Sodium Lauryl Sulfate (SLS) is an anionic surfactant.
Description
Sodium Lauryl Sulfate, or Sodium dodecyl sulfate, lowers the surface tension of aqueous solutions and is popular due to its ability to properly disperse the ingredients.

It is often applied in personal care, cosmetics, and pharmaceutical industries. SLS is broadly added to various cleaning and washing products.
SLS can be used in the production of shampoos, rinses, conditioners, lotions, creams, and toothpaste. In domestic detergent applications and home cleaning products (such as laundry detergents, dishwashing products, and soaps, bathroom detergents, window, and glass cleaning products).
