Abstract: Described are cosmetic preparations containing light-screening agents designed to protect the human epidermis against UV light in the region from 280 to 400 nm. The light-screening agents are contained in a carrier compound suitable for cosmetic purposes together with compounds of the formula (I), as given in claim 1, in which R1, R2 and n are as defined in clause 1, which absorb in the UV-B region and are per se prior art for cosmetic preparations, in amounts which are active as photostable UV-A filters.

Abstract: The invention pertains to the use of cross-linked copolymers produced by precipitation polymerization of monomer mixtures of: (a) monoethylenically unsaturated C3 to C8 carboxylic acids, their anhydrides or mixtures of said carboxylic acids and anhydrides, (b) compounds with at least two ethylenically unsaturated, non-conjugated double bonds in the molecule as cross-linking agents, and as needed; (c) other monoethylenically unsaturated monomers that are copolymerizable with monomers (a) and (b) in the presence of radical-forming polymerization initiators and, relative to the monomers used, 0,1 to 20 wt% saturated, nonionic surface-active compounds, as stabilizers in oil-in-water emulsions, in quantities of 0.01 to 5 wt% relative to the emulsions and in cosmetic and pharmaceutical preparations based on oil-in-water emulsions that contain said precipitation polymers.
