Cocamide MEA (Cocamide monoethanolamide) is a coconut oil-derived non-ionic surfactant used in cleansers and shampoos as a foam booster, viscosity enhancer, and emulsion stabilizer. It is a formulation/base ingredient rather than a treatment active.
| Reported effect | How often | Notes |
|---|---|---|
| Skin irritation | Uncommon | Mild irritation possible, generally with prolonged or high-concentration exposure. |
| Allergic contact dermatitis | Rare | Sensitization reported in some patch-test studies, particularly in those with surfactant sensitivity. |
| Eye irritation | Uncommon | Can occur with rinse-off products contacting the eyes. |
| Nitrosamine contamination concern | Very rare | Theoretical risk if formulated with nitrosating agents; ethanolamides can form nitrosamines under certain conditions. |
