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.
In 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.itanium dioxide occurs in nature as the well-known minerals rutile, anatase and brookite, and additionally as two high pressure forms, a monoclinic baddeleyite-like form and an orthorhombic Î±-PbO2 -like form, both found recently at the Ries crater in Bavaria. It is mainly sourced from ilmenite ore.
