  • Patent number: 11298855
    Abstract: The present invention relates to a method of manufacturing a hyaluronate film and a hyaluronate film manufactured thereby, and more particularly to a method of manufacturing a hyaluronate film through a solvent-casting process or using an automatic film applicator that facilitates mass production and to a hyaluronate film manufactured thereby, which is useful as a mask pack for cosmetics, a patch for medicaments and medical devices, a film-type adhesion inhibitor, etc. Unlike conventional liquid products, the hyaluronate film according to the present invention has a dry surface and thus entails no concern about microbial contamination, is easy to produce/manage/distribute/use, and has superior mechanical properties, whereby it can be utilized for various applications such as packs, patches, artificial skin and the like for cosmetics, medicaments, and medical devices.

  • Patent number: 10994048
    Abstract: Provided is a hyaluronate fiber, and more particularly to a hyaluronate fiber, suitable for use in a surgical suture, a filler for cosmetic surgery, a lifting thread, a tissue-engineering scaffold, etc., and a method of manufacturing the same. Further, a method of manufacturing the hyaluronate fiber through melt spinning is provided, which includes (a) controlling the water content of a hyaluronate having a weight average molecular weight of 500˜3,000 kDa to 5˜20%, (b) producing a hyaluronate fiber by placing the hyaluronate having a controlled water content in a melt-spinning apparatus and performing heating to 150˜200° C. and then high-pressure spinning, and (c) hardening the surface of the hyaluronate fiber by immersing the hyaluronate fiber in an ethanol aqueous solution.
