Titanium dioxide is a white food coloring agent often used in bakery decorations, soups, broths, sauces, spreads, creamers, candy, and chewing gum.
Health advocates urge US regulators to ban common food coloring additive, by Tom Perkins, The Guardian, June 2, 2023
Scrap zinc or concentrated zinc ores are dissolved in sulfuric acid, the solution is purified and the two solutions are reacted. A heavy mixed precipitate results that is 28 to 30% zinc sulfide and 72 to 70% barium sulfate.
For that reason, the Center for Science in the Public Interest has graded titanium dioxide as a food additive that consumers should seek to “avoid.” Scientists at the nonprofit nutrition and food safety watchdog group today published a new entry for titanium dioxide in its Chemical Cuisine database of food additives.
In conclusion, titanium dioxide is a game changer for the coatings industry. With its excellent hiding power, UV resistance, durability and environmental friendliness, it adds significant value to paint formulations. Whether you're looking to renovate your walls or looking for a solid paint option for your exterior surfaces, titanium dioxide-infused paints are the answer. Embrace the brilliance and durability that titanium dioxide has to offer and enjoy the long-lasting and vibrant finish it brings to your living spaces.
The CaCO3 and TiO2 factory not only provides a reliable supply of these materials to industries but also contributes to the local economy by creating job opportunities and generating revenue. The factory employs skilled workers in various departments such as production, quality control, and maintenance. It also collaborates with suppliers and distributors to ensure efficient transportation and delivery of CaCO3 and TiO2 to customers worldwide.
The integrity of surface skin cells was evaluated with and without solar simulated irradiation. The integrity of the stratum corneum was significantly lower in individuals treated with P25TiO2NPs under the light in comparison to the ones that received the functionalized nanoparticles. Cell membrane suffering is evident (Fig. 9), and it is in accordance with the ROS levels and macromolecule oxidation found in vitro for the irradiated P25TiO2NPs. Disruption of the superficial skin layer was observed in all animals treated with no functionalized nanoparticles, under irradiation. This data expands the findings by the group of Professors Fubini and Fenoglio, who showed that P25TiO2NPs could impact the lipid structure at the top few microns of the stratum corneum [55]. Control skin under irradiation and without any topic formulation did not show changes in cell structure.
Others focus on producing coated calcium carbonate, where the particles are coated with stearic acid or other substances to enhance dispersion and performance in applications like adhesives and sealants Others focus on producing coated calcium carbonate, where the particles are coated with stearic acid or other substances to enhance dispersion and performance in applications like adhesives and sealantsclassification of calcium carbonate factory.Earlier this year, a bill was introduced in the California legislature to ban the manufacture, sale and distribution of foods in the state containing titanium dioxide, along with four other harmful food chemicals.
In a statement sent to USA TODAY on Sunday, Justin Comes, vice president of research and development for Skittles maker Mars Wrigley North America, said the company couldn't comment on pending litigation – but that its use of titanium dioxide and all Mars Wrigley ingredients are safe and manufactured in compliance with strict quality and safety requirements established by food safety regulators, including the FDA.

Price increases of 139-174 USD /MT were seen in Q3 by western suppliers in a tight and buoyant market that faced multiple persistent pulls on supply, including an ongoing lack of Chinese export competitiveness. Furthermore, container constraints hampered its delivery to the rest of the world.
Following the EU’s ban on E171, the FDA told the Guardian that, based on current evidence, titanium dioxide as a food additive is safe. “The available safety studies do not demonstrate safety concerns connected to the use of titanium dioxide as a color additive.”
Titanium dioxide is produced at pigment grade or nano grade.
When evaluating suppliers, several factors come into play
Porcelain White, 32 per cent sulphide, 68 per cent barium sulphate.
The produced barium sulfide enters the leacher, and the temperature is controlled above 65°C to obtain a barium sulfide content of 70%, and then enters the clarification barrel, add zinc sulfate for reaction after clarification, control the zinc sulfate content to be greater than 28%, pH=8~9, and obtain a mixture of barium sulfate and zinc sulfide with a density of 1.296~1.357 g/cm3.
If you want to avoid titanium dioxide, Stoiber and Faber urge consumers to try and avoid processed foods as best as you can.
1. 296 to 1.357 g/cm3 is obtained. The reaction solution is subjected to pressure filtration through a plate frame to obtain a cake-like lithopone powder having a water content of not more than 45%. The mixture is calcined in a dry roaster to change the crystal form of the lithopone, and then acid-washed with sulfuric acid at a temperature of 80 °C. Finally, it is washed with water, reinforced with coloring agent, pressure filtration, drying and milling.
