APPLICATION:
Triethanolamine is used primarily as an emulsifier and surfactant. It is a common ingredient in formulations used for both industrial and consumer products. The triethanolamine neutralizes fatty acids, adjusts and buffers the pH, and solubilises oils and other ingredients that are not completely soluble in water. Some common products in which triethanolamine is found are liquid laundry detergents, dishwashing liquids, general cleaners, hand cleaners, polishes, metalworking fluids, paints and printing inks.
Cement production
Triethanolamine is also used as organic additive (0.1 wt. %) in the grinding of cement clinker. It facilitates the grinding process by preventing agglomeration and coating of the powder at the surface of balls and mill wall.
Cosmetics and medicine
Various ear diseases and infections are treated with eardrops containing triethanolamine polypeptide oleate-condensate, such as Cerumenex in the United States. In pharmaceutics, triethanolamine is the active ingredient of some ear drops used to treat impacted earwax. It also serves as a pH balancer in many different cosmetic products – ranging from cleansing creams and milks, skin lotions, eye gels, moisturizers, shampoos, shaving foams etc. TEA is a fairly strong base: a 1% solution has a pH of approximately 10, whereas the pH of skin is below pH 7. Cleansing milk/cream emulsions based on TEA are particularly good at removing makeup. Because of its high alkalinity and the possibility that it converts to nitrosamines (carcinogenic compounds), its use in cosmetics was once expected to diminish. It is still widely used as of 2009.
In the laboratory and in amateur photography
Another common use of TEA is as a complexing agent for aluminium ions in aqueous solutions. This reaction is often used to mask such ions before complexometric titrations with another chelating agent such as EDTA. TEA has also been used in photographic (silver halide) processing. It has been promoted as a useful alkali by amateur photographers.
In Electroless Plating
TEA is now commonly and very effectively used as a complexing agent in Electroless Plating.
