Title:
PREPARATION METHOD OF MICROCAPSULES
Document Type and Number:
WIPO Patent Application WO/2020/009438
Kind Code:
A1
Abstract:
The objective of the present invention is to provide a method for preparing surface-modified microcapsules, the method comprising, after preparing a pickering emulsion using inorganic nanoparticles and acrylic monomers containing biodegradable ester groups, preparing capsules through polymerization of the emulsion, and modifying the surfaces of the capsules with an amine-based monomer, thereby enhancing the adhesion of the fragrance capsules to fabric and providing excellent fragrance persistence even after use. The microcapsules are eco-friendly due to biodegradation of the ester groups.
