Applications. Being derived from an ethoxylated intermediate, our sulfosuccinate monoesters carry both a polyoxyethylene chain and an anionic group: they can deliver a double stabilization, the steric one as well as the electrostatic one.
Based on anionic sulfosuccinate chemistry, these surfactants are typically used with sulfide flotation concentrates, iron ore concentrates and coal concentrates and tailings. Care must be taken not to add too much reagent as this can cause water retention and high moisture content. Our Dehscofix DA range of water-soluble dewatering aids reduce
