- Furthermore, the concept of green chemistry is gaining traction in the Chinese TiO2 industry. Companies are exploring eco-friendly production methods, such as using chloride-route technology that generates less wastewater and has a lower environmental impact compared to the traditional sulfate route.

Pendant longtemps on a reproché au lithopone sa mauvaise tenue à l'extérieur, due à la dégradation photolytique du sulfure de zinc et/ou à la présence de traces de chlore, provoquant un noircissement du revêtement. Même si la recherche a permis d'éradiquer en grande partie ce problème, on réserve son emploi dans les peintures intérieures pour les raisons suivantes :
In addition, lithopone has a strong hiding power beyond zinc oxide. This means less lithopone will have greater coverage and masking power, saving you time and money. No need to worry about multiple coats or uneven finishes anymore - the hiding power of lithopone ensures a flawless, even look in a single application.

- Another essential application of titanium dioxide is in the manufacture of plastics. It enhances the strength and durability of the polymer matrix while improving its resistance to UV radiation. This makes it an excellent additive for outdoor products such as garden furniture, automotive parts, and roofing materials, where exposure to sunlight can cause deterioration over time.
While the conclusions of the EU expert panel were considered in this report, Health Canada's Food Directorate conducted its own comprehensive review of the available science. This included evaluating new scientific data that addressed some of the uncertainties identified by the EU expert panel and were not available at the time of their review.
- On the other hand, the sulfate process involves treating ilmenite ore with sulfuric acid to produce titanyl sulfate solution, which is then calcined to produce titanium dioxide. This method produces lower-quality titanium dioxide with a higher impurity level, making it less expensive than the chloride process. However, the sulfate process is more commonly used due to its lower cost and higher yield.

- China is known for being one of the largest producers and consumers of titanium dioxide (TiO2) in the world. TiO2 is a white pigment that is commonly used in paints and inks due to its excellent opacity, brightness, and UV protection properties.
In 2017, French researchers from the Institut National de la Recherche Agronomique (INRAE) were among the first to examine the effects of E171 nanoparticles on the body. They fed rats a dose of 10mg of E171 per kilogram of body weight per day, which was similar to human exposure in food. The research, which was published in Scientific Reports, showed that E171 was able to traverse the intestinal barrier, pass into the bloodstream, and reach other areas of the body in rats. Researchers also found a link between immune system disorders and the absorption of titanium dioxide nanoparticles.
What are the different forms of titanium dioxide in beauty and personal care products?
- Anatase titanium dioxide pigment is a popular choice for manufacturers in a variety of industries, including paints, coatings, plastics, and cosmetics. This high-quality pigment is valued for its superior opacity, brightness, and UV resistance, making it an ideal choice for products that require long-lasting color and protection.
Is titanium dioxide illegal in other countries?
Titanium dioxide comes in the form of a white powder and is sometimes used in cosmetics to adjust a color to a lighter shade. This is also why it can produce a white cast.
Zn + n NH 3 + 2H 2 0→ [Zn NH 3 n] 2+ + H 2 + 20H— (unreacted zinc powder in the replacement slag) ZnS0 4 + n NH 3 → [Zn (NH 3 ) n ] 2+ +S0 4 2 —20 Patented Dec. 15, 1931 UNITED STATES PATENT OFFICE WILLIAM J. O'BRIEN, 0F BALTIMORE, MARYLAND, ASSIGNOR, BY MESNE ASSIGNMENTS,For those wishing to limit or avoid exposure to titanium dioxide in foods, there are some steps you can take.
The report can also be customized based on the requirement of the customer The reaction liquid is filtered through plate and frame pressure to obtain lithopone in the form of a filter cake with a moisture content of no more than 45%. It is then roasted in a drying furnace to change the crystal form of lithopone, and is then pickled with sulfuric acid at a temperature of 80°C. Finally, it is washed with water, reinforced with colorants, filtered, dried and ground into powder.
In 2022, a year after the EFSA recommended against the use of E171, the Food Standards Australia New Zealand (FSANZ) conducted its own reassessment of titanium dioxide as a food additive. The agency concluded that titanium dioxide was indeed safe to use as a food additive. The United Kingdom and Canada came to similar conclusions.
Titanium dioxide is used in an enormous range of food products, which can feel jarring when looking at some of its other uses.

- In addition to its protective qualities, R996 also helps improve the overall appearance of paints
- TR 28 titanium dioxide is also known for its stability and resistance to weathering, making it a reliable choice for products that are exposed to harsh environmental conditions. Whether used in outdoor paints or plastic products, TR 28 titanium dioxide helps maintain the product's appearance and performance over time.
- Another key advantage of titanium dioxide is its chemical stability. It is not affected by most acids, bases, or solvents, which makes it suitable for use in a variety of environments. This stability also means that titanium dioxide can be used in products that require long-term durability, such as outdoor paint and coatings.
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.
Though the regulated use of titanium dioxide in food products is legal in the U.S. and Canada, it's banned in some other countries, notably throughout Europe. In May 2021, the European Food Safety Authority announced that titanium dioxide can no longer be considered safe as a food additive.
Overall, the Food Directorate's comprehensive review of the available science of TiO2 as a food additive showed:
- Are your suppliers aware of this ban? Are they sourcing alternatives to comply with the legislative requirements?
- The wholesale availability of titanium dioxide anatase TIO2 plays a pivotal role in driving down costs for manufacturers without compromising on quality. By purchasing this key ingredient in bulk, paint manufacturers can take advantage of economies of scale, thereby reducing raw material expenses significantly. This cost-effective approach allows them to produce paints at a lower price point, making them accessible to a broader market segment.
