Lauramidopropyl Betaine is a mild amphoteric surfactant derived from coconut oil, used in cleansers and shampoos to boost foam, cleanse, and reduce the irritancy of harsher anionic surfactants. It also functions as a viscosity enhancer and conditioning agent.
| Reported effect | How often | Notes |
|---|---|---|
| Skin or scalp irritation | Uncommon | Generally well tolerated; mild stinging or redness possible, especially in leave-on or high-concentration use. |
| Eye irritation | Uncommon | Can cause transient stinging if cleanser contacts the eyes. |
| Allergic contact dermatitis | Rare | Sensitization often linked to manufacturing impurities such as dimethylaminopropylamine (DMAPA) or amidoamine rather than the betaine itself. |
