  • 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).

  • Volatile elements 105℃

  • Overwhelmingly, research that’s relevant to human eating patterns shows us that E171 is safe when ingested normally through foods and drugs (1,2).

  • Studies suggest that people are more likely to buy and eat foods that are brighter or more vibrant in color. And titanium dioxide is one way to make that happen. You can find it in food products like candy, coffee creamer, baking and cake decorations, and white sauces.

  • The construction industry, for instance, has long utilized cheap barium sulfate superfine as a filler in cement and concrete mixtures. Its high density contributes to increased weight and stability, while its inertness ensures minimal chemical reactions, enhancing the durability of structures. Moreover, in the oil and gas sector, it serves as a weighting agent in drilling fluids, preventing blowouts by adding density to the fluid and stabilizing wellbores.

  • TiO2 NPs appeared to be more toxic to nematode Caenorhabditis elegans than submicron-sized TiO2.  At a concentration of 1 mg/l, 7 nm particles affected its fertility and survival rate and were more toxic than 20 nm anatase particles. Similarly, Hu et al. showed that rutile particles (10–20 nm), at concentrations above 1 g/kg soil, can be bio-accumulated in earthworms, where they induce oxidative stress, inhibit the activity of cellulase and induce DNA and mitochondrial damage.

  • Production Process
  • It has an extremely high melting point of 1 843ºC and boiling point of 2 972ºC, so occurs naturally as a solid, and, even in its particle form, it is insoluble in water. TiO2 is also an insulator.

  • The whole scientific experimental design in some of these studies is‌ very flawed, Kaminski said.

  • The FDA is reviewing the safety of titanium dioxide in response to an April petition from EWG and other environmental and public health groups. This is the FDA’s first comprehensive review of titanium dioxide since 1973.

  • It is imperative to engage with suppliers that prioritize research and development. The field of conductive materials is rapidly evolving, and partnerships with innovative suppliers can provide access to cutting-edge advancements, enhancing the competitiveness of your own products or research outcomes. Collaboration opportunities such as joint development projects or access to technical expertise can foster an environment where both parties benefit from shared knowledge and resources.

  • The paper industry also benefits from the use of titanium dioxide, as it enhances the brightness and opacity of paper productstitanium dioxide application range manufacturer. Manufacturers add TiO2 to achieve a consistent white shade, which is essential for printing and writing purposes. Moreover, titanium dioxide helps improve the strength and smoothness of paper, resulting in higher quality products for consumers.
  • Characteristics of Common White Pigments

  • Check food product labels and avoid those with titanium dioxide. Food companies must list titanium dioxide on packaged food ingredient labels. In some instances, it may simply be listed as “artificial color” or “color added.”
  • Sulphate process. The ilmenite is reacted with sulphuric acid giving titanium sulphate and ferric oxide. After separation of ferric oxide, addition of alkali allows precipitation of hydrous titanium dioxide. The washed precipitate is calcined in a rotary kiln to render titanium dioxide. The nucleation and calcination conditions determine the crystalline structure of titanium dioxide (e.g. rutile or anatase).

  • As the demand for natural and safe cosmetic products continues to grow, the use of TiO2 in cosmetics is likely to increase. However, manufacturers will need to continue to address safety concerns and comply with regulatory requirements to ensure the safe use of TiO2 in cosmetic products.
