Preparation Method of Sodium Hyaluronate Film by Solvent Casting and Hyaluronate Film Prepared Thereof

摘要

The present invention relates to a process for producing a hyaluronate film by solvent casting and a hyaluronate film which can be used as a cosmetic mask pack, a patch for medicines, a medical device, a film-type adhesion inhibitor, and the like. The method for producing a hyaluronate film by solvent casting comprises the steps of: (a) dissolving a hyaluronate in a solvent to prepare a hyaluronate solution of 0.6 to 2.9% by volume; And (b) drying the hyaluronate solution by injecting the hyaluronate solution into a mold at a relative humidity of 30 to 70% and a drying temperature of 30 to 50 ° C. Since the hyaluronate film of the present invention is a dried film, unlike conventional liquid products, there is no fear of microbial contamination, and it is easy to produce / manage / distribute / treat, and also has excellent mechanical properties, , Packs for medical devices, patches, artificial skin, and the like.
