Sodium laureth-12 sulfate is an anionic surfactant derived from lauryl alcohol that has been ethoxylated and then sulfated. It is widely used in personal care, household, and industrial formulations for its strong cleansing, foaming, and emulsifying properties. This ingredient is especially valued in shampoos, body washes, liquid soaps, and cleaning products where effective soil and oil removal is required. Its balance of performance and mildness makes it a preferred surfactant in a variety of applications.
