Yes. According to the FDA and other regulatory agencies globally, “titanium dioxide may be safely used for coloring foods”. Titanium dioxide is safe to use, and the FDA provides strict guidance on how much can be used in food. The amount of food-grade titanium dioxide that is used is extremely small; the FDA has set a limit of 1 percent titanium dioxide for food. There is currently no indication of a health risk at this level of exposure through the diet.

The National Cancer Institute tested TiO2 for possible carcinogenicity by the oral route of exposure by feeding rats and mice with TiO2 (size not specified) at doses 25,000 or 50,000 ppm TiO2 for 103 weeks. They concluded that TiO2 was not carcinogenic.Also, the study with rats fed diets containing up to 5 % TiO2 coated mica for 130 weeks showed no treatment-related carcinogenicity. Since the size and other TiO2 properties were not specified or determined, we cannot generalize this conclusion and we have to take into account other possible outcomes of this scenario in different exposure conditions (other size/crystalline structure of TiO2 etc.).

Aside from its optical properties, TiO2 boasts excellent stability under various environmental conditions. It does not decompose when exposed to sunlight or react with other ingredients in formulations. This chemical inertness makes TiO2 a reliable choice for both indoor and outdoor applications, where resistance to UV radiation and weathering is crucial This chemical inertness makes TiO2 a reliable choice for both indoor and outdoor applications, where resistance to UV radiation and weathering is crucial This chemical inertness makes TiO2 a reliable choice for both indoor and outdoor applications, where resistance to UV radiation and weathering is crucial This chemical inertness makes TiO2 a reliable choice for both indoor and outdoor applications, where resistance to UV radiation and weathering is crucialtio2 for pigment manufacturer. Manufacturers can thus create products with longer shelf lives and improved durability without compromising on performance or safety standards.
