The Ordinary’s Sulphate 4% Cleanser for Body and Hair contains SLES-2, a milder anionic surfactant and foaming agent, that creates a satisfying lather while cleansing efficiently.Designed using a minimalistic formulation approach, the cleanser maintains a sensorial effect while incorporating the gentler attributes of SLES-2 at 4%. Gentler than SLS, this mild-natured cleansing agent is ideal for all-over use on body and hair.
