Diethanolamine
Diethanolamine is a colorless to pale yellow, viscous liquid with a mild ammonia-like odor. It is a secondary amine and diol, widely used in various industrial, pharmaceutical, and cosmetic applications. DEA is highly soluble in water and many organic solvents. It acts as an intermediate in the synthesis of surfactants, emulsifiers, corrosion inhibitors, and pharmaceuticals. It is valued for its alkalinity, emulsifying properties, and ability to form stable complexes with fatty acids.
