Talc
TALC
The softest mineral known, a hydrated magnesium silicate whose stacked platelets slide over one another under a fingertip; the material that gives a face powder its slip.

Titanium Dioxide
TITANIUM DIOXIDE
The manufactured white that replaced lead: a titanium oxide with a refractive index high enough to make it the most opaque white a cosmetic chemist can use, and a permitted mineral ultraviolet filter.

Tocopherol (Vitamin E)
TOCOPHEROL
A fat-soluble antioxidant, identified in 1922 as a dietary factor required for reproduction in rats, which protects the oils in a cosmetic from going rancid rather than protecting the product from microbes.

Trimethylsiloxysilicate
TRIMETHYLSILOXYSILICATE
A brittle silicone resin built from trimethylsilyl caps around a silica-like core; dissolved in a volatile solvent and left behind when that solvent evaporates, it is the film that makes a lipstick transfer-resistant.
