Description

White solid; Insoluble in water; [IARC] Powder; [Sigma-Aldrich MSDS]

Sources/Uses

A naturally occurring crystalline form of titanium dioxide obtained from processing ilmenite (a natural iron titinate) or titanium slag; Used as a whitening and opacifying agent in paints, paper, ceramics, and enamels; [IARC] Used for specialized white pigment applications such as paper and fibers; TIO2 is also used in welding rod coatings; Anatase is a semiconductor, and it is used to make electronic components; [Reference #1]

Comments

Not a skin irritant; [IUCLID] "NIOSH has determined that ultrafine TiO2 is a potential occupational carcinogen but that there are insufficient data at this time to classify fine TiO2 as a potential occupational carcinogen." Summary of Epidemiologic Studies: "Overall, these studies provide no clear evidence of elevated risks of lung cancer mortality or morbidity among those workers exposed to TiO2 dust." [Reference #1] A skin and strong eye irritant; Toxic by inhalation; [Sigma-Aldrich MSDS] See "Titanium dioxide."
