PPG-2 COCAMIDE.

Valuable / SURFACTANT - CLEANSING, VISCOSITY CONTROLLING

PPG-2 Cocamide is a synthetic polyether derived from coconut fatty acids, primarily functioning as a versatile surfactant and emulsifier. It enhances product texture and stability by reducing surface tension, allowing for the stable combination of oil and water phases. This ingredient also contributes to improved foam quality and viscosity control in formulations.

Science

Mechanism of Action

As a surface-active agent, PPG-2 Cocamide operates by significantly lowering the interfacial tension between immiscible liquids, thereby enabling the formation and stabilization of emulsions, such as oil-in-water systems. In cleansing products, it effectively solubilizes and removes impurities while boosting lather quality. Furthermore, it acts as a viscosity controlling agent, contributing to the desired rheology and luxurious feel of cosmetic formulations.
