What is a Triethanolamine (TEA)?

Triethanolamine (TEA) is an organic compound with the chemical formula C₆H₁₅NO₃, containing three hydroxyethyl groups. It appears as a colorless to pale yellow viscous liquid with a slight ammonia-like odor. TEA is highly soluble in water and alcohol and is commonly used as a surfactant, emulsifier, and pH buffer in various products, including cosmetics, shampoos, facial cleansers, household detergents, and industrial lubricants. In personal care products, it enhances foaming, improves texture, and stabilizes formulations. However, excessive use may cause skin irritation, so careful formulation and concentration control are essential for safe application.
