Sodium lauroyl isethionate

Sodium lauroyl isethionate (CAS 7381-01-3, EC 230-949-8) is an anionic surfactant derived from isethionic acid and lauric acid. It is commercially known under trade names including Igepon A and has been catalogued as CCRIS 528. No E-code designation applies to this substance.

In personal care formulations, it functions as a mild cleansing and emulsifying agent by reducing interfacial tension between oil and water phases, enabling stable lather with low skin irritation potential. In coatings and adhesive systems, it supports pigment and filler dispersion by adsorbing onto particle surfaces and preventing reagglomeration.

Sodium lauroyl isethionate is supplied in compliance with REACH registration requirements applicable to the European market. Procurement teams should confirm available grades, as purity specifications vary by intended application. Standard packaging formats for industrial supply typically include drums and IBCs; buyers are advised to request current technical data sheets and safety documentation from their supplier.
