Sodium cocoyl isethionate

Sodium cocoyl isethionate (CAS 61789-32-0), commonly abbreviated as SCI, is a mild anionic surfactant derived from coconut fatty acids and isethionic acid. It delivers effective cleansing with a notably low irritation profile.

This ingredient is a preferred choice for formulators targeting sensitive skin applications. Igepon is a recognized trade name under which this ingredient has historically been supplied to the global market.

SCI is the primary active surfactant in solid syndet bars, which are synthetic detergent bars formulated without traditional soap. In these applications, it provides dense lather and a skin-compatible pH.

In rinse-off personal care products such as shampoo bars, facial cleansers, and body washes, it functions as the main or co-surfactant. It is valued for its ability to deliver foam volume and mildness simultaneously.

Home care formulators incorporate it into dishwashing and light-duty cleaning products where low irritation to skin contact is a requirement. It also acts as an emulsifying agent in cream and lotion cleansers.

Sodium cocoyl isethionate is supplied primarily as a white to off-white powder or compressed flake form. Flakes are often the preferred format for solid bar manufacturing due to their handling characteristics.

Standard commercial grades include cosmetic-grade and personal care-grade material meeting typical industry purity benchmarks. Active matter content is commonly specified at 84–90% for most industrial applications.

Buyers should confirm particle size when sourcing for continuous mixing or spray processes. This ensures compatibility with specific manufacturing equipment and maintains consistency in the final product formulation.
