Science

Functioning as a highly effective surfactant, Sodium Cocoate significantly lowers the surface tension of water, facilitating the seamless integration of oil and water phases. This action allows for the efficient encapsulation of oils, dirt, and sebum within stable micelles, enabling their thorough removal from the skin. Concurrently, it enhances the tactile experience by promoting a rich, consistent lather during application.
