Stable cosmetic and dermatological light-protecting preparations in the

Active compound combinations, which have a light protection action, of 4,4',4'-(1,3,5-triazine-2,4,6-triyltriimino)-trisbenzoic acid tris(2-ethylhexyl ester) and one or more emulsifiers chosen from the group of substances of the general structural formula wherein R.sub.1, R.sub.2 and R.sub.3 independently of one another are chosen from the group which comprises: H and branched and unbranched, saturated and unsaturated fatty acid radicals having 8 to 24 carbon atoms, in which up to three aliphatic hydrogen atoms can be replaced by hydroxyl groups, and n is a number from 2 to 8.

Cosmetic and dermatological light protection formulations having a

Use of (a) one or more cosmetically or pharmaceutically acceptable hydrophobic inorganic pigments for achieving or increasing the water resistance of cosmetic or dermatological light protection formulations which are in the form of O/W emulsions or W/O emulsions, (b) the hydrophobic inorganic pigments being incorporated into the oily phase of the O/W emulsions or W/O emulsions, and comprise (c) one or more UV filter substances which carry one or more sulphonic acid groups or sulphonate groups on their molecular skeleton, and (d) one or more surface-active substances chosen from the group consisting of glucose derivatives and which (e) are essentially free from polyethoxylated emulsifiers.

Water-resistant light protection formulations having a content of

Cosmetic or pharmaceutical O/W emulsions which contain

Stable light protection preparations containing surface-active glucose

Foaming light protection preparations containing water-soluble light
