  • Coprocessed silica coated polymer composition
    Patent number: 10596261
    Abstract: The present invention provides a coprocessed excipient composition and a method of producing the same. The coprocessed excipient comprises vinyl lactam derived polymer and a deagglomerated coprocessing agent. The coprocessing agent is fumed silica, colloidal silica or silicon dioxide. The coprocessed excipient is prepared by a continuous process and has a Brookfield cohesion of less than 0.12 kPa, a bulk density of at least 0.249 gram/milliliter and a flow property as measured by Johanson flow rate number increase from 1.1 to 5.0 fold.
    Type: Grant
    Filed: March 12, 2014
    Date of Patent: March 24, 2020

  • Coprocessed silica coated polymer composition
    Patent number: 10172944
    Abstract: An excipient composition having good bulk density and improved flow characteristics is provided. The present invention particularly provides a coprocessed excipient composition and a method of producing the same. The coprocessed excipient comprises cellulose derived polymer and a deagglomerated coprocessing agent. The coprocessing agent is fumed silica, colloidal silica or silicon dioxide. The coprocessed excipient is prepared in a continuous process and has excellent compactability and improved flow property as measured by Johanson flow rate number increase from 1.1 to 5.0 fold, is characterized by a Brookfield cohesion factor of less than 0.2 kPa and a bulk density of at least 0.249 g/ml.
