The present invention is directed to protecting human and animal hair and skin from the damaging effects of UV radiation. (b) p-aminobenzoic acid derivatives, salicylic acid derivatives, benzophenone derivatives, diphenyl acrylate derivatives, benzofuran derivatives, polymer UV absorbers comprising at least one organosilicon radical, cinnamic acid derivatives, camphor derivatives, s-trees Fat-soluble organic UV absorbers selected from the class of azine derivatives, trianilino-s-triazine derivatives, menthyl anthranilate and benzotriazole derivatives In the presence of (a) a polymer carrier prepared by heterogeneous radical polymerization of one or more ethylenically unsaturated monomers And a weight ratio of the fat-soluble organic UV absorber (b) to the polymer carrier (a) is more than 50 parts of the UV absorber per 100 parts of the carrier, the use of the concentrated aqueous polymer dispersion having an average particle size of less than 1000 nm. The concentrated aqueous polymer dispersion shows unexpectedly high sunscreen effect and positive skin feel. |
