---------------------------------------------------------------

Sodium bis(2-ethylhexyl) sulfosuccinate (C₂₀H₃₇NaO₇S), often referred to as docusate sodium, Aerosol OT or AOT, is an anionic surfactant and a common ingredient in consumer products, especially laxatives of the stool softener type. AOT is the most widely used surfactant in reverse micelle encapsulation studies It is also a component of the oil dispersant Corexit.
