Food grade titanium dioxide is really common and not so nano. The titanium dioxide used by Dunkin' Brands and many other food producers is not a new material, and it's not really a nanomaterial either. Nanoparticles are typically smaller than 100 nanometers in diameter.Yet most of the particles in food grade titanium dioxide are larger than this.itanium dioxide (which isn't the same thing as the metal titanium) is an inert, insoluble material that's used as a whitener in everything from paper and paint to plastics.
Titanium is used to make hip replacements. Titanium is a light metal but very strong, e.g. it is as strong as steel but 45% lighter. For these properties it is used to make lightweight alloys for aircraft, bikes and laptop computers.The compound Titanium dioxide (TiO 2) absorbs UV light and is used in sunscreen.itanium is resistant to corrosion by sea water and therefore is used on parts of ships. The non-reactive properties of titanium make it ideal for use in the body as hip replacements and pacemakers, which won't be attacked by body fluids.
