[0046] Example 1 Preparation of Chinese herbal medicine extracts

[0047] 1. Pretreatment of Chinese medicine materials

[0048] 1) Material selection and cleaning:

[0049] Select the medicinal materials that meet the standards from the high-quality Chinese medicinal materials, clean them, remove impurities, mud and bad medicinal materials (to ensure the purity of the raw materials during the extraction process), and obtain astragalus, ganoderma lucidum, licorice, lily, ginseng and codonopsis.

[0050] 2) Slicing and crushing:

[0051] The cleaned medicinal materials are sliced ​​or crushed (to increase their surface area, which is beneficial for the subsequent extraction step), and the particle size of the crushed Chinese medicinal materials is controlled at 1-2mm (to facilitate uniform heating and release of active ingredients).

[0052] 2. Extraction method

[0053] Low-temperature freeze-drying technology is an advanced method of extracting traditional Chinese medicine. It freezes the water in the medicinal materials quickly at low temperatures and then sublimates and dries them under vacuum. This technology can retain the effective ingredients of traditional Chinese medicines to the greatest extent and avoid the damage of active substances by high temperatures. The specific steps are as follows:

[0054] 1) Pretreatment and low temperature freezing:

[0055] The pre-treated Chinese medicinal materials are placed in a freezing device, the temperature is gradually lowered to -50°C, and then cooled to -80°C to completely freeze the water in the medicinal materials to obtain frozen medicinal materials. The low-temperature freezing time is about 4-6 hours (the low-temperature freezing time in this embodiment is controlled at 5 hours) to ensure that all the water is frozen and the medicinal materials do not suffer structural damage.

[0056] 2) Vacuum drying sublimation:

[0057] The frozen medicinal materials are placed in a vacuum drying device, the pressure is reduced to 5-50 Pa (the pressure in this embodiment is controlled at 25 Pa), and the temperature is slowly raised to 20°C, and then to 30°C, so that the ice crystals in the medicinal materials are directly sublimated into water vapor without passing through liquid water, thereby removing the moisture. The vacuum drying sublimation time is controlled at 12-24h (the vacuum drying sublimation time in this embodiment is controlled at 18h), and the specific time is determined according to the moisture content and type of the medicinal materials, ensuring that the moisture in the medicinal materials is completely removed, and the effective ingredients are not damaged by high temperature.

[0058] 3) Powderization after vacuum drying and sublimation:

[0059] The vacuum dried and sublimated medicinal materials are crushed to obtain ultrafine powder, and the powder particle size is controlled between 50-150μm (to ensure the efficiency and stability of the subsequent extraction process).

[0060] 3. Solvent selection and extraction time control during the extraction process

[0061] Select a suitable solvent for extraction from the low-temperature freeze-dried Chinese herbal medicine powder. Generally, water or ethanol is selected as the solvent, and different extraction processes are performed according to different Chinese herbal medicine components.

[0062] 1) Water extraction method:

[0063] The effective components of astragalus, ganoderma lucidum, liquorice and lily (such as astragalus polysaccharide, ganoderma lucidum polysaccharide, glycyrrhizic acid, etc.) can be dissolved in water, so astragalus, ganoderma lucidum, liquorice and lily are subjected to water extraction.

[0064] Astragalus, Ganoderma lucidum, Licorice and Lilium are extracted with water respectively, and the steps of water extraction are as follows:

[0065] The astragalus, ganoderma, licorice, lily and water after vacuum drying and sublimation are mixed in a ratio of 1 g: 10 mL, respectively, and extracted for 2-4 h (the extraction time in this embodiment is controlled at 3 h to ensure the full release of the active ingredients in the medicinal materials), the water temperature is controlled at 70°C-90°C (the temperature in this embodiment is controlled at 80°C to avoid high temperature damage to the active ingredients), and the extraction is performed 2-3 times (the number of extractions in this embodiment is controlled at 2 times), and then the extract is filtered, centrifuged (to remove impurities) and vacuum concentrated to 1 / 10-1 / 20 of the original volume (to increase the concentration of the active ingredients and facilitate subsequent nano-microencapsulation treatment), and finally the astragalus extract, ganoderma extract, licorice extract and lily extract are obtained.

[0066] 2) Ethanol extraction method:

[0067] For medicinal materials with more fat-soluble components (such as ginseng and salvia miltiorrhiza), ethanol extraction is more effective, so ginseng and salvia miltiorrhiza were extracted with ethanol.

[0068] The ginseng and salvia miltiorrhiza after vacuum drying and sublimation are mixed with 30%-70% ethanol solution (the volume percentage of ethanol in the ethanol solution used in this embodiment is 50%) in a solid-liquid ratio of 1g:10mL, extracted for 2-3h (the extraction time in this embodiment is controlled at 2.5h), the extraction temperature is controlled at 40℃-60℃ (the extraction temperature in this embodiment is controlled at 50℃) to completely extract the fat-soluble components, extracted 2-3 times (the number of extractions in this embodiment is controlled at 3 times), and then the extract is filtered, centrifuged (to remove impurities) and vacuum concentrated to 1 / 10-1 / 20 of the original volume (to increase the concentration of the active ingredient and facilitate subsequent nano-microencapsulation treatment), and finally ginseng extract and codonopsis pilosula extract are obtained.

[0069] 4. Active ingredient concentration and adjustment ratio of each Chinese herbal medicine extract

[0070] According to the efficacy of different Chinese herbal ingredients, the present invention optimizes the effect of each ingredient in the formula by adjusting the concentration and ratio of the active ingredients of the extracts. The following is a description of the concentration and adjustment ratio of the active ingredients of each Chinese herbal extract:

[0071] 1) Astragalus extract:

[0072] The active ingredients of the astragalus extract are astragalus polysaccharide and saponin, and the concentration of astragalus polysaccharide is between 30% and 40%. The use ratio of the astragalus extract is between 5wt.% and 10wt.%, and it is mainly used to enhance the skin's immune function, protect the skin barrier, and enhance the antioxidant capacity.

[0073] 2) Ganoderma lucidum extract:

[0074] The active ingredient of the ganoderma lucidum extract is ganoderma lucidum polysaccharide, and the polysaccharide content in the extract is controlled at 50%-60%. The use ratio of the ganoderma lucidum extract is between 3wt.%-8wt.%, and it is mainly used to regulate the immune system, anti-oxidation and anti-inflammation.

[0075] 3) Salvia miltiorrhiza extract:

[0076] The effective components of the Danshen extract are tanshinone and salvianolic acid, and the concentration of salvianolic acid is 20%-30%. The use ratio of the Danshen extract is between 2wt.% and 6wt.%, which is helpful to promote blood circulation and remove blood stasis and promote skin metabolism.

[0077] 4) Lily Extract:

[0078] The active ingredients of lily extract are various alkaloids with a concentration of 15%-20%. The usage ratio of lily extract is between 1wt.%-5wt.%, which is used to nourish yin and moisturize the skin and improve dry skin.

[0079] 5) Licorice Extract:

[0080] The active ingredient of the licorice extract is glycyrrhizic acid, and the concentration of glycyrrhizic acid is 10%-15%. The use ratio of the licorice extract is between 2wt.% and 4wt.%, which has anti-inflammatory and anti-allergic effects and can soothe the skin.

[0081] 6) Ginseng Extract:

[0082] The active ingredient of ginseng extract is ginsenoside, with a concentration of 5%-10%. The usage ratio of ginseng extract is between 1wt.%-3wt.%, which has the effects of anti-aging and improving skin elasticity.

[0083] The Chinese herbal medicine ingredients extracted by low-temperature freeze-drying technology can maintain their active ingredients, and after scientific regulation, the concentration and proportion of the extracts are adjusted according to different efficacy requirements to ensure that the mask can play the best immune enhancement, anti-aging, repair and moisturizing effects. This extraction method can not only effectively extract the active ingredients in Chinese herbal medicines, but also maximize their efficacy, ensuring the innovation and operability of the product.

[0084] The Chinese herbal extract prepared in this example was used in subsequent experiments.

[0085] Example 2

[0096] Panthenol: 0.2wt.%–1wt.%.

[0097] 3. Mask base

[0098] The mask matrix can be made of hydrogel matrix or non-woven fabric to ensure good air permeability, high softness, and close fit to the skin, so as to help the effective ingredients of traditional Chinese medicine to better penetrate the skin and exert their effects. In this embodiment, the hydrogel matrix is ​​selected: 70wt.%-90wt.%.

[0099] The mass ratio of carbomer, glycerin and sodium hyaluronate in the hydrogel matrix is ​​1:1:1. Among them, carbomer, as the main component of the gel, has excellent film-forming properties and softness, ensuring that the mask fits tightly on the skin; sodium hyaluronate can absorb and store a large amount of water, forming a hydration film on the skin surface for sufficient moisturizing; glycerin can improve the moisturizing effect of the mask and help the hydrogel maintain appropriate viscosity.

[0100] Preparation process of hydrogel matrix:

[0101] Dissolve carbomer in warm water below 40°C and stir until completely dissolved to form a uniform matrix solution. Slowly add moisturizing ingredients such as sodium hyaluronate and glycerin and continue stirring until the hydrogel matrix is ​​fully formed. Then use a pH adjuster (such as triethanolamine) to adjust the pH value of the solution to between 5.5-6.5 to ensure the mildness of the hydrogel, close to the natural pH of the skin.

[0102] The preparation method of the mask is as follows

[0103] 1). Nano-microencapsulation treatment: Encapsulate the Chinese herbal medicine extract in nano-microcapsules and concentrate them to obtain a concentrated solution of the Chinese herbal medicine extract to ensure that it has good permeability and stability. The specific steps are as follows:

[0104] mixing the Chinese herbal medicine extracts to obtain a Chinese herbal medicine extract mixture;

[0105] The Chinese herbal medicine extract mixture and 2 wt.% sodium alginate solution were mixed in a volume ratio of 1:3 to obtain a capsule solution;

[0106] The capsule solution was added dropwise to a 2wt.% calcium chloride solution and allowed to stand for 10 min to obtain a solution containing wet capsules. The dropping speed was 100 drops / min.

[0107] The solution containing the wet capsule is concentrated to 1 / 10 of the original volume to obtain a concentrated solution of the Chinese herbal medicine extract.

[0108] 2) Active ingredient mixing: Mix the concentrated solution of Chinese herbal extract, sodium hyaluronate (moisturizer) and panthenol (repair ingredient), stir well to obtain the active ingredient.

[0109] 3). Mixing of active ingredients and hydrogel matrix:

[0110] The active ingredients were slowly added to the hydrogel matrix and stirred at a constant speed of 1000 rpm using a high-efficiency stirrer to ensure that the Chinese medicine ingredients and the hydrogel were evenly mixed to form a gel solution with a uniform texture.

[0111] 4). Emulsification and stabilization:

[0112] The gel solution was further emulsified and stabilized by ultrasonic emulsification technology, and ultrasonication was performed at 200W for 5 minutes to ensure that the traditional Chinese medicine and the hydrogel matrix formed a stable emulsion-like mixture to prevent stratification and precipitation.

[0113] How to use the mask:

[0114] The user applies the mask of the present invention to the cleansed face, and gently massages the face with fingertips to allow the mask to cover the face evenly. There is no need to wash it off, and the nutrients in the mask will be gradually absorbed by the skin. It is recommended to use it 2-3 times a week, and the frequency of use can be appropriately increased or decreased according to personal skin conditions and needs.

[0177] Test Example 1

[0178] Moisturizing effect test:

[0179] The measurement conditions were a temperature of 20±2°C and a relative humidity of 50%±3%. 30 women who had not received skin treatment or beauty treatment were selected and divided into 3 groups, each with 10 people. The masks obtained in Example 3 and Comparative Example 1 were used on the face respectively. One group was a blank group, and pure water was applied to the face. The method of use was to evenly apply the mask on the face, keep it for 15 minutes, and then rinse it with clean water. The skin moisture content before use and 30 minutes after use was measured with a skin moisture tester. Each group of samples was tested in parallel 3 times, and the skin hydration growth rate was calculated. The test results are shown in Table 1. The skin hydration growth rate calculation formula is as follows:

[0180] Skin hydration rate increase = (MWVt-MWV0) / MWV0×100%;

[0181] Wherein, MWV0 is the moisture content of the skin before applying the sample, and MWVt is the moisture content of the skin after application for t time.

[0183] deal with 30min hydration rate increase (%) Example 3 97 Comparative Example 1 80 Blank Group 54

[0184] It can be seen from the experimental results in Table 1 that the facial mask obtained in Example 3 has the best moisturizing effect.

[0185] Test Example 2

[0186] Skin barrier repair function test:

[0187] 30 volunteers aged 18-50 were selected, with 10 people in each group. After the skin barrier was damaged by tape stripping on the inner side of the forearm, the masks of Example 4 and Comparative Example 2 were applied respectively, and one mask was tested in each group for 10 minutes. Use once a day for 7 consecutive days. The repair rate of each mask on the skin barrier was evaluated by testing the transepidermal water loss rate 1 day before the experiment, the 3rd day and the 7th day of the experiment. The smaller the value of the transepidermal water loss rate, the better the skin barrier. The test results are shown in Table 2.

[0188] Table 2 Mask repair efficacy test results

[0189]

[0190] The results show that the masks of Example 4 and Comparative Example 2 can both reduce the transepidermal water loss rate of damaged skin. However, in comparison, the transepidermal water loss rate of damaged skin after use of the mask of Example 4 is reduced to the greatest extent, and the skin barrier repair effect of the mask of Comparative Example 2 is reduced after the preparation method of the mask is changed.
