GlossarySodium Dodecyl Sulfate (SLS)

synthetic detergent and surfactant used in shampoos and cleaning products

Sodium Dodecyl Sulfate (SDS), also known as Sodium Lauryl Sulfate (SLS), is a synthetic detergent and surfactant commonly used in cleaning products, shampoos, and toothpaste. It works by lowering the surface tension of water, allowing it to more effectively remove oils and dirt. In scientific research, SDS is also used in protein denaturation during SDS-PAGE, a technique for separating proteins based on their molecular weight.
