Diethanolamine (DEA)

Diethanolamine (DEA) is an organic compound with the chemical formula HN(CH₂CH₂OH)₂. At room temperature, it can be a colorless viscous liquid or a white solid with a slight ammonia odor. It is weakly alkaline and readily soluble in water and alcohol.It has both secondary amine functional groups and diol structures, making it an important raw material for organic synthesis. It is widely used in gas purification, detergents, cosmetics, pesticides (such as glyphosate), polyurethane, metal processing, and pharmaceuticals.
