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 dioxide, also known as titanium(IV) oxide or titania, with its molecular formula TiO2 and molecular weight 79.87, is a kind of white to almost white powder.The properties of Titanium dioxide is also have two sides: the physical properties of titanium dioxide and the chemical properties of titanium dioxide.
