Titanium is a common metal element frequently found throughout nature. In our environment, titanium is naturally exposed to oxygen, forming titanium oxides that we find in many minerals, dusts, sands, and soils.

Barium sulfide is produced by carbothermic reduction of barium sulfate. Zinc sulfate is obtained from a variety of zinc products, often waste, by treatment with sulfuric acid.

The element titanium and the compound TiO₂ are found around the world, linked to other elements such as iron, in several kinds of rock and mineral sands (including a component of some beach sands). Titanium most commonly occurs as the mineral ilmenite (a titanium-iron oxide mineral) and sometimes as the mineral rutile, a form of TiO₂. These inert molecular compounds must be separated through a chemical process to create pure TiO2.

This precipitate is not suitable for a pigment until it is filtered, dried, crushed, heated to a high temperature and quenched in cold water. The second heating in a muffle furnace at 725 °C produces crystals of the right optical size.

Titanium dioxide (TiO2) is a fine white powder or dust that occurs naturally. It was first intentionally produced for use as a white pigment in 1923.

Until relevant toxicological and human exposure data that would enable reliable risk assessment are obtained, TiO₂ nanoparticles should be used with great care.

Très apprécié dans le travail des Icônes pour éclaircir, mais également pour les vernis, émaux, peintures, plastique et papier. A l'inverse, ne pas utiliser ce produit dans les applications cosmétiques, comme additif alimentaire ou comme additif médicamenteux.

Mars Wrigley, the company that makes Skittles, is being sued by a California man who claims the candy contains a known toxin that poses such a serious health risk that Skittles are unfit for human consumption.

In June 2022, Health Canada weighed in on the debate, releasing a report on the safety of titanium dioxide. Their expert panel reviewed toxicity studies, including ones involving genetic damage. The expert panel found that previous studies used different forms and properties of titanium dioxide and deliberately broke the material into smaller particles than what you would normally see in food.

② Plastics: At present, it is the second largest user of titanium dioxide pigments, accounting for about 20% of the total demand for titanium dioxide. The amount of titanium dioxide used in plastic products will vary with the use requirements, generally between 0.5% and 5%. According to data from the National Bureau of Statistics, the production of plastic products in China increased from 57.81 million tons in 2012 to 81.84 million tons in 2019, with a compound annual growth rate of 5.1%. The amount of titanium dioxide increases accordingly.

Although the evidence for general toxic effects was not conclusive, on the basis of the new data and strengthened methods our scientists could not rule out a concern for genotoxicity and consequently they could not establish a safe level for daily intake of TiO₂ as a food additive.

Titanium dioxide is used in a wide range of food products and consumer goods – from candy to sunscreen and house paint. The U.S. Food and Drug Administration maintains that the regulated use of titanium dioxide, specifically as a color additive in food, is safe under some restrictions.
