Diethanolamine - DEA

Pure diethanolamine (DEA) is a white solid at room temperature, but its tendency to absorb water and to supercool means it is often encountered as a colorless, viscous liquid. Diethanolamine is polyfunctional, being a secondary amine and a diol. Like other organic amines, diethanolamine acts as a weak base.
