Titanium Dioxide is a naturally occurring earth mineral also known as Titania or TiO2, and is the naturally occurring oxide of
titanium and the ninth most common mineral on planet earth.
TiO2 is a Common Earth Mineral - It takes four forms:
The most common crystalline structure. The densely packed crystals of rutile TiO2 reflect light well and are used as pigments and sun blockers. Global sales exceed $4.5billion per year.
Rarer anatase TiO2 has a more open crystal structure, is highly photocatalytic and the core of Titanium Dioxide Coatings technology. Rutile TiO2 Anatase TiO2
Extremely rare and unstable. No commercial usage.
a non-crystalline form of Titania used to form adhesive and protective mineral films known as TioxoGuard.
TiO2 is widely used - Applications include:
- Pigment - a typical gallon of paint contains one and a half pounds of TiO2
- Sunscreen - High SPF sun tan lotions contain 8% to 25% TiO2
- Food Additive - White aspirin tablets contain 2% TiO2
TiO2 is Safe
- TiO2 is a non-toxic, inert mineral found in nature that has been classified by the US FDA as "GRAS" or "Generally Recognized as Safe".
- The US FDA has approved TiO2 for use in food and materials as a "whitening agent" and in skin creams and lotions as a "sun-blocking agent".
- The European Science Commission on Cosmetics and Food Products has found TiO2 to be safe in all forms (micronized and nanosized, active and inactive) for human use and consumption.
