Furthermore, we understand the importance of competitive pricing in today's market. That is why we work hard to offer our customers the best possible prices on Lithopone B311. By leveraging our relationships with manufacturers and optimizing our supply chain, we are able to pass on cost savings to our customers. This allows them to stay competitive in their respective industries while still benefiting from the quality of our products.

Lithopone B301, Lithopone B311 powder, brilliant white pigment used in paints, inks, leather, paper, linoleum, and face powder. It was developed in the 1870s as a substitute or supplement for lead carbonate (white lead), to overcome its drawbacks of toxicity, poor weathering, and darkening in atmospheres that contain sulfur compounds. Lithopone B301, Lithopone B311 powder is an insoluble mixture of barium sulfate and zinc sulfide that precipitates upon mixing solutions of barium sulfide and zinc sulfate. The precipitate is recovered by filtration, then calcined (roasted) at temperatures above 600° C (1,112° F). Although Lithopone B301, Lithopone B311 powder has been replaced in many applications by titanium dioxide, it is still widely used in a number of products, such as water paints.

Nanotoxicology 

Titanium dioxide (E 171) is authorised as a food additive in the EU according to Annex II of Regulation (EC) No 1333/2008.

High-purity anatase TiO2 from China, specifically the 99.6% variety, is a versatile and reliable product with numerous applications across various industries. Its exceptional physical and chemical properties, combined with strict quality control measures, make it a popular choice among manufacturers and consumers alike. As demand for this material continues to grow, Chinese suppliers will remain at the forefront of meeting the global demand for high-quality anatase TiO2.

CSPI says it might reconsider its rating if specifications for food-grade titanium dioxide in the U.S. are updated to ensure nanoparticles are minimized, and new studies are conducted to assess its capacity to cause cancer or other health problems. 

Micronized titanium dioxide doesn’t penetrate skin so there’s no need to be concerned about it getting into your body. Even when titanium dioxide nanoparticles are used, the molecular size of the substance used to coat the nanoparticles is large enough to prevent them from penetrating beyond the uppermost layers of skin. This means you’re getting the sun protection titanium dioxide provides with no risk of it causing harm to skin or your body. The coating process improves application, enhances sun protection, and prevents the titanium dioxide from interacting with other ingredients in the presence of sunlight, thus enhancing its stability. It not only makes this ingredient much more pleasant to use for sunscreen, but also improves efficacy and eliminates safety concerns. Common examples of ingredients used to coat titanium dioxide are alumina, dimethicone, silica, and trimethoxy capryl silane.

Titanium Dioxide Food Grade Suppliers Ensuring Safety and Quality In addition to its mechanical benefits, titanium dioxide also exhibits photocatalytic properties

Relative to a lot of other things that people should be concerned about, titanium dioxide in my mind, is really low on the list. I would be more worried about some substitutes that people are using for titanium dioxide that don't have decades of research associated with it, said Westerhoff.

Another prominent player is Tronox, which boasts a comprehensive portfolio of titanium dioxide pigments suitable for a variety of industries. With facilities around the globe, Tronox ensures reliable supply chains and meets the demands of customers worldwide. One of the key players in the Chinese titanium dioxide industry is the China Titanium Dioxide Plant. This state-of-the-art facility is equipped with the latest technology and machinery to produce high-quality titanium dioxide products. The plant is strategically located in a region with abundant titanium resources, allowing for cost-effective production and efficient supply chain management.

In a study published in the journal Environmental Toxicology and Pharmacology in 2020, researchers examined the effects of food additives titanium dioxide and silica on the intestinal tract by grouping and feeding mice three different food-grade particles — micro-TiO2, nano-TiO2, and nano-SiO2.  With all three groups, researchers observed changes in the gut microbiota, particularly mucus-associated bacteria. Furthermore, all three groups experienced inflammatory damage to the intestine, but the nano-TiO2 displayed the most pronounced changes. The researchers wrote: “Our results suggest that the toxic effects on the intestine were due to reduced intestinal mucus barrier function and an increase in metabolite lipopolysaccharides which activated the expression of inflammatory factors downstream. In mice exposed to nano-TiO2, the intestinal PKC/TLR4/NF-κB signaling pathway was activated. These findings will raise awareness of toxicities associated with the use of food-grade TiO2 and SiO2.”
