  • Applications

    3,7,11-Trimethyldodec-1-en-3-ol (CAS 33185-23-8) is mainly considered a fragrance ingredient and can act as a fixative due to its long hydrophobic chain, and it also serves as an intermediate in the synthesis of other aroma compounds. In the fragrance and cosmetics industries, it is used as a fragrance component or aroma booster in products such as perfumes, lotions, soaps, and shampoos. In household and cleaning products, it may be added to improve scent; in industrial manufacturing it provides a building block for the synthesis of additional fragrance materials. It may also be evaluated for flavor/aroma applications in certain food formulations, depending on local regulations.
