Sodium Cocoyl Isethionate (Sodium Cocoyl Isethionate)

Sodium Cocoyl Isethionate is a mild anionic surfactant derived from fatty acids and isethionic acid, widely valued in cosmetic formulations for gentle yet effective cleansing and a rich, creamy foam profile. It helps remove oils and impurities while supporting a softer, less-stripping after-feel compared with many traditional sulfate surfactants, making it a popular choice for sensitive-skin and “syndet” (soap-free) concepts. Sodium Cocoyl Isethionate also contributes to improved sensorial creaminess and can enhance mildness when blended with amphoteric or non-ionic co-surfactants. It is commonly used in solid cleansing bars and facial bars, body washes, cleansers, shampoos, and foaming bath products, particularly in formulations designed to deliver dense lather and good rinse-off comfort. Use level and performance are formulation-dependent and typically optimized with the broader surfactant system, pH strategy, and processing conditions to achieve the desired foam, hardness (in bars), and overall stability.
