This method avoids the use of the organic solvents used in some traditional microencapsulation processes, not only eliminating any problems associated with the presence of residual solvent in the microcapsules or waste stream, but also permitting microencapsulation of materials incompatible with traditional processes due to {HEAD ~ their sensitivity} to {TAIL ~ the presence} of organic solvents
