Sodium Cocoyl Isethionate – Benefits, Side Effects & Uses

by ThankMeNow Editors on Sep 10, 2025
Sodium Cocoyl Isethionate (SCI) is famously nicknamed "Baby Foam" because of its extraordinary mildness—so gentle that it’s a standard in infant care and ultra-sensitive facial routines. Derived from the fatty acids of coconut oil, SCI is a high-performance surfactant that creates a rich, dense, and luxurious lather without the skin-stripping alkalinity of traditional soaps. Its unique molecular structure allows it to effectively solubilize oil and sunscreen while leaving the skin’s structural proteins and essential moisture barrier intact. In your routine, SCI ensures that your "clean" never feels "tight," providing a supple, velvet-like finish that perfectly preps the skin for high-potency serums and treatments.
