[0023] As mentioned in the background art, the materials used in existing facial masks have certain limitations in terms of efficacy and cannot meet consumers' various needs for their skin. At the same time, some existing hydrogel facial masks are easily damaged during use, resulting in the loss of their effective ingredients, affecting the subsequent use effect.

[0024] To solve the above technical problems, an embodiment of the present invention provides a smart hydrogel mask, comprising: a matrix and functional components, wherein the matrix comprises at least: sodium carboxymethyl cellulose, polyethylene glycol, glycerin, benzalkonium bromide and water, wherein the weight percentage of the sodium carboxymethyl cellulose is 5%-10%.

[0025] Therefore, by adopting the technical solution described in the present invention and using a hydrogel matrix with a weight percentage of 5%-10% of sodium carboxymethyl cellulose, the moisturizing, antibacterial and nourishing properties of the smart hydrogel mask can be optimized.

[0026] In order to make the above-mentioned objects, features and beneficial effects of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0027] Specifically, the formula of this smart hydrogel mask mainly includes two parts: a matrix and functional components.

[0028] Furthermore, the matrix is ​​the foundation of the facial mask, primarily providing moisturizing, lubrication, and structural stability. The matrix's components include sodium carboxymethylcellulose, polyethylene glycol, glycerin, benzalkonium bromide, and water. Sodium carboxymethylcellulose comprises 5%-10% by weight, and its excellent moisture retention and film-forming properties provide the mask with excellent moisturizing effects and a stable structure. Polyethylene glycol and glycerin further enhance the mask's moisturizing properties, making it easier to adhere to the skin. Benzalkonium bromide, acting as a preservative, ensures the mask's hygienic safety.

[0029] Furthermore, the functional components are the core of the mask, primarily nourishing, repairing, and protecting the skin. These functional components include at least carbamide, vitamin E, petrolatum, and sodium alginate. Carbamide deeply nourishes the skin, vitamin E has antioxidant and anti-aging properties, petrolatum locks in moisture and keeps the skin moisturized, and sodium alginate enhances the mask's adsorption capacity, making it easier to adhere to the skin.

[0030] In addition, according to needs, the functional components can also include one or more of niacinamide, fulvic acid, fish collagen peptides, glycerol, etc. to further enhance the nourishing and repairing effects of the mask.

[0031] It is worth noting that the above-mentioned functional components are only listed as examples. In some other possible embodiments, other components with skin whitening, nourishing, hydrating and other effects may also be included, such as astaxanthin, Centella asiatica extract, etc.

[0032] In this application, the efficacy principle of the smart hydrogel mask lies in the following aspects.

[0033] First, the smart hydrogel mask's matrix is ​​primarily composed of sodium carboxymethylcellulose, polyethylene glycol, and glycerin, which interact with water molecules to form a three-dimensional, physically cross-linked solid form, the smart hydrogel. This three-dimensional network structure not only gives the mask excellent elasticity and stability, but also enables it to regulate the release and retention of water molecules within it according to changes in the user's skin temperature.

[0034] Furthermore, the functional components of the smart hydrogel mask, such as carbamide, vitamin E, petrolatum, and sodium alginate, are encapsulated within the smart hydrogel's three-dimensional network structure. When the external temperature changes, the smart hydrogel senses and responds to these changes, controlling the rate and order of release of the functional components. This intelligent release mechanism ensures that the mask provides the perfect amount of nourishment and repair for the skin at any temperature.

[0035] Furthermore, the smart hydrogel mask also uses ordered penetration technology, allowing the functional components to penetrate deep into the skin in an orderly manner. This technology utilizes the osmotic pressure and adsorption properties of the smart hydrogel, allowing the mask to fit tightly to the skin and effectively deliver the functional components deep into the skin through the microporous structure of the skin surface.

[0036] In a preferred embodiment, the weight percentages of the components of the smart hydrogel mask are: sodium carboxymethylcellulose: 8%, polyethylene glycol: 2%, glycerin: 8%, benzalkonium bromide: 0.15%, carbamide: 1%, vitamin E: 2%, petrolatum: 3%, sodium alginate: 2%, and purified water: 73.85%. This optimizes the effectiveness of the smart hydrogel mask in all aspects.

[0037] To verify that the technical solution of the present invention, using a hydrogel matrix with a weight percentage of 5%-10% sodium carboxymethyl cellulose, can optimize the moisturizing, antibacterial, and nourishing properties of the smart hydrogel mask, the inventors conducted the following experiments.

[0038] Experimental materials: sodium carboxymethyl cellulose (CMC), water, other components, skin moisture meter, bacterial culture dishes for antibacterial experiments, skin gloss and elasticity meter, and several volunteers.

[0042] B. Then, have the volunteers clean their faces and apply the corresponding facial mask, leaving it on for a certain period of time before removing it.

[0043] C. After applying the mask, use the skin moisture meter to measure the volunteers' skin moisture content again and record it.

[0044] D. Use a bacterial culture dish to test the antibacterial effect of the mask liquid through antibacterial experiments.

[0045] E. Use a skin gloss and elasticity meter to assess changes in the gloss and elasticity of the volunteers' skin.

[0046] F. Data Recording: Detailed record of all data during the experiment, including skin moisture content, antibacterial effect, skin gloss and elasticity changes, etc.

[0047] Experimental results:

[0048] 1. Moisturizing effect test results at different CMC ratios

[0049] The comparison data of skin moisture content before and after the experiment are shown in the following table:

[0050] Experimental groups CMC proportion (%) Skin moisture content before the experiment (%) Skin moisture content after the experiment (%) Moisturizing rate (%) Group 1 5.0 35.0 63.0 80.0 Group 2 8.0 35.0 67.5 93.1 Group 3 10.0 35.0 66.0 88.6 Control group 1 3.0 35.0 55.0 57.1 Control group 2 12.0 35.0 58.0 65.7

[0051] The schematic diagram of the effect of CMC ratio on moisturizing effect is as follows Figure 1 .

[0053] The comparative data of antibacterial effect are shown in the following table:

[0054] Experimental groups CMC proportion (%) Antibacterial rate (%) Group 1 5.0 90.0 Group 2 8.0 95.0 Group 3 10.0 92.0 Control group 1 3.0 75.0 Control group 2 12.0 80.0

[0055] The schematic diagram of the effect of CMC ratio on antibacterial effect is as follows Figure 2 .

[0056] 3. Observation results of nourishing effects under different CMC ratios

[0057] The observation data of the nourishing effect are shown in the following table:

[0058] Experimental groups CMC proportion (%) Skin moisture content after use (%) Gloss changes Elastic changes Group 1 5.0 63.0 +3 levels +2 levels Group 2 8.0 67.5 +4 levels +3 levels Group 3 10.0 66.0 +3 levels +2 levels Control group 1 3.0 58.0 +2 levels +1 level Control group 2 12.0 60.0 +2 levels +1 level

[0059] Based on these experimental results, it can be concluded that: "Using the technical solution of the present invention and utilizing a hydrogel matrix containing 5%-10% sodium carboxymethylcellulose by weight can optimize the moisturizing, antibacterial, and nourishing properties of the smart hydrogel mask." In particular, when the CMC content is 8%, the moisturizing, antibacterial, and nourishing effects are the best.

[0060] To solve the above technical problems, an embodiment of the present invention further discloses a method for producing a smart hydrogel mask.

[0061] Specifically, the production method of the smart hydrogel mask mainly includes the following steps:

[0062] 1. Prepare the matrix solution

[0066] 3. Pour into mold and cool to solidify

[0067] The smart hydrogel mask liquid is poured into a pre-prepared mold and then placed in a cooling environment to cool and solidify. During the cooling process, the components gradually cross-link to form a stable three-dimensional network structure.

[0068] 4. Optimize the shape of the mask
