Sodium lauryl sulfate is an anionic surfactant with strong foaming, emulsifying, and wetting properties.

In pharmaceuticals, it is used at low levels to improve wetting and dissolution of poorly soluble drugs and to modify release profiles.

In personal-care products, it functions as a primary surfactant in shampoos, cleansers, and toothpastes, providing rich foam and effective cleansing.

Formulation requires careful control of concentration and grade to balance performance with skin and mucosal tolerance.
