[0018] The purposes, functional features and advantages of the present application will be further described with reference to the accompanying drawings in conjunction with embodiments. DETAILED DESCRIPTION

[0019] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below, and it should be understood that the following embodiments are only used to explain the present application and not used to limit the present application.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the claimed subject matter belongs.

[0021] In order to facilitate understanding of the embodiments, the following explains the symbolic terms:

[0022] PVA (Polyvinyl Alcohol) is polyvinyl alcohol, PEO (Poly Ethlene Oxide) is polyethylene oxide, and PVP (Polyvinyl Pyrrolidone) is polyvinyl pyrrolidone.

[0023] Ordinary hands are subjected to a large amount of work and external factors, and the skin aging and roughening speed is also relatively fast, and color spots are also easily grown on the back of the hand. The hand film can deeply nourish the skin and repair the damaged skin due to environmental pollution and sun exposure, and has an effect on wrinkles, dry lines and other problems on the skin caused by oxidation.

[0024] However, the current hand film has a relatively complicated use method, and it is difficult to achieve rapid and efficient skin care.

[0025] To solve the above problems, the present application provides a nanofiber hand film comprising: a water-soluble polymer and an efficacy component, wherein the nanofiber hand film reacts with an oil compound to become a gel state when used; and wherein the water-soluble polymer is in a nanofiber structure. In an embodiment, the water-soluble polymer forms a three-dimensional network structure after being crosslinked with the efficacy component, so that the intermolecular force is enhanced, and the film strength is improved, and the nanofiber hand film swells when in contact with the oil compound, and exhibits a gelable feature. The water-soluble polymer forms a nanofiber structure by an electrospinning method, and has high porosity, good pore connectivity, and strong uniformity of fiber diameter, which can improve the dispersibility of the efficacy component on the surface and in the pores of the nanofiber, and the active ingredient exists in the nanofiber in the form of a small particle, and has a higher dissolution or release efficiency. The nanofiber as a carrier has a large specific surface area and a porous structure, and has a strong mutual penetration with other substances, which is extremely beneficial to the diffusion and dissolution of the efficacy component, and improves the transdermal permeation amount and the transdermal absorption of the efficacy component.

[0026] Further, the mass of the water-soluble polymer accounts for 8%-12% of the mass of the nanofiber hand film. In an embodiment, the higher the concentration of the water-soluble polymer solution, the greater the viscosity and the surface tension, and the droplet breakup ability after leaving the nozzle decreases with the increase of the surface tension. Generally, when other conditions are constant, the fiber diameter increases with the increase of the concentration.

[0027] Further, the water-soluble polymer comprises at least one of PVA, PEO, and PVP. In an embodiment, PVA is selected as the main electrospinning material, and the PVA has good biocompatibility and degradability, and good film-forming and mechanical properties.

[0028] Further, the efficacy component comprises at least one of a moisturizing component, a skin-soothing component, an anti-wrinkle component, an antibacterial component, and a whitening component. In an embodiment, one or more of the moisturizing component, the skin-soothing component, the anti-wrinkle component, the antibacterial component, and the whitening component can be added according to the requirements, and they are attached to the polymer nanofiber or the pores thereof, and have excellent dispersibility, and the various components can play a synergistic effect.

[0029] Further, the moisturizing component includes at least one of hyaluronic acid, biosaccharide gum; and / or, the toning component includes at least one of menthol, a cooling agent; and / or, the anti-wrinkle component includes at least one of hamamelis virginiana, centella asiatica extract, aloe barbadensis miller extract, vitis vinifera seed extract, a polypeptide, an oligopeptide, retinoic acid; and / or, the antibacterial component includes at least one of vitamin C, a soothing peptide, propolis; and / or, the whitening component includes at least one of niacinamide, arbutin. In an embodiment, the moisturizing component is hyaluronic acid, which is also known as hyaluronan, can carry water and quickly penetrate into the epidermis and dermis, has the biological activity of deep moisturizing, removing free radicals, repairing damaged cells, improving cell activity, soothing, anti-inflammatory, regulating immune function, etc. In an embodiment, the toning component is menthol, which mainly has the effects of stopping itching and pain, calming the skin, and cooling, and can be used to improve symptoms caused by inflammatory lesions or external injuries. In an embodiment, the anti-wrinkle component is a polypeptide, which has the characteristics of inhibiting vesicle release of neurotransmitters, weakening muscle contraction, and reducing wrinkle formation. In an embodiment, the antibacterial component is propolis, which has the effects of moisturizing, promoting tissue regeneration, anti-inflammatory, and pain relief. In an embodiment, the whitening component is arbutin, which can inhibit the activity of tyrosinase in the body, prevent the formation of melanin, reduce skin pigment deposition, and remove freckles and spots, and also has the effects of sterilization and anti-inflammatory

[0030] To solve the above problems, the application further provides a preparation method of the nanofiber hand film, which comprises the following steps: mixing a water-soluble polymer, an efficacy component, and deionized water, stirring to obtain a spinning precursor solution; adding the spinning precursor solution into an electrostatic spinning device for treatment, and then drying to obtain the nanofiber hand film. In an embodiment, different skin care efficacy components are first blended with the water-soluble polymer in a solvent to prepare spinning precursor solutions with different mass concentrations, and then placed in a liquid supply pump, and the nanofiber hand film is prepared by using the electrospinning method. During spinning, water is lost by evaporation, and under the action of an electric field, the spinning solution is pulled into nanoscale solid fibers, thereby weaving a nanofilm with the efficacy component attached to the skin.

[0031] Further, in the step of "mixing a water-soluble polymer, an efficacy component, and deionized water, stirring to obtain a spinning precursor solution", the efficacy component includes at least one of a moisturizing component, a toning component, an anti-wrinkle component, an antibacterial component, and a whitening component. They are attached to the polymer nanofiber or the mesh thereof, and have excellent dispersibility, and the various components can play a synergistic effect.

[0032] Further, the moisturizing ingredient includes at least one of hyaluronic acid, biosaccharide gum; and / or, the toning ingredient includes at least one of menthol, cooling agent; and / or, the anti-wrinkle ingredient includes at least one of Hamamelis virginiana, Centella asiatica extract, Aloe barbadensis Miller (Lavender) extract, Vitis vinifera (grape) seed extract, polypeptide, oligopeptide, retinoic acid; and / or, the antibacterial ingredient includes at least one of vitamin C, soothing peptide, propolis; and / or, the whitening ingredient includes at least one of niacinamide, arbutin. In an embodiment, the kind of efficacy ingredient is added according to the requirement, and the concentration of the added efficacy ingredient does not affect the performance of the electrospun nanofiber.

[0033] Further, in the step of "mixing the water-soluble polymer, the efficacy ingredient and the deionized water, stirring to obtain a spinning precursor solution", the electrospinning device is set at a voltage of 15-18 kV; and / or, the electrospinning device is set at a temperature of 10-45 degrees Celsius; and / or, the electrospinning device is set at an automatic liquid supply speed of 0.5-1 ml / h. In an embodiment, the electrospinning method is set at a spinning voltage of 16 kV, a humidity of 30%, a sliding speed of 0.7 mL / s, an automatic liquid supply speed of 0.7 mL / h, and a temperature of <50°C, to prepare a nanofiber hand film. The electrospinning reaction conditions are matched with the properties of the spinning precursor solution to achieve excellent spinning effect. During electrospinning, the ejection device is filled with charged polymers. Under the action of electric field force and surface tension, the ejection flow is thinned in high-speed oscillation, forming nanoscale fibers. If the humidity is higher than 50%, water will concentrate on the surface of the fibers, thereby affecting the morphology of the nanofiber. If the humidity is too low, the volatile solvent may dry quickly, and the evaporation speed of the solvent may be faster than its removal speed from the needle, thereby causing needle blockage, so that the electrospinning process can only continue for a very short time. The size of the voltage is matched with the mechanical relationship between the electric field force of the jet flow and the solution viscous stress, and together with the sample rate and humidity, it affects the results of electrospinning.
