Description

Technical Field

[0001] The present application relates to the technical field of textile materials, and in particular to a peppermint composite facial mask cloth and a preparation method thereof. Background Art

[0002] Huaxanthin is derived from the natural plant Zanthoxylum bungeanum, and is a safe, non-irritating skin care ingredient. As one of the ingredients of facial masks, Huaxanthin can promote the synthesis of collagen, help the skin regain its firmness and elasticity, and solve the problem of sagging skin. At the same time, Huaxanthin has significant antioxidant capacity, which can effectively remove free radicals in the skin and reduce skin aging, pigmentation and other problems. It can also reduce the occurrence of skin allergies and inflammation, and protect the skin from damage by the external environment. In addition, the volatile oil components contained in Huaxanthin can effectively inhibit and kill a variety of bacteria, including skin fungi, and help keep the skin fresh and healthy. Therefore, using Huaxanthin as an effective ingredient in facial masks is highly competitive and attractive in the market.

[0003] After adding pepper, the existing single-layer hydrophilic mask cloth cannot be evenly distributed on the mask cloth, resulting in excessively high pepper concentrations in contact with some skin, while other skin cannot be exposed to enough pepper, thus affecting the overall absorption effect. At the same time, the skin's absorption mechanism requires a certain hydrophobic environment to promote the absorption of certain ingredients. The single-layer hydrophilic mask cloth may not provide such an environment, resulting in the obstruction of pepper absorption. In addition, the skin has a natural barrier function that can prevent external harmful substances from entering the body. At the same time, it will also hinder the absorption of some beneficial substances. As an active ingredient, pepper needs to pass through a specific channel or carrier to enter the skin. The single-layer hydrophilic mask cloth may not be able to effectively penetrate this barrier. As a result, the absorption effect of pepper in the mask is poor, resulting in a waste of pepper. Therefore, how to improve the absorption effect of pepper in the pepper composite mask cloth is a technical problem that needs to be solved at present. Summary of the invention

[0004] The present application provides a peppermint composite facial mask cloth and a preparation method thereof to solve the following technical problem: how to improve the absorption effect of peppermint in the peppermint composite facial mask cloth.

[0007] S2, mixing pure cotton fiber, hydrophobically modified silica and a strong alkali solution, and performing a microwave-ultrasound combined treatment, so that the hydrophobically modified silica is adsorbed inside the pure cotton fiber to obtain hydrophobic fiber; wherein the mass ratio of the pure cotton fiber to the hydrophobically modified silica is (10-20):1, the mass concentration of the strong alkali solution is 0.1-0.8%, and the parameters of the microwave-ultrasound combined treatment include: microwave power of 50-150W, ultrasonic power of 200-300W, and combined treatment time of 10-90s;

[0009] The nano-silica, hexadecyltrimethoxysilane, a surfactant and deionized water are subjected to high-pressure homogenization treatment to obtain the hydrophobically modified silica; the mass ratio of the nano-silica, the hexadecyltrimethoxysilane and the surfactant is (50-60):(10-20):(2-5);

[0010] S3, making the hydrophilic fiber into a hydrophilic non-woven fabric, and making the hydrophobic fiber into a hydrophobic non-woven fabric;

[0011] S4, stacking the hydrophilic non-woven fabric and the hydrophobic non-woven fabric, and then hot-pressing and compounding them to obtain a facial mask substrate;

[0012] S5, immersing the facial mask base material in the pepperin solution, and then drying to obtain the pepperin composite facial mask cloth.

[0013] Optionally, the pressure of the high-pressure homogenization treatment is 100-150 MPa, and the number of times of the high-pressure homogenization treatment is 2-5 times.

[0014] Optionally, the carboxymethylation modification uses a chloroacetic acid aqueous solution, and the mass concentration of the chloroacetic acid aqueous solution is 10-20%.

[0015] Optionally, the hot pressing compound includes the following parameters: hot pressing temperature is 80-150° C., hot pressing pressure is 1-5 MPa, and hot pressing time is 1-5 min.

[0016] Optionally, the pepper liquid is composed of the following chemical components, measured by mass: 1 to 5 parts of pepper, 60 to 80 parts of ethanol, 10 to 20 parts of glycerol, 5 to 15 parts of propylene glycol, 0.1 to 1 part of sodium ascorbate, 0.1 to 1 part of menthol, and 0.1 to 5 parts of phosphate buffer.

[0017] In a second aspect, the present application provides a peppermint composite facial mask cloth prepared by the preparation method of the peppermint composite facial mask cloth described in any one of the first aspects, wherein the peppermint composite facial mask cloth comprises a hydrophilic non-woven fabric and a hydrophobic non-woven fabric arranged in layers.

[0018] Optionally, the hydrophilic non-woven fabric is arranged on both outer sides of the zanthoxylum composite facial mask fabric.

[0019] Optionally, the thickness of the Zanthoxylum bungeanum composite facial mask cloth is 0.15 to 0.25 mm.

[0022] The present application provides a method for preparing a composite facial mask cloth of peppercorns, and rationally designs the stacked structure of hydrophilic non-woven fabrics and hydrophobic non-woven fabrics. First, the hydrophilic layer can efficiently absorb peppercorns liquid, while the hydrophobic layer slows down its penetration rate, allowing peppercorns to have more time to be evenly distributed in the hydrophilic layer, thereby increasing the contact area and contact time with the skin and promoting absorption; secondly, the waterproof performance of the hydrophobic non-woven fabric effectively prevents the peppercorns liquid from evaporating or losing too quickly, ensuring that peppercorns remain on the mask substrate for a longer time, thereby extending the contact time with the skin and improving the absorption efficiency. Finally, the multi-layer mask cloth simulates the natural structure of the skin, the hydrophilic layer retains the moisture of the skin, and the hydrophobic layer reduces excessive moisture loss, jointly creating a more favorable penetration environment, which helps the active ingredients of peppercorns enter the skin through specific channels or carriers, thereby improving the absorption effect of peppercorns in the composite facial mask cloth of peppercorns.

[0029] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0030] Unless otherwise specified, various raw materials, reagents, instruments and equipment used in this application can be purchased from the market or prepared by existing methods.

[0031] like Figure 1 As shown, the present application provides a method for preparing a composite facial mask cloth containing peppermint, the method comprising the following steps:

[0032] S1, performing carboxymethyl modification on pure cotton fiber to graft carboxymethyl groups into the molecular chain of the pure cotton fiber to obtain hydrophilic fiber;

[0033] In some embodiments, the carboxymethylation modification uses a chloroacetic acid aqueous solution, and the mass concentration of the chloroacetic acid aqueous solution is 10-20%.

[0034] In some embodiments, the specific process of the carboxymethylation modification is: treating the pure cotton fiber with a caustic soda solution to swell it to form sodium cellulose, and then reacting it with an aqueous solution of chloroacetic acid (as an etherifying agent) to graft carboxymethyl groups into the fiber molecular chain. After the reaction is completed, washing the modified cotton fiber to remove unreacted reagents and by-products, and adjusting the pH value and stability of the fiber.

[0035] The carboxymethylation modification of pure cotton fiber mainly utilizes the reaction between chloroacetic acid aqueous solution and the fiber interior to graft carboxymethyl groups onto the fiber molecular chain. These highly polar hydrophilic groups can increase the number of free polar free groups inside the fiber, thereby improving the fiber's ability to bind water molecules and enhancing the fiber's hydrophilicity.

[0036] In some embodiments, the carboxymethylation modification is carried out at a temperature of 60 to 80° C. and for a time of 30 to 50 minutes.

[0037] S2, mixing pure cotton fiber, hydrophobically modified silica and a strong alkaline solution, and subjecting the mixture to a microwave-ultrasound combined treatment, so that the hydrophobically modified silica is adsorbed inside the pure cotton fiber to obtain hydrophobic fiber;

[0038] In some embodiments, the mass concentration of the strong alkaline solution is 0.1-0.8%.

[0039] In some embodiments, the mass ratio of the pure cotton fiber to the hydrophobically modified silica is (10-20):1.

[0040] Hydrophobically modified silica can give the mask material better breathability and antibacterial properties while maintaining its hydrophobicity, helping to keep the mask fresh and hygienic.

[0041] Strong alkali solution can destroy the wax layer and part of the cellulose structure on the surface of pure cotton fiber, exposing more hydroxyl groups, which is convenient for combining with hydrophobically modified silica. At the same time, strong alkali can also promote the deposition and adsorption of silica on the fiber surface. The mass concentration of strong alkali solution is limited to 0.1-0.8%, which can promote the swelling of fiber, make it easier for hydrophobically modified silica to enter the fiber and form a firm bond with the fiber.

[0042] In some embodiments, the parameters of the microwave-ultrasound combined treatment include: microwave power of 50-150 W, ultrasonic power of 200-300 W, and combined treatment time of 10-90 s.

[0043] Microwave radiation can quickly heat the fiber and solution system, promote the molecular movement inside the fiber, accelerate water evaporation and chemical reaction rate. In addition, microwaves can also excite polar molecules (such as water molecules) inside the fiber, causing them to rotate and rub, thereby further promoting the swelling of the fiber and the opening of the microporous structure.

[0044] Ultrasonic waves produce strong cavitation effects, microjets and shock waves in the solution, which can destroy the structure of the fiber surface, increase its roughness and specific surface area, and facilitate the adsorption of hydrophobically modified silica. At the same time, ultrasonic waves can also promote the dispersion and mixing of particles in the solution, increasing the contact opportunity between hydrophobically modified silica and fibers.

[0045] Microwave-ultrasound combined treatment can bring into play the complementary effects of the two. Microwave heating and ultrasonic cavitation effect promote each other, accelerating the swelling and chemical reaction process of the fiber; at the same time, the ultrasonic cavitation effect and micro-jet action can enhance the roughness of the fiber surface and the contact area with the hydrophobically modified silica, thereby improving the bonding force.

[0046] In some embodiments, the method for preparing the hydrophobically modified silica comprises:

[0047] Nano-silicon dioxide, hexadecyltrimethoxysilane, a surfactant and deionized water are subjected to high-pressure homogenization treatment to obtain the hydrophobically modified silicon dioxide.

[0048] In some embodiments, the mass ratio of the nano-silica, the hexadecyltrimethoxysilane and the surfactant is (50-60):(10-20):(2-5).

[0049] Nano-silica has high activity due to its tiny size and a large number of surface hydroxyl groups, and is easy to react with modifiers. The alkoxy part of HDTMS can undergo condensation reaction with the hydroxyl groups on the surface of nano-silica to form covalent bonds, thereby introducing hydrophobic groups onto the surface of silica. Surfactants can reduce the surface tension of the solution and help to evenly distribute the modifier on the surface of nano-silica. At the same time, they can also stabilize the dispersion system and prevent the nanoparticles from agglomerating during the reaction. In addition, surfactants can also improve the effect of high-pressure homogenization treatment, making the material more delicate and homogeneous.

[0050] In some embodiments, the pressure of the high-pressure homogenization treatment is 100-150 MPa, and the number of times of the high-pressure homogenization treatment is 2-5 times.

[0051] High-pressure homogenization is a technology that refines and homogenizes materials through high pressure and shear force. High-pressure homogenization of the mixture can further refine the nano-silica particles, promote the uniform distribution of the modifier on the particle surface, and improve the stability and performance of the product. This treatment method has significant advantages in the preparation of hydrophobic modified silica, such as improving the hydrophobic effect, enhancing the stability and durability of the product, etc.

[0052] In some embodiments, the surfactant is composed of sodium dodecylbenzene sulfonate and glyceryl monostearate, and the mass ratio of sodium dodecylbenzene sulfonate to glyceryl monostearate is (1-3):1.

[0053] S3, making the hydrophilic fiber into a hydrophilic non-woven fabric, and making the hydrophobic fiber into a hydrophobic non-woven fabric;

[0054] In some embodiments, the fibers are formed into a nonwoven fabric using a hydroentanglement process.

[0055] It should be noted that the specific method of making non-woven fabrics from fibers by hydroentanglement is as follows: the fibers are loosened by an opener, and then arranged into a mesh structure by a combing process to form a fiber web. The fiber web is fed into a hydroentanglement machine, and high-pressure water is sprayed onto the fiber web through a nozzle at a very high speed. The pressure of the water flow causes the fibers to entangle with each other and combine tightly to form a non-woven fabric with a certain strength.

[0056] S4, stacking the hydrophilic non-woven fabric and the hydrophobic non-woven fabric, and then hot-pressing and compounding them to obtain a facial mask substrate;

[0057] In the process of preparing the composite facial mask cloth of pepper extract in the present embodiment, the hydrophilic non-woven fabric and the hydrophobic non-woven fabric are stacked and placed and hot-pressed to form a facial mask substrate, and the specific functions are as follows:

[0058] (1) Improve the moisturizing properties of facial masks

[0059] Function of the hydrophilic layer: The hydrophilic nonwoven fabric can quickly absorb and lock in moisture to keep the mask moist. This is crucial for the penetration and absorption of active ingredients such as peppermint on the skin, because a moist environment helps the dissolution and transmission of ingredients.

[0060] Protection of the hydrophobic layer: The hydrophobic non-woven fabric can form a protective barrier to prevent water from evaporating too quickly, thereby prolonging the moisturizing effect of the mask. This is of positive significance for maintaining the skin's moisture and improving the skin care experience.

[0061] (2) Enhance the fit and comfort of the mask

[0062] Improved fit: Hydrophilic nonwoven fabrics have good air permeability and softness, and can fit closely to the skin, reducing the generation of bubbles and gaps. This helps active ingredients such as peppermint to act more effectively on the skin surface.

[0063] Enhanced comfort: Hydrophobic nonwoven fabrics usually have a smooth surface and moderate thickness, which can reduce friction and irritation to the skin. This layered setting makes the mask softer and more comfortable as a whole, suitable for long-term wear.

[0064] (3) Optimize the cleansing and makeup removal effects of facial masks

[0065] Cleansing effect of the hydrophilic layer: Hydrophilic nonwoven fabrics can absorb dirt and excess oil on the skin surface, helping to clean the skin. This is important for keeping the skin fresh and clean.

[0066] The isolation effect of the hydrophobic layer: The hydrophobic non-woven fabric can prevent dirt and oil from penetrating into the skin again, thereby enhancing the makeup removal effect of the mask. This is especially suitable for skin that needs makeup removal or deep cleansing.

[0067] (4) Improve the durability and stability of the mask

[0068] Structural reinforcement: The layering of hydrophilic and hydrophobic nonwovens can enhance the overall structural strength of the mask, making it more durable. This helps the mask maintain integrity during transportation, storage and use, and avoid breakage or deformation.

[0069] Improved stability: Through the hot pressing composite process, the hydrophilic nonwoven fabric and the hydrophobic nonwoven fabric can be firmly combined together to form a stable mask substrate. This helps to maintain the shape and size stability of the mask during use, thereby improving the skin care effect.

[0070] In some embodiments, the hot pressing composite comprises the following parameters: hot pressing temperature is 80-150° C., hot pressing pressure is 1-5 MPa, and hot pressing time is 1-5 min.

[0071] In some embodiments, before the hot-pressing lamination, the stacked multi-layer non-woven fabrics are immersed in a low eutectic solvent, and after the hot-pressing lamination, they are washed to remove the low eutectic solvent.

[0072] A deep eutectic solvent is a low eutectic mixture formed by hydrogen bond acceptors and hydrogen bond donors under certain conditions, and has physical and chemical properties similar to those of ionic liquids. A deep eutectic solvent can dissolve many polar substances and can be used as a reaction medium to promote organic reactions. In membrane material processing, a deep eutectic solvent can be used to improve the surface wettability of materials, enhance the mechanical properties of materials, and realize special functionalization of materials.

[0073] In some embodiments, the deep eutectic solvent is betaine and malic acid.

[0074] S5, immersing the facial mask base material in the pepperin solution, and then drying to obtain the pepperin composite facial mask cloth.

[0075] In some embodiments, the pepper liquid is composed of the following chemical components, measured by mass: 1 to 5 parts of pepper, 60 to 80 parts of ethanol, 10 to 20 parts of glycerol, 5 to 15 parts of propylene glycol, 0.1 to 1 part of sodium ascorbate, 0.1 to 1 part of menthol, and 0.1 to 5 parts of phosphate buffer.

[0076] The effects of the various components in the pepper solution are as follows:

[0077] Zanthoxylum bungeanum: As the main active ingredient of the facial mask, Zanthoxylum bungeanum has multiple biological activities, such as anti-inflammatory and antioxidant, and has a good care effect on the skin.

[0078] Ethanol: As a solvent, ethanol can fully dissolve peppermint and help promote the penetration of the essence. At the same time, ethanol also has a certain bactericidal effect, which helps to improve the safety of the product.

[0079] Glycerin: As a humectant, glycerin attracts and retains moisture in the skin, enhancing the moisturizing effect of the mask.

[0080] Propylene glycol: As a co-solvent, propylene glycol can enhance the solubility of peppermint in ethanol and also help promote the penetration of the essence.

[0081] Phosphate buffer: As a pH regulator, phosphate buffer can stabilize the pH value of the pepper solution and prevent it from changing during use, thereby ensuring the stability and safety of the product. The pH of the pepper solution is adjusted to 4.5-6.5 by phosphate buffer.

[0082] Sodium ascorbate: In order to improve the stability of pepper liquid, an appropriate amount of antioxidant can be added. Sodium ascorbate can prevent pepper from oxidative decomposition during storage and use, thereby extending the shelf life of the product.

[0083] Menthol: Menthol acts as a penetration enhancer to lower the skin barrier and promote the penetration and absorption of peppermint and other active ingredients.

[0084] Based on a general inventive concept, the present application provides a peppermint composite facial mask cloth prepared by the preparation method of the peppermint composite facial mask cloth described in any one of the above embodiments, wherein the peppermint composite facial mask cloth comprises a hydrophilic non-woven fabric and a hydrophobic non-woven fabric that are stacked.

[0085] In some embodiments, the hydrophilic non-woven fabric is disposed on both outer sides of the xanthoxylum composite facial mask fabric.

[0086] In some embodiments, the thickness of the Zanthoxylum bungeanum composite facial mask cloth is 0.15 to 0.25 mm.

[0087] In some embodiments, the number of layers of non-woven fabric in the Xanthoxylum bungeanum composite facial mask fabric is 5 to 9 layers.

[0088] The composite mask cloth of pepper extract includes a layered hydrophilic non-woven fabric and a hydrophobic non-woven fabric, which has the following effects on the absorption of pepper extract:

[0089] (1) Improve absorption efficiency: Hydrophilic nonwoven fabrics have good moisture absorption and air permeability, and can quickly absorb and transfer water and other liquid components, including pepper solution. Hydrophobic nonwoven fabrics have waterproof and moisture-proof properties, and can form a protective barrier to prevent pepper solution from penetrating or leaking too quickly. When hydrophilic nonwoven fabrics are stacked with hydrophobic nonwoven fabrics, the hydrophilic layer can efficiently absorb pepper solution, while the hydrophobic layer can slow down its penetration rate, allowing pepper solution more time to diffuse and evenly distribute in the hydrophilic layer, thereby improving absorption efficiency.

[0090] (2) Enhanced durability: The waterproof properties of the hydrophobic nonwoven fabric help prevent the pepper liquid from evaporating or escaping too quickly during mask use. This means that the pepper can remain on the mask substrate for a longer period of time, providing users with a longer-lasting skin care effect.

[0091] (3) Optimizing skin touch: The softness and breathability of the hydrophilic non-woven fabric can ensure a good fit between the mask and the skin. At the same time, the smooth surface of the hydrophobic non-woven fabric can reduce friction and irritation to the skin, improving comfort. This layered setting not only helps the absorption of peppermint, but also provides users with a more pleasant skin care experience.

[0092] (4) Improved permeability: Multi-layer mask cloth can simulate the natural structure of the skin by combining hydrophilic and hydrophobic layers, creating a more favorable permeation environment. The hydrophilic layer helps to retain the skin's moisture, while the hydrophobic layer can reduce excessive water loss and may promote the entry of the active ingredient of pepper into the skin through specific channels or carriers.

[0093] In the embodiments of the present application, the number of layers of non-woven fabric in the composite mask cloth of pepper is limited to 5 to 9 layers. The multi-layered structure helps to form a small pressure difference, which promotes the active ingredients in the essence to better penetrate into the deep layers of the skin. Active ingredients such as pepper can be more evenly distributed in the mask cloth with a multi-layered structure, improving the skin care effect. At the same time, the multi-layered mask cloth can better adapt to the facial contour, reduce the generation of bubbles and gaps, improve the fit, and help ensure that the essence can be evenly distributed on the facial skin to avoid local dryness or over-moisturizing.

[0094] The present application will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are intended only to illustrate the present application and are not intended to limit the scope of the present application. The experimental methods for which specific conditions are not specified in the following examples are usually measured according to industry standards.

[0179] The moisturizing performance, absorption rate of pepper and use experience of the pepper composite mask cloths of Examples 1 to 3 and Comparative Examples 1 to 6 were measured. The specific measurement methods and results are as follows:

[0180] The moisturizing performance of the mask is measured by its evaporation rate. The greater the evaporation rate, the worse the moisturizing performance of the mask; conversely, the better the moisturizing performance of the mask. The evaporation rates of the pepper compound mask fabrics of Examples 1 to 3 and Comparative Examples 1 to 6 were tested using the following method. (1) Remove the packaging of the pepper compound mask cloth, put it in an oven, dry it at 80℃ to constant weight, then put it in a glass desiccator to cool to room temperature, and quickly weigh it, which is recorded as m0 (g); (2) Put the weighed mask sample into a container, then inject 50mL of distilled water into the container, let it stand for 1min, wait until the mask is saturated with liquid, take out the mask, centrifuge it at a speed of 500r / min for 1min, ensure that the liquid in the mask will not drip freely after taking it out, then weigh it, and record it as M (g); (3) Spread the weighed wet mask on a constant temperature water bag at 37℃, after applying it for a certain period of time, peel the sample off the water bag and weigh it, which is recorded as mt (g); (4) Continue to apply the weighed wet sample on the water bag, and repeat the above operation. According to the formula F (%) = (M-mf) / (M-m0) × 100, the evaporation rate F of the mask sample at different application times is calculated. Five samples of each sample are tested and the average value is taken.

[0181] The above method was used to test the evaporation rates of the Zanthoxylum bungeanum composite facial mask fabrics of Examples 1 to 3 and Comparative Examples 1 to 6. The results are shown in Table 1.

[0182] Table 1 Evaporation rate of the pepper compound facial mask cloth of Examples 1 to 3 and Comparative Examples 1 to 6

[0183] Group Evaporation rate in 5 minutes, % Evaporation rate in 10 minutes, % Evaporation rate in 30 minutes, % Evaporation rate in 60 minutes, % Example 1 5.4 12.3 35.7 43.5 Example 2 6.1 14.5 40.1 44.7 Example 3 7.3 15.7 41.5 44.2 Comparative Example 1 10.5 25.6 54.3 55.2 Comparative Example 2 30.2 55.2 98.2 100 Comparative Example 3 9.5 19.6 48.7 50.7 Comparative Example 4 8.9 16.8 46.9 51.7 Comparative Example 5 11.9 22.3 48.5 54.9 Comparative Example 6 7.9 15.8 45.5 48.9

[0184] It can be seen from Table 1 that the evaporation rate of the Zanthoxylum composite mask cloth of Examples 1 to 3 is ≤7.5% in 5 minutes and ≤45% in 60 minutes. The Zanthoxylum composite mask cloth of Examples 1 to 3, the hydrophilic non-woven fabric can quickly absorb and lock moisture to maintain the moisture of the mask, and the hydrophobic non-woven fabric can form a protective barrier to prevent moisture from evaporating too quickly, thereby prolonging the moisturizing effect of the mask.

[0185] The absorption rate of pepper in the pepper composite mask cloth was determined by the following method, using a Franz transdermal absorption diffusion cell to determine the transdermal absorption rate, and the commercially available fragrant pig skin was fixed between the upper and lower chambers of the Franz transdermal absorption diffusion cell, with the stratum corneum facing upward. The pepper composite mask cloths of Examples 1 to 3 and Comparative Examples 1 to 6 were removed from the packaging, and then 50 mL of distilled water was injected into the container, and allowed to stand for 1 min. When the mask was saturated with liquid, the mask was taken out and centrifuged at a speed of 500 r / min for 1 min to ensure that the liquid in the mask would not drip freely after being taken out, and the obtained pepper mask was covered on the fragrant pig skin. The test was carried out using the RT800 automatic sampling transdermal diffusion system. Physiological saline was placed in the receiving pool so that the receiving solution was in contact with the dermis. Then 100 μL was taken at 10 min, 20 min, 30 min and 40 min respectively. The concentration of anthoxanthin in the receiving solution was detected by HPLC-MS, and the transdermal absorption amount was calculated. The transdermal absorption rate was calculated according to the following formula: Transdermal absorption rate (%) = (transdermal absorption amount / initial dose) × 100.

[0186] The above method was used to test the absorption rate of the peppermint in the peppermint composite facial mask fabrics of Examples 1 to 3 and Comparative Examples 1 to 6. The results are shown in Table 2.

[0187] Table 2 Absorption rate of peppermint in peppermint composite mask cloth of Examples 1 to 3 and Comparative Examples 1 to 6

[0188] Group 10min transdermal absorption rate, % 20min transdermal absorption rate, % 30min transdermal absorption rate, % 40min transdermal absorption rate, % Example 1 3.365 6.987 8.214 10.657 Example 2 3.122 6.421 7.912 9.954 Example 3 2.984 6.124 7.745 9.914 Comparative Example 1 5.612 6.784 7.184 8.914 Comparative Example 2 1.125 2.021 3.024 4.457 Comparative Example 3 4.412 6.614 6.978 7.254 Comparative Example 4 2.774 5.984 6.545 8.887 Comparative Example 5 2.814 6.001 7.704 9.004 Comparative Example 6 2.967 6.024 7.454 8.989

[0189] As shown in Table 2, in the composite mask cloth of pepper extract in Examples 1 to 3, the transdermal absorption rate in the first 10 minutes is relatively weak, but as time goes by, the transdermal absorption rate gradually increases, showing a sustained release effect, and the final transdermal absorption rate is greater than that of the comparative example, and the transdermal absorption rate of the composite mask cloth of pepper extract in Examples 1 to 3 is greater than 9.5% at 40 minutes. It can be seen that in the embodiment, when the hydrophilic non-woven fabric and the hydrophobic non-woven fabric are stacked, the hydrophilic layer can efficiently absorb the pepper extract solution, while the hydrophobic layer can slow down its penetration rate, so that pepper extract has more time to diffuse and evenly distribute in the hydrophilic layer, thereby improving the absorption efficiency.

[0190] The following method was used to test the performance of the pepper composite mask cloth of Example 1: 50 mL of drinking water was injected into the mask packaging bag, and the mask was left to stand for 1 min. When the mask was saturated with liquid, the mask was taken out and applied to the face of the user. After applying for a certain period of time, a skin moisture tester was used to test the moisture content of the user's skin after applying the mask. In addition, the user comprehensively evaluated the performance of the mask from the aspects of the hydration, fullness, smoothness, moisturization, conformability and comfort of the skin after use. The full score is 10 points, and the higher the score, the better the experience performance.
