METHOD FOR MANUFACTURING HYALURONATE FILM, AND HYALURONATE FILM MANUFACTURED THEREBY

Document Type and Number:

WIPO Patent Application WO/2018/164489

Kind Code:

A1

Abstract:

The present invention relates to a method for manufacturing a hyaluronate film, and a hyaluronate film manufactured thereby, and more particularly, to a method for manufacturing a hyaluronate film by solvent casting or an automatic applicator convenient for mass production, and a hyaluronate film which is manufactured thereby and can be used as a cosmetic mask pack, a patch for a drug and a medical device, or a film-type adhesion prevention agent and the like. The hyaluronate film according to the present invention, unlike existing liquid-phase products, is a film having a dried surface, and thus there is no concern about contamination from microorganisms and the production, management, distribution, and use thereof are simple, but also the film has excellent mechanical properties and thus can be used in various applications such as cosmetics, drugs, packs for medical devices, patches, and artificial skin.
