  • Applications

    1,2-Dodecanediol (CAS 1119-87-5) is primarily used as a diol monomer and chain extender in polymer production, supporting the formation of polyurethanes and polyesters and related resin systems for coatings and alkyd resins; it also serves as a diol building block in specialty plastics and rubbers. It can also function as a plasticizer or additive in polymer formulations and lubricants. In cosmetics and personal care, it may be used as a solvent or conditioning agent in formulations; in cleaning and industrial formulations, it can act as a solvent or co-solvent component.
