Menthyl acetate is a natural monoterpene which contributes to the smell and flavor of peppermint. It is the acetate ester of menthol. Menthyl acetate constitutes 3-5% of the volatile oil of Mentha Arvensis Oil. Methyl acetate, also known as acetic acid methyl ester or methyl ethanoate, is a carboxylate ester. It is normally a flammable liquid with a characteristic, not unpleasant smell like certain glues or nail polish removers. Methyl acetate has characteristics very similar to its analog ethyl acetate. Methyl acetate is used as a solvent, being weakly polar and lipophilic. Methyl acetate has a solubility of 25% in water at room temperature. At elevated temperature its solubility in water is much higher. Methyl acetate is not stable in the presence of strong aqueous bases or acids.
