Abstract
There is disclosed a process for preparing compositions 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 microcapsules substantially free of any alkane hardening agent, eliminating potential combustability problems of the prior art processes and toxicity problems of the prior art compositions.
