Method for microencapsulating a solid substance

摘要

A method of microencapsulating a biologically active solid substance that is characterized by polymerizing a monomer that is polymerizable by condensation in a dispersion comprising i) a solution comprising a nonionic substance and ii) a biologically active solid substance that is insoluble or difficult to dissolve in said solution, wherein the nonionic substance is effective for dispersing the biologically active substance in said solution, is an effective method for producing a microencapsulated composition without aggregation.
