Sodium cocoamphoacetate chloroacetate is an extremely mild amphoteric surfactant. Light yellow liquid, 40% solids， is widely used in mild, tear-free shampoos and sensitive skin cleansers due to its commendable surface activity, low irritancy and irritation-relieving properties. Compounding with anionic surfactants significantly improves the dermal compatibility of the final product.
