Menthol Structure

Synonyms: 2-Isopropyl-5-methylcyclohexanol, Hexahydrothymol, Peppermint camphor, 3-p-Menthanol, 5-Methyl-2-(1-methylethyl)cyclohexanol

Menthol is a cyclic monoterpene alcohol that occurs naturally in the essential oils of plants from the Mentha genus, most notably peppermint (Mentha × piperita) and corn mint (Mentha arvensis). Commercially, it is produced either by fractional crystallization from mint oil or through synthetic routes, yielding a product with a characteristic cooling, refreshing taste and a distinct minty odor. The synthetic grade, which dominates the global market, offers consistent quality and stable supply for industrial applications.

With a melting point near body temperature, menthol is prized for its unique physiological cooling effect, activating TRPM8 receptors without actual temperature change. This property, combined with its antimicrobial, analgesic, and penetration-enhancing characteristics, makes it indispensable in pharmaceuticals, personal care, food, and flavor industries. As a leading supplier, we provide high-purity menthol crystals and flakes that meet stringent pharmacopeial standards, ensuring reliability for formulators worldwide.
