  • Applications

    Curcolone, CAS 17015-43-9, is regarded as a fragrance ingredient and odorant in many perfumery and cosmetic formulations, and it may serve as a fragrance fixative in some applications. In cosmetics and personal care, it may be used as a fragrance component in lotions, creams, and cleansing products. In household products, Curcolone may be added to cleaning solutions and air-freshening formulations to impart a pleasant scent. As an intermediate in organic synthesis, it may be used in industrial manufacturing to build more complex compounds. In coatings and inks, it may be evaluated as a fragrance additive or odorant component for scented formulations. Its use is subject to local regulations and formulation limits.
