BenzophenonesUpdated a month ago

(Additional Names: Benzophenone-1, Benzophenone-2, Benzophenone-3 aka Oxybenzone, Benzophenone-4, Benzophenone-5, Benzophenone-6 Benzophenone-8, Benzophenone-9, Benzophenone-11, Benzophenone-12)

Benzophenones are photostabilizers used in cosmetics. Photostabilizers have a photoprotective effect on the skin. In 2012, benzophenone was added as a carcinogen to the California EPA’s Proposition 65 List of Chemicals Known to the State to Cause Cancer or Reproductive Toxicity. The evidence linking the benzophenone chemicals to endocrine disruption is complex, and studies show that different benzophenones may have difference hormone-disrupting effects. Because they commonly cause contact allergic dermatitis, benzophenones were declared the Contact Allergen of the Year for 2014 by the American Contact Dermatitis Society (ACDS).
