  • Lithopone is rather nontoxic, due to the insolubility of its components. It has been used in medicine as a radiocontrast agent. Lithopone is allowed to be in contact with foodstuffs in the US and Europe.[1]

  • Whiteness is a critical factor in the performance of pigments, and TiO2 excels in this area. Its high refractive index allows it to scatter light more effectively, resulting in a brighter and more luminous color. This makes TiO2 particularly suitable for applications where maximum whiteness is required, such as in paints, plastics, and paper.
  • The profiles of key players and their key strategic developments are enlisted in the report.
  • In conclusion, TiO2 factories have come a long way since their inception, evolving from rudimentary production methods to sophisticated processes that prioritize both quality and environmental stewardship. As demand for titanium dioxide continues to grow, these facilities will undoubtedly play a vital role in shaping the future of this versatile compound while navigating the complex landscape of resource availability, technological innovation, and ecological responsibility.
  • The first step in obtaining titanium dioxide typically begins with the mining of ilmenite, rutile, and anatase – minerals that contain titanium. These minerals are extracted from the earth through open-pit or underground mining methods. Once mined, they undergo beneficiation processes such as crushing, grinding, and gravity separation to concentrate the titanium-bearing ore.

  • China has emerged as a significant player in the global talc and titanium dioxide market, contributing to the production, consumption, and export of these essential minerals. Talc, also known as talcum powder, is a naturally occurring mineral that is widely used in various industries, including papermaking, plastics, rubber, cosmetics, and pharmaceuticals. Titanium dioxide, on the other hand, is a white pigment that is primarily used in paints, coatings, plastics, and paper. Both minerals have unique properties that make them indispensable in numerous applications.

  • In recent years, China's production of talc and titanium dioxide has increased significantly, making it one of the world's largest producers of these minerals. According to the US Geological Survey, China produced approximately 2.5 million metric tons of talc and 2.4 million metric tons of titanium dioxide in 2019 alone. This growth can be attributed to the country's vast reserves of these minerals, as well as government initiatives aimed at boosting domestic production and reducing reliance on imports.

  • In a review published in 2022 in the journal Archives of Toxicology, researchers found that the ingestion of E171 is a “a definite health risk for consumers and their progeny.” After reviewing dozens of in vivo, ex vivo and in vitro studies on the toxicity of E171, the researchers wrote that two facts must be noted: “First, reprotoxicity studies show that animals of both sexes are impacted by the toxicity of these nanoparticles, underlining the importance of conducting in vivo studies using both male and female animals. Second, human exposure begins in utero via maternal-fetal transfer and continues after birth by breastfeeding. Children are then chronically re-exposed due to their food preferences. To be relevant to the human in vivo situation, experimental studies should therefore consider nanoparticle exposure with respect to the age or life period of the studied population.”

  • It is expected that the implementation of rutile titanium dioxide market manufacturers will be stable this week, the new single quotation of the production link will be firm, the supply of low-cost goods will be reduced, and the reference range of the overall market transaction will rise slightly. It is expected that the market transaction reference is 15200-16200 yuan/ton, and the weekly average price may refer to 15600 yuan/ton. In addition, considering the difference of orders received by different manufacturers, some manufacturers may still have 300-500 yuan/ton of negotiation room. On the demand side, most buyers still have inventory to use, so the current new batch transaction intention is not strong; On the supply side, some producers are expected to increase the load next week, so the industry time output may be slightly increased. On the whole, it is expected that the overall trading range will rise slightly next week, but most producers will adjust the real single negotiation range according to their own orders, and the new single stable price of mainstream producers.

  • 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.
