The US and Canada, however, approve the use of titanium dioxide as a food additive. Canada's recent review of titanium dioxide reconfirmed its safety and pointed out that many of the toxicity studies the EU reviewed were not relevant to the safety of titanium dioxide as a food ingredient, and that the ban is based on an abundance of caution and uncertainty.

- In conclusion, understanding the dynamics of lithopone prices and its suppliers is crucial for businesses that rely on this pigment. As the industry evolves, suppliers need to adapt to changing market conditions, environmental regulations, and consumer preferences to maintain their competitive edge. Meanwhile, buyers must stay informed about these changes to make strategic purchasing decisions that balance cost-effectiveness with product quality.
- In the pharmaceutical industry, micro TiO2 is used as an inactive ingredient, serving as a colorant, filler, or glidant in tablets and capsules. It's non-toxic nature and inertness make it safe for consumption.
- The commitment to excellence does not stop at production methods; it extends to the research and development of new lithopone formulations
Particle size: optimum particle size to produce maximum opacity is 200–300 nm.
The annual production capacity of high-grade rutile titanium dioxide has reached more than 400,000 tons. It is one of the largest TiO2 manufacturers in China at present. It has more than ten product brands of Taiohua, Jinxing and other brands, and its products are sold in more than 50 countries and regions around the world. It has long maintained the excellent performance of the second overall ranking in the domestic titanium dioxide industry.
Lithopone is an inorganic white pigment, obtained from co-precipitation of Zinc sulfide (ZnS) and Barium sulfate (BaSO4). Titanium Dioxide (TiO2) has replaced Lithopone as a white pigment in majority applications as TiO2 is more durable. However, it is much cheaper than TiO2 and has advantages such as low binder requirement and good dispensability. As a white pigment, it can improve the substrate's weather resistance, and improve the fungicidal properties of paint formulations. Some of the major applications of Lithopone include manufacturing of paint pigments, plastic & rubber products, paper, printing inks, cosmetics, and leather & linoleum products. It is commercially available under names such as pigment white 5, Barium zinc sulfate sulfide, Becton White, C.I. 77115, Charlton White, Enamel White, and Zincolith. On the basis of content of ZnS, Lithopone is available at 28%-30% Lithopone and 60% Lithopone.
