  • Applications

    5-Undecanol (CAS 37493-70-2) is a long-chain secondary fatty alcohol that is mainly used as an intermediate and formulation component. In industrial manufacturing, it is used to synthesize undecyl esters and other derivatives for lubricants, plasticizers, and surfactants. In perfumery and cosmetics, it can be used as a fragrance ingredient or a solvent/emollient in specialty formulations. In household cleaning products and detergents, it can function as a solvent or co-surfactant component within surfactant systems. In coatings and inks, it may be employed as a solvent or processing aid, contributing to film formation and viscosity control.
