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, is the naturally occurring oxide of titanium, chemical formula TiO 2.When used as a pigment, it is called titanium white, Pigment White 6 (PW6) , or CI 77891. Generally it is sourced from ilmenite, rutile and anatase.It has a wide range of applications, from paint to sunscreen to food colouring. When used as a food colouring, it has E number E171.n cosmetic and skin care products, titanium dioxide is used as a pigment, sunscreen and a thickener. It is also used as a tattoo pigment and in styptic pencils. Titanium dioxide is produced in varying particle sizes, oil and water dispersible, and in certain grades for the cosmetic industry.
