  • Applications

    Chemical name: 2,4-Dodecadien-1-ol, (2E,4E)-; CAS 18485-38-6 is a long-chain allylic alcohol that is typically evaluated as a fragrance ingredient and synthesis intermediate. In perfumery, it can function as an odorant and, owing to its molecular structure, may contribute to fixation and longevity of fragrance blends. In cosmetics and personal care, it may be used as a fragrance component and skin-contact carrier, with potential emollient and formulation roles in specialty products. In household products and cleaning formulations, it may serve as a scent carrier or odorant to impart fresh notes. In industrial manufacturing, it is often considered a building block for the synthesis of fragrance esters and related aroma compounds. It may also be used in polymers or coatings as a fragrance additive or processing aid in niche applications, subject to regulatory limits.
