States looking to ban titanium dioxide as a food additive
- When it comes to sourcing TiO2, there are several key factors that potential buyers must consider. The first is quality; high-grade TiO2 is essential for applications requiring superior brightness and durability. Quality is determined by the purity of the titanium dioxide and the uniformity of its particle size distribution.
- Innovative automation and digitalization technologies are also transforming the white titanium dioxide industry. Smart factories equipped with IoT devices, sensors, and AI algorithms optimize production processes, enhance quality control, and ensure consistent product quality. These advancements not only boost productivity but also create safer working environments for employees.
- Spectrophotometric methods are also employed, where the absorbance of light by a sample is measured after a color-forming reaction specific to sulfate. By comparing the absorbance values to a calibration curve prepared with standards of known TiO2 content, the concentration of sulfate can be accurately determined.
- Despite these positive developments, challenges remain for TiO2 factories. One major issue is the depletion of high-grade ilmenite ore, which is the primary source of titanium for producing TiO2. This has led some factories to explore alternative sources of titanium, such as upgrading lower-grade ores or。,,TiO2,。
Wegman’s puts titanium dioxide in its Original Macaroni and Cheese. Campbell’s Healthy Request Chunky Chicken Corn Chowder has it, as does Food Club’s Chunky New England Clam Chowder. Marzetti uses the color agent to brighten its Cream Cheese Fruit Dip. Dairy products usually don’t need titanium dioxide to look white, but Kroger has decided to add titanium dioxide to its Fat Free Half-and-Half. And titanium dioxide isn’t only in especially white or brightly colored foods: Little Debbie adds it to Fudge Rounds and many other products. According to the Food Scores database maintained by Environmental Working Group, more than 1,800 brand-name food products have titanium dioxide on their ingredients list. That said, it can still lurk as an unspecified “artificial color,” or labels might simply say “color added.”

- Lithopone, a versatile white pigment, has been a staple in the world of colorants for decades due to its excellent opacity, stability, and cost-effectiveness. It is a mixture of zinc sulfide and barium sulfate, providing a superior white shade in various applications, including paints, plastics, printing inks, and coatings. This article delves into the lithopone pigment price list and highlights key suppliers in the market.
- The production process at a TiO2 concrete factory begins with the careful sourcing of high-quality raw materials. Titanium dioxide is extracted from mineral sources like rutile and ilmenite through a complex series of chemical reactions. Simultaneously, other ingredients such as cement, aggregates, and water are prepared for the concrete mixture.

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.”

Results and discussion
Overall, the precipitation of titanium dioxide is a complex process that requires careful control of various factors to achieve the desired product properties. By optimizing the precipitation percentage and carefully monitoring the precipitation process, manufacturers can produce high-quality titanium dioxide that meets the stringent requirements of their customers in the paints, coatings, plastics, and cosmetics industries.
