What It Does

Sodium Cocoyl Isethionate is a premium mild anionic surfactant derived from coconut fatty acids and isethionic acid, widely recognized as one of the gentlest cleansing agents available for personal care formulations. It creates a luxurious, creamy lather while maintaining skin's natural moisture barrier, making it the surfactant of choice for sensitive skin products, facial cleansers, and solid syndet bars. Formulators favor SCI for its exceptional mildness combined with effective cleansing power, its ability to form stable solid bars without soap, and its compatibility with a wide pH range, though it typically appears as fine white powder or noodles that require careful processing due to its tendency to form a paste when hydrated.
