Description
Technical Field
The invention relates to a power generation membrane, in particular to a power generation membrane containing a water-soluble material and a skin dressing containing the power generation membrane.
Background
Skin care products on the market seal local skin and prevent the evaporation of skin moisture, thereby increasing the water content of the skin and improving the skin hydration degree; meanwhile, the temperature of the skin rises, which is beneficial to the penetration of molecules and promotes the absorption of active ingredients to a certain extent. Therefore, some doctors believe that the dressing is equivalent to the package treatment of dermatology, and the absorption of skin care products by the skin can be increased. In addition, some chemicals with ions or charges are absorbed into the human body through the skin, and an ion introduction method (Iontophoresis) can be used for assistance.
In recent years, paper batteries (printed batteries) have been developed rapidly, and are very environmentally friendly due to low contamination of materials used therein, and the simple production process is advantageous for reducing the cost and making it economically competitive with the light and thin profile. The paper battery has the characteristics of a capacitor like a lithium ion battery, and can provide a long-term and stable power output. Therefore, the development of paper batteries (printed batteries) provides another approach to the application of iontophoresis technology.
However, when a paper battery is used to deliver skin care products into the skin by iontophoresis, the energy that can be stored in the paper battery is limited due to its light and thin characteristics, so that the skin care components in the aqueous solution are difficult to move by electrical repulsive force.
In addition, generally, the dressing is soaked in an aqueous solution containing a skin care product during the sale of the dressing, and the dressing is set to have a short shelf life because of the fear of deterioration of the skin care product, which is disadvantageous in terms of improvement of economic competitiveness.
Disclosure of Invention
In view of the above problems, the present invention discloses a power generation membrane and a skin dressing comprising the power generation membrane, which are useful for solving the problems that skin care ingredients are difficult to enter deep layers of skin by an iontophoresis method and the shelf life of products is short.
The invention discloses a power generation membrane, which comprises a membrane body, an electrode material and a water-soluble material. The electrode material is arranged on the membrane body, and the water-soluble material is arranged on the membrane body. The water soluble material comprises an ionic compound.
The skin dressing material disclosed by the invention comprises the power generation membrane.
According to the power generation membrane and the skin dressing material disclosed by the invention, the water-soluble material containing the ionic compound is arranged on the membrane body. When the power generation membrane is soaked by liquid, the water-soluble material is dissolved to increase the conductivity of the liquid, and the water-soluble material of the functional material is favorably fed into the deep layer of the skin together with the functional material through an iontophoresis method. Because the dissolved water-soluble material and the porous channel formed in the membrane body after the water-soluble material is dissolved can improve the conductivity, the power generation membrane does not need to additionally contain a substance for improving the conductivity.
Further, the skin dressing disclosed in the present invention is not soaked in an aqueous solution containing an ionic compound, but is provided with a water-soluble material containing an ionic compound on the film body when the product is sold commercially, and therefore, there is no concern about deterioration of the aqueous solution, which contributes to extension of the shelf life of the skin dressing.

For example, in the embodiment of fig. 1, the water-soluble material particles may be a dry powder; in the embodiment of fig. 3, the water-soluble material unit may be a dry sheet-like body aggregated from powder; in the embodiment of fig. 5, the water-soluble material unit may be a gel sheet.
The functional material may contain a skin care product having a cosmetic effect on human skin or may contain a pharmaceutical ingredient having a therapeutic effect on human skin, for example, the functional material may contain anti-wrinkle agents such as carotenoids, ascorbic acid (vitamin C) and vitamin E and other vitamin preparations, in another embodiment, the water-soluble material may further contain a moisturizer of the type such as vitamin A (retinol), α hydroxy acids, β hydroxy acids (salicylic acid), combination hydroxy acids and polyhydroxy acids, in yet another embodiment, the functional material may further contain hydrolyzed and soluble collagen and other hyaluronic acids, in yet another embodiment, the functional material may further contain an anti-cellulite agent such as aminophylline and others, in yet another embodiment, the functional material may further contain a skin bleaching agent such as retinoic acid, hydroquinone and peroxide and others, in yet another embodiment, the functional material may further contain a skin bleaching agent such as retinoids, phytoalexin, such as retinoids, renin-dependent vasopressive hormone releasing hormone(s), vasopressive hormone releasing hormone, vasopressin, and other active antagonists, vasopressin, and other active antagonists, vasopressin, and other active antagonists, vasopressin, and other active antagonists, vasopressin, E, vasopressin, and other active antagonists, vasopressin, E, and other active antagonists, vasopressin, E, and other active, E, and other active.
In an embodiment, the functional material may further comprise a superabsorbent polymer. Superabsorbent polymers refer to materials that are capable of absorbing and retaining at least about 10 times their weight in body fluids under a pressure of 0.5 psi. The superabsorbent polymer particles may be inorganic or organic cross-linked hydrophilic polymers such as polyvinyl alcohol, polyethylene oxide, cross-linked starch, guar gum, xanthan gum, and other materials known in the art of absorbent article manufacture.
Hereinafter, specific examples of the present invention and comparative examples are provided to further illustrate the efficacy of the present invention.
[ example ]
There is provided a mask (i.e., skin dressing) comprising a power generation membrane having the structure as shown in fig. 1 and a functional material. In the power generation diaphragm, the diaphragm body is a non-woven fabric, the electrode material comprises zinc particles and copper particles, and the water-soluble material comprises sodium chloride. The functional material is vitamin C. When in use, the facial mask is soaked in pure water and then attached to the skin of a human face.
[ comparative example ]
A mask is provided, comprising a power generating membrane and a functional material. The power generation membrane comprises a membrane body and an electrode material, but does not comprise a water-soluble material. The membrane body is non-woven fabric, the electrode material comprises zinc particles and copper particles, and the functional material is vitamin C. When in use, the facial mask is soaked by aqueous solution containing sodium chloride and then is attached to the skin of a human face.
[ Effect of iontophoresis ]
FIG. 9 is a fluorescent image showing the ion implantation effect of the examples and comparative examples of the present invention. The functional materials in the examples and comparative examples were modified with green fluorescent molecules in advance. The masks of the example and comparative examples after being soaked were attached to artificial skin, respectively, and then the depth of vitamin C entering the artificial skin was observed. Referring to fig. 9, fluorescence (white area) can be detected in the deeper skin area by using the wet mask containing water-soluble material, which indicates that the functional material of the embodiment can enter the deeper skin area by the iontophoresis method. Since the water-soluble material dissolved in water is accumulated in the vicinity of the electrode material, resulting in high conductivity of the liquid around the electrode material, the power generation membrane can effectively deliver the water-soluble material together with the functional material into the skin. In addition, the porous channel formed in the membrane body after the water-soluble material is dissolved can enlarge the contact total area of the power generation membrane and the liquid, and also contributes to increasing the conductivity.
In summary, in the power generation membrane and the skin dressing disclosed in the present invention, the water-soluble material containing the ionic compound is disposed on the membrane body. When the power generation membrane is soaked by liquid, the water-soluble material is dissolved to increase the conductivity of the liquid, and the water-soluble material of the functional material is favorably fed into the deep layer of the skin together with the functional material through an iontophoresis method. Because the dissolved water-soluble material and the porous channel formed in the membrane body after the water-soluble material is dissolved can improve the conductivity, the power generation membrane does not need to additionally contain a substance for improving the conductivity.
Further, the skin dressing disclosed in the present invention is not soaked in an aqueous solution containing an ionic compound, but is provided with a water-soluble material containing an ionic compound on the film body when the product is sold commercially, and therefore, there is no concern about deterioration of the aqueous solution, which contributes to extension of the shelf life of the skin dressing.
