What is titanium dioxide and why is it used in sunscreen and cosmetics?
A metallic mineral, titanium dioxide is used as a sunscreen and color pigment. Micronized titanium dioxide, a very finely ground form, is used in sunscreens for its broad-spectrum sun protection. Micronization is achieved through mechanical grinding not nano engineering. Numerous studies confirm it is non-toxic and non-irritating, is not absorbed by the skin, and has found no evidence of carcinogenicity or other toxicity.
