Cocamide DEA

Lauramide DEA, the major component of cocamide DEA

Cocamide DEA, or cocamide diethanolamine, is a diethanolamide made by reacting the mixture of fatty acids from coconut oils with diethanolamine.^[1] It is a viscous liquid and is used as a foaming agent in bath products like shampoos and hand soaps, and in cosmetics as an emulsifying agent. See cocamide for the discussion of the lengths of carbon chains in the molecules in the mixture. The chemical formula is CH₃(CH₂)_nC(=O)N(CH₂CH₂OH)₂, where n can vary depending on the source of fatty acids.

Safety

Cocamide DEA is an allergen that may cause contact dermatitis in individuals who are susceptible to skin allergies.^[2] Cocamide DEA showed a high irritation potential.^[3]
