  • METHOD OF MAKING DIALKYL SULFOSUCCINATE COMPOSITIONS
    Publication number: 20180303756
    Abstract: A particulate solid composition comprises a blend of dialkyl sulfosuccinate and a water-soluble polymer. The water-soluble polymer can be a cellulose ether, a polysaccharide, a polyvinyl alcohol homopolymer or copolymer, a polyvinyl pyrrolidone homopolymer or copolymer, a polyvinyl caprolactam polymer or copolymer, a poly(meth)acrylate, a poly(alkylene oxide) graft copolymer, or a combination thereof. The particulate solid composition is free flowing, water-soluble, and dissolves rapidly in water. It can be made by drying a solution of dialkyl sulfosuccinate and a water-soluble polymer. The particulate solid composition can be mixed with organic substances having low water solubility, for example a generic, a biologic, a biosimilar, an excipient, a nutraceutical, a medical diagnostic agent, an agricultural chemical, or a combination thereof, to form water-soluble compositions.
    Type: Application
