  • Applications

    3,6,9,12,15,18,21,24,27,30-Decaoxadotetracontan-1-ol (CAS 6540-99-4) is a long-chain polyether alcohol that is typically used as a reactive intermediate and specialty additive in polymer formulations. In polyurethane and other polymer syntheses, it can function as a polyether-derived intermediate or chain-terminating agent, helping to tailor molecular weight and flexibility. Its amphiphilic structure—a hydrophobic C40 backbone linked to a polyether head—enables it to act as a nonionic surfactant and emulsifier in coatings, cleaners, and personal care products, and as a processing aid or lubricant additive in plastics and elastomers. It may also be used as a component in cosmetic formulations and in household product recipes as a surfactant or compatibility additive. Subject to local regulations and formulation limits.
