June 12, 2013, San Francisco, CA — On June 12, 2013, the Public Interest Alliance served 60-day notices of violation of California’s Proposition 65 on 60 manufacturers of cosmetic, skin-care, and sun-protection products for failure to provide clear and reasonable warning of exposure to titanium dioxide (airborne, unbound particles of respirable size). On September 2, 2011, California listed titanium dioxide (airborne, unbound particles of respirable size) as a chemical known to the state to cause cancer. Beginning September 2, 2012, manufacturers of products that expose people to titanium dioxide (airborne, unbound particles of respirable size) have been required by Proposition 65 (the Safe Drinking Water and Toxic Enforcement Act of 1986, Cal. Health & Safety Code section 25249.6) to provide a clear and reasonable warning in connection with any sale or offer to sell such products. Recently published peer-reviewed scientific studies have demonstrated what common sense would suggest: Consumers are exposed to titanium dioxide particles of respirable size when applying cosmetic, skin-care, and sun-protection powders to the face.
