  • Process for preparation of microspheres
    Patent number: 4933105
    Abstract: Microspheres, prepared by solvent removal from an oil-in-water emulsion using carboxylic acid salt surfactant, e.g., sodium oleate as the emulsifier.
    Type: Grant

  • Process for preparation of microspheres and modification of release rate of core material
    Patent number: 4479911
    Abstract: This invention provides for the production of microspheres in an oil-in-water emulsion process using an emulsifier, whereby solvent removal from the oil phase allows for isolation of discrete microspheres, wherein the release rate of a core material is modified by the use of an alkaline agent, e.g. sodium hydroxide, during the preparation of the microspheres.
