an organic compound, of molecular formula C₆H₅CH₂OH, that occurs combined with carboxylic acids (as esters) in balsams and oils of jasmine and other flowers. Several of its natural and synthetic esters have long been used in perfumery; the alcohol itself has become important in the second half of the 20th century as a developer booster in the processing of colour motion-picture film and as a dyeing assistant for filament nylons. Benzyl alcohol is manufactured by the hydrolysis of benzyl chloride in the presence of soda ash.
