Diethanolamine

Diethanolamine (DEA) is a secondary amine and diol compound that combines both amine and alcohol functionality, making it a highly versatile material in industrial manufacturing, consumer products, and specialty applications. Widely used in the production of surfactants, emulsifiers, and detergents, DEA is a key ingredient in personal care, household cleaning, textiles, and industrial formulations. Its dual functionality also allows it to act as a neutralizing and buffering agent, ensuring precise pH balance, stability, and performance in chemical systems.

Beyond consumer and cleaning products, Diethanolamine plays a crucial role in gas treatment, corrosion inhibition, and agrochemical synthesis. It is widely applied in removing CO₂ and H₂S from natural gas streams, extending its importance to the energy sector. DEA also serves as a key intermediate in herbicide and crop protection formulations, as well as in pharmaceuticals and specialty coatings. With its balance of reactivity, compatibility, and multifunctional chemistry, Diethanolamine remains an indispensable raw material for industries including construction, automotive, agriculture, and chemical manufacturing.
