STABLE SOLUBLE SALTS OF PHENYLBENZIMIDAZOLE SULFONIC ACID AT PHS AT OR BELOW 7.0

The invention concerns preparations, particularly cosmetic or pharmaceutical/dermatological preparations, containing phenylbenzimidazole sulfonic acid (i.e. 2-phenylbenzimidazole-5-sulfonic acid) neutralised with basic amino acids such as arginine, lysine, ornithine and histidine so that the pH of the preparation can be at or below 7.0 without incurring crystallisation of the phenylbenzimidazole sulfonic acid.

Coated pigment and cosmetic materials comprising the same

Pigments coated with metallic soap and containing water easily disperse in the water and yet demonstrate water-repellency. The present pigments will thus obtain cosmetic which will give the user a refreshment and longer lasting and water-repellent make-up.
