  • Applications

    2,6,10,14,18-Pentamethyl-15-eicosene-2,13-diol (CAS 255833-55-7) is a branched long-chain diol used as a polyol component in polymer synthesis, notably in polyurethane and polyester resins, where it can function as an intermediate and/or crosslinking/chain-extending agent to impart flexibility and improved durability; in coatings and inks, it may serve as a diol polyol for polyurethane-based systems to enhance film properties and wear resistance; in adhesives, it can act as a diol linker or chain-extender to boost adhesion and elasticity; in cosmetics and personal care, it may be used as an emollient or precursor to esters for cosmetic formulations; and in industrial manufacturing, it could be considered a specialty polymer intermediate or compatibility additive for plastic formulations, subject to regulatory constraints and formulation limits.
