  • Applications

    Kaurenol (CAS 2300-11-0) is used in fragrance chemistry as an odorant and may function as a fixative in perfumery formulations; it may also be employed as a fragrance ingredient in cosmetics and personal care products. In industrial manufacturing, it is evaluated as an intermediate for the synthesis of kaurane-type diterpenoids and related fragrance compounds. It can be incorporated into household products as a fragrance component to impart characteristic notes, subject to formulation limits and local regulations.
