Document Type and Number:
WIPO Patent Application WO/2021/132858
Kind Code:
A1
Abstract:
Presented are a method for manufacturing biodegradable polymer microparticles for a filler and a method for manufacturing an injection comprising the biodegradable polymer microparticles for a filler manufactured by the method. The method for manufacturing biodegradable polymer microparticles for a filler comprises the steps of: providing a first composition comprising a biodegradable polymer and an organic solvent which is miscible with water; providing a second composition comprising a surfactant and water; preparing a mixture by mixing the first composition and the second composition; preparing a third composition comprising polymer microparticles by stirring the mixture; and separating the polymer microparticles from the third composition.
