Titanium dioxide nanoparticles
Titanium dioxide, also known as titanium(IV) oxide or titania, is the naturally occurring oxide of titanium.
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. Titanium dioxide nanoparticles have atleast one dimension measuring from 1 to 100 nanometers.
