  • Although the evidence for general toxic effects was not conclusive, on the basis of the new data and strengthened methods we could not rule out a concern for genotoxicity and consequently we could not establish a safe level for daily intake of the food additive, commented Matthew Wright, member of the EFSA's Food Additives and Flavourings Panel in a press statement.

  • 2. Cosmetics With its UV-filtering properties, anatase TiO2 is a popular ingredient in sunscreens and cosmetic formulations. Its ability to scatter UV radiation effectively protects the skin from harmful sun exposure, contributing to the increasing popularity of natural and mineral makeup products.


  • TiO2 is also used in the production of plastics, where it serves as a whitening agent and UV stabilizer. By incorporating TiO2 into plastic products, manufacturers can enhance their appearance, increase their lifespan, and improve their resistance to sunlight and weathering. Additionally, TiO2 helps prevent the degradation of plastic materials, ensuring that they retain their properties and performance over time.

  • In the wholesale market, titanium dioxide is available in various forms, including anatase, rutile, and brookite. Each form offers distinct advantages depending on the specific application requirements. For instance, anatase titanium dioxide is known for its high photocatalytic activity, making it an ideal choice for environmental applications such as air purification and water treatment. Rutile, on the other hand, is characterized by its high refractive index and excellent weathering resistance, making it a preferred choice for automotive coatings and plastic additives.
  • But what is titanium dioxide, exactly? Here's what you need to know about this popular food additive — including what products it's used in and whether it's safe to consume.

  • Titanium dioxide (TiO2) is the white pigment used to give whiteness and hiding power, also called opacity, to coatings, inks, and plastics. The reason for this is two-fold:

  • In a 2019 study published in the journal Nanotoxicology, researchers recreated the first phase of digestion in mice and fed them titanium dioxide, then examined whether accumulation occurred in the organs. Researchers wrote: “Significant accumulation of titanium was observed in the liver and intestine of E171-fed mice; in the latter a threefold increase in the number of TiO2 particles was also measured. Titanium accumulation in the liver was associated with necroinflammatory foci containing tissue monocytes/macrophages. Three days after the last dose, increased superoxide production and inflammation were observed in the stomach and intestine. Overall, [this] indicates that the risk for human health associated with dietary exposure to E171 needs to be carefully considered.”

  • The leaching reaction equation is: ZnO +n NH 3 · H 2 0→ [Zn NH 3 ) n] 2+ +20H—
  • To address these concerns, regulatory agencies around the world have established guidelines for the use of TiO2 in cosmetics. For example, the European Union has set limits on the amount of TiO2 allowed in cosmetic products, and the United States Food and Drug Administration (FDA) requires manufacturers to list TiO2 as an ingredient on product labels.
  • History of Lithopone Factories in China
  • Firstly, it is important to understand that TiO2 can be classified into two main types rutile and anatase. Rutile TiO2 is known for its excellent UV resistance, making it ideal for use in sunscreens, paints, and coatings. On the other hand, anatase TiO2 has a higher surface area and is often used in photocatalytic applications, such as self-cleaning coatings and air purification systems.
