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.

Where is Sodium oleoyl isethionate used?

• Skin cleansing bars and syndet formulations: gentle lather
• Body washes and facial cleansers: emulsify sebum
• Shampoo and conditioning cleansers: balance foam profile and improve compatibility with co-surfactant blends
• Home care and industrial cleaning concentrates: degreasing and dispersion of oils in aqueous systems
• It functions as a mild anionic surfactant for cleansing, emulsification and foam modulation.

Good to know: Reduced irritation potential compared to conventional soap bases, a key consideration for sensitive skin lines. Buyers should confirm active matter content and sodium chloride levels for formulation fit.
