titanium dioxide factories

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.”

For exterior wall paint materials, titanium dioxide plays a critical role in enhancing weather resistance. Its ultraviolet (UV) light absorption characteristics protect the binder system from degradation caused by sunlight exposure. As a result, paints containing titanium dioxide are less likely to fade, chalk, or crack under harsh environmental conditions. Moreover, its chemical stability prevents the pigment from reacting with other paint components, maintaining the integrity of the coating and extending its lifespan.
