Diethanolamine丨CAS 111-42-2

Diethanolamine is a versatile alkanolamine widely used in chemical synthesis, pharmaceuticals, cosmetics, and industrial applications. It serves as a building block for the production of surfactants, emulsifiers, corrosion inhibitors, and gas treatment chemicals. In pharmaceuticals, diethanolamine is used as an intermediate in the synthesis of local anesthetics, anti-inflammatory agents, and other bioactive compounds. It is also applied in personal care products, including shampoos, conditioners, and skin care formulations, where it functions as a pH adjuster, stabilizer, and emulsifying agent. In industrial processes, diethanolamine is employed in the manufacture of metalworking fluids, textile chemicals, and detergents. It is also widely used in gas purification systems to remove acidic gases such as CO₂ and H₂S from natural gas and industrial emissions.

The benefits of diethanolamine arise from its multifunctional structure, containing both hydroxyl and amine groups, which allow it to participate in a wide range of chemical reactions. Its reactivity enables it to act as a nucleophile, chelating agent, or pH regulator, providing versatility in synthesis and formulation. Diethanolamine is highly soluble in water and compatible with many solvents and chemical systems, ensuring efficient processing and uniform incorporation into products. Its stability under standard storage conditions, combined with low toxicity in controlled applications, allows for safe handling in industrial, pharmaceutical, and cosmetic settings. These properties make it an effective intermediate and additive in diverse chemical, pharmaceutical, and industrial applications.
