Titanium (IV) oxide is used as pigment to color paints, sunscreens, cosmetics, skin care products, plastics, papers, inks, medicines, toothpastes, and foods such as milk. It is also a thickener found in tattoo pigment and styptic pencils. It has UV resistant properties and is therefore used to act as a UV absorber.
