Titanium dioxide mainly comes from the earth’s crust, where it’s actually the ninth most common element. When processed, it becomes a fine powder with a vibrant white pigment.

The main food categories contributing to dietary exposure of E171 are fine bakery wares, soups, broths and sauces (for infants, toddlers and adolescents); and soups, broths, sauces, salads and savoury based sandwich spreads (for children, adults and the elderly). Processed nuts are also a main contributing food category for adults and the elderly.
TiO2 powder is also widely used in the cosmetics industry, where it is used as a whitening agent in skincare products, sunscreen, and makeup. TiO2 powder suppliers work closely with cosmetic manufacturers to ensure that they have a reliable and high-quality supply of TiO2 powder to meet the demands of their consumers.
There is some concern regarding skin and intestinal absorption of titanium dioxide nanoparticles, which are less than 100 nm in diameter.
In conclusion, anatase titanium dioxide producers are vital players in the modern industrial landscape. Their expertise in manufacturing a material with exceptional properties ensures that industries ranging from construction to electronics can harness its potential. As we look towards a future where sustainable practices and technological breakthroughs are paramount, these producers will undoubtedly continue to be at the forefront of innovation and progress. Lithopone B301 is highly valued for its excellent hiding power and brightness, making it an ideal choice for high-quality paints and coatings. Its particle size distribution ensures seamless integration into different mediums, enhancing the overall performance of the end product. On the other hand, Lithopone B311 distinguishes itself with increased chemical stability and resistance to fading, attributes that are crucial for applications requiring longevity and exposure to harsh environments.
Additionally, the committee noted that the available data did not provide convincing evidence of genotoxicity for titanium dioxide as a food additive, but recognized the limitations in current methodologies with respect to the testing of poorly soluble particulate materials. Although there were uncertainties in the genotoxicity data, the experts took into account the fact that the additive was not carcinogenic in adequately conducted two-year studies in mice and rats at doses of up to 7,500 mg/kg BW per day for mice, and 2,500 mg/kg BW per day for rats, the highest doses tested. There was also no evidence of reproductive or developmental toxicity in studies in rats at doses up to 1,000 mg/kg BW per day, the highest doses tested.
Lithopone, a white pigment composed of a mixture of barium sulfate and zinc sulfide, is commonly used in the leather industry as a coloring agent. Leather suppliers around the world rely on lithopone to achieve the desired color and finish on their products.
Although barium sulfate is almost completely inert, zinc sulfide degrades upon exposure to UV light, leading to darkening of the pigment. The severity of this UV reaction is dependent on a combination of two factors; how much zinc sulfide makes up the pigments formulation, and its total accumulated UV exposure. Depending on these factors the pigment itself can vary in shade over time, ranging from pure white all the way to grey or even black. To suppress this effect, a dopant may be used, such as a small amount of cobalt salts, which would be added to the formulation. This process creates cobalt-doped zinc sulfide. The cobalt salts help to stabilize zinc sulfide so it will not have as severe a reaction to UV exposure.
History of Lithopone Factories in China② Plastics: At present, it is the second largest user of titanium dioxide pigments, accounting for about 20% of the total demand for titanium dioxide. The amount of titanium dioxide used in plastic products will vary with the use requirements, generally between 0.5% and 5%. According to data from the National Bureau of Statistics, the production of plastic products in China increased from 57.81 million tons in 2012 to 81.84 million tons in 2019, with a compound annual growth rate of 5.1%. The amount of titanium dioxide increases accordingly.
