Diethanolamine (DEA) belongs to the category of the ethanolamines and is used primarily in the manufacture of agrochemicals, but it also finds application in the production of cleaning agents and detergents.

Diethanolamine is obtained from the reaction of Ethylene Oxide and Ammonia. This reaction also produces Monoethanolamine and Triethanolamine, which are also products sold by Saiper.

Ethanolamines are chemical compounds belonging to the group of amines and alcohols. This results in their unique property of being able to react with both groups: in the form of alcohol, ethanolamines are hygroscopic and can react to form esters, whereas in the form of amines, they are slightly alkaline and react with acids to salts and soaps. These properties form the basis for most applications of Diethanolamine.

For industrial applications, DEA is used either in pure form (concentration >99%) or as an aequeous solution of varying concentrations.

Saiper only markets the pure product of >99% purity.
