In terms of sustainability, the use of rutile titanium dioxide in coatings aligns with the global push towards eco-friendliness. The product is non-toxic and, when combined with solvent-free formulations, can contribute to reduced volatile organic compound (VOC) emissions, making it a safer option for both the environment and those applying the coatings.
What titanium dioxide is really emblematic of ... is the failure of FDA to look back at these old decisions and ask whether its decisions that were made in this case ... 56 years ago (in the 1966 approval) still hold up, he said.
There’s also concern that exposure to the mineral over time, even in small amounts, can build up in the body, particularly in the kidneys, spleen and liver. Although most of the mineral is excreted in feces, there is evidence that a small percentage may remain in bodily organs.
Résumé–Cet article traite de la découverte de lithopone phosphorescent sur des dessins à l'aquarelle, datés entre 1890 et 1905, de l'artiste Américain John La Farge et de l'histoire du lithopone dans l'industrie des pigments à la fin du 19e et au début du 20e siècle. Malgré de nombreuses qualités souhaitables pour une utilisation en tant que blanc dans les aquarelles et les peintures à l'huile, le développement du lithopone comme pigment pour artistes a été compliqué de par sa tendance à noircir lorsqu'il est exposé au soleil. Sa disponibilité et son usage par les artistes demeurent incertains parce que les catalogues des marchands de couleurs n'étaient généralement pas explicites à indiquer si les pigments blancs contenaient du lithopone. De plus, lors d'un examen visuel, le lithopone peut être confondu avec le blanc de plomb et sa phosphorescence de courte durée peut facilement être ignorée par l'observateur non averti. À ce jour, le lithopone phosphorescent a seulement été documenté sur une autre œuvre: une aquarelle de Van Gogh. En plus de l'histoire de la fabrication du lithopone, cet article décrit le mécanisme de sa phosphorescence et son identification à l'aide de la spectroscopie Raman et de la spectrofluorimétrie.

As a key ingredient in solar panels, titanium dioxide helps to harness the power of the sun and convert it into clean energy As a key ingredient in solar panels, titanium dioxide helps to harness the power of the sun and convert it into clean energychina 98%min titanium dioxide anatase. By investing in the development of solar technology, China is not only reducing its reliance on fossil fuels but also helping to mitigate the effects of climate change.Matthew Wright, chair of the authority's working group on titanium dioxide, noted that the evidence for general toxic effects was not conclusive, but that the panel couldn't rule out genotoxicity entirely. There were also some current data limitations and the assessment could not establish a safe level for daily intake of the food additive, he stated.

The whole scientific experimental design in some of these studies is very flawed, Kaminski said.

Those scientists found that sunscreen residue on the roof installers fingertips were being transferred to the colour bond sheets during installation & with titanium dioxide’s photo-sensitivity & the lovely sun’s help, the paint was literally peeling off those roofs.
As of August 7, the use of titanium dioxide in food is banned in the European Union. Europe is taking a precautionary principle approach based on findings from the European Food Safety Authority (EFSA).
EFSA’s scientific advice will be used by risk managers (the European Commission, Member States) to inform any decisions they take on possible regulatory actions.
The updated evaluation revises the outcome of EFSA’s previous assessment published in 2016, which highlighted the need for more research to fill data gaps.
Other experts say there is simply no conclusive evidence at this point that titanium dioxide is damaging to humans after ingesting. Kaminski in particular said the research studies cite health hazards that were found by using high doses of the product, which you would not normally see in food.
An inorganic chemical, titanium dioxide is used as a dye to help products achieve a certain appearance, including whitening a product. Some experts and publications have described it as being akin to a paint primer that's used before the color is added to food in order to give products a uniform shine. Its presence is common in many items beyond Skittles including coffee creamers, cake mixes, and chewing gum. It's also used for pigment and in cosmetics manufacturing.
BaS+ZnSO4→ZnS·BaSO4
Le produit obtenu par cette méthode est constitué de 29,4 % en masse de ZnS et 70,6 % en masse de BaSO4. Il existe des variations, par exemple l'adjonction de chlorure de zinc à la pâte avant chauffage produit un pigment plus riche en ZnS3.
