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.).

When looking for the best rutile titanium dioxide supplier, it is important to conduct thorough research and due diligence. This includes reviewing the supplier's credentials, certifications, and customer reviews. It is also advisable to request samples of the product to test its performance and compatibility with specific applications. By taking these steps, you can ensure that you are working with a reliable and reputable supplier that can meet your titanium dioxide needs.

In the world of pigments, titanium dioxide stands tall as a favorite material for its ability to provide brilliant whiteness and exceptional opacity. Its refractive index is high, making it ideal for achieving that pure, lustrous look in paints and coatings. But its capabilities don’t end there; titanium dioxide is also prized for its stability and resistance to discoloration, ensuring longevity in artistic creations and protective layers.

In a 2017 study published in Scientific Reports, researchers exposed rats to human-relevant levels of E171 to examine the effects of intestinal inflammation and carcinogenesis. They saw that “a 100-day E171 treatment promoted colon microinflammation and initiated preneoplastic lesions while also fostering the growth of aberrant crypt foci in a chemically induced carcinogenesis model.” They continued: “Stimulation of immune cells isolated from Peyer’s Patches [which are clusters of lymphoid follicles found in the intestine] showed a decrease in Thelper (Th)-1 IFN-γ secretion, while splenic Th1/Th17 inflammatory responses sharply increased,” researchers wrote. “A 100-day titanium dioxide treatment promoted colon microinflammation and initiated preneoplastic lesions.” The scientists concluded: “These data should be considered for risk assessments of the susceptibility to Th17-driven autoimmune diseases and to colorectal cancer in humans exposed to TiO2 from dietary sources.”
