Metabolite Identification
Common NameBenzyl salicylate
DescriptionBenzyl salicylate, also known as fema 2151, belongs to the class of organic compounds known as o-hydroxybenzoic acid esters. These are benzoic acid esters where the benzene ring is ortho-substituted with a hydroxy group. Benzyl salicylate is an extremely weak basic (essentially neutral) compound (based on its pKa). Trace impurities may have a significant influence on the odour. Benzyl salicylate is a sweet, balsam, and clean tasting compound. Outside of the human body, Benzyl salicylate has been detected, but not quantified in, cloves and herbs and spices. This could make benzyl salicylate a potential biomarker for the consumption of these foods. It occurs naturally in a variety of plants and plant extracts and is widely used in blends of fragrance materials. It is used as a solvent for crystalline synthetic musks and as a component and fixative in floral perfumes such as carnation, jasmine, lilac, and wallflower. Benzyl salicylate is a salicylic acid benzyl ester, a chemical compound most frequently used in cosmetics as a fragrance additive or UV light absorber. There is some evidence that people may become sensitized to this material and as a result, there is a restriction standard concerning the use of this material in fragrances by the International Fragrance Association. It appears as an almost colorless liquid with a mild odor described as "very faint, sweet-floral, slightly balsamic" by those who can smell it, but many people either can't smell it at all or describe its smell as "musky".
