METHOD FOR FABRICATING MICROPARTICLES IN EMULSION BY MODIFICATION OF THE CHEMICAL COMPOSITION OF THE DISPERSED PHASE AFTER EMULSIFICATION

摘要

The method for producing microparticles is characterized in that it comprises the following steps: preparation of an emulsion of a solution of a substance or a mixture of substances in a dispersing liquid wherein said substance or said mixture are substantially insoluble; incorporating to said dispersed phase a chemical agent substantially insoluble in the dispersing liquid so as to cause within the dispersed phase a chemical or physicochemical reaction responsible for the formation of microparticules which are then isolated.
