With a specially designed inorganic surface coating treatment, R-895 excels in weather resistance, making it flexible for use in various indoor and outdoor applications.
3. Lithopone can be used as a filler for leather and linoleum.
After conducting a review of all the relevant available scientific evidence, EFSA concluded that a concern for genotoxicity of TiO2 particles cannot be ruled out. Based on this concern, EFSA’s experts no longer consider titanium dioxide safe when used as a food additive. This means that an Acceptable Daily Intake (ADI ) cannot be established for E171.
It is a white crystalline powder, which is a mixture of zinc sulfide and barium sulfate. The more zinc sulfide it contains, the stronger the hiding power and the higher the quality. The density of lithopone is 4.136~4.34/cm3 and it is insoluble in water. It easily decomposes when exposed to acid to produce hydrogen sulfide gas, but does not work when exposed to hydrogen sulfide and alkaline solutions.

Background
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]
The production of barium sulfate involves several stages, including mining, beneficiation, and processing. The first step is to extract barium sulfate from the earth, which is typically done through underground or open-pit mining methods. Once the ore is extracted, it undergoes beneficiation to separate the barium sulfate from other impurities. This process may include washing, grinding, and flotation techniques. Today, pigment lithopone factories continue to operate globally, albeit on a smaller scale than during their peak in the mid-20th century. They have become more efficient and environmentally conscious, thanks to advancements in technology and increased regulation. Furthermore, they have diversified their product lines to include other pigments and compounds, ensuring their survival in an increasingly competitive market. Lastly, in the food industry, titanium dioxide is sometimes used as a food coloring agent. It can add a bright white color to powdered sugar, icing, and candy, enhancing their appearance without affecting the flavor. However, its use is strictly regulated to ensure consumer safety. In addition to paints and coatings, titanium dioxide powder is also widely used in the cosmetics and personal care industry. Titanium dioxide is a common ingredient in sunscreens, as it provides excellent UV protection and helps prevent sunburn and skin damage. Suppliers who can offer titanium dioxide powder that meets stringent regulatory requirements and quality standards are crucial for manufacturers of sunscreen products.
