On September 2, 2011, California listed titanium dioxide (airborne, unbound particles of respirable size) (“TiO2″) 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 TiO2 when applying cosmetic, skin-care, and sun-protection powders to the face. PIA believes that cosmetic manufacturers — who use millions of tons of TiO2 annually in face and body powders to realize sales of billions of dollars — should be responsible and NOT use consumers as test subjects.
