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.
Zinc Oxide
ZINC OXIDE
The white that came between lead and titanium: a manufactured zinc oxide, mildly astringent and mildly soothing, now met as often in a mineral sunscreen as in a face powder.
