Titanium dioxide safety is evaluated by regulatory agencies all over the world based on scientific studies.
Titanium dioxide has a number of unique characteristics that make it ideally suited to many different applications.
Lithopone is manufactured by a process (Fig. 1) in which barium sulfide solution is prepared by reducing barite ore (BaSO 4) with carbon and leaching the resulting mass.
The process of gravimetric analysis involves several steps. First, a sample containing titanium dioxide is dissolved in a suitable solvent. The titanium dioxide is then precipitated out of the solution in the form of a solid compound. This solid compound is then filtered, dried, and weighed to determine the amount of titanium dioxide present in the original sample.
China is a leading producer of titanium dioxide (TiO2), especially for masterbatch and plastic use. TiO2 is a white pigment widely used in various industries such as paints, plastics, paper, and cosmetics due to its excellent opacity and UV resistance.

We've used titanium dioxide safely for decades. However, recently its safety was called into question.
At CRIS, we've explored the safety of titanium dioxide for nearly half a decade, including conducting double-blind research to test the safety of food-grade titanium dioxide (E171). Our study shows that when exposed to food-grade titanium dioxide in normal conditions, research animals did not experience adverse health outcomes.
It's important to emphasize that in a National Institutes of Health study, experimental animals were exposed to titanium dioxide in amounts as high as 5% of their diet for a lifetime and showed no evidence of adverse effects.
A handful of studies greatly influenced the decisions made by the European Food Safety Authority (EFSA). Unfortunately, these studies did not consider that titanium dioxide exposure comes from food, not drinking water. Additionally, CRIS researchers could not reproduce the adverse outcomes identified by the studies through typical food ingestion. Regardless, the EFSA banned E171 as a food ingredient and for use in other capacities in the summer of 2022.
In 2022, the United States, United Kingdom, and Canada maintained that the scientific evidence supports that titanium dioxide (E171) is safe for humans to use and consume.
