What is Disodium laureth sulfosuccinate?
Disodium laureth sulfosuccinate (CAS 39354-45-5) is a mild anionic surfactant used in personal care and industrial formulations for foaming, cleansing, and emulsifying performance.
Where is Disodium laureth sulfosuccinate used?
- Personal care: primary or co-surfactant in shampoos, body washes, and baby care products
- Cleansing systems: builds stable, dense foam while reducing harshness of sulfate-based surfactants
- Textile and leather processing: wetting and emulsification during scouring and dyeing
- Coatings and adhesives: dispersing and emulsifying agent in aqueous systems
- It combines low irritation potential with effective surface activity.
Commercial specifications
- Active matter concentrations commonly ranging between 30 percent and 40 percent
- Packaging options generally include drums and IBCs for bulk procurement
