PPG-2 Hydroxyethyl Cocamide is a nonionic surfactant and foam booster widely used in personal care formulations. It enhances foam stability, thickens formulations, and improves mildness for skin and hair. Derived from coconut fatty acids, it is compatible with other anionic and amphoteric surfactants. Commonly found in shampoos, body washes, and facial cleansers, it provides gentle cleansing while maintaining product texture and performance.
