In a review published in 2022 in the journal Archives of Toxicology, researchers found that the ingestion of E171 is a “a definite health risk for consumers and their progeny.” After reviewing dozens of in vivo, ex vivo and in vitro studies on the toxicity of E171, the researchers wrote that two facts must be noted: “First, reprotoxicity studies show that animals of both sexes are impacted by the toxicity of these nanoparticles, underlining the importance of conducting in vivo studies using both male and female animals. Second, human exposure begins in utero via maternal-fetal transfer and continues after birth by breastfeeding. Children are then chronically re-exposed due to their food preferences. To be relevant to the human in vivo situation, experimental studies should therefore consider nanoparticle exposure with respect to the age or life period of the studied population.”

The supply in North America remained adequate, as companies were seen constantly altering their production rates in response to the volatility in the demand pattern. In the final week of September, news of Chemours' forthcoming titanium dioxide factory in Georgia valued USD 86 million alleviated fears about supply strain.

According to the feedback of the manufacturers, the new mainstream factory has risen, and the focus of the overall market transaction has moved up. From the perspective of demand side, the current overall intention of the terminal to replenish inventory before the holiday is OK; From the supply side, some mainstream manufacturers have increased the load, and the actual output of the industry is stable. Most factories report a new price of around 17,000 yuan/ton, and some plastics and papermaking related downstream feedback some tight models are more expensive. Recent titanium dioxide raw material price trend is strong, titanium dioxide price support is more stable, comprehensive market factors, the current titanium dioxide market to maintain a price state.

One of lithopone's outstanding characteristics is its exceptional whiteness. The pigment has a brilliant white color that brings vibrancy and brightness to any application. Whether you are producing paints, coatings, plastics, rubber or printing inks, lithopone will ensure that your end product stands out with its unrivaled pure white shade.

The future of TiO₂

Scrap zinc or concentrated zinc ores are dissolved in sulfuric acid, the solution is purified and the two solutions are reacted. A heavy mixed precipitate results that is 28 to 30% zinc sulfide and 72 to 70% barium sulfate.

However, most dermatologists will warn their patients not to rely on mineral makeup alone in order to be protected by the sun’s rays. This is because there can be quite a bit of variation with mineral foundation – not only with how much we apply but how much titanium dioxide the foundation contains.
