Sulfosuccinates is a type of anionic surfactants. These are mildest among all anionic surfactants. They are chemically classified as dialkyl sulfosuccinates. They can impart a wide variety of functional properties including reduction in surface and interfacial tension, wetting, dispersing, emulsifying, solubilizing, and penetrating. Dioctyl sulfosuccinates (DOSS) have high wetting properties and they are used as industrial cleaning agents. DOSS are synthesized by using maleic anhydride. Dioctyl sulfosuccinates are commercially called docusate, which is in the form of capsule and is used for treating constipation in children.
