wholesale industrial grade titanium dioxide

Titanium dioxide, often referred to as TiO2, exists in two primary forms rutile and anatase. Rutile TiO2 is renowned for its exceptional optical properties and higher refractive index, making it the preferred choice for applications requiring maximum brightness and durability. This form of titanium dioxide is characterized by its dense particle structure, providing superior weatherability and resistance to discoloration, essential traits for products exposed to the elements.

In a study published in the journal Toxicology, researchers examined the effects of exposing human colon cancer cell line (HTC116) titanium dioxide food additives in vitro. “In the absence of cytotoxicity, E171 was accumulated in the cells after 24 hours of exposure, increasing granularity and reactive oxygen species, inducing alterations in the molecular pattern of nucleic acids and lipids, and causing nuclei enlargement, DNA damage and tubulin depolymerization,” the scientists wrote. Researchers removed the additive from the culture, then examined the results 48 hours later. They found, “The removal of E171 was unable to revert the alterations found after 24 h of exposure in colon cells. In conclusion, exposure to E171 causes alterations that cannot be reverted after 48 h if E171 is removed from colon cells.”

One of the key factors to consider when choosing a supplier for brilliant blue FCF and titanium dioxide is the quality of their products. Suppliers should provide detailed information about the purity and composition of their dyes and pigments, as well as any potential impurities or contaminants that may be present. Additionally, suppliers should have proper documentation and certifications to demonstrate the safety and compliance of their products.

In 2021, the European Food Safety Authority concluded that titanium dioxide is no longer safe in foods due to the same concerns over nanoparticles. As a result, titanium dioxide is now banned as a food additive in the EU. Although studies have shown that the absorption of ingested titanium dioxide is low, evidence suggests that titanium dioxide nanoparticles can accumulate in the body over time. Health Canada deemed it safe in 2022 but noted concerns. Unlike their European counterparts, Canadian officials did not consider studies performed with titanium dioxide nanoparticles alone.
