Triethanolamine (TEA)
Triethanolamine (TEA)
Triethanolamine (TEA) isA colorless to pale yellow viscous liquid with weak alkalinity, it is the hydroxylated product of triethylamine. It is widely used as an emulsifier and pH balancer in cosmetics and detergents, and also in the cement, metal processing, pharmaceutical (e.g., early burn medications) and chemical industries. It is hygroscopic, reacts with acids to form salts, and is listed as a controlled substance under the Chemical Weapons Convention..
Product Details
Physicochemical properties
  • Appearance: Colorless to pale yellow viscous liquid with an ammonia odor; it crystallizes at low temperatures.

  • Solubility: Easily soluble in water, ethanol, acetone, etc., and slightly soluble in non-polar solvents.

  • Alkalinity: Weakly alkaline, it can react with acids to form salts.

  • Hygroscopicity: It easily absorbs moisture and acidic gases (CO2, H2S) from the air.

  • Corrosiveness: Corrosive to copper, aluminum and their alloys. 


Main uses

  • Cosmetics and detergents: Used as an emulsifier, moisturizer, thickener, and pH adjuster in face creams, shampoos, facial cleansers, etc.

  • Cement industry: As a grinding aid, it prevents caking and increases cement yield and early strength.

  • Medicine: Used to treat burns and skin injuries, such as the main ingredient of Biafen, which can promote wound healing.

  • Metal processing: Preparation of corrosion inhibitors to protect metal surfaces.

  • Chemicals: Used as alkalis and catalysts in organic synthesis, or in electroplating and photographic processing.
