It is a tertiary amine and triol used as a buffer, masking agent, emulsifier, and pH adjuster.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChemical identity.\u003c\/strong\u003e Triethanolamine (2,2',2''-nitrilotriethanol, CAS 102-71-6, C6H15NO3, 149.19 g\/mol) combines a basic nitrogen with three hydroxyl groups. It mixes completely with water and dissolves in alcohols, acetone, and chloroform.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePhysical properties.\u003c\/strong\u003e TEA has a density of about 1.12 g\/mL, melts near 21 °C, and boils with decomposition near 335 °C. Its flash point is high, about 179-190 °C. Because it can solidify in cool rooms, warm it gently if it thickens or crystallizes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eA weak base and buffer.\u003c\/strong\u003e Triethanolamine is a weak base; a 0.1 N aqueous solution has a pH of about 10.5. Its conjugate acid buffers in the mildly alkaline range, so biochemists and analytical chemists use TEA-based buffers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMasking agent in titrations.\u003c\/strong\u003e In complexometric titrations, triethanolamine masks iron, aluminum, and manganese by binding them so they do not interfere with EDTA determinations of calcium and magnesium. It is also used to dissolve Eriochrome Black T for indicator solutions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEmulsifier and formulation ingredient.\u003c\/strong\u003e Neutralized with fatty acids, triethanolamine forms soaps that act as emulsifiers, which is why it appears in cosmetics, lotions, cutting fluids, and cleaning formulations as a pH adjuster and emulsifying agent.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndustrial uses.\u003c\/strong\u003e TEA is used as a cement grinding aid, corrosion inhibitor, gas-scrubbing absorbent for acid gases, and intermediate in surfactant production.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBuffer preparation.\u003c\/strong\u003e To prepare a TEA buffer, dilute triethanolamine in water and titrate to the target pH with hydrochloric acid. TEA buffers are used in enzyme assays and as alkaline media for some colorimetric methods.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHandling at a glance.\u003c\/strong\u003e Triethanolamine causes serious eye irritation and is hygroscopic. Wear safety glasses and gloves, keep the container closed, and store it at room temperature away from strong acids and oxidizers.
