  • Applications

    1,2-Octanediol (CAS 1117-86-8) is used as a humectant and solvent in cosmetics and personal care formulations, aiding moisturization and dissolution of active ingredients. It also serves as a processing aid and co-solvent in household and industrial cleaners, coatings, and inks. In polymer and materials manufacturing, the diol acts as a building block for polyesters and polyurethanes and can function as a chain extender or crosslinking component in selected systems. As a versatile diol, it is often evaluated as an intermediate in chemical synthesis and formulation development, with usage levels and handling governed by formulation requirements and local regulations.
