ti in tio2 factories

A few non-dietary studies have reported adverse effects in the gastrointestinal tract of laboratory animals given food-grade TiO2. However, these same effects were not seen when the same or higher doses of food-grade TiO2 were administered in the animals' diet. Dietary studies best reflect how humans are exposed to TiO2 from food. Thus, the Food Directorate placed the most emphasis on the results of these studies in the state of the science report.

Titanium dioxide, often referred to as TiO2, exists in two primary forms rutile and anatase. Rutile TiO2 is renowned for its exceptional optical properties and higher refractive index, making it the preferred choice for applications requiring maximum brightness and durability. This form of titanium dioxide is characterized by its dense particle structure, providing superior weatherability and resistance to discoloration, essential traits for products exposed to the elements.
