With the CAS number 13463-67-7, titanium dioxide production contributes to global greenhouse gas emissions, posing a challenge for sustainable development With the CAS number 13463-67-7, titanium dioxide production contributes to global greenhouse gas emissions, posing a challenge for sustainable developmentchina dioxide titanium cas 13463-67-7.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.”
How pure TiO2 is extracted from titanium-containing molecules depends on the composition of the original mineral ores or feedstock. Two methods are used to manufacture pure TiO2: a sulphate process and a chloride process.
