Sodium cocoyl isethionate

Sodium cocoyl isethionate (CAS 61789-32-0), or SCI, is a mild anionic surfactant derived from coconut fatty acids and isethionic acid. Also marketed as Igepon.

Where is Sodium cocoyl isethionate used?

• Solid syndet bars: primary active surfactant, providing dense lather and skin-compatible pH
• Rinse-off personal care: main or co-surfactant in shampoo bars, facial cleansers and body washes
• Home care: dishwashing and light-duty cleaning products where low skin irritation is required
• Cream and lotion cleansers: emulsifying agent
• It delivers effective cleansing with a low irritation profile.

Good to know: Buyers should confirm particle size when sourcing for continuous mixing or spray processes, to match manufacturing equipment and maintain formulation consistency.
