The use of copolymers obtainable by the radically initiated polymerization of A) 50 to 99.9 wt % of an olefinically unsaturated C3 to C5 monocarboxylic acid, an olefinically unsaturated C4 to C8 dicarboxylic acid or its anhydride, or a mixture of such carboxylic acids or carboxylic acid anhydrides with B) 0.1 to 50 wt % of one or more long-chained compounds with isolated multiple C&#x2014;C bonds from the group (1) mono or polyunsaturated C8 to C30 monocarboxylic acids which may have additional hydroxyl groups and their alkaline metal and earth alkaline metal salts, alkyl esters, amides, sorbitane esters, glycerin esters and polyglycerin esters, (2) mono or polyunsaturated aliphatic Ca to C30 amines, (3) mono or polyunsaturated C8 to C30 alcohols and esters thereof with saturated Cl to C4 monocarboxylic acids, (4) to (C8 to C30 alkyl) vinyl ether which may incorporate up to 25 alkylene oxide units, and (5) final and medium-position Ci3 to C30 alkenes; C) 0 to 49.9 wt % of other copolymerizable monomers, and D) 0 to 10 wt % of one or more compounds with at least two olefinically unsaturated groups in the molecule as cross-linking agents, as thickening or dispersing agents, especially in cosmetic and pharmaceutical preparations.

Use of copolymers of carboxylic acids and long-chain compounds with isolated C-C multiple bonds as thickeners or dispersants

An ascorbic acid derivative of the formula Ia:where the variables independently of one another have the following meanings:

Cosmetic and pharmaceutical preparations comprising ascorbic acid derivatives

Use of substituted vinyl-tetrahydronaphthalenes and vinyl-benzotetrahydropyrans as light protection agents

Use of cyclic enamines as light protection agents

Cosmetic and pharmaceutical preparations containing photostable UV filters

The present invention describes the use of finely divided dye-containing polymers PD in the form of an aqueous polymer dispersion or a polymer powder obtainable therefrom, the polymer matrix of which comprises at least one organic dye D in homogeneously dispersed form, as color-imparting constituent in cosmetic compositions. The present invention also describes cosmetic compositions which comprise a color-containing polymer in an amount of from 0.1 to 50% by weight, based on the total weight of the cosmetic composition, and additives customary for cosmetic compositions.

Use of finely divided dye-containing polymers PD as color-imparting constituent in cosmetic compositions

Use of crosslinked copolymers of monoethylenically unsaturated carboxylic acids as stabilizer in oil-in-water emulsions

Use of substituted vinyltetrahydronaphthalenes and vinyl-benzotetrahydropyrans as light protection agents

Oligomeric diarylbutadienes

Use of amino-substituted hydroxybenzophenones as photostable UV filters in cosmetic and pharmaceutical preparations

Photo-stable cosmetic and pharmaceutical formulations containing UV-filters

Copolymers of carboxylic acids and quaternary ammonium compounds and the use thereof as thickeners of dispersants
