Chemical Properties

(1R)-(-)-Menthyl acetate oeccurs in peppermint oils. It is a colorless liquid with a fresh, fruity, peppermint odor.
(?)-Menthyl acetate is prepared by acetylation of (?)-menthol (e.g., with acetic anhydride). It is used mainly in peppermint flavors and reconstituted peppermint oils, but also to a small extent in perfumery.

Safety Profile

Low toxicity by ingestion and skin contact. A skin irritant. When heated to decomposition it emits acrid smoke and irritating fumes.
