Titanium dioxide nanoparticles (TiO(2)-NPs, <100 nm) are increasingly being used in pharmaceuticals and cosmetics due to the unique properties derived from their small sizes. However, their large surface-area to mass ratio and high redox potential may negatively impact human health and the enviro …

Titanium dioxide (E 171) is authorised as a food additive in the EU according to Annex II of Regulation (EC) No 1333/2008. The safety of the food additive E 171 was re-evaluated by the EFSA ANS Panel in 2016 in the frame of Regulation (EU) No 257/2010, as part of the re-evaluation programme for food additives authorised in the EU before 20 ...

Abstract Titanium dioxide was supported on hollow glass microspheres (HGM) via a sol-gel route to prepare xTiO2-HGM composites. The growth and aggregation of the anatase TiO2 crystals were restrained after supporting them. A thin layer of TiO2 was coated on the external surface of the hollow glass microspheres when the TiO2 content was not high.

Revised IDLH: 5,000 mg/m 3 Basis for revised IDLH: The available toxicological data contain no evidence that an acute exposure to a high concentration of titanium dioxide would impede escape or cause any irreversible health effects within 30 minutes. However, the revised IDLH for titanium dioxide is 5,000 mg/m 3 based on being 500 times the OSHA PEL of 10 mg/m 3 promulgated in 1989 (500 is an ...

Titanium dioxide (TiO2) is a natural oxide of the element titanium with low toxicity, and negligible biological effects. The classification as bio-inert material has given the possibility to normal-sized (>100 nm) titanium dioxide particles (TiO2-NPs) to be extensively used in food products and as ingredients in a wide range of pharmaceutical products and cosmetics, such as sunscreens and ...

12%On the other hand the replacement of a small amount of titanium oxide as a light-reflecting high-coverage pigment by HGM reduces its amount, which in turn lowers the production cost of the article. It is also necessary to take account of the fact that the density of HGM is 15 – 20 times lower than that of TiO 2 — 0.22 versus 4.1 g/cm 3.
