Product Safety Assessment-DOW¢â Triethanolamine

http://www.cosmeticsinfo.org/
Triethanolamine is listed as Trialkylamines, trialkanolamines and their salts, and Ethanolamine is listed as Monoalkylamines, monoalkanolamines and their salts, in Annex III, Part I (substances which cosmetic products must not contain except subject to the restrictions and conditions laid down) of the Cosmetics Directive of the European Union. Triethanolamine may be used in non-rinse-off and other cosmetics and personal care products at a maximum concentration of 2.5%. Ethanolamine can be used in cosmetics and personal care products if the secondary amine is less than or equal to 0.5%. Neither Triethanolamine nor Ethanolamine can be used with nitrosating systems, they must have purity of 99% with a maximum secondary amine content of 0.5%, and a nitrosamine content of 50 microg/kg or less, and the products must be in nitrite-free containiers.

Local:
There are three ethanolamines called mono, di and tri-ethanolamine with formula (CH2CH2OH)NH2, (CH2CH2OH)2NH, and (CH2CH2OH)3N respectively. They are hygroscopic viscous liquid or semi-solid at room temperature. They are soluble in water, in alcohol and acetone, insoluble in ether and benzene;

They are corrosive with a characteristic ammonia-like odor. their colors range from almost colorless to amber depending on purity. These substances decompose on heating and produce toxic and corrosive gases including nitrogen oxides. They are medium strongly basic and react with cellulose nitrate resulting in causing fire and explosion hazard. They react violently with strong acids and strong oxidants. Ethanolamines are produced from ethylene oxide reacted with ammonia. The principle product is monoethanolamine and secondary products of diethanolamine and triethanolamine are produced since ethylene oxide is reactive.  They are the simplest members of the alkanolamine compounds. They have the physical and chemical characteristics of both alcohols and amines in one molecule. Ethanolamines stuctures are widely found in antihistamine drugs. In industrial field, monoethanolamine is an important raw material in the production of ethylenediamine. Ethanolamines are used as gas-scrubber in refinery and natural gas operations. They are widely used in the field of:

  • Gas-scrubber
    • Natural and refinery gas operations
    • Hydrogen sulfide (H2S) and CO2 gas removal
  • Textile Operation
    • Softeners
    • Lubricants
    • Dye Leveling Agents
    • Dispersants
    • Durable Press
    • Optical Brighteners
  • Surfactants and  Metalworking fluids
    • Impart alkalinity
    • Detergents
    • Cosmetic formulations
    • Acid neutralization
    • Fatty acid soaps
