  • Applications

    1,2-Hexacosanediol (CAS 97338-12-0) is a long-chain diol used as a versatile building block in industrial polymers and formulations. In practice, it often serves as a chain extender for polyurethane and polyester resins, supporting coatings, adhesives, and elastomeric materials. It can be used as a plasticizer or flexibilizer to tailor the mechanical properties of polymers in coatings and sealants. In cosmetics and personal care, it may function as an emollient or conditioning agent, helping to improve a smooth feel on skin or hair. It is also used as an industrial lubricant additive or viscosity modifier in synthetic lubricant systems. Additionally, it is employed as an intermediate for the synthesis of specialty surfactants or polymeric materials.
