Description
Triethanolamine (CAS 102-71-6), also known as TELA, TEOA, Trolamine, or H3TEA, is a tertiary amine and triol belonging to the ethanolamine family. It carries no assigned E-code. Supplied under EC number 203-049-8 with molecular formula C6H15NO3, it is classified within the amines category.
In coatings and adhesives, triethanolamine functions as a crosslinker and curing agent by reacting with isocyanates or epoxy groups to build polymer network density. In personal care formulations, it neutralises acidic ingredients to adjust pH and acts as a conditioning agent in hair products. It also serves as an antimicrobial buffer in pharmaceutical preparations.
Triethanolamine is available in technical and cosmetic grades and must comply with REACH registration requirements for EU supply. Pharmaceutical applications reference Ph.Eur. monograph standards. It is classified under HS code 29221310 and is typically offered in drums and IBC containers.
