Cocamidopropyl Dimethylamine
A hair-conditioning, static-cutting ingredient made from coconut fatty acids.
What it does
It’s made from coconut fatty acids. In a slightly acidic product it carries a positive charge, so it clings to hair, softening it and cutting static.
The EU’s ingredient database lists it as an emulsifier (helps oil and water mix).European Commission, CosIng (© European Union, CC BY 4.0) · uses put in plain words by Drop ↗
The evidence, graded
expert consensusUS safety reviewers (2019) assessed 24 amidoamines, used mostly to cut static, and cocamidopropyl dimethylamine is named in their conclusion. Data show they may cause skin allergy, partly from a leftover called DMAPA. They judged them safe in products made not to cause allergy, and said they shouldn’t go in formulas with N-nitrosating agents. Cocamidopropyl dimethylamine can also be a leftover in the cleanser cocamidopropyl betaine.Burnett 2019 · International Journal of Toxicology ↗
