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 mask with viscous hydroxyl functional groups on the surface, which belongs to the field of skin care products. Mix glycerin, hyaluronic acid, polyethylene oxide, urea, allantoin, sodium pyrrolidone carboxylate, and a solvent to obtain a spinning solution and perform electrospinning on one side of the mask substrate to obtain a viscous nanofiber layer. The protective layer is attached and you get a nanofiber moisturizing mask. In the present invention, the spinning liquid is skillfully mixed with glycerin, hyaluronic acid, polyethylene oxide, urea, allantoin, and sodium pyrrolidone carboxylate. After the glycerin is electrospun into nanofibers, its surface area is greatly increased, and the hydroxyl functional group fully contacts the mask substrate, which is sticky, ensuring the bonding performance between the viscous nanofibers and the mask substrate.

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...
