Triethanolamine 99%, or TEA is a viscous organic compound that is both a tertiary amine and a triol. A triol is a molecule with three alcohol groups. Approximately 150,000 tonnes were produced in 1999. Triethanolamine 90% is a colourless compound although samples may appear yellow because of impurities.

Production Triethanolamine 99% is produced from the reaction of ethylene oxide with aqueous ammonia, also produced are ethanolamine and diethanolamine. The ratio of the products can be controlled by changing the stoichiometry of the reactants.

Applications Triethanolamine 99% is used primarily in making surfactants, such as for emulsifier. Triethanolamine 99% is a common ingredient in formulations used for both industrial and consumer products. The triethanolamine neutralizes fatty acids, adjusts and buffers the pH, and solubilizes oils and other ingredients that are not completely soluble in water. Triethanolammonium salts in some cases are more soluble than salts of alkali metals that might be used otherwise, and results in less alkaline products than would from using alkali metal hydroxides to form the salt. Some common products in which triethanolamine is found are sunscreen lotions, liquid laundry detergents, dishwashing liquids, general cleaners, hand sanitizers, polishes, metalworking fluids, paints, shaving cream and printing inks.[5]

Cement production Triethanolamine 99% is also used as organic additive (0.1 wt%) in the grinding of cement clinker.Triethanolamine 99% facilitates the grinding process by preventing agglomeration and coating of the powder at the surface of balls and mill wall.[6]
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 eardrops used to treat impacted earwax. Triethanolamine 90% 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, and so on. Triethanolamine 90% is a fairly strong base: a 1% solution has a pH of approximately 10, whereas the pH of skin is less than pH 7, approximately 5.5-6.0. Cleansing milk-cream emulsions based on Triethanolamine 90% are particularly good at removing makeup.
Derivatives
Amustaline
Trolnitrate
Trimustine
Another common use of Triethanolamine 90% 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. Triethanolamine 90% has also been used in photographic (silver halide) processing. Triethanolamine 90% has been promoted as a useful alkali by amateur photographers.
 
In holography
Triethanolamine 99% is used to provide a sensitivity boost to silver-halide-based holograms, and also as a swelling agent to color shift holograms. It is possible to get the sensitivity boost without color shift by rinsing out the TEA before squeegee and drying.[7]

In electroless plating
Triethanolamine 99% is now commonly and very effectively used as a complexing agent in electroless plating.
 
In ultrasonic testing
2-3% in water Triethanolamine 90% is used as an corrosion inhibitor (anti-rust) agent in immersion ultrasonic testing.
 
In aluminium solderingTriethanolamine 99%, diethanolamine and aminoethylethanolamine are major components of common liquid organic fluxes for the soldering of aluminium alloys using tin-zinc and other tin or lead-based soft solders.[8][9][10]

Safety and regulation
Allergic reactions
A 1996 study found that Triethanolamine 99% (TEOA) occasionally causes contact allergy. A 2001 study found Triethanolamine 99% in a sunscreen caused an allergic contact dermatitis.[12] A 2007 study found Triethanolamine 90% in ear drops caused a contact allergy.[13] Systemic and respiratory tract (RT) toxicity was analyzed for 28 days in a nose specific inhalation 2008 study in Wistar rats;Triethanolamine 90% seems to be less potent in regard to systemic toxicity and RT irritancy than diethanolamine (DEA). Exposure to Triethanolamine 90% resulted in focal inflammation, starting in single male animals from 20 mg/m3 concentrations.[14]
 
A 2009 study stated that patch test reactions reveal a slight irritant potential instead of a true allergic response in several cases, and also indicated the risk of skin sensitization to Triethanolamine 90% seems to be very low.[15]

Tumors
Reports indicated that Triethanolamine 99% causes an increased incidence of tumor growth in the liver in female B6C3F1 mice, but not in male mice or in Fischer 344 rats.[16] A 2004 study concluded "Triethanolamine 90% may cause liver tumors in mice via a choline-depletion mode of action and that this effect is likely caused by the inhibition of choline uptake by cells."[16]
 
Environmental toxicity
A 2009 study found that Triethanolamine 90% has potential acute, sub-chronic and chronic toxicity properties in respect to aquatic species.
 
Regulation
Triethanolamine 99% is listed part B of the Chemical Weapons Convention as Triethanolamine 90% can be used in the manufacture of HN3 nitrogen mustard.

Description
General description Triethanolamine 99% (TEA) belongs to the family of ethanolamine. It includes the properties of both amines and alcohols. Addition of TEA to an acidic buffer facilitates the determination of fluoride in inorganic orthophosphates by using a fluoride-selective electrode.
 
ApplicationTriethanolamine 99% (TEA) has been used:
• as a component of the acetylation working solution
• in the preparation of polyethylene glycol (PEG) hydrogels
• as a constituent of CO2/O2 specificity (SC/O) assay buffer
 
Description: Organic compound composed of a tri-alcohol & an amine. Triethanolamine 99% is a weak base (pH 10-11), widely used to elevate the pH in cosmetic formulas.
