Disodium Lauryl Sulfosuccinate
What is Disodium Lauryl Sulfosuccinate?
Disodium Lauryl Sulfosuccinate is an anionic surfactant produced by esterifying lauryl alcohol—often derived from coconut or palm kernel oil—with succinic anhydride, followed by sulfonation and neutralization with sodium hydroxide. This creates a molecule with both hydrophilic sulfate and lipophilic alkyl chain groups. Primarily used in rinse-off personal care products like shampoos, body washes, facial cleansers, and toothpastes, it functions by reducing water's surface tension to enable better spreading and wetting. It forms micelles that trap oils, dirt, and sebum, facilitating their removal during rinsing. Additionally, it generates stable, creamy foam for improved user experience and acts as a hydrotrope to dissolve hydrophobic ingredients like fragrances, preventing phase separation and maintaining product clarity and homogeneity in aqueous formulations. Its mild profile suits daily use.
