- Moreover, chemical pigment manufacturers need to work closely with their clients to understand their specific needs and requirements. Whether it's designing custom colors or developing pigments with specific properties, such as UV resistance or heat stability, manufacturers need to be flexible and responsive to the demands of their customers. This requires strong communication skills and a deep understanding of the market trends and consumer preferences.

- UV Resistance: Its resistance to UV radiation makes lithopone powder suitable for outdoor applications, where durability and color stability are paramount.
-
The reaction liquid is filtered through plate and frame pressure to obtain lithopone in the form of a filter cake with a moisture content of no more than 45%. It is then roasted in a drying furnace to change the crystal form of lithopone, and is then pickled with sulfuric acid at a temperature of 80°C. Finally, it is washed with water, reinforced with colorants, filtered, dried and ground into powder.

Often used as a glaze for ceramics, titanium dioxide provides a bright, glossy finish and improves the durability and stain resistance of ceramic products.

Currently, titanium dioxide as a food additive is classified as GRAS, or “generally recognized as safe.”

Importantly, TiO2 also has a very high refractive index (its ability to scatter light), even higher than diamond. This makes it an incredibly bright substance and an ideal material for aesthetic design use.

if you compare the levels—which went as high as 50,000 milligrams/killigrams per day— to what humans are actually exposed to, we're talking orders of magnitude. It was a huge amount, Norbert Kaminski, PhD, a professor of pharmacology & toxicology and director of the Center for Research on Ingredient Safety at Michigan State University told Health.

- The pricing of lithopone pigment varies depending on numerous factors such as quality, purity, production capacity, and global market dynamics. High-quality lithopone, with a higher percentage of zinc sulfide, tends to command a premium price due to its superior performance characteristics. On the other hand, barium sulfate content influences the density and whiteness of the pigment, which can also affect the pricing.
The assessment was conducted following a rigorous methodology and taking into consideration many thousands of studies that have become available since EFSA’s previous assessment in 2016, including new scientific evidence and data on nanoparticles.

Because of their small size, nanoparticles may have unique physical and chemical properties. These properties may cause them to interact with living systems differently than larger materials with the same chemical composition (also known as bulk materials).
lithopone supplier 30% applied in masterbatch has maximum purity, good opacity and reasonable light fastness.
Historical references
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.

Specification
Thanks to its rheological and optical properties, Lithopone offers both technical and economic advantages wherever organic and inorganic binder systems require a relatively high pigmentation for specific applications.
Having thus described the origin and uses of the pigment, we now come to the question, what is lithopone? It is, in short, a chemical compound usually consisting of 30.5 per cent zinc sulphide, 1.5 per cent zinc oxide and 68 per cent barium sulphate, but these proportions vary slightly in the different makes. Lithopone of this composition is sold as the highest grade, either as red seal or green seal, as it best suits the idea of the manufacturer. Many manufacturers, especially in Europe, sell and also export other brands under other seals, containing 24, 20, 18 and as little as 12 per cent of zinc sulphide with very small percentages of zinc oxide, the balance being usually barium sulphate, but sometimes certain portions of China clay or gypsum (calcium sulphate) or whiting (calcium carbonate). Such brands are not a chemical compound, but mechanical mixtures of the chemically compounded lithopone and the admixtures referred to.
To avoid exposure to titanium dioxide, follow these recommendations:
Lithopone 30% has a lower coverage power than titanium dioxide. For this reason, Lithopone 30% can only partially substitute titanium dioxide, between 5 and 40%.
