Phenyl salicylate, or salol, is a chemical substance, introduced in 1886 by Marceli Nencki of Basel. It can be created by heating salicylic acid with phenol. Once used in sunscreens, phenyl salicylate is now used in the manufacture of some polymers, lacquers, adhesives, waxes and polishes.[1] It is also used frequently in school laboratory demonstrations on how cooling rates affect crystal size in igneous rocks.

Salol reaction[edit]

In the salol reaction, phenyl salicylate reacts with o-toluidine in 1,2,4-trichlorobenzene at elevated temperatures to the corresponding amide o-Salicylotoluide.[3] Salicylamides are one type of drug.


It has been used as an antiseptic[4] based on the antibacterial activity upon hydrolysis in the small intestine.[citation needed]

It acts as a mild analgesic.[5]
