  • Applications

    1,2-Eicosanediol (CAS 39825-93-9) is used primarily as a diol monomer/chain extender in polyurethane and polyester polyol formulations for coatings, adhesives, and elastomers; as a processing aid and plasticizer to improve flexibility and compatibility in high-molecular-weight polymers; as an emollient and humectant in cosmetics and personal care products due to its long hydrocarbon chain; as a lubricant or lubricant additive component in specialty fluids and lubricants; and as a precursor for ester or ether derivatives that serve as surfactants or cleaners in industrial and consumer formulations.
