METHOD FOR MANUFACTURING POLYDIOXANONE PARTICLES FOR FILLER

摘要

The present invention relates to a method for manufacturing polydioxanone (PDO) particles for a filler and, more specifically, to a method for manufacturing polydioxanone particles, the method comprising a step of mixing a polydioxanone solution dissolved in a perfluoro-alcohol with a polymer emulsified solution containing a terpolymer of polyethylene oxide - polypropylene oxide - polyethylene oxide at a predetermined ratio to generate polydioxanone particles, and then recovering the polydioxanone particles through aging and washing. The polydioxanone particles manufactured by the manufacturing method of the present invention can be favorably used as an injection for regenerating skin tissues.
