Description and Uses
Benzoyl Peroxide may affect workers in the electronics and plastics (epoxy resins and catalysts) industries, electricians, ceramic workers, dentists and dental technicians, laboratory technicians and bakers. As it was contained in candles, it also induced contact dermatitis in a sacristan. However, some positive tests are of unknown occupational relevance.
Benzoyl Peroxide is a widely used organic compound of the peroxide family. It is used as a source offree radicals in many organic syntheses andto initiate polymerizations of styrene, vinylchloride, vinyl acetate, and acrylics; to curethermoset polyester resins and silicone rubbers;in medicine for treating acne; and forbleaching vegetable oil, cheese, flour, and fats.
