  • Applications

    Isomenthone, (+/-)- (CAS number: 18309-28-9) is a monoterpene ketone occurring in peppermint oil and related essential oils; in industry it is primarily used as a fragrance ingredient to impart minty, herbal notes in perfumery and personal care products. It may also be used as a flavor/aroma component in select flavor formulations, and serves as a synthetic intermediate for mint-related terpenoids such as menthol. Additionally, it is employed as a fragrance additive in household cleaning products, air fresheners, and other consumer care items, and can be incorporated in coatings, inks, and plastics to provide a minty scent. Its use is subject to local regulations and formulation limits.
