Nanofiber moisturizing facial mask with viscous hydroxyl functional group on surface as well as preparation method and application of nanofiber moisturizing facial mask

The invention provides a preparation method of a nanofiber moisturizing facial mask with a viscous hydroxyl functional group on the surface, and belongs to the field of skincare products. The preparation method comprises the following steps: mixing glycerinum, hyaluronic acid, polyethylene oxide, urea, allantoin, sodium pyrrolidonecarboxylate and a solvent so as to obtain a spinning liquid, carrying out electrostatic spinning with the spinning liquid one side of a facial mask substrate, and pasting the obtained viscous nanofiber layer to a protection layer, thereby obtaining the nanofiber moisturizing facial mask. According to the facial mask, glycerinum, hyaluronic acid, polyethylene oxide, urea, allantoin and sodium pyrrolidonecarboxylate are smartly mixed to prepare the spinning liquid,the hydroxyl functional group of the glycerinum before being formed as a nanofiber is difficult to be in sufficient contact with the facial mask substrate and has no viscosity, after the glycerinum is prepared as the nanofiber through electrostatic spinning, the surface of the glycerinum can be greatly increased, and the hydroxyl functional group can be in sufficient contact with the facial masksubstrate and has viscosity, so that the binding performance of the viscous nanofiber and the facial mask substrate can be ensured.
