Diethanolamine (DEA) is a multifunctional amino alcohol widely used as a chemical intermediate and processing aid. It is used in the production of surfactants, detergents, emulsifiers, corrosion inhibitors, pharmaceuticals, agrochemicals, rubber chemicals, polyurethane catalysts, and gas treatment formulations. It is also used as a neutralizing agent and pH regulator in industrial and cosmetic formulations.
