(1R)-(-)-Menthyl acetate Usage And Synthesis
Chemical Properties(1R)-(-)-Menthyl acetate occurs 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.
UsesL-Menthyl Acetate, and its derivatives, is used as a penetration enhancers, to enhance the skin permeation of various drugs with differing lipophilicities, such as 5-aminolevulinic acid (ALA), 5-fluorouracil (5-FU), isosorbide dinitrate (ISDN), lidocaine (LD), etc.
DefinitionChEBI: (-)-Menthyl acetate is a p-menthane monoterpenoid.
Flammability and ExplosibilityNotclassified
Biochem/physiol ActionsTaste at 25 ppm
Safety ProfileLow toxicity by ingestion and skin contact. A skin irritant. When heated to decomposition it emits acrid smoke and irritating fumes.
