Ethanolamine (CAS 141-43-5), also known as Monoethanolamine (MEA) or 2-Aminoethanol, is a clear, viscous liquid with both an amine group (–NH₂) and a hydroxyl group (–OH). These functional groups make it highly water-soluble and chemically reactive, which is why ethanolamine is widely used in cosmetics, detergents, and industrial cleaning products.
But is ethanolamine itself a surfactant? The answer is not exactly-pure ethanolamine is not a conventional surfactant, but it is a raw material used to produce many surfactant compounds.
What is CAS number 141-43-5?

Ethanolamines such as MEA are common ingredients in cleaning products like floor and tile cleaners, as well as laundry detergents. As surfactants in these products, ethanolamines help remove dirt, grease and stains. DEA is a common ingredient in industrial cleaning products, such as engine degreasers and industrial strength detergents, due to its ability to break down oil and grease.
TEA is used as a surfactant in agrochemicals, to help pesticides disperse into crops, which then helps repel insects from the crops. As a petroleum demulsifier, TEA helps separate oil from water and other substances. In cement additives, TEA helps advance setting and/or hardening of cement. It is also a corrosion inhibitor in steel and zinc materials used in building and construction.
In cosmetics and personal care products, ethanolamine content is regulated to ensure safety, as high concentrations can cause skin and eye irritation. Cosmetic-grade MEA derivatives meet standards set by regulatory bodies such as the EU Cosmetic Regulation and FDA guidelines.
