Glossary Diethanolamine

chemical compound used in shampoos and cosmetics for foaming

Diethanolamine (DEA) is a chemical compound used in various industrial and consumer products, such as shampoos, soaps, and cosmetics, to create a creamy texture and stabilize foam. It is a colorless, viscous liquid that can react with other ingredients to form potentially harmful substances, so its use is regulated in many countries.
