  • Applications

    3,6,9,12,15,18,21-Heptaoxaheptatriacontan-1-ol (CAS 4486-31-1) is a long-chain polyether alcohol that is commonly used as a nonionic surfactant and emulsifier. In cosmetics and personal care, it acts as an emulsifier and solubilizer for oils and fragrances. In household and industrial cleaners, it provides surfactant and wetting properties to enhance cleaning and dispersion. In coatings, inks, and polymer formulations, it serves as a wetting and dispersing agent that helps pigment dispersion and emulsion stability. It can function as a humectant or co-solvent in cosmetic formulations. In industrial manufacturing and polymer processing, it is used as a processing aid and lubricant to improve flow and reduce friction. Subject to local regulations and formulation limits.
