Titanium dioxide (TiO2) is a white inorganic compound found naturally as the mineral rutile. It is used as a pigment for its bright white color and opacity, as well as its resistance to discoloration. TiO2 has many other uses, including use in cosmetics, sunscreen, food coloring, and paper production. It is also used in the manufacture of ceramics and glass products. The most common form of TiO2 is anatase which has a crystalline structure that gives it excellent whiteness and brightness properties. It is also highly resistant to UV light which makes it ideal for outdoor applications such as paints and coatings.
