Sodium Cocoamphodiacetate
What is Sodium Cocoamphodiacetate?
Sodium Cocoamphodiacetate is an amphoteric surfactant derived from coconut oil fatty acids reacted with diacetic acid, resulting in a molecule with both positive and negative charges that adjust based on pH. This structure provides mild cleansing properties ideal for rinse-off personal care products like shampoos, body washes, facial cleansers, and baby products. It functions by reducing surface tension between water and oils, effectively lifting dirt, sebum, and residues from skin and hair surfaces while generating stable foam. Its balanced charge minimizes disruption to the skin's natural barrier compared to harsher surfactants, supporting formulation of gentle, non-stripping cleansers. Often used at low levels, it also aids in emulsifying oils and improving product texture for better user experience.
