Titanium Dioxide is used to impart a whiteness to color cosmetics and personal care products that are applied to the skin (including the eye area), nails, lips, and it helps to increase the opacity, and reduce the transparency of a product formula. Titanium Dioxide also absorbs, reflects, or scatters light (including ultraviolet radiation in light), which can help protect products from deterioration. Titanium Dioxide is an important ingredient used in sunscreen products. Sunscreens are regulated by the Food and Drug Administration (FDA) as Over-The-Counter (OTC) drug products. As such, they must be demonstrated to be safe and effective in protecting the user from the harmful effects of ultraviolet radiation that is part of sunlight. - See more at: http://www.cosmeticsinfo.org/titanium-dioxide-information#sthash.i1flnWot.dpuf
