URL: http://www.loc.gov/rr/scitech/mysteries/sunscreen.html Description: This page describes how "sunscreen works by combining organic and inorganic active ingredients. Inorganic ingredients like zinc oxide or titanium oxide reflect or scatter ultraviolet (UV) radiation. Organic ingredients like octyl methoxycinnamate (OMC) or oxybenzone absorb UV radiation, dissipating it as heat." Includes links to related sites and a short bibliography.
