  • Applications

    Cyperene (CAS 2387-78-2) is a sesquiterpene hydrocarbon occurring in Cyperus essential oils and related botanicals, and is employed primarily as a fragrance ingredient and a fixative in perfumery and cosmetics/personal care. In practice, it is used as a fragrance component in household cleaning products as well, contributing to the overall scent profile of cleaning formulations. It can serve as an intermediate or starting material in fragrance synthesis for industrial manufacturing, and is evaluated for use as a scent additive in coatings and inks. Subject to local regulations and formulation limits.
