Disodium laureth sulfosuccinate

Disodium Laureth Sulfosuccinate (CAS 40754-59-4, EC 255-062-3) is an anionic surfactant derived from lauryl alcohol ethoxylate and maleic anhydride, classified under the sulfosuccinate family. It is commercially available under trade names including MES 403 and MES-30 AEMES, and carries no assigned E-code. Its molecular formula is C22H42O10S.2Na.

In personal care formulations, it functions as a mild emulsifier and foam-generating agent, reducing interfacial tension between oil and water phases while maintaining low skin irritation profiles. In textile processing, it acts as a dispersant and cleaning agent, penetrating fiber surfaces to remove oils and sizing agents. Coatings and adhesive manufacturers use it to stabilize emulsion polymerization systems.

This material is supplied in compliance with REACH regulations and is available for procurement across European markets. Standard commercial grades are offered in liquid form at varying active matter concentrations, typically 30 to 40 percent. Buyers should confirm grade specifications and packaging formats directly with the supplier.
