China, the United States, and Germany are the leading exporters of Diethanolamine (CAS 111-42-2), collectively accounting for over 50% of global export value in 2023–2024, while India, South Korea, and Brazil represent the largest importers. Diethanolamine prices have remained relatively stable amid moderate demand growth from surfactant and gas treatment applications. Export volumes from China increased by approximately 7% year-on-year in 2024, while U.S. exports declined slightly, reflecting shifting regional supply dynamics and evolving downstream formulation requirements.
Diethanolamine (DEA) is a colorless, viscous liquid with a mild ammonia-like odor and low volatility; it is hygroscopic, miscible with water, and has a melting point of 28 °C and a boiling point of 269 °C. It is classified as a secondary alkanolamine and an organic nitrogen compound. DEA serves primarily as a chemical intermediate in the synthesis of surfactants, corrosion inhibitors, and gas-treating agents. Its main industrial applications include the production of ethanolamides and morpholine derivatives for use in personal care formulations, agrochemicals, lubricant additives, and natural gas sweetening systems.
Diethanolamine similar to triethanolamine (T775580) is used as a surfactant. It also has the potential to be a corrosion inhibitor by means of chemisorption.
The USP32–NF27 describes diethanolamine as a mixture of ethanolamines consisting largely of diethanolamine. At about room temperature it is a white, deliquescent solid. Above room temperature diethanolamine is a clear, viscous liquid with a mildly ammoniacal odor.
