Octinoxate (Additional Names: Octyl Methoxycinnamate or Ethylhexyl Methoxycinnamate)
A UV filter protecting the skin from UVB rays. It penetrates the skin and has been found in mother’s milk. Studies have shown that it may have some weak hormone-mimicking effects. More studies are needed to determine its long-term health effects on humans.
Oxybenzone (Additional Names: Benzophenone-3)
A UV filter to protect against UVB and short UVA rays. The National Health and Nutrition Survey has found it to be present in 96.8% of human urine samples surveyed. 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 benzophenone to endocrine disruption is complex, and studies show that different types of benzophenones may have different 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).
