Pigment
Titanium dioxide is the most widely used white pigment because of its brightness and very high refractive index (n = 2.7), in which it is surpassed only by a few other materials. Approximately 4 million tons of pigmentary TiO2 are consumed annually worldwide. When deposited as a thin film, its refractive index and colour make it an excellent reflective optical coating for dielectric mirrors and some gemstones like "mystic fire topaz". TiO2 is also an effective opacifier in powder form, where it is employed as a pigment to provide whiteness and opacity to products such as paints, coatings, plastics, papers, inks, foods, medicines (i.e. pills and tablets) as well as most toothpastes. In paint, it is often referred to offhandedly as "the perfect white", "the whitest white", or other similar terms. Opacity is improved by optimal sizing of the titanium dioxide particles.
In ceramic glazes titanium dioxide acts as an opacifier and seeds crystal formation.
Titanium dioxide is often used to whiten skimmed milk; this has been shown statistically to increase skimmed milk's palatability.
Titanium dioxide is used to mark the white lines on the tennis courts of the All England Lawn Tennis and Croquet Club, best known as the venue for the annual grand slam tennis tournament The Championships, Wimbledon.
The exterior of the Saturn V rocket was painted with titanium dioxide; this later allowed astronomers to determine that J**2E3 was the S-IVB stage from Apollo *2 and not an asteroid.
Sunscreen and UV absorberIn 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 with varying coatings for the cosmetic industry. This pigment is used extensively in plastics and other applications for its UV resistant properties where it acts as a UV absorber, efficiently transforming destructive UV light energy into heat.
Titanium dioxide is found in almost every sunscreen with a
physical blocker because of its high refractive index, its strong
UV light absorbing capabilities and its resistance to
discolouration under ultraviolet light. This advantage enhances
its stability and ability to protect the skin from ultraviolet
light. Sunscreens designed for infants or people with sensitive
skin are often based on titanium dioxide and/or zinc oxide, as
these mineral UV blockers are believed to cause less skin
irritation than other UV absorbing chemicals. The titanium
dioxide particles used in sunscreens have to be coated with
silica or alumina, because titanium dioxide creates radicals in
the photocatalytic reaction. These radicals are carcinogenic, and
could damage the skin.
