Titanium dioxide - Wikipedia

Titanium dioxide, also known as titanium(IV) oxide or titania /taɪˈteɪniə/, 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, including paint, sunscreen, and food coloring. When used as a food coloring, it has E numberE171. World production in 2014 exceeded 9 million tonnes. It has been estimated that titanium dioxide i

Introduction. Because zinc oxide and titanium dioxide are very effective at blocking UV-light, these are largely used in sunscreens but the fact that their common forms (i.e. particles in the micrometre range) have a white colour made them less appealing to customers for application on skin. However, when they are in the form of nanoparticles (NPs), they become transparent and therefore ...
