  • Applications

    Cyclohexanol, 5-methyl-2-(1-methylethenyl)- (CAS 7786-67-6) is a monoterpene alcohol with a soft herbal–minty–woody odor, used as a fragrance ingredient in perfumes, soaps, cleaners, and air care; as a flavor modifier providing mint/citrus/herbal notes at regulatory-compliant levels; as an intermediate to esters (e.g., dihydrocarvyl acetate), related ketones (dihydrocarvone), and other terpene derivatives; as a bio-based solvent/co-solvent and fragrance carrier in coatings, inks, and “green” cleaning formulations; its antimicrobial and deodorizing properties are leveraged in household and personal care, and it serves in sensory research and asymmetric synthesis as a chiral pool building block; practical use typically considers volatility, surfactant compatibility, and compliance with local safety and regulatory standards.
