The Uses of Sodium Lauryl Sulfate
sodium lauryl sulfate is a base surfactant, foaming agent with good foaming properties, dispersant, and wetting agent. Formulators have found it ideal for designing cleansers and soaps packaged with pump dispensers. However, it is considered among the most irritating surfactants associated with skin dryness and redness. often, it is either replaced by less irritating but related surfactants such as sodium laureth sulfate, or anti-irritant ingredients are incorporated into the formulation together with the sodium lauryl sulfate in order to reduce sensitivity potential.
