What Is the Difference Between Triethanolamine and Diethanolamine: Understanding Their Formulation Functions, Application Differences, and Selection Logic from a Molecular-Structure Perspective

Triethanolamine, abbreviated as TEA, and diethanolamine, abbreviated as DEA, both belong to the ethanolamine family of compounds. Their molecules contain both amine groups and hydroxyethyl structures, giving them a certain degree of hydrophilicity, alkalinity, and salt-forming ability.
