Description

Technical Field

[0001] The present invention belongs to the technical field of cosmetics, and in particular relates to a soothing and repairing composition for intelligently relieving post-shave irritation and its application. Background Art

[0002] Shaving is one of the most common grooming behaviors among men, and it can cause some skin irritation, typically manifesting as temporary redness accompanied by burning and itching. This may involve mechanical neuroinflammation, in which sensory nerve fibers are activated, leading to the release of neuropeptides, which in turn triggers an inflammatory response. Furthermore, the friction and cutting action of the blade against the skin during shaving can damage part of the stratum corneum on the surface of the skin, weakening the skin's barrier function. Furthermore, hair follicles are stimulated to a certain extent, which prompts the sebaceous glands to secrete more sebum to moisturize and protect the skin.

[0003] In addition, men's facial skin is heterogeneous in morphology and roughness, the physiological characteristics of the skin in different areas vary significantly, and there are also certain differences in hair distribution in different parts. For example, the skin on the cheeks is relatively smooth, and the risk of skin irritation during shaving is lower. However, the skin on the neck is rougher than the skin on the cheeks, and the risk of skin irritation after shaving in this area is higher. Due to the higher density of beard in the upper lip area, the force during shaving and the number of shavings per area may be increased, thereby increasing the risk of skin irritation caused by shaving. In addition, the thickness and elasticity of the skin in different facial areas are also different, which may affect the contact and cutting efficiency of the blade with the skin during shaving. The different sensitivities of the skin in different facial areas to mechanical and thermal stimulation may also lead to differences in skin reactions after shaving.

[0004] Most aftershave products on the market focus on soothing and moisturizing effects, and no products have been developed specifically for the different levels of post-shaving damage in different areas. In areas with less severe or no damage, the release of higher levels of active ingredients may cause skin irritation, while in more severely damaged areas, lower levels of active ingredients may not provide the desired soothing and moisturizing effects. Therefore, aftershave products need to tailor their treatments to the varying degrees of damage inflicted on different areas of facial skin, thereby enhancing the product's soothing and repairing effects. Summary of the Invention

[0005] In response to the above-mentioned defects or improvement needs of the prior art, the present invention provides a soothing and repairing composition that intelligently relieves aftershave irritation, as well as an aftershave product prepared using the soothing and repairing composition, to solve the problem that existing aftershave products lack soothing and repairing products for different damage conditions.

[0081] Test Example 1 Hyaluronidase Inhibition Experiment

[0082] Test sample: Deionized water was added to the compositions 1-10 prepared in Example 1 of the present invention, and the mixture was mixed to obtain a test sample with a concentration of 0.5%;

[0083] Hyaluronic acid, also known as hyaluronic acid, is a powerful moisturizer that attracts and locks in moisture, maintaining skin hydration and improving dry, rough, and dehydrated skin conditions. Furthermore, hyaluronic acid can enhance the biological activity of cells, providing a strong synergistic effect on repairing and protecting the skin. Therefore, by inhibiting hyaluronidase, the decomposition rate of hyaluronic acid in the skin is reduced, thereby achieving long-term hydration, moisturizing, and repairing the skin, which is of great significance.

[0084] (1) Take four groups of clean test tubes, label them A, B, C, and D, add 50 μL of the sample to be tested to test tubes A and B, add 50 μL of distilled water to test tubes C and D, add 50 μL of 500 U / mL hyaluronidase solution to test tubes A and C, and add 50 μL of pH 5.6 acetate buffer to test tubes B and D. Place the test tubes in a 37°C incubator for 20 min.

[0085] (2) Add 10 μL of 2.5 mol / L CaCl2 solution to each of the four test tubes and then place them in a 37°C incubator for 20 min.

[0086] (3) Add 50 μL of 0.5 mg / mL sodium hyaluronate solution to test tubes A and C, and add 50 μL of pH 5.6 acetate buffer to test tubes B and D. Place the test tubes in a 37°C incubator for 40 min, then take them out and let them stand at room temperature for 10 min.

[0087] (4) 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. Place the test tubes in a boiling water bath for 30 min, then in an ice bath for 10 min, and finally at room temperature for 10 min.

[0088] (5) Add 100 μL of P-DAB reagent to each test tube and measure the absorbance at 530 nm using a microplate reader;

[0089] The hyaluronidase inhibition rate was calculated as follows:

[0090]

[0091] Where: A is the OD value of the sample solution; B is the OD value of the sample blank; C is the OD value of the control sample solution; D is the OD value of the control sample blank;

[0092] The calculated data are shown in Table 1 below;

[0093] Table 1 Hyaluronidase inhibition rate

[0094]

[0095]

[0096] Compositions 1-3 are prepared according to the components and preparation method of the present application. Compared with composition 1, compositions 4-6 do not add Norway spruce leaf extract, myrtle fruit extract, Bordeaux leaf extract, and serrata extract, respectively. Compositions 7-8 have different ratios of Norway spruce leaf extract, Bordeaux leaf extract, myrtle fruit extract, and serrata extract. Compositions 9-10 have different types of extracts, using white osmanthus leaf extract and long-hearted Kappaphycus extract instead of Bordeaux leaf extract and serrata extract, respectively.

[0097] As can be seen from Table 1, combined with the data of composition 1 and compositions 4-6, when Norway spruce leaf extract, Bordeaux leaf extract, myrtle fruit extract and serrata vesiculosus extract are used in combination, the soothing, moisturizing and repairing performance is better. When Norway spruce leaf extract and myrtle fruit extract, Bordeaux leaf extract and serrata vesiculosus extract are missing respectively, the soothing, moisturizing and repairing performance of the composition decreases.

[0098] Combining the data of compositions 1-3 and 7-8, it can be seen that when the weight ratio of Norway spruce leaf extract, Bordeaux leaf extract, myrtle fruit extract and Fucus serrata extract is (1-5): (0.1-1): (0.1-1): (0.1-2), the soothing, moisturizing and repairing properties of the composition reach a better level.

[0099] Combining the data of composition 1 and compositions 9-10, it can be seen that when Bordeaux leaf extract, Fucus vesiculosus extract, Norway spruce leaf extract and myrtle fruit extract are compounded, the composition's ability to inhibit hyaluronidase is improved, and the combination of the four has relatively better soothing, moisturizing and repairing properties.

[0100] Test Example 2 Effect of releasing active ingredients of the composition at different pH

[0101] Test substances: compositions 1-3 prepared in the examples of the present invention;

[0102] The release capacity of the composition under different pH conditions was investigated using the flavonoid components in the composition as an indicator: the flavonoid content in the test substance was first determined by ultraviolet spectrophotometry. 1 g of the test substance was then soaked in 20 mL of acetate buffer (pH 6.5) or PBS buffer (pH 7.4) for 4 hours, centrifuged at 4000 rpm for 10 minutes, and the supernatant was collected and the flavonoid content in the supernatant was determined by ultraviolet spectrophotometry.

[0103] Flavonoid content was determined using ultraviolet spectrophotometry, referring to the method in the 2010 edition of the Chinese Pharmacopoeia. The specific experimental procedure was as follows: the test substance was diluted with water to a 2% test solution. 1.0 mL of the test solution and 1.0 mL of distilled water were placed in 15 mL stoppered colorimetric tubes. 0.5 mL of 5% sodium nitrite was added to each colorimetric tube, mixed, and incubated at room temperature for 6 minutes. 0.5 mL of 10% aluminum nitrate was added to each colorimetric tube, mixed, and incubated at room temperature for 6 minutes. 5 mL of 4% sodium hydroxide was added to each colorimetric tube, mixed, and incubated at room temperature for 15 minutes. The absorbance was measured at 510 nm. A calibration curve was constructed using standard rutin solutions with a mass concentration range of 0.2-1.2 mg / mL, with absorbance as the ordinate and mass concentration as the abscissa. A linear equation was obtained.

[0104] Flavonoid content = X × N × V;

[0105] Where: X is the mass concentration of flavonoids in the test solution calculated by the linear equation, mg / mL;

[0106] N is the dilution factor of the test solution;

[0107] V is the volume of the liquid to be tested;

[0108] The final results are expressed as flavonoid release rate, that is, flavonoid content in the supernatant / flavonoid content in the composition. The results are shown in Table 2:

[0109] Table 2 Data of flavonoid release rate

[0110]

[0111] The surface of normal skin is weakly acidic, but the pH value of the skin will increase to neutral or even weakly alkaline after the barrier is damaged. As shown in Table 2, the flavonoid release rates of compositions 1-3 were tested under pH = 7.4 and pH = 6.5, respectively. Compared with the flavonoid release rate under pH = 6.5, the flavonoid release rate under pH = 7.4 was significantly increased, indicating that the flavonoid release rates of compositions 1-3 prepared by the present invention were better under pH = 7.4. In addition, the four plant ingredients are encapsulated in a pH-sensitive carrier, so that the soothing and repairing composition is slowly released on normal skin and quickly released at the damaged barrier, thereby having a better soothing and repairing effect.

[0112] Application example: Preparation of aftershave products

[0113] The aftershave products 1-10 described in this application example are prepared according to the following weight percentages: 5% of the composition 1-10 prepared in Example 1 of the present invention, 5% glycerin, 3% sorbitol, 5% propylene glycol, 0.5% p-hydroxyacetophenone, 0.5% hexylene glycol, 0.05% EDTA-2Na, and the balance deionized water.

[0114] The preparation method of the aftershave product 1-10 comprises the following steps:

[0115] A1. Weigh p-hydroxyacetophenone, hexylene glycol, and propylene glycol, mix well, and dissolve at 60°C. Then cool to 45°C to obtain a mixed solution II.

[0116] A2. Add 5 times the amount of deionized water to the composition prepared by the present invention and mix well. Then add mixed solution II, stir well and divide into portions to obtain the aftershave product.

[0117] Test Example 3: Product oil control, moisturizing, soothing and repairing effect test

[0118] 60 male volunteers aged 18-45 were selected. On the day of the test, they did not apply any skin care products and did not shave. After washing their faces, the subjects sat quietly in a constant temperature and humidity room at 21±1°C and 50±10% humidity for 30 minutes.

[0119] The subjects were randomly divided into 10 groups, with 6 people in each group. The skin oil content tester Sebumeter (SM815, Courage and Khazaka) and moisture probe CM 825 (Courage+Khazaka), transepidermal water loss probe Initial facial oil content, moisture content, and TEWL values were tested using the TM Hex (Courage + Khazaka) system. Facial images were taken using a Visia-7, and the derived red zone images were analyzed to obtain initial a* values. Subjects used the aftershave product prepared according to the present invention daily after shaving, with a dosage of approximately 1 mL per application. Each indicator was tested after shaving and follow-up visits were conducted on days 7 and 14. Improvements in each subject's oil content, moisture content, TEWL value, and a* value were analyzed on days 7 and 14. Improvement was expressed as the improvement rate for each value, calculated as follows:

[0120] Improvement rate (%) = |(X 使用后 -X 使用前 ) / X 使用前 ×100%|;

[0121] Where:

[0122] X使用前 Data on various indicators tested before the subjects used the product;

[0123] X 使用后 Data on various indicators tested before the subjects used the product;

[0124] The calculated data are shown in Table 3-4 below;

[0125] Among them, shaving requires the use of an electric shaver, and the shaving frequency is once a day. No hot compresses or soaking of the corresponding parts before shaving are required. The time and force of each shaving are based on your own habits to shave the beard cleanly;

[0127]

[0128]

[0129] Table 4 Effect test results of using the product for 14 days

[0130]

[0131] Aftershave products 1-3 are products prepared according to the components and preparation method of the present application. Compared with aftershave product 1, aftershave products 4-6 do not add Norway spruce leaf extract, myrtle fruit extract, Bordeaux leaf extract, and serrata vesiculosus extract, respectively. Aftershave products 7-8 have different ratios of Norway spruce leaf extract, Bordeaux leaf extract, myrtle fruit extract, and serrata vesiculosus extract. Aftershave products 9-10 have different types of extracts, using white osmanthus leaf extract and Kappaphycus longifolia extract instead of Bordeaux leaf extract and serrata vesiculosus extract, respectively.

[0132] As shown in Tables 3-4, compared with aftershave products 4-10, the oil improvement rate, moisture improvement rate, TEWL value improvement rate and a* value improvement rate of aftershave products 1-3 were significantly increased, indicating that the combination of the four ingredients of Norway spruce leaf extract, Bordeaux leaf extract, myrtle fruit extract and Fucus serrata extract synergistically improves the oil control, moisturizing, soothing and repairing effects of the products.

[0133] From the data of seven days of use of the products in Table 3, it can be seen that compared with aftershave product 1, the oil improvement rate, moisture improvement rate, TEWL value improvement rate and a* value improvement rate of aftershave products 4-6 all decreased significantly, indicating that the four ingredients of Norway spruce leaf extract, Bordeaux leaf extract, myrtle fruit extract and serrata vesiculosus extract synergize with each other, thereby affecting the oil control, moisturizing, soothing and repair effects of the products; compared with aftershave product 1, the oil improvement rate, moisture improvement rate, TEWL value improvement rate and a* value improvement rate of aftershave products 7-10 all decreased significantly, and the oil improvement rate, moisture improvement rate, TEWL value improvement rate and a* value improvement rate of aftershave products 9-10 were lower than those of aftershave products 7-8, indicating that both the component ratio and the type of extract will affect the oil control, moisturizing, soothing and repair effects of the product, and the influence of the extract type is greater than the component ratio.

[0134] Combining the data in Tables 3 and 4 for seven and fourteen days of use respectively, it can be seen that the oil improvement rate, moisture improvement rate, TEWL value improvement rate and a* value improvement rate of aftershave products 1-10 all increased significantly, indicating that with the increase in usage time, the products have better soothing and repairing effects on the skin.

[0135] In summary, the composition of the present invention achieves synergistic effects through the four ingredients of Norway spruce leaf extract, Bordeaux leaf extract, myrtle fruit extract and Fucus vesiculosus extract, and its application in after-shave products significantly improves the oil control, moisturizing, soothing and repairing effects; the present invention uses carboxymethyl deacetylated chitosan to prepare the composition, and the prepared composition has an intelligent care effect on barrier damaged areas.
