Diethanolamine, nke a na-akpọkarị DEA ma ọ bụ DEOA, bụ ngwakọta organic nwere usoro HN (CH2CH2OH) 2. Diethanolamine dị ọcha bụ ihe siri ike na-acha ọcha na ụlọ okpomọkụ, mana ọchịchọ ya ịmịkọrọ mmiri na nke dị mma nke pụtara na a na-ezutekarị ya dị ka mmiri na-enweghị agba, viscous. Diethanolamine bụ polyfunctional, ịbụ amine nke abụọ na diol. Dị ka amines organic ndị ọzọ, diethanolamine na-arụ ọrụ dị ka isi adịghị ike. Na-egosipụta àgwà hydrophilic nke amine nke abụọ na ìgwè hydroxyl, DEA na-agbaze na mmiri. Amides kwadebere site na DEA na-abụkarị hydrophilic. N'afọ 2013, ụlọ ọrụ International Agency for Research on Cancer kewapụtara kemịkal ahụ dị ka "ikekwe carcinogenic nye mmadụ".
