On November 23, 2022, the General Court of the European Union reversed the conclusion that titanium dioxide was carcinogenic and released a statement (1,2):
“First, the Commission made a manifest error in its assessment of the reliability and acceptability of the study on which the classification was based and, second, it infringed the criterion according to which that classification can relate only to a substance that has the intrinsic property to cause cancer.”
As part of our mission at CRIS we base our safety assessments on the currently available scientific evidence and consider many variables (e.g., study quality, journal of publication, etc.), even if it goes against previous conclusions. Evidence-informed decisions making is critical to ensure that the laws and regulations put into place are for the benefit of the population.
The EU General Court maintains that the scientific evidence presented wasn’t the complete picture for the ingredient, “in the present case, the requirement to base the classification of a carcinogenic substance on reliable and acceptable studies was not satisfied.” -
Lithopone was discovered in the 1870s by DuPont. It was manufactured by Krebs Pigments and Chemical Company and other companies.[2] The material came in different seals, which varied in the content of zinc sulfide. Gold seal and Bronze seals contain 40-50% zinc sulfide, offering more hiding power and strength.[3] Although its popularity peaked around 1920, approximately 223,352 tons were produced in 1990. It is mainly used in paints, putty, and in plastics.[1]
- Incorporating rutile TiO2 into latex paints requires meticulous attention to dispersion techniques

Color -
- TiO2 particles of the right size scatter visible light, having wavelength λ ≈ 380 - 700 nm, effectively because TiO2 has a high refractive index
- Photocatalytic activity is another fascinating property of rutile TiO2
- In addition to these traditional uses, titanium dioxide is gaining popularity in emerging fields such as photocatalysis and solar energy conversion

4. Emergency procedures The MSDS should outline steps to take in the event of an accident or exposure to lithopone, including first aid measures and contact information for emergency responders.
- Moreover, anatase titanium dioxide contributes to the durability and longevity of coatings. Its excellent weatherability ensures that coatings remain intact and retain their performance properties even in harsh environmental conditions
anatase titanium dioxide in coatings manufacturers. This is crucial for outdoor coatings, which are exposed to a wide range of external factors that can degrade their quality over time. - In the plastics industry, titanium dioxide is added to polymer resins to enhance their whiteness and brightness. This is particularly important for products that are exposed to sunlight or harsh environmental conditions, as the pigment helps to prevent yellowing and deterioration over time. TiO2 is also used in food packaging materials to create a white appearance that is appealing to consumers.
- The lithopone factory in China plays a crucial role in the global pigment industry, providing high-quality products at competitive prices. While the industry faces challenges, the government's efforts to promote sustainable development and the increasing demand for eco-friendly products offer opportunities for growth. As the industry continues to evolve, it will be important for factories to adopt environmentally friendly practices and innovate to remain competitive in the global market.

CSPI’s Chemical Cuisine is the web’s definitive rating of the chemicals used to preserve foods and affect their taste, texture, or appearance. Besides titanium dioxide, the group recommends avoiding artificial sweeteners like aspartame, acesulfame potassium, and sucralose, as well as synthetic food dyes like Yellow 5 and Red 3. CSPI and others have recently asked the Food and Drug Administration to ban the latter dye in foods and ingested drugs because the FDA has already determined that it is a carcinogen unsafe for use in cosmetics.

If you're curious about whether something you’re eating contains titanium dioxide, you can check the ingredients list. But know that the FDA doesn’t require food makers to use its chemical name on an ingredients list. Instead, it could be listed as:
-
Lithopone or sulphide of zinc white has been in general use for twenty years or more in many industries where a white pigment of considerable body or hiding power is required that is not subject to change like lead carbonate and has not the brittle character of zinc oxide, besides being sold at a lower figure than either of these. Nevertheless it is still comparatively new to the general painting trade. Because of our tariff protection its manufacture in this country has made great progress. Yet in spite of this and the duty imposed on it, the imports are still in excess of the quantity manufactured here. A short history of its origin will no doubt prove of interest to our readers.

Titanium dioxide is widely used as a color-enhancer in cosmetic and over-the-counter products like lipsticks, sunscreens, toothpaste, creams, and powders. It’s usually found as nano-titanium dioxide, which is much smaller than the food-grade version (7Trusted Source).

- Production Process of Lithopone
When manufacturers add titanium dioxide to foods and other ingestible products, it’s typically referred to as E171, which relates to food-grade purity.
One of the key advantages of using anatase titanium dioxide in coatings is its superior UV resistance. This makes it ideal for outdoor applications where coatings are exposed to sunlight and other environmental factors that can degrade the finish over time. Anatase titanium dioxide helps to protect the underlying surface from UV rays, preventing fading and deterioration.
- In the nitrile glove factory setting, the careful dispersion of titanium dioxide particles is crucial. Advanced manufacturing techniques ensure that TiO2 is evenly distributed throughout the nitrile compound, maximizing its benefits without compromising the gloves' thinness or dexterity.
Delivery Format - occasionally, through our blood and eyes.
- Overall, calcium carbonate and titanium dioxide are essential minerals in the global industrial market, with China playing a key role in their production and export. As demand for these minerals continues to grow, it will be important for China to invest in sustainable production practices and improve the efficiency of its mining and processing operations to meet global demand in a responsible manner.
- China's TiO2 manufacturers have been investing heavily in research and development to improve the quality and performance of their products. They have been focusing on developing innovative formulations and production processes to meet the diverse needs of the market.
