- 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.

Moreover, lithopone suppliers are expanding their product lines to offer variations of the pigment that meet specific market needs. Some suppliers provide specialized grades of lithopone that are tailored for particular applications, such as high gloss paints or specialty coatings. By offering these tailored solutions, suppliers can help paint manufacturers enhance the performance characteristics of their products, thus gaining a competitive edge in the market.
There are many uses of titanium dioxide that we don't know about because they were made exempt from being on the package in 1977, said Faber, who added that nothing much has changed since – other than the FDA approving some other uses of the color additive, such as expanding the use of mica-based pearlescent pigments (prepared from titanium dioxide) as color additives in distilled spirits over recent years.
Lithopone is the ideal combination of the white pigment zinc sulfide and the white spacer Blanc fixe. Due to the particle distribution of the ZnS (0.35 µm) and BaSO4 (0.8 -1.0 µm), which is the result of a co-precipitation (not mixing) and co-calcination, a high packing density is achieved, which in turn gives Lithopone its low resin demand and excellent rheological properties.
Some dealers quoted prices that were significantly higher than expected, sending the domestic market to an almost three-year high. Meanwhile, a similar scenario was observed in the Indian market, where titanium dioxide prices (rutile grade) for rose by 8% from January to March. The increase was attributed to strong demand from the domestic paints and coatings sector as well as premium cargo from China.
Lithopone is produced by coprecipitation of barium sulfate and zinc sulfide. Most commonly coprecipitation is effected by combining equimolar amounts of zinc sulfate and barium sulfide:
However, since it’s photosensitive — meaning it can stimulate free radical production — it’s usually coated in silica or alumina to prevent potential cell damage without reducing its UV-protective properties (7Trusted Source).

Throughout the fourth quarter of 2021, the European market had consistent optimistic sentiment. Despite the overwhelming inventories at lower levels during the fourth quarter of 2021, the demand prognosis in the domestic market revealed varied opinions. Imports from the Asia Pacific region, on the other hand, remained disruptive due to limited accessibility of vessel freights and a decrease in the PMI index for titanium dioxide in China despite the application of severe environmental protection measures.

If you want to avoid titanium dioxide, read labels carefully and stick to minimally processed whole foods.
Titanium dioxide nanoparticles are commonly found in a wide-range of consumer goods, including cosmetics, sunscreens, paints and colorings, ceramics, glass, textiles, construction materials, medicine, food, food packaging, and more. In Europe, cosmetic companies are required to label products that contain nanoparticles. In the U.S., companies are not.
