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 a transition metal which is very strong and light (4.4 gm/cm3). It has a high melting point (1800Â°C) and finds application in aircraft wings, particularly at points which are subjected to the high heat of exhaust. Titanium dioxide in powder form is very white and is used to advantage as a pigment in special paints and face powders. Titanium dioxide, TiO2, in crystalline form appears in the mineral rutile. It may be colored by small amounts of other metal oxides and has been used for gems. Titanium dioxide also makes up the minerals Brookite and anatase. Titanium and iron together form the oxides ilmenite, FeTiO3, and pseudobrookite, Fe2TiO5.
