What is Di Ethanol Amine?
Di Ethanol Amine (DEA), also written as Diethanolamine, is a colourless to pale yellow viscous liquid with the chemical formula HN(CH₂CH₂OH)₂. It is a secondary amine that simultaneously functions as an amine and a diol, giving it unique properties as a surfactant, pH adjuster, corrosion inhibitor, and chemical intermediate across multiple industries.
Polychem Industries supplies Di Ethanol Amine in industrial and technical grades to detergent manufacturers, cosmetic formulators, gas treatment facilities, and industrial chemical users across India and internationally. DEA is part of the ethanolamine family that includes Mono Ethanol Amine (MEA), Di Ethanol Amine (DEA), and Tri Ethanol Amine (TEA) — all available from Polychem Industries.
Available Grades
| Grade | Form | Purity | Standard | Applications |
|---|---|---|---|---|
| Industrial Grade | Colourless to pale yellow liquid | 99% | Industrial | Detergents, gas treatment, metalworking, agriculture |
| Technical Grade | Colourless liquid | 98.5% | Technical | Cosmetics, personal care, chemical synthesis |
Applications & Uses
Detergents & Surfactants
Reacts with fatty acids to form diethanolamides — widely used non-ionic surfactants and foam boosters in shampoos, liquid soaps, and cleaning products. DEA-based amides improve foam quality and viscosity in detergent formulations.
Gas Treatment (Acid Gas Removal)
One of the most important applications — DEA solutions are used in natural gas processing to selectively absorb and remove hydrogen sulphide (H₂S) and carbon dioxide (CO₂) from natural gas streams in the oil and gas industry.
Cosmetics & Personal Care
Used as a pH adjuster and emulsifier in cosmetic formulations. Reacts with fatty acids to form cocamide DEA and similar products widely used in shampoos and personal care products as foam boosters and thickeners.
Metalworking Fluids
Used as a corrosion inhibitor and pH buffer in metalworking and cutting fluids, protecting both ferrous and non-ferrous metal surfaces from oxidation during machining operations.
Agricultural Herbicides
Used as an emulsifier and pH adjuster in herbicide formulations. DEA salts of certain herbicide acids improve the stability and efficacy of the agricultural formulation.
Paints & Coatings
Used as a dispersant and pH adjuster in water-based paint and coating formulations. Helps stabilise pigment dispersions and improve the storage stability of water-based paints.
