Disodium Cocoamphodiacetate is a coconut-derived amphoteric surfactant used in cleansers, shampoos, and body washes to provide gentle cleansing, foam, and to reduce the irritation potential of harsher anionic surfactants. It is valued for mildness in baby and sensitive-skin formulations.
| Reported effect | How often | Notes |
|---|---|---|
| Skin or eye irritation | Uncommon | Generally low irritation potential; mild stinging possible at higher concentrations or with eye contact. |
| Allergic contact dermatitis | Rare | Sensitization has been reported, sometimes attributed to manufacturing impurities such as amidoamine or 3-dimethylaminopropylamine. |
| Dryness or transient redness | Rare | More likely in compromised or very sensitive skin with frequent use. |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
