Ethanolamine, also known as 2-aminoethanol or monoethanolamine is an organic chemical compound which is both primary amine (organic compounds in the functional groups that has a basic nitrogen atom with a lone pair) and primary alcohol (alcohol having hydroxyl group connected to carbon atom). Ethanolamine is a corrosive, colorless, flammable, viscous and toxic liquids substance which is used in solutions and dispersions to scrub acids, feedstock material in the manufacture of detergents, emulsification agents, varnishes & polishes and other chemical intermediaries. Ethanolamine acts as a weak base compound (chemical base that does not ionize fully in an aqueous solution). Ethanolamine is the second-most-abundant head group substances for phospholipids. Ethanolamine is also used in messenger molecules such as palmitoylethanolamide. Ethanolamine is also referred as a class of antihistamines including carbinoxamine, clemastine, dimenhydrinate, diphenhydramine and doxylamine. In 2012, more than one third of ethanolamines were used in the manufacturing of surfactants.
