titanium dioxide over the counter manufacturer

At the present JECFA meeting, the committee considered additional toxicological studies relevant to the safety assessment of the chemical that investigated its toxicokinetics, acute toxicity, short-term toxicity, long-term toxicity and carcinogenicity, genotoxicity, and reproductive and developmental toxicity, as well as special studies addressing its short-term initiation/promotion potential for colon cancer. The experts acknowledged that a large number of toxicological studies have been conducted using test materials, including nanoparticles, having size distributions and physico-chemical properties not comparable to real-world uses of titanium dioxide as a food additive. The studies on non-representative materials were evaluated by JECFA, but the committee concluded that such studies are not relevant to the safety assessment of the additive.

Anatase and rutile nano-TiO2 differ primarily in their crystal structures, which endows them with distinct characteristics. Anatase is recognized for its higher surface area and superior photocatalytic activity, making it ideal for applications such as air purification and water treatment. On the other hand, rutile boasts greater stability and refractive index, positioning it perfectly for uses in paints, plastics, and sunscreens.
