Titanium Dioxide and cosmetics


What Is Titanium Dioxide?
Titanium Dioxide is a naturally occurring mineral derived from oxide of titanium. 
The oxides are typically mined and then further processed and purified for use in consumer products.
Why is it used in cosmetics and personal care products?
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.
Is Titanium Dioxide a safe ingredient for use in cosmetics and personal care products?
The FDA has assessed the safety of Titanium Dioxide as a color additive for use in foods, drugs and cosmetics and has issued regulations approving the ingredient for these purposes.
What about Titanium Dioxide and nanoparticles?

Some personal care products may contain nanoscale particles of titanium dioxide and zinc oxide that are used as active ingredients in sunscreen products and have been approved for use by the Food and Drug Administration (FDA) since 1999. These nanoscale particles have been developed by breaking down larger particles during the manufacturing process. Titanium Dioxide and Zinc Oxide have been extensively evaluated and the scientific data shows that they do not penetrate the skin.
