The brands of lithopone of the normal class, that of chemical manufacture, are marketed under such names as Ponolith, Beckton White, Jersey Lily White, Oleum White, Zinc Sulphide White, all of these being of domestic manufacture, and their composition is of the 30 per cent. zinc sulphide type. The German manufacturers and exporters of lithopone make use of fancy names for their brands and here are a few examples of these and the composition of the pigment:-
TiO2 comes in many different forms. However, only a few of these forms are considered food-grade (acceptable to be added to food). Many studies that raised concern about the safety of TiO2, including the concern for genotoxicity, used forms of TiO2 that are not considered acceptable for use in food and have different properties than food-grade TiO2. Other studies did use food-grade TiO2, but took steps to break the material down into smaller particles than what would normally be found in food.
- In the realm of industrial processing and manufacturing, the term 1250 mesh holds a significant position, particularly for those involved in powder and particle separation. This specification refers to a sieve size that is an essential component in various industries, from pharmaceuticals to mining and chemicals. The 1250 mesh manufacturers are the architects behind this intricate process, crafting equipment that ensures precision and efficiency in material separation.

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.
Research supports that applying titanium dioxide to the skin in the form of sunscreens, makeup, and other topical products does not pose any health risks.
- One of the primary uses of titanium dioxide is in the production of paints and coatings. It imparts a brilliant white color to these products, making them ideal for use on walls, ceilings, and other surfaces. The chemical properties of titanium dioxide also make it resistant to UV light and weathering, ensuring that painted surfaces remain vibrant and long-lasting.
2. Lithopone is widely used in the plastic industry.
It adds a bright white color to coffee creamers, baked goods, chewing gums, hard-shell candies, puddings, frostings, dressings, and sauces. But the nanoparticles found in “food-grade” titanium dioxide may accumulate in the body and cause DNA damage—which is one way chemicals cause cancer and other health problems.
Most notably, a European Food Safety Authority safety assessment published in May 2021 pointed to genotoxicity concerns, as suggested by previous research. Genotoxicity is the ability of chemicals to damage genetic information such as DNA, which may lead to cancer.
Research supports that applying titanium dioxide to the skin in the form of sunscreens, makeup, and other topical products does not pose any health risks.
The FDA has not updated its general guidance on safety assessments since 2007. Within that time, there has been a significant increase in research on the confluence of toxicology, nanotechnology and human health. The EU updates its guidance regularly with new science available to offer proper safety assessments, with its most recent update published in 2021.

Although most studies to date show no harmful effects of titanium dioxide consumption, few long-term human studies are available. Therefore, more research is needed to better understand its role in human health (16Trusted Source, 18Trusted Source).
