Diethanolamine appears as oily colorless liquid or solid white crystals. Slight rotten fish or ammonia odor. Denser than water. Diethanolamine is a member of the class of ethanolamines that is ethanolamine having a N-hydroxyethyl substituent. It has a role as a human xenobiotic metabolite. It is functionally related to an ethanolamine. Diethanolamine is a metabolite found in or produced by Escherichia coli. At room temperature, diethanolamine was a colorless crystalline solid. Mild ammonia odor. Soluble in water and alcohol, soluble in acetone, slightly soluble in ether and benzene, insoluble in carbon tetrachloride and heptane. Diethanolamine can absorb water and carbon dioxide in the air, and its freezing point is significantly reduced after mixing with water. Diethanolamine is flammable. The lower explosive limit is 1.6% (volume fraction) and the spontaneous combustion temperature is 662 ℃. Flammable in case of open flame and high heat. Reactions with strong oxidants may occur. Thermal decomposition of the emission of toxic ammonia oxidation flue gas.

Diethanolamine is an important corrosion inhibitor, which can be used in boiler water treatment, automobile engine coolant, drilling and cutting oil and other types of lubricating oil. It is also used in natural gas as an absorbent for the purification of acid gases. It is used as an emulsifier in various cosmetics and pharmaceuticals. In the textile industry as a lubricant, but also can be used as wetting agent and softening agent and other raw materials for organic synthesis. Diethanolamine is used in cutting oils, soaps, shampoos, cleaners, polishers, cosmetics, and pharmaceuticals. It is also used as an intermediate in the rubber chemicals industry, as a humectant and softening agent, and as an emulsifier and dispersing agent in various agricultural chemicals.
