Sodium oleoyl isethionate

Sodium oleoyl isethionate (CAS 142-15-4), also known as sodium 2-sulphonatoethyl oleate, is an oleic acid-derived isethionate surfactant used in personal care and cleaning formulations.

It functions as a mild anionic surfactant, delivering cleansing, emulsification, and foam modulation across a range of finished products. In skin cleansing bars and syndet formulations, it contributes gentle lather.

This surfactant offers reduced irritation potential compared to conventional soap bases, which is a key consideration for sensitive skin product lines. Body washes and facial cleansers incorporate it to emulsify sebum.

The material effectively removes rinse-off residues while maintaining skin feel. In home care and industrial cleaning concentrates, it supports degreasing performance and dispersion of oils in aqueous systems.

Shampoo and conditioning cleanser formulators also use it to balance foam profile and improve compatibility with co-surfactant blends. It is typically supplied as a paste or liquid for easy handling.

Concentration and carrier composition vary by manufacturer. Cosmetic-grade material is the standard commercial form, with technical-grade variants available for industrial cleaning applications.

Buyers should confirm active matter content and sodium chloride levels when evaluating grades for formulation fit. This ensures the material meets the necessary performance requirements for specific end-use applications.
