Problems solved by technology

However, the adhesive material may cause skin allergies, and the method of chemical modification will affect the activity of the active ingredients and increase the cost. For example, Chinese patent CN104114057A discloses a mask impregnated with liquid cosmetic preparations, and the nanofiber layer is bonded To the nonwoven fabric layer, the adhesive materials used include: acrylic, polyurethane, polyester and silicone
Although these viscous materials are inherently sticky, they do not have a moisturizing function

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of skin care products, in particular to a nanofiber moisturizing facial mask with viscous hydroxyl functional groups on the surface, a preparation method and application thereof. Background technique [0002] Ordinary nanofiber spinning facial mask comprises nanofiber layer and facial mask substrate layer, and wherein nanofiber layer peels off easily with facial mask substrate layer, and the solution in the prior art is to add one layer of macromolecule material adhesive in the middle of two layers, Or use chemical methods to make a chemical reaction between the two layers to increase the adhesion. However, the adhesive material may cause skin allergies, and the method of chemical modification will affect the activity of the active ingredients and increase the cost. For example, Chinese patent CN104114057A discloses a mask impregnated with liquid cosmetic preparations, and the nanofiber layer is bonded To t...
