Disodium lauryl sulfosuccinate

Disodium Lauryl Sulfosuccinate (CAS 13192-12-6), also known by the abbreviation LDSS or the common name Dodecyl sodium sulfosuccinate, is an anionic surfactant derived from lauryl alcohol and maleic anhydride. It carries no assigned E-code and is distinct from related sulfosuccinate esters used in food applications.

In personal care formulations, LDSS functions as a mild foaming and cleansing agent by reducing interfacial tension between oils and water, making it suitable for low-irritation shampoos and body washes. In textile and leather processing, it supports emulsification of treatment baths and assists in uniform dye penetration by dispersing hydrophobic substrates.

Disodium Lauryl Sulfosuccinate is supplied in compliance with REACH regulations and is available for procurement in standard industrial packaging. Buyers should confirm grade specifications, including active matter content and sodium sulfate levels, directly with the supplier to match formulation requirements.
