Diethanolamine

Diethanolamine (DEA) is a secondary amine and diol, appearing as a colorless to light yellow viscous liquid with a mild ammonia-like odor. It contains both hydroxyl groups and an amine group, making it highly versatile for neutralization, emulsification, and chemical synthesis. DEA is widely used as an absorbent for acid gases and as a key intermediate in the production of surfactants and other specialty chemicals.
