On November 23, 2022, the General Court of the European Union reversed the conclusion that titanium dioxide was carcinogenic and released a statement (1,2):
“First, the Commission made a manifest error in its assessment of the reliability and acceptability of the study on which the classification was based and, second, it infringed the criterion according to which that classification can relate only to a substance that has the intrinsic property to cause cancer.”
As part of our mission at CRIS we base our safety assessments on the currently available scientific evidence and consider many variables (e.g., study quality, journal of publication, etc.), even if it goes against previous conclusions. Evidence-informed decisions making is critical to ensure that the laws and regulations put into place are for the benefit of the population.
The EU General Court maintains that the scientific evidence presented wasn’t the complete picture for the ingredient, “in the present case, the requirement to base the classification of a carcinogenic substance on reliable and acceptable studies was not satisfied.”
Due to its light-scattering properties, small amounts of titanium dioxide are added to certain foods to enhance their white color or opacity (1Trusted Source, 3Trusted Source).
3. Lithopone can be used as a filler for leather and linoleum.
Recent analyses of food-grade TiO2 samples have found that a significant portion of particles may be within the nanoscale. These particles (also known as nanoparticles) range in size from 1 to 100 nm, where 1 nm equals 1 billionth of a metre (the width of a typical human hair is 80,000 to 100,000 nm).
Overall, TiO2 powder suppliers play a vital role in ensuring that industries have access to the high-quality TiO2 powder they need for their various applications. By sourcing and supplying this essential raw material, TiO2 powder suppliers help to drive innovation and growth in industries around the world.
Anyway, it doesn't matter if it reflects or absorbs, Titanium Dioxide is a pretty awesome sunscreen agent for two main reasons: it gives a nice broad spectrum coverage and it's highly stable. Its protection is very good between 290 - 350 nm (UVB and UVA II range), and less good at 350-400 nm (UVA I) range. Regular sized Titanium Dioxide also has a great safety profile, it's non-irritating and is pretty much free from any health concerns (like estrogenic effect worries with some chemical filters).
Evonik, for instance, offers a range of micro TiO2 grades under the brand name Tioxide, catering to the demands of various industries. Cristal Global, with its extensive global presence, supplies micro TiO2 for applications in coatings, plastics, and more. Tronox, another major player, provides innovative solutions through their TioXide product line. Venator Materials, with its legacy in mineral processing, ensures reliable supply and technical support.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.

Mesh, in the context of sieving, denotes the number of openings in a linear inch of a screen or sieve. A 1250 mesh sieve indicates an incredibly fine mesh size, where particles pass through a sieve with approximately 1250 openings per square inch. This level of fineness is crucial for applications requiring minute particle separation, such as in the production of high-quality powders or ultra-refined materials.Lithopone 30% CAS No. 1345-05-7 / Application
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.
However, there are still some challenges associated with ensuring the safety of TiO2 in food manufacturing. One of the main challenges is the lack of standardized testing methods for TiO2. This makes it difficult to accurately determine the levels of TiO2 in food products and to identify potential health risks.Quality control is another cornerstone of the factory’s operations. Advanced analytical instruments monitor every aspect of production, ensuring that the titanium dioxide pigments meet stringent international standards for color consistency, opacity, and durability. As a result, the factory's products are highly sought after, securing their place in both domestic and international markets. As the demand for titanium dioxide continues to rise, the China Titanium Dioxide Plant is poised to expand its production capacity and further strengthen its position in the market. By investing in cutting-edge technology, fostering innovation, and maintaining a commitment to sustainability, the plant is well-equipped to meet the challenges of the future and continue to drive growth in the Chinese titanium dioxide industry.
