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.”

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.

  • Thusfive hundred and sixty-three pounds of a seventeen-per-ccnt. grade of lithopone will be precipitated, from which the soda liquor may be filtered and then washed out. Fifty six pounds of sodium hydrosulfid may then be recovered from the solution, if no further treatment thereof is contemplated, by any suitable evaporating process. By employing sodium sulfate and suitably altering the reaction I have also produced lithopone and sogo dium sulfid. The products of these reactions will be found to be of unusual purity and require no subsequent treatment for placing them upon the market.
