摘要：
The method disclosed herein comprises using a non-polar alkane in the continuous phase of an emulsion process to aid in the removal of dispersed phase solvent from the microparticles. The microparticles can further be subjected to a post-production treatment process, involving a non-polar alkane suspension and a rinse, to further reduce residual dispersed phase solvent levels.
