Titanium Dioxide is used in cosmetics, foods, crayons, fibers, papers, plastics and paints. In cosmetics it can be used as sunscreen, an opacifier and a white pigment. In sunscreen it can be used to effectively reflect UVB, UVA and UVC rays which means that this ingredient can be used in products to help prevent the premature aging of the skin and cancer. Titanium Dioxide is a physical sunblock and a broad spectrum sunscreen that scatters and absorbs light. In sunscreens that are manufactured for sensitive skin or infants, they will often contain either zinc oxide or titanium dioxide. This is because these mineral based UV blockers tend to be less likely to irritate the skin than other types of UV absorbing ingredients, such as the chemical UV absorber avobenzone.
