According to the EFSA's Expert Panel on Food Additives and Flavorings 2021 opinion regarding titanium dioxide, it could not rule out a concern for genotoxicity from ingestion of the material based on a perceived gap in data on this risk, which serves as the basis for current ban, said a March report on the decision.

When we purchase lithopone, we must pay attention to its ratio. This can be seen to some extent from the appearance. Basically, we can see that good  products are very delicate. , and the color is also very uniform, a kind of shiny white, while inferior lithopone has uneven particles and wrong luster.

Titanium dioxide is a food additive that can be found in over 3,000 different products in EWG’s Food Scores database.

As a widely used substance with multiple applications, research is being carried out to improve the production process to reduce the levels of chemicals used and waste produced, and to recycle any by-products.

On the other hand, the U.S. Food and Drug Administration (FDA) in their Final Administrative Order on Sunscreen Drug Products posted in September 2021 still accepts titanium dioxide up to 25% in the list of Generally Recognized As Safe and Effective (GRASE) in the main document, without further clarification on what kind or size of particles [9]. However, on page 24 (Sunscreen containing nanomaterials) FDA clearly “distinguish nanomaterials from other forms of these ingredients'' (zinc oxide and titanium dioxide) and ask for comments on “any particular nanomaterials that you believe should not be permitted for use in OTC sunscreen products”. To the best of our knowledge, this Agency did not ban the use of nanoparticulate titanium dioxide in any form, even though it is mentioned on page 34 that the anatase form is the more photoactive one, due to the lack of evidence with real sunscreens OTC (over the counter) in vivo. Moreover, other regulations in Latin America (MERCOSUR agreement, 2006) do not state clearly their position on the use of nanoparticulate TiO₂NPs [10].

In addition to its pharmaceutical applications, barium sulphate is extensively utilized in the production of paints and coatings, where a bright white pigment is essential. The opacity and brightness provided by barium sulphate make it a popular choice in formulations for white and colored paints. Its non-toxic nature and excellent stability enhance its appeal in these products.

The titanium dioxide (TiO2) industry supplier plays a crucial role in providing this essential material for a wide range of applications. TiO2 is a white pigment that is commonly used in paints, coatings, plastics, and paper, among other industries. The demand for TiO2 continues to grow as it is an important ingredient in products that require opacity, brightness, and UV protection.

Plus, titanium dioxide is chemically inert, meaning it won't react with other substances in the paint. This stability ensures that the paint retains its original color and properties over time, preventing discolouration and degradation. Using titanium dioxide as an ingredient, the paint can withstand harsh weather conditions and prevent flaking, peeling or chalking. This exceptional durability makes it ideal for interior and exterior walls, ensuring a long-lasting and beautiful finish.

Sensors

TiO₂ possesses different qualities depending on whether it is produced as a pigment or a nanomaterial. Both forms are tasteless, odourless and insoluble.
