Inorganic chemicals generally used in the sunscreens are zinc oxide and titanium oxide. Both of them are capable of absorbing and scattering UV light.

At present, FDA has approved 17 ingredients for use in sunscreen, including titanium dioxide and zinc oxide. Many chemical compounds are under FDA consideration.
