Sodium methyl isethionate

Sodium methyl isethionate (CAS 869737-84-8), also marketed as SURFONIC SMI, is a mild sulfonate-based surfactant used primarily in personal care and cleaning formulations. It delivers effective cleansing and emulsification while maintaining compatibility with sensitive skin applications.

In personal care, it functions as a primary or co-surfactant in shampoos, body washes, and facial cleansers where mildness and foam quality are formulation priorities. This versatile ingredient integrates seamlessly with other surfactant systems.

Home care and industrial cleaning products use it to boost degreasing performance and improve soil dispersion on hard surfaces. Its chemical stability makes it a reliable choice for a wide variety of household and commercial detergents.

Textile processing operations incorporate it to aid fiber wetting and uniform dye distribution during treatment stages. This ensures high-quality finishes and consistent results across different types of natural and synthetic fabrics.

Paper and leather manufacturing also draw on its dispersing properties to support consistent surface treatment and processing aid applications. It helps maintain the integrity of materials while facilitating efficient production cycles.

Sodium methyl isethionate is typically supplied as an aqueous solution, with concentration levels suited to direct incorporation into liquid formulation processes. This format allows for easy handling and precise dosing in large-scale manufacturing.

Technical grade is the standard commercial offering, with supply specifications aligned to surfactant industry requirements. Packaging options generally range from drums to IBC totes for bulk procurement to meet diverse industrial needs.
