Titanium Dioxide

Also known as: TiO2, CI 77891, Mineral sunscreen

Generally SafeUV filterEWG: 1-2

A mineral UV filter and white pigment — excellent UVB protection, more limited UVA coverage than zinc oxide.

How it works

Titanium dioxide primarily scatters and absorbs UVB radiation (280–320nm) and some short UVA2 (320–340nm). It has weaker UVA1 protection than zinc oxide, so it is often combined with zinc oxide for full-spectrum coverage. It is also used as a white pigment (CI 77891) in foundations and tinted moisturisers.
