TEA-Dodecylbenzenesulfonate is an anionic surfactant (the triethanolamine salt of dodecylbenzenesulfonic acid) used as a cleansing and emulsifying agent in rinse-off and some leave-on cosmetic formulations. It helps remove dirt and oil and contributes to foaming.
| Reported effect | How often | Notes |
|---|---|---|
| Skin irritation | Common | Anionic surfactants can cause dryness, stinging or irritation, especially with high concentration or prolonged contact. |
| Eye irritation | Common | May cause stinging or redness on direct contact with eyes. |
| Contact dermatitis | Uncommon | Allergic or irritant dermatitis reported in sensitive individuals. |
| Nitrosamine formation concern | Rare | TEA-based ingredients can theoretically form nitrosamines if combined with nitrosating agents; a formulation/safety consideration rather than a direct user reaction. |
