FIELD: medicine, pharmaceutics. n SUBSTANCE: claim describes a cosmetic or dermatological composition in the form of cream, foam, spray, gel, gel spray, lotion, oil, oil gel or mousse. The composition contains at least one active substance, at least one molecular imprinted polymer in the presence of the same active substance, and at least one oil phase. The polymer contains a) a monoethylene-saturated mono- or dicarboxylic acid or α,β-ethylene-unsaturated mono- or dicarboxylic acid esters with diols and b) methacrylic acid esters of at least dihydric alcohols. The molar ratio of the compounds a) and b) makes 1:2 to 1:4, and the polymer is prepared in the medium of a solvent wherein monomers, but not the polymer to be prepared is dissolved in the presence of the active substance. n EFFECT: combination of the molecular imprinted polymer prepared by precipitative polymerization, and the oil phase provides the release of the active substance both in the water phase, and in the oil phase which ensures the best contact with a lipophilic surface, such as skin. n 3 cl, 3 dwg, 7 tbl, 37 ex |
