Cinoxate is an organic compound used as an ingredient in some types of sunscreens. It is an ester formed from methoxycinnamic acid and 2-ethoxyethanol. It is a slightly yellow viscous liquid that is insoluble in water, but miscible with alcohols, esters, and vegetable oils.

It protects skin against the sun by absorbing UV-A[citation needed] and UV-B rays.
