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.
They are the only two sunscreen ingredients classified by the FDA as safe and effective. And though titanium dioxide is usually used in mineral sunscreens in the form of nanoparticles, evidence suggests that few, if any, particles penetrate the skin.
It is suitable as an alternative to titanium dioxide when higher acid resistance is required, such as in adhesive joints and sealants.
In the automotive industry, for example, MBR9668 is used in primers and finish coats to provide superior color retention and gloss. With durability being a key concern for automotive manufacturers, utilizing rutile titanium dioxide in coatings enhances the longevity of the vehicle's exterior finishes, ensuring that they remain vibrant and effective for years under various conditions.
