In a 2019 study published in the journal Nanotoxicology, researchers recreated the first phase of digestion in mice and fed them titanium dioxide, then examined whether accumulation occurred in the organs. Researchers wrote: “Significant accumulation of titanium was observed in the liver and intestine of E171-fed mice; in the latter a threefold increase in the number of TiO2 particles was also measured. Titanium accumulation in the liver was associated with necroinflammatory foci containing tissue monocytes/macrophages. Three days after the last dose, increased superoxide production and inflammation were observed in the stomach and intestine. Overall, [this] indicates that the risk for human health associated with dietary exposure to E171 needs to be carefully considered.”

Rutile titanium dioxide, the most common form of TiO2, possesses a tetragonal crystal structure and exhibits unique physical and chemical properties that make it suitable for a wide range of applications. One of the key advantages of rutile TiO2 is its high refractive index, which ranges from 2.4 to 2.7. This high refractive index enables rutile TiO2 to provide excellent hiding power and whiteness in coatings, plastics, and other materials.
