Disodium laureth sulfosuccinate

Disodium Laureth Sulfosuccinate (CAS 39354-45-5), also known commercially as alt(70%) and Aerosol A-102, is an anionic surfactant derived from lauryl alcohol ethoxylate and maleic anhydride. It carries a sulfosuccinate head group that provides both anionic charge and mild skin compatibility, distinguishing it from conventional sulfate-based surfactants.

In personal care formulations, it functions as a foam-generating cleansing agent that solubilises sebum and particulate soils while maintaining low irritation profiles suitable for sensitive-skin products. In emulsion polymerisation for coatings and adhesives, it stabilises latex particles electrostatically, reducing coalescence and improving dispersion stability during processing.

Disodium Laureth Sulfosuccinate is supplied under REACH compliance for the European market and is available in liquid form at standard active-matter concentrations. Procurement teams should confirm exact active content and sodium chloride levels with the supplier, as these vary between commercial grades.
