Cocamidopropyl Hydroxysultaine is a mild amphoteric surfactant derived from coconut fatty acids, used in cleansers, shampoos, and body washes to provide gentle foaming, cleansing, and foam-boosting properties. It is often combined with primary surfactants to reduce overall irritancy.
| Reported effect | How often | Notes |
|---|---|---|
Skin or eye irritation | Uncommon | Generally mild; more likely at higher concentrations or in leave-on or sensitive-eye applications. |
Allergic contact dermatitis | Rare | Sensitization is often attributed to manufacturing impurities such as amidoamine or dimethylaminopropylamine rather than the surfactant itself; cross-reactivity with cocamidopropyl betaine is reported. |
Mucosal or scalp stinging | Rare | Transient and typically resolves on rinsing. |
