  • Applications

    3-Undecen-2-one, 10-hydroxy-3,6,10-trimethyl- (CAS 68141-19-5) is primarily used as a fragrance ingredient and odorant with potential as a fixative to extend scent in perfumery. In the fragrance and cosmetic industries, it may serve as a fragrance component and/or fixative in personal care products such as perfumes, lotions, shampoo, and cleansers. It can also be used as a fragrance ingredient in household products and cleaning agents to impart a characteristic odor. In the chemical industry, it may be evaluated as an intermediate for the synthesis of other aroma compounds. In coatings and inks sectors, it may be considered as a fragrance additive compatible with formulations, subject to local regulations and formulation constraints.
