Preparation and in vitro evaluation of rosin microcapsules: solvent evaporation technique.
Free flowing, spherical rosin microcapsules were prepared by a method based on phase separation by solvent evaporation. Bentonite was used to prevent the agglomeration and coalescence of the dispersed polymer droplets. The effect of varying the core to coat ratio on micrometric and dissolution properties has been described.
