Titanium(IV) oxide (titanium dioxide) is widely used as a white pigment in paints, coatings, plastics, paper, inks, rubber, ceramics, cosmetics, and food applications (where regulatory grade permits). It is also employed as a UV absorber, photocatalyst, catalyst support, polishing material, electronic ceramic raw material, and pharmaceutical excipient.
