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).
Importantly, TiO2 also has a very high refractive index (its ability to scatter light), even higher than diamond. This makes it an incredibly bright substance and an ideal material for aesthetic design use.
French researchers studied how and where E171 nanoparticles enter the bloodstream, first studying the route through pigs and then in vitro with human buccal cells, for a 2023 study published in the journal Nanotoxicology. The research showed that the nanoparticles absorbed quickly through the mouth and then into the bloodstream, before damaging DNA and hindering cell regeneration.
Manufacturers get titanium dioxide from minerals called brookite, rutile, and anatase. It's processed into a powder and refined to meet strict safety guidelines.
1. Properties: white powder, a mixture of zinc sulfide and barium sulfate.
4. Solar Cells The photovoltaic industry is another critical area where anatase TiO2 is making an impact. As a semiconductor, it plays a role in dye-sensitized solar cells (DSSCs), providing a pathway for improving energy conversion efficiency in sustainable energy solutions.
1.Mainly used in latex paints, water-based paints, inks, rubber, plastics, etc., replacing 30% of rutile-type titanium dioxide in latex paints, still maintaining the original film properties, and has the effect of reducing costs.

The photocatalytic activity of titanium dioxide results in thin coatings exhibiting self-cleaning and disinfecting properties under exposure to ultraviolet radiation. Alloys are characterized by being lightweight and having very high tensile strength (even at high temperatures), high corrosion resistance, and an ability to withstand extreme temperatures and thus are used principally in aircraft, pipes for power plants, armour plating, naval ships, spacecraft, and missiles.
