Description

Technical Field

[0001] The present invention belongs to the technical field of cosmetics, and in particular relates to a highly moisturizing and soothing facial mask liquid and a preparation method thereof. Background Art

[0002] A facial mask is a beauty product that achieves skincare benefits by soaking a specific carrier, such as a cloth, patch, or paste, in a mask solution and applying it to the face to create a closed or semi-closed environment. Regardless of the carrier's form, the value of most facial masks, i.e., the level of their skincare efficacy, is directly dependent on the formulation of the mask solution. While a large number of moisturizing masks are currently available on the market, these masks still have certain drawbacks that limit their practical application. This is because, on the one hand, these masks often have a single ingredient, essentially relying on a single component such as glycerin or hyaluronic acid for immediate hydration, failing to meet consumers' demand for sustained moisturization. On the other hand, with the increasing complexity and pace of modern life, facial skin problems are becoming increasingly severe, with the number of people suffering from adverse symptoms such as redness, itching, and stinging increasing year by year. However, most of these moisturizing masks struggle to also provide soothing benefits, failing to effectively repair and soothe facial skin that has already developed these symptoms. Summary of the Invention

[0003] In response to the problems existing in the prior art, the purpose of the present invention is to provide a highly moisturizing and soothing facial mask liquid and a preparation method thereof. The present invention uses moisturizers, soothing agents, chelating agents, thickeners, penetration enhancers, surfactants, preservatives and deionized water as raw materials to prepare a highly moisturizing and soothing facial mask liquid, which not only has excellent moisturizing function and achieves the purpose of continuous moisturizing, but also has a good soothing effect and effectively exerts a repairing effect. Among them, the moisturizers include glycerin, sodium polyglutamate, polyethylene glycol-400 and yeast / rice fermentation product filtrate, and the soothing agents include shiitake mushroom extract obtained by enzymatic hydrolysis of shiitake mushrooms with cellulase, pectinase and flavor protease, jujube leaf extract obtained by water extraction of jujube leaves and raspberry extract obtained by water extraction of raspberries. The remaining raw materials are all conventionally selected.

[0004] The purpose of the present invention can be achieved through the following technical solutions:

[0005] In a first aspect, a highly moisturizing and soothing facial mask liquid comprises the following components in weight percentage: 5-15% moisturizer, 0.5-3% soothing agent, 0.04-0.07% chelating agent, 0.2-0.4% thickener, 0.5-0.8% penetration enhancer, 0.2-0.4% surfactant, 0.1-0.3% preservative and the balance deionized water.

[0006] Furthermore, the moisturizing agent comprises 10-12 parts by weight of glycerin, 2-4 parts by weight of sodium polyglutamate, 1 part by weight of polyethylene glycol-400 and 2-4 parts by weight of yeast / rice fermentation product filtrate.

[0007] Furthermore, the soothing agent comprises 20-30 parts by weight of Lentinus edodes extract, 5 parts by weight of jujube leaf extract and 5-7 parts by weight of raspberry extract.

[0008] Preferably, the shiitake mushroom extract is prepared by the following steps:

[0009] Step A: crushing the mushrooms and sieving to obtain crushed mushroom material;

[0010] Step B: Mix the crushed mushroom material and deionized water at a mass ratio of 1:10-12 at room temperature for 5-10 minutes, add cellulase, pectinase and flavor protease, and then enzymatically hydrolyze at 40-55°C for 2-3 hours, inactivate the enzyme, filter, collect the filtrate, and dry it.

[0011] More preferably, the sieving in step A refers to sieving through a 100-mesh sieve.

[0012] More preferably, in step B, the mass ratio of the crushed mushroom material, the cellulase, the pectinase and the flavor protease is 100:0.3-0.5:0.3-0.4:0.8-1.

[0013] More preferably, the enzyme inactivation in step B is to raise the temperature to 95°C at a heating rate of 2-4°C / min and then maintain the temperature for 10-15 minutes.

[0014] More preferably, the drying in step B refers to vacuum freeze drying to constant weight at a temperature of -40°C and a pressure of 4-6 Pa.

[0015] Furthermore, the chelating agent is disodium EDTA.

[0016] Furthermore, the thickener is at least one of xanthan gum and carbomer.

[0017] Furthermore, the penetration enhancer is laurocapram.

[0018] Furthermore, the surfactant is polysorbate-80.

[0019] Furthermore, the preservative comprises 10-15 parts by weight of phenoxyethanol and 3-3.5 parts by weight of ethylhexylglycerin.

[0020] In a second aspect, a method for preparing a highly moisturizing and soothing facial mask liquid is provided, the method comprising the following steps:

[0021] Add moisturizer, soothing agent, chelating agent and thickener to deionized water, then stir and mix at 50-60°C for 20-30 minutes, then add penetration enhancer and surfactant, stir and mix at constant temperature for 15-20 minutes, finally add preservative, continue stirring at constant temperature for 10-15 minutes, and cool naturally to room temperature.

[0022] Beneficial effects of the present invention:

[0023] 1. The present invention uses moisturizing agents, soothing agents, chelating agents, thickeners, penetration enhancers, surfactants, preservatives and deionized water as raw materials to prepare a highly moisturizing and soothing facial mask liquid, which not only has excellent moisturizing function and achieves the purpose of continuous moisturizing, but also has a good soothing effect and effectively exerts a repairing effect. Among them, the moisturizing agents include glycerin, sodium polyglutamate, polyethylene glycol-400 and yeast / rice fermentation product filtrate, and the soothing agents include shiitake mushroom extract obtained by enzymatic hydrolysis of shiitake mushrooms with cellulase, pectinase and flavor protease, jujube leaf extract obtained by water extraction of jujube leaves and raspberry extract obtained by water extraction of raspberries. The remaining raw materials are all conventionally selected.

[0024] 2. Most of the existing facial mask liquids contain glycerin, which is a common moisturizing ingredient. It can not only penetrate into the stratum corneum, improve skin texture, and reduce water evaporation, but also activate aquaporins and maintain skin hydration. Even so, it is difficult to achieve continuous moisturizing of the skin by relying solely on glycerin, and there are still certain defects. On this basis, the present invention adds sodium polyglutamate, polyethylene glycol-400 and yeast / rice fermentation product filtrate. The above three components produce an excellent synergistic effect with glycerin, giving the facial mask liquid of the present invention an excellent moisturizing function and achieving continuous moisturizing of the skin. Sodium polyglutamate is a polyglutamic acid and sodium ion The combination product of polyols and PEG-400 has good water solubility, and a large number of hydrophilic groups can absorb moisture well, bringing lasting hydration effect to the skin. Polyethylene glycol-400, as a product connected by multiple ether bonds, can also absorb moisture from the air to achieve the purpose of locking in moisture. At the same time, sodium polyglutamate and polyethylene glycol-400 themselves have certain film-forming properties. Through interactions such as hydrogen bonds, the two can form a strong moisturizing network structure and reduce the rate of water loss. The yeast / rice fermentation product filtrate is rich in a variety of natural moisturizing factors. Its addition can further prolong the skin's moisturizing and hydrating effects and promote continuous and lasting moisturizing of the skin.

[0025] 3. The facial mask liquid of the present invention also adds a soothing agent, which includes shiitake mushroom extract, jujube leaf extract and raspberry extract. Shiitake mushroom extract contains a variety of active ingredients such as sugars and peptides, which can show excellent anti-inflammatory properties and relieve skin inflammation. Jujube leaf extract is rich in flavonoids and terpenoids, which can play a good inhibitory role in the expression of pro-inflammatory factors and reduce the occurrence of inflammatory reactions. Raspberry extract, as a fruit extract, contains a large amount of phenolic acids, which has a certain promoting effect on the renewal of skin cells and the repair of the barrier. The excellent synergistic effect produced by the above three extracts at multiple levels makes the facial mask liquid of the present invention have an excellent soothing effect in addition to its excellent moisturizing function. In particular, shiitake mushroom The extract is obtained by enzymatic hydrolysis with cellulase, pectinase and flavor protease, and the jujube leaf extract and raspberry extract are obtained by water extraction. Although water extraction has more advantages in cost, the inventors found that if all three extracts are obtained by water extraction, the soothing effect of the facial mask liquid still needs to be improved. On this basis, considering the cost and source issues, the inventors tried to use a composite enzyme to enzymatically extract shiitake mushrooms, and finally improved the soothing effect of the facial mask liquid. The possible reason is that the shiitake mushroom extract obtained by enzymatic hydrolysis reduces some potential antagonistic effects with other extracts, thereby amplifying the soothing effect. At the same time, the enzymatic hydrolysis treatment of the composite enzyme also enriches the types of active ingredients, that is, the diversity of the enzymatic hydrolysis products is improved, which also plays a certain role in promoting the soothing effect.

[0106] 1. Moisturizing test:

[0107] The test steps are as follows:

[0108] Step A: Soak the pure cotton mask cloth completely in the highly moisturizing and soothing mask solution prepared in Example 3 and Comparative Examples 1-12 for 30 minutes, take it out, and obtain 13 different test masks, wherein the weight of the pure cotton mask cloth is 40g / m 2 , each piece of pure cotton mask cloth is soaked in 25g of highly moisturizing and soothing mask liquid.

[0109] Step B: 195 subjects aged 20-40 were randomly divided into 13 groups. The facial skin of each subject was then washed with clean water and the surface moisture was absorbed with cotton. The moisture content of the facial skin of each subject was then tested using a skin moisture tester. The mean moisture content of each group was calculated and recorded as M1.

[0110] Step C: Each group of subjects applied a test mask for 20 minutes, removed the test mask, and retested the moisture content of each subject's facial skin using a skin moisture tester 8 hours later. The mean moisture content of each group was calculated, that is, the moisture content growth rate was obtained, recorded as M2. The skin location for each moisture content test remained consistent. The subjects remained in an environment with a temperature of 25±0.5℃ and a relative humidity of 50±1% until the end of all tests. No washing was performed within 8 hours after removing the test mask.

[0111] Table 1 Test results of moisturizing test

[0112] M1 / average moisture content% M2 / growth rate % Example 3 26.8 32.6 Comparative Example 1 28.0 5.1 Comparative Example 2 26.3 16.8 Comparative Example 3 27.5 24.0 Comparative Example 4 28.4 21.7 Comparative Example 5 27.9 30.5 Comparative Example 6 26.6 31.1 Comparative Example 7 27.3 30.1 Comparative Example 8 26.3 29.9 Comparative Example 9 25.9 30.8 Comparative Example 10 27.8 31.4 Comparative Example 11 27.0 28.8 Comparative Example 12 26.1 31.5

[0113] As can be seen from Table 1, the facial mask liquid prepared by Example 3 of the present invention has excellent moisturizing function and good continuous moisturizing effect. Compared with Example 3 of the present invention, the growth rate of Comparative Example 1 after replacing the moisturizer with glycerin is very small, and it is difficult to exert the continuous moisturizing effect. The growth rates of Comparative Examples 2-4 after replacing the components in the moisturizer except glycerin are also reduced. Although the soothing agent in Comparative Example 11 is replaced with deionized water, its growth rate is only slightly reduced, and the degree of reduction is far less than that of Comparative Examples 2-4. As for Comparative Examples 5-10 and Comparative Example 12, the decrease in growth rate is very small, and it can be approximately considered that there is no significant impact on the continuous moisturizing effect.

[0114] 2. Relief test:

[0115] The test steps are as follows:

[0116] Step A: Recruit 350 subjects aged 20-40 years who subjectively considered themselves to have sensitive skin (the subjects' skin was still healthy and did not show any adverse symptoms). Then wash the back skin of each subject with clean water, dry the surface moisture with cotton, divide the test area into 2cm*2cm in size, and then use tape to stick the test area, press for 2s and then peel it off. Repeat this sticking-peeling process 5 times and then apply 0.5mL of 1g / L capsaicin solution (the solvent is 20% ethanol aqueous solution by mass). After 2 minutes, use cotton to dry the surface moisture. The subjects score their subjective discomfort on a scale of 0-10. The larger the score, the more severe the subjective discomfort. 0 means no subjective discomfort. The score is rounded to the nearest integer. The final score results are: 4 points for 12 people, 5 points for 23 people, 6 points for 28 people, 7 points for 39 people, 8 points for 40 people, 9 points for 175 people, and 10 points for 33 people.

[0117] Step B: 168 people were randomly selected from the 175 people with a score of 9 and randomly divided into 14 groups. The test areas of each group of subjects were smeared with the highly moisturizing soothing mask liquid prepared in Example 3 and Comparative Examples 1-12, and the smearing amount was 1 g. The remaining group was the control group, and 1 g of deionized water was applied. After 25 minutes, each subject scored the subjective discomfort again. The scoring criteria were the same as in step A, and the mean score of each group was calculated.

[0118] Table 2 Test results of the soothing test

[0119]

[0120]

[0121] As can be seen from Table 2, the facial mask liquid prepared by Example 3 of the present invention has excellent soothing function and can effectively play a repairing role. Compared with Example 3 of the present invention, the score of Comparative Example 1 is increased after the moisturizer is replaced by glycerin, but the increase is not large. Combined with Comparative Examples 2-4, the increase in Comparative Examples 2-4 is even smaller, indicating that the effect of the moisturizer on the soothing function is not very obvious. The scores of Comparative Examples 5-10 are obviously improved, but the soothing function is limited. After the soothing agent is replaced by deionized water in Comparative Example 11, its soothing effect is slightly better than that of the control group. As for Comparative Example 12, after the shiitake mushroom extract is replaced by commercially available shiitake mushroom extract, that is, replaced by shiitake mushroom extract obtained by water extraction, its soothing function is also significantly reduced.

[0122] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principles of the present invention should be considered as equivalent replacement methods and are included in the scope of protection of the present invention.
