Lauramide DEA (diethanolamine) is produced by a condensation reaction at a 1:1 or 1:2 molar ratio of a mixture of lauric and myristic acid to DEA at elevated temperature and in the presence of a catalyst.

It is a mixture of ethanolamides of lauric acid. It is used in cosmetic formulations as a thickener, foam stabilizer, and viscosity builder. It is mainly a non-ionic surfactant, emulsifier, polishing agent used as a thickener and foam improver in shampoos and light detergents. It is also used in hair dyes, bath products, and lotions all frequently contain it. It usually appears as a viscous liquid or a waxy solid.

Safety profile
The Cosmetic Ingredient Review (CIR) Expert Panel has determined that Lauramide DEA is safe to use. It shouldn’t be used in cosmetics and personal care products that contain nitrosating agents in order to avoid the production of potentially cancer-causing nitrosamines. In acute and subchronic studies, lauramide DEA was not found to be a dermal toxin. Lauramide DEA was found to be mild to moderate eye irritants and mild to severe skin irritants.
