Diethanolamine (DEA)

Diethanolamine (DEA) is a colorless to pale yellow liquid used as an emulsifier, surfactant, and corrosion inhibitor. It is commonly applied in cosmetics, personal care products, and industrial formulations. DEA helps stabilize emulsions and adjust pH levels in products. Proper handling is necessary, as it can cause skin and eye irritation and may be toxic in high concentrations.
