On the other hand, the U.S. Food and Drug Administration (FDA) in their Final Administrative Order on Sunscreen Drug Products posted in September 2021 still accepts titanium dioxide up to 25% in the list of Generally Recognized As Safe and Effective (GRASE) in the main document, without further clarification on what kind or size of particles [9]. However, on page 24 (Sunscreen containing nanomaterials) FDA clearly “distinguish nanomaterials from other forms of these ingredients'' (zinc oxide and titanium dioxide) and ask for comments on “any particular nanomaterials that you believe should not be permitted for use in OTC sunscreen products”. To the best of our knowledge, this Agency did not ban the use of nanoparticulate titanium dioxide in any form, even though it is mentioned on page 34 that the anatase form is the more photoactive one, due to the lack of evidence with real sunscreens OTC (over the counter) in vivo. Moreover, other regulations in Latin America (MERCOSUR agreement, 2006) do not state clearly their position on the use of nanoparticulate TiO2NPs [10].

Yes. According to the FDA and other regulatory agencies globally, “titanium dioxide may be safely used for coloring foods”. Titanium dioxide is safe to use, and the FDA provides strict guidance on how much can be used in food. The amount of food-grade titanium dioxide that is used is extremely small; the FDA has set a limit of 1 percent titanium dioxide for food. There is currently no indication of a health risk at this level of exposure through the diet.

  • In conclusion, anatase titanium dioxide nanoparticles are emerging as factories for advanced applications due to their unique properties and vast potential. As research continues to advance, we can expect to see even more innovative uses for these fascinating nanoparticles in the future.
  • In the realm of industrial materials, few substances command as much versatility and demand as Titanium Dioxide (TiO2) powder, particularly in its rutile form. This white pigment is not only a cornerstone in the manufacturing of paints, plastics, paper, and sunscreens but also plays a crucial role in photocatalysts and gas sensors. As a leading TiO2 powder rutile manufacturer, our factory epitomizes the confluence of cutting-edge technology and unwavering commitment to quality.
