What is Cocamidopropyl DEA? Cocamidopropyl DEA is a common cosmetic ingredient used in skincare products. It aids these products in their effectiveness and keeps our skin clean and healthy.”
But cocamidopropyl DEA is a surfactant. This means it assists in cleaning our skin by removing the dirt as well as fats. It can appear in products such as cleansers, shampoos and body washes. It creates foam and allows the product to spread out over our skin or hair.
Cocamidopropyl DEA is OK for cleansing our skin but it may cause skin irritation or allergies in some people. Pay attention to how your skin feels being around these products. If you are irritated by something, stop using it.

Cocamidopropyl DEA may be called by its full name or as CAP-DEA on ingredient labels. If you are concerned about using products containing this ingredient, read labels carefully and consider opting for products that do not contain cocamidopropyl DEA.

Cocamidopropyl DEA is controversial because some studies suggest it may be harmful to health. It’s considered safe in small amounts, according to the F.D.A., but some people prefer to stay away from it just in case.

But if you’d prefer to avoid products with cocamidopropyl DEA, there are other ingredients that can be equally effective at cleaning. Seek products that contain coconut oil, aloe vera or glycerin. They are mild on the skin and generally well tolerated by most people.
