Disodium laureth sulfosuccinate

Disodium laureth sulfosuccinate (CAS 36409-57-1) is a mild anionic surfactant used across personal care and industrial cleaning formulations. It delivers effective foaming and emulsification.

It provides detergency while maintaining a gentler profile than conventional sulfate-based surfactants. This is a key consideration for sensitive-skin and low-irritation product lines in the market.

In personal care, it functions as a primary or co-surfactant in shampoos, body washes, and baby cleansers. This is where foam quality and mildness must be balanced simultaneously for the user.

Textile processors use it as a scouring and wetting agent to remove oils, sizing agents, and process soils. It works on fiber substrates without damaging delicate materials during the cycle.

In leather processing, it supports degreasing baths during pre-tanning stages, helping achieve consistent surface preparation. This ensures the material is ready for subsequent treatment steps.

Paper manufacturers incorporate it into pulp processing and coating formulations to control foam. It also helps to improve the dispersion of fiber slurries throughout the manufacturing process.

The chemical is typically supplied as an aqueous solution, with active content concentrations commonly ranging from 30% to 40%. Both cosmetic-grade and technical-grade material are available.

Cosmetic-grade material is commonly evaluated against standard purity and safety benchmarks. These are relevant to both rinse-off and leave-on formulations for various consumer applications.
