Frequently Asked Questions
What is triethanolamine used for?
Triethanolamine (TEA, CAS 102-71-6, C6H15NO3) is a trifunctional amino-alcohol and weak base. It is used to make surfactants and emulsifiers, as a pH adjuster and neutralizer, as a corrosion inhibitor in metalworking and cutting fluids, and as an intermediate for cement additives, waxes, polishes, and petroleum demulsifiers.
Is triethanolamine the same as triethylamine?
No. Triethanolamine (C6H15NO3, CAS 102-71-6) is an amino-alcohol with three hydroxyl groups, while triethylamine (C6H15N, CAS 121-44-8) is a tertiary amine with no hydroxyl groups. They differ in structure, CAS number, and use despite the similar names.
Is triethanolamine an acid or a base?
Triethanolamine is a weak base. This is why it is widely used as a neutralizer, pH adjuster, and alkalinity source in formulated products and metalworking fluids.
What is the HS code and formula for triethanolamine?
Triethanolamine has formula C6H15NO3 and CAS 102-71-6. It is classified under HS code 2922.15, the dedicated heading for triethanolamine.
How do I get a bulk quote for triethanolamine?
RawSource supplies triethanolamine in drums, totes, and IBCs for industrial and formulation use. We do not publish fixed prices; request a quote for your volume and grade, and we will include the SDS and CoA.
What is the REACH and TSCA regulatory status of Triethanolamine (TEA)?
Triethanolamine (TEA) (CAS 102-71-6) is subject to U.S. TSCA Inventory requirements; supplying it into the EU requires valid REACH registration ((EC) No 1907/2006). RawSource cannot verify a third-party supplier's registrations — buyers should require documented TSCA and REACH compliance for their jurisdiction and volume (EC 203-049-8).
