  • Applications

    1,2-Tetradecanediol (CAS 21129-09-9) is commonly used in cosmetics and personal care as an emollient and humectant, helping to soften and moisturize skin and hair. It also serves as a polyol in polymer and resin synthesis, acting as a flexible chain extender or crosslinker for polyurethane and polyester systems. In coatings and inks, it can function as a polyol component to improve film flexibility and adhesion in polyurethane-based coatings and adhesive formulations. In industrial manufacturing, this diol may act as a plasticizer for thermoplastic polymers and as an intermediate for the synthesis of esters and surfactants, supporting processing and formulation performance. Its exact use depends on local regulations and formulation limits.
