Benzophenone-4 (inci)

Benzophenone-4 is used as a light protection agent in cosmetics. In combination with UV the substance may cause a light sensitization (photo contact allergy) (see photo allergy below).

There is evidence that benzophenone is absorbed in relevant quantities when applied over large areas and excreted via the kidneys.
