Disodium 4-lauryl sulfosuccinate

Disodium 4-lauryl sulfosuccinate (CAS 13192-12-6) is an anionic surfactant derived from sulfosuccinic acid, used across personal care and industrial processing for its foam-modifying, emulsifying, and cleaning performance. It functions as a mild but effective surface-active agent suited to formulations where skin compatibility and process efficiency are both priorities. In personal care, it appears in shampoos, body washes, and facial cleansers.

These applications require controlled foam and mild cleansing without aggressive stripping of the skin barrier. Textile wet processing relies on it as an emulsifier and wetting agent during dyeing and finishing operations. This improves liquor penetration and dye uptake uniformity across various fabric types. In leather processing, it supports degreasing and preparation steps where consistent emulsification of fats and oils is critical to hide quality.

Paper manufacturing uses it as a dispersing and foaming-control agent in pulp treatment and coating formulations. This versatility makes it a staple ingredient for manufacturers seeking reliable performance in aqueous systems. Disodium 4-lauryl sulfosuccinate is typically supplied as an aqueous solution, with active content concentrations commonly ranging around 30–40%. Both technical-grade and cosmetic-grade specifications are available.

These options meet the differing purity requirements of industrial and personal care buyers. The material is handled according to standard chemical safety protocols to ensure stability and efficacy in final commercial products.
