Titanium dioxide (TiO2) is renowned for its brightness, high refractive index, and stability. It comes in two primary crystalline forms rutile and anatase. Rutile is predominantly used in the production of tires due to its superior characteristics, including high UV resistance, durability, and excellent pigmentary properties. These features make TiO2 an ideal choice for enhancing the performance and longevity of tire products.

A 2012 study published in the journal Environmental Science & Technology noted that children are especially exposed to titanium dioxide because of the food that contains the food additive and is particularly marketed to children, including candy and cakes.
