ABSTRACT:
A process is disclosed for continuously manufacturing minute capsules in a closed conduit under conditions of non-turbulent flow. The continuous microencapsulation process comprises in-line emulsification of intended capsule core material in a liquid manufacturing vehicle comprising negatively-charged polyelectrolyte material and methylol melamine or etherified methylol melamine followed by conduction of the emulsion, under non-turbulent flow conditions, through a tubular reactor maintained at a single, elevated temperature.
