Disodium Cocoamphodiacetate is an amphoteric surfactant derived from coconut oil, recognized for its gentle yet effective cleansing and conditioning properties. It aids in removing impurities while helping to maintain the skin's natural moisture balance and pH levels. This versatile ingredient enhances foam and contributes to product stability across a wide pH range.

Science

Mechanism of Action

This ingredient functions by reducing surface tension, which facilitates the mixing of water with oils and dirt, allowing them to be rinsed away from skin and hair. It acts as a mild foaming agent and a foam booster, significantly improving the volume, texture, and stability of lather. Additionally, it conditions the skin by helping to preserve its natural moisture barrier and pH, and functions as an emollient in hair products, enhancing body, suppleness, and sheen in dry or damaged hair.
