  • Applications

    (2,2-Bis((3,7-dimethyl-2,6-octadienyl)oxy)ethyl)benzene, CAS 67634-02-0, is used as a fragrance ingredient and fixative in perfumery and cosmetics, benefiting from the lipophilic farnesyl groups that help retain fragrance in skin-contact products and in matrices. It can also function as a solvent or carrier for fragrances in personal care and household products, supporting aroma delivery and sensory performance. In coatings and inks, it may act as a fragrance additive and help control aroma release within the binder matrix. In polymers/plastics, it can be evaluated as a fragrance additive or a plasticizer/processing aid to influence fragrance release and material properties. It may also be explored as an intermediate in the synthesis of other terpenoid-based fragrance compounds.
