IMPROVED PHASE SEPARATION MICROENCAPSULATION PROCESS AND PHARMACEUTICAL COMPOSITIONS PRODUCED THEREBY ABSTRACT There is disclosed a process for preparing compo- sitions comprising microcapsules by phase separation microencapsulation wherein the hardening agent employed is a volatile silicone fluid and with the compositions prepared thereby. The use of the volatile silicone fluid as a hardening agent permits the production of micro- capsules substantially free of any alkane hardening agent, eliminating potential combustability problems of the prior art processes and toxicity problems of the prior art compositions.
