Titanium dioxide has been deemed safe by the FDA for use in sunscreens, food colorant and cosmetics, as of 2014. Titanium dioxide is one of the most common minerals in the world and is most often used in sunscreen.
Titanium dioxide deflects light. This makes it a popular additive for sunscreens because of its ability to keep away harmful UV rays. Titanium dioxide is often used in cosmetic products such as lipstick, toothpaste, creams and powders. Its purpose is to make the pigment of these products more opaque. Titanium dioxide is considered a safe pigment to use in cosmetics when it is 99 percent pure, according to the FDA. No adverse effects have been recorded when titanium dioxide is properly manufactured.
