Description

Technical Field

[0001] This invention belongs to the field of cosmetic technology, specifically relating to a soothing and repairing composition and its application. Background Technology

[0002] As we age, the stratum corneum of the skin thins, weakening its protective function. Smoke, dust, UVA and UVB rays, as well as infrared radiation, can all generate free radicals that damage the skin's lipid barrier, thus harming the skin. Stress, mental tension, and low mood can also weaken the skin's natural resistance and reduce its self-repair function. Consumers are using cosmetics more frequently, and the probability of exposure to irritants is increasing accordingly, leading to a growing number of consumers experiencing thinning of the stratum corneum and damage to the skin barrier.

[0003] Currently, the number of people with sensitive skin is increasing daily, and both domestic and international markets are paying more and more attention to products with anti-allergy and repairing effects. Soothing and repairing products on the market often achieve their effects by eliminating alcohol, reducing the amount of preservatives, eliminating fragrances, and adding soothing and repairing ingredients. However, there are relatively few soothing and repairing cosmetics available, and due to individual differences—the causes of allergies vary from person to person—most products are not very effective and often lack immediate soothing and repairing effects.

[0004] As people pay more attention to health and quality of life, consumer demand for soothing and repairing cosmetics will continue to grow. Therefore, developing a gentle product with immediate soothing and repairing effects is one of the hottest research topics in the cosmetics industry. Summary of the Invention

[0033] Example 1 of efficacy test: Hyaluronidase inhibition rate test Hyaluronic acid is widely present in the skin and other tissues, and its relationship with the skin is very close. High-molecular-weight hyaluronic acid can inhibit inflammatory responses, thus alleviating discomfort caused by skin inflammation. However, high-molecular-weight hyaluronic acid is degraded by hyaluronidase, resulting in a decrease in its content and the production of the degradation product N-acetylglucosamine. Therefore, measuring the N-acetylglucosamine content in the reaction system can indirectly reflect the activity of hyaluronidase.

[0034] This embodiment determines the inhibition rate of hyaluronidase by measuring the N-acetylglucosamine content in the reaction system, thereby evaluating the soothing and repairing efficacy of the compositions.

[0035] Test samples: The compositions prepared in Examples 1-3 and Comparative Examples 1-7 were respectively added to an acetate-sodium acetate buffer solution with pH=5.6, mixed evenly, and prepared into a test solution with a concentration of 1.5 v / v%. The specific testing method is as follows: Take four clean test tubes and label them A, B, C, and D respectively. Test tube A is the sample group, test tube B is the sample control group, test tube C is the negative control group, and test tube D is the reagent blank group. Add 50 μL of the sample to be tested to each of test tubes A and B. Add 50 μL of acetate-sodium acetate buffer solution with pH=5.6 to each of test tubes C and D. Add 50 μL of 500 U / mL hyaluronidase solution (prepared with acetate-sodium acetate buffer solution with pH=5.6 as solvent) to each of test tubes A and C. Add 50 μL of acetate-sodium acetate buffer solution with pH=5.6 to each of test tubes B and D. Place the test tubes in a 37℃ incubator for 20 min. Add 10 μL of 2.5 mol / L CaCl2 solution to each of the four test tubes, and then incubate at 37℃ for 20 min. Add 50 μL of 0.5 mg / mL sodium hyaluronate solution (prepared with an acetate-sodium acetate buffer solution at pH 5.6) to test tubes A and C, and add 50 μL of an acetate-sodium acetate buffer solution at pH 5.6 to test tubes B and D. Incubate the test tubes at 37℃ for 40 min, and then let them stand at room temperature for 10 min. Add 50 μL of distilled water, 10 μL of 5 mol / L NaOH solution, and 50 μL of acetylacetone solution to each of the four test tubes, respectively. Place the test tubes in a boiling water bath for 30 min, then in an ice bath for 10 min, and finally let them stand at room temperature for 10 min. Add 100 μL of P-DAB reagent to each test tube, and then measure the absorbance at 530 nm using an ELISA reader. Each group was measured in parallel 3 times. The hyaluronidase inhibition rate was calculated according to the following formula. The data are presented as average values. The calculated data are shown in Table 2 below. ; In the formula: A represents the OD value of the sample group (test tube A); B represents the OD value of the sample control group (tube B). C represents the OD value of the negative control group (C tube); D represents the OD value of the reagent blank group (D test tube); Table 2 Hyaluronidase inhibition rate data Group Hyaluronidase inhibition rate (%) Example 1 85.23 Example 2 86.14 Example 3 88.79 Comparative Example 1 55.07 Comparative Example 2 67.41 Comparative Example 3 59.68 Comparative Example 4 62.80 Comparative Example 5 79.12 Comparative Example 6 74.25 Comparative Example 7 77.46 Example 2 of efficacy test: Inflammatory factor inhibition test TNF-α is the most common inflammatory factor in the inflammatory response. It can induce the phenotype of vascular endothelial cells to become inflammatory, leading to changes in the body's metabolism and hemodynamics, and promoting the production of inflammatory mediators. In turn, inflammatory mediators can increase vascular permeability, resulting in local congestion and edema, and may also stimulate nerve endings, causing skin itching and pain. Therefore, inhibiting TNF-α helps to soothe and repair the skin.

[0036] This efficacy test example evaluates the soothing ability of the compositions by detecting the inhibition rate of TNF-α of the compositions prepared in Examples 1-3 and Comparative Examples 1-7 of this application.

[0037] Sample preparation: The compositions prepared in Examples 1-3 and Comparative Examples 1-7 were diluted with DMEM medium to a concentration of 10 v / v% for the test solution. RAW264.7 cells grown to the logarithmic growth phase were fed with a 1.5 × 10⁻⁶ ppm. 5Cells were seeded at a density of 800 μL / mL in 24-well plates and incubated at 37°C in a 5% CO2 incubator for 24 h. When the cells reached near confluence, 50 μL of the test solution was added to each well of the sample group, 50 μL of 10 μg / mL dexamethasone was added to each well of the positive control group, and 50 μL of DMEM medium was added to each well of the blank control group. Each group had 3 replicates. After 1 h, the cells were stimulated with 1 μg / mL lipopolysaccharide (LPS) and incubated in a cell culture incubator for 24 h. The cell culture medium was then transferred to centrifuge tubes and centrifuged at 5000 rpm for 10 min to collect the cell supernatant. The cells were then detected according to the instructions of the mouse TNF-α enzyme-linked immunosorbent assay kit. The TNF-α inhibition rate is calculated as follows: ; In the formula: X 空白对照组 The TNF-α content of the blank control group; X 阳性对照组 The TNF-α content in the positive control group; X 样品组 The TNF-α content of the sample group is shown; each group was measured in triplicate, and the data are presented as the average value. The calculated data are shown in Table 3 below; Table 3 TNF-α inhibition rate data Group TNF-α inhibition rate (%) Blank control group 0.00 Example 1 82.79 Example 2 81.25 Example 3 84.63 Comparative Example 1 54.91 Comparative Example 2 67.32 Comparative Example 3 58.60 Comparative Example 4 64.57 Comparative Example 5 73.26 Comparative Example 6 77.08 Comparative Example 7 75.64 Compared with Example 3, Comparative Examples 1-4 did not contain one of the following: Stephania tetrandra extract, Date palmatum fruit extract, Sophora flavescens flower extract, and Mirabilis jalapa extract. Comparative Examples 5-7 had mass ratios of Stephania tetrandra extract, Date palmatum fruit extract, Sophora flavescens flower extract, and Mirabilis jalapa extract that were not within the range specified in this invention.

[0038] As shown in Tables 2-3, the data on hyaluronidase inhibition rate and TNF-α inhibition rate of Example 3 and Comparative Examples 1-4 indicate that Example 3, which uses a combination of four components—Stephania tetrandra extract, jujube fruit extract, Sophora flavescens flower extract, and Mirabilis jalapa extract—has a high hyaluronidase inhibition rate and TNF-α inhibition rate. This suggests that the four components have a synergistic effect, which improves the soothing and repairing effect of the composition.

[0039] Based on the data from Examples 1-3 and Comparative Examples 5-7 in Tables 2-3, it can be seen that when the mass ratio of Stephania tetrandra extract, Date palm fruit extract, Sophora flavescens flower extract, and Mirabilis jalapa extract is (2-10):(0.5-2):(1-5):(2-6), the composition has a better soothing and repairing effect. Furthermore, when the mass ratio of Stephania tetrandra extract, Date palm fruit extract, Sophora flavescens flower extract, and Mirabilis jalapa extract is 5:1:3:3.5, the composition has the best effect.

[0040] Application example: A serum with soothing and repairing effects The soothing and repairing compositions prepared in Examples 1-3 were added to the serums to obtain the serums used in Examples 1-3.

[0041] The soothing and repairing essence comprises the following components by weight percentage: 4% of the soothing and repairing composition, 0.1% carbomer, 0.15% xanthan gum, 3% trehalose, 5% glycerin, 2.5% lecithin, 0.7% potassium sorbate, 0.2% arginine, and the balance being deionized water.

[0042] The preparation method of the serum with soothing and repairing effects specifically includes the following steps: S1. Mix trehalose, glycerol, carbomer, xanthan gum and some deionized water, homogenize at 70°C, add lecithin at 85°C, and stir until homogeneous to obtain mixture I. S2. When the temperature of mixture I prepared in S1 drops to 60°C, potassium sorbate is added and stirred evenly. When the system temperature drops to 35°C, each component in the composition and the remaining deionized water are added and homogenized. Finally, arginine is added to adjust the pH to obtain the essence.

[0043] Blank application example: Compared with application examples 1-3, the difference is that the essence of the blank application example does not contain the soothing and repairing composition, and uses an equal amount of deionized water instead of the soothing and repairing composition. The preparation method is the same as that of application examples 1-3.

[0044] Example 3 of efficacy test: Human skin patch test This efficacy test case evaluates the safety of the serums prepared corresponding to test cases 1-3 and the blank application case, testing the potential for the test samples to cause adverse reactions on human skin. The test follows the relevant requirements and test methods for "Human Skin Patch Test" as shown in the "Cosmetic Safety Technical Specifications" (2015 edition). Test samples: serums prepared in Application Examples 1-3 and blank application examples; The specific experimental steps are as follows: Forty volunteers, half male and half female, aged 20-35 years, without inflammatory skin diseases or highly sensitive constitutions, were selected and randomly divided into four groups of 10 each. The skin of the flexor surface of the forearm, the test site, was cleaned and kept dry. 0.025 mL of the test sample was weighed and placed in the small chamber of the plaque applicator. The control well was a blank control (without any substance). The plaque applicator containing the test sample was applied to the flexor surface of the volunteer's forearm with hypoallergenic adhesive tape, and the palm was gently pressed to ensure even application to the skin for 24 hours. Skin reactions were observed at 30 minutes (after the pressure marks disappeared), 6 hours, 12 hours, 24 hours, and 48 hours after the plaque applicator was removed, and the results were recorded according to the standards in Table 4.

[0045] Table 4. Grading Criteria for Skin Reaction in Occlusive Patch Tests

[0046] Human skin patch test results showed that all volunteers had negative results and no adverse skin reactions, indicating that the essence prepared using the composition of the present invention will not cause allergic reactions, is non-irritating, and has high safety.

[0047] Example 4 of efficacy test: Human efficacy trial This test case evaluates the soothing and repairing effects of the serum in application cases 1-3 and the blank application case.

[0048] The specific experimental steps are as follows: Twenty-four volunteers with sensitive skin and skin barrier damage (TEWL ≥ 20 g / hm2) were recruited. On the day of their visit, no products were applied to the test area (face). After washing their faces, the volunteers sat quietly for 20 minutes in an air-conditioned room with a temperature of 21±1℃ and a humidity of 50±10%. They were then randomly divided into four groups of six. The TewaMeter transdermal moisture loss probe was used to test the transdermal moisture loss. ® Hex (Courage+Khazaka) and the Colorimeter CL400 color probe measured the initial TEWL and initial a* values ​​of each volunteer's left and right sides of the face, and the average value was taken. Each group of volunteers applied 0.5 mL of serum to their face twice a day, morning and evening. On day 28, the post-treatment TEWL and post-treatment a* values ​​of the facial skin were measured again, and the average value was taken. The improvement rate (%) was calculated using the following formula:

[0049] In the formula: The initial TEWL value is the TEWL value before using the serum; The TEWL value after use was the TEWL value on day 28 of using the serum;

[0050] In the formula: The initial a* value is the a* value before using the serum; The a* value after use is the a* value on the 28th day after using the serum; Among them, the higher the TEWL value improvement rate, the stronger the skin barrier damage repair ability of the serum; the higher the a* value improvement rate, the stronger the soothing and redness-reducing ability of the serum. The specific results are shown in Table 5. Compared with the blank application example, the improvement rates of TEWL value and a* value of application examples 1-3 were significantly improved, indicating that the essence prepared by the composition provided by the technical solution of the present invention can significantly improve the soothing and repairing effect, and can significantly improve the skin's barrier function and moisture retention ability, and has the ability to soothe and reduce redness.
