of N-vinylimidazoles and diallylamines, optionally in partially or completely quaternized form; (b) 0 to 98.99% by weight of at least one neutral or basic water-soluble monomer which is different from (a); (c) 0 to 40% by weight of at least one unsaturated acid or unsaturated anhydride, (d) 0 to 50% by weight of at least one free-radically copolymerizable monomer which is different from the monomers (a), from the monomers (b) and from the monomers (c); and (e) 0.01 to 10% by weight of at least one monomer which acts as crosslinker and has at least two ethylenically unsaturated, nonconjugated double bonds; is employed in the free-radical initiated copolymerization stage (i).
