Applications

● Gas Purification: Used to remove acidic gases such as carbon dioxide and hydrogen sulfide from natural gas and refinery gases. Like monoethanolamine (MEA), DEA is commonly used in gas purification processes.

● Detergents and Cleaners: Acts as a surfactant in the production of detergents, soaps, and other cleaning products, enhancing their ability to remove dirt and grease.

● Cosmetics and Personal Care Products: Used to manufacture emulsifiers, thickeners, and foam stabilizers, commonly found in skincare products, shampoos, and body washes. DEA helps these products maintain a uniform texture and stable foam.

● Chemical Raw Material: Used in the synthesis of other chemicals such as ethanolamine salts, ethanolamine esters, and various surfactants. It is an important intermediate in many industrial chemical reactions.

● Agriculture: Serves as an intermediate in the production of certain pesticides and herbicides, improving their effectiveness and stability.

● Metal Processing: Used as a corrosion inhibitor and lubricant in metalworking fluids, protecting metal surfaces and extending equipment life.

● Textile Industry: Acts as a dyeing assistant and finishing agent, improving the colorfastness and feel of textiles.
