  • Microencapsulation process with solvent and salt
    Patent number: 10821080
    Abstract: The present disclosure relates to processes for preparing microparticles using an emulsion process where both a solvent and a salt are used in the continuous phase of the emulsion. The present disclosure also relates to microparticles having an angle of repose of ?35, as measured using a Hele-Shaw cell.
    Type: Grant
    Filed: September 18, 2009
    Date of Patent: November 3, 2020
    Assignee: Evonik Corporation
    Inventors: Adrian Raiche, Jason Campbell, Heather Nettles, Allison Womack
  • Process for preparing microparticles having a low residual solvent volume
    Patent number: 8728528
    Abstract: The disclosed processes for forming microparticles utilize low volumes of processing water while still providing microparticles having low residual solvent levels. The processes are adaptable to both continuous and batch processes using oil/water or water/oil or water/oil/water or oil/water/oil emulsions.
