General description

Triethanolamine (TEA) belongs to the family of ethanolamine. It includes the properties of both amines and alcohols.[1] Addition of TEA to an acidic buffer facilitates the determination of fluoride in inorganic orthophosphates by using a fluoride-selective electrode.[2]

Application

Triethanolamine hydrochloride has been used:
  • in the preparation of triethanolamine buffer[3]
  • in rinsing the digested sections, prepared for in situ hybridization[4]
  • as a component of solution A to prepare TA-complement haemolysis buffer (TA-CHB)[5]

Biochem/physiol Actions

Triethanolamine hydrochloride acts as a surfactant or pH adjuster.[6] It is also used as an emulsifier in cosmetics and several topical medications.[7]
