Sodium Lauryl Sulfate (SLS)

Sodium lauryl sulfate (SLS) is an anionic surfactant and sodium-based compound widely used for its foaming, emulsifying, and cleaning properties. It is a key ingredient in detergents, soaps, shampoos, toothpastes, and household cleaning products, where it provides excellent lather and effective removal of oils, dirt, and residues. In industrial applications, SLS functions as a wetting agent, dispersant, and emulsifier, supporting chemical manufacturing and processing operations.

Beyond detergents and cleaning, sodium lauryl sulfate is applied in textiles, paper processing, and leather treatment, where its surface activity enhances efficiency. It is also used in personal care and cosmetic formulations, pharmaceuticals, and laboratory research as a standard reagent in protein analysis (SDS-PAGE). With its versatility, cost-effectiveness, and reliable performance, SLS remains one of the most widely used surfactants, serving industries from consumer goods and healthcare to textiles, water treatment, and specialty chemicals.
