  • Applications

    Ethanolamine Hydrochloride (CAS 2002-24-6) is a salt of ethanolamine used primarily as a chemical intermediate and reagent for the synthesis of amino-alcohol derivatives. Practical applications include: acting as a building block for surfactants and polymer additives; serving as a source of ethanolamine for pharmaceutical synthesis and as a buffering/pH-adjusting component in cosmetic and personal-care formulations; functioning as an intermediate in dye and textile chemical processes; and being used in cleaning formulations and other industrial products as a buffering agent or active component.
