For research published in 2022 study in the journal Food and Chemical Toxicology, scientists examined “the genotoxicity and the intracellular reactive oxygen species induction by physiologically relevant concentrations of three different TiO2 nanomaterials in Caco-2 and HT29-MTX-E12 intestinal cells, while considering the potential influence of the digestion process in the NMs’ physiochemical characteristics.” They found a “DNA-damaging effect dependent on the nanomaterial,” along with the micronucleus assay suggesting “effects on chromosomal integrity, an indicator of cancer risk, in the HT29-MTX-E12 cells, for all the tested TiO2 nanomaterials.” Researchers concluded that the results showcase “evidence of concern” regarding titanium dioxide used as a food additive.

Rutile, the most common form of titanium dioxide, is a reddish-brown pigment with a high refractive index and excellent weathering resistance. It is mainly used in paints, coatings, plastics, and paper industries due to its ability to provide excellent whiteness, opacity, and UV protection. Rutile titanium dioxide is typically produced by the sulfate process, which involves the reaction of titanium ore with sulfuric acid to produce titanium sulfate. The resulting solution is then treated with ammonia to precipitate titanium hydroxide, which is subsequently calcined at high temperatures to obtain rutile titanium dioxide.

Despite a bullish trends ruling the market for the bulk of the period, the North American market had mixed sentiments in the fourth quarter of 2021. This was mostly due to the adequate pushback from the supply-demand imbalance, which was further compounded by rising natural gas prices, which had taken a proper toll on the future production of numerous minerals, including titanium dioxide. An increase in COVID instances had prompted concerns in ore feedstock. As a result, during the fourth quarter of 2021, the FD UGSC (USA) quarterly average negotiations for the chemical CP Rutile Grade were finalised at USD 4434 per tonne.
