  • Other research suggests that E171 could cause harm; however, those research processes did not consider how people are typically exposed to E171. Research that adds E171 to drinking water, utilizes direct injections, or gives research animals E171 through a feeding apparatus is not replicating typical human exposure.

  • Moreover, lithopone's influence on processing cannot be overlooked. It facilitates easier mixing and molding by acting as a lubricant during the compounding stage. This results in reduced energy consumption and shorter cycle times, translating into increased efficiency and lower production costs for manufacturers.
  • Apart from its use in pigments and additives, titanium dioxide is also employed in the production of other chemicals

  • Animal studies have shown that, when consumed as a food additive, titanium dioxide can induce intestinal inflammation.

  • Barium sulphate is typically described as a white, odorless powder. This white coloration is due to its crystalline structure and the arrangement of Ba^2+ and SO₄^2− ions within the compound. The brightness and consistency of this white powder are crucial for its use in various applications. For instance, in the pharmaceutical industry, barium sulphate is used as a radiopaque agent in X-ray imaging of the gastrointestinal tract. In this context, its purity and the absence of color impurities are vital for ensuring accurate imaging results.


  • This regulation entered into force on 7 February 2022. However, the Regulation included a six-month transitional period to allow food businesses time to phase out the use of this food additive and to reformulate their products using suitable alternatives. This period will end on 7 August 2022.

  • The conjugation of vitamin C to the P25TiO2NPs was confirmed by UV-visible spectroscopy of lyophilized vitaminC@P25TiO2NPs suspensions. The typical absorbance peak of ascorbic acid at 265 nm was found. However, no further characterization was done because they did not show the expected protective effect against the photo-induced cell damage (Fig. 3).

  • In order to evaluate the penetration of the nanoparticles, eight adult male Wistar rats (3 months old) were used for the in vivo experiments. The protocol was approved by the local University Committee for animal testing and is in accordance with the Canadian Council on Animal Care (CICUAL-RD-2021–892-E-UNC-DEC#FCQ).

  • In food products, E171 is not a singular ingredient; it’s always combined with other ingredients (e.g., proteins and fats) in the food product. Digesting food is a slow process for the body compared to drinking a beverage, which passes much faster through the body. 

  • Sustainability concerns are at the forefront of industrial developments, and TIO2 aligns seamlessly with green initiatives. Though traditionally produced through mining, advancements in synthetic production have mitigated environmental impacts. Furthermore, the photocatalytic nature of TIO2 allows it to interact with sunlight and facilitate the breakdown of organic pollutants on painted surfaces, contributing to cleaner environments.

  • In conclusion, the precipitation of titanium dioxide is a crucial step in the production of this widely used white pigment. Understanding the various methods and factors that influence this process is essential for optimizing production efficiency and product quality. With ongoing research and development, it is expected that new and improved precipitation techniques will emerge in the future, further enhancing the sustainability and competitiveness of TiO2 production.
  • Titanium dioxide is widely used in industries ranging from paints and cosmetics to food colorants and solar cells. Its purity is of utmost importance, and the presence of impurities like sulfate can significantly affect its performance and safety. The conversion of sulfate into TiO2 during the manufacturing process requires stringent control and accurate measurement to ensure product quality and compliance with regulatory standards.
  • In conclusion, rutile titanium dioxide variants such as DHR-966, SR-2377, R5566, R218, R996, and THR-6666 play a crucial role in various industries due to their unique properties and performance benefits. Whether you are looking for high opacity, excellent dispersion, cost-effectiveness, durability, or thermal stability, there is a rutile titanium dioxide option to meet your specific needs.
  • Ceramics and Tiles: Lithopone powder is utilized in the ceramics industry to improve the brightness and opacity of ceramic glazes, tiles, and sanitaryware. It helps achieve uniform coloration and surface finish, enhancing the aesthetic appeal of ceramic products.

  • Titanium dioxide holds exceptional significance as a white pigment due to its superior scattering capabilities, remarkable chemical stability, and non-toxic nature. Among all white pigments, it surpasses others in terms of its ability to scatter light effectively. Consequently, titanium dioxide stands as the most significant inorganic pigment, accounting for the highest quantity in usage. The majority part of the global production of ilmenite and rutile is dedicated to the production of TiO2 pigments. The remaining portion is utilized for the manufacturing of titanium metal and in the production of welding electrodes.

  • There’s also concern that exposure to the mineral over time, even in small amounts, can build up in the body, particularly in the kidneys, spleen and liver. Although most of the mineral is excreted in feces, there is evidence that a small percentage may remain in bodily organs.

  • In recent years, China's production of talc and titanium dioxide has increased significantly, making it one of the world's largest producers of these minerals. According to the US Geological Survey, China produced approximately 2.5 million metric tons of talc and 2.4 million metric tons of titanium dioxide in 2019 alone. This growth can be attributed to the country's vast reserves of these minerals, as well as government initiatives aimed at boosting domestic production and reducing reliance on imports.

  • Procurement of TIO2 involves a complex process, starting from sourcing the raw materials, primarily ilmenite, rutile, or titanium-bearing slag, to negotiating contracts with suppliers. Manufacturers often prioritize suppliers that can guarantee consistent quality, competitive pricing, and reliable delivery schedules. This necessitates strong relationships and strategic partnerships with mining companies, which are typically located in regions rich in titanium resources, such as Australia, South Africa, and Canada.

  • However, most dermatologists will warn their patients not to rely on mineral makeup alone in order to be protected by the sun’s rays. This is because there can be quite a bit of variation with mineral foundation – not only with how much we apply but how much titanium dioxide the foundation contains.
