CAS No.:



Triethanolamine S is a product from the ethanolamine group, i.e. products of adding ethylene oxide to ammonia. The product is also known as 2,2',2''-Nitrilotriethanol. Triethanolamine S is an oily liquid (at 20 to 25 °C) and solidifies at approximately 15 °C. The product freely soluble in water. 

Triethanolamine is a product with a wide range of industrial applications. Among other things, it is a semi-finished product for chemical synthesis, e.g. for the production of cationic surfactants such as sequestrates. Due to its alkaline character, the product is used to neutralize acidic substances and as a pH-regulating agent. This property is used, among others, in the production of metalworking fluids, detergents and cosmetics. In the latter, it also serves as a wetting and softening agent, e.g. in shaving foams.

Triethanolamine S is also used in the construction industry as a catalyst to accelerate concrete setting. It is also used in the mining industry to remove hydrogen sulphide from natural gas during the so-called sweetening process.

Triethanolamine S is not classified as a dangerous substance.
