摘要
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 crystallization of the phenylbenzimidazole sulfonic acid.
