Comparative Examples 3-5, in which the components of the compositions were replaced, exhibited significantly decreased moisturizing efficacy. The moisturizing and soothing compositions of the present invention exhibited significantly better moisturizing effects than the positive control. In summary, the moisturizing and soothing compositions of the present invention exhibit significant synergistic effects and can provide moisturizers for greener application formulations.

[0105] 2. In vitro test - inhibition of hyaluronidase activity test

[0106] Test principle:

[0107] Hyaluronidase (HAase) can indiscriminately hydrolyze sodium hyaluronate to produce β-N-acetylglucosamine. Under alkaline conditions, β-N-acetylglucosamine condenses with borate to form a chromogen. The chromogen reacts with p-dimethylaminobenzaldehyde (p-DMAB) in acidic conditions to produce color. This assay inhibits hyaluronidase activity by adding the analyte, limiting the enzymatic reaction. Given the conjugation effect of the generated system, the absorbance wavelength at maximum absorbance is selected as the optimal wavelength. Changes in absorbance are then examined to reflect the inhibitory efficiency of the analyte on hyaluronidase.

[0108] Experimental process

[0109] (1) Reagent setup

[0110] Acetate buffer (pH 3.5), 0.5% sodium hyaluronate, 100 U / ml hyaluronidase, 0.1% sodium hydroxide, 0.1% sodium borate, 1% dipotassium glycyrrhizate, 0.1 mol / L p-dimethylaminobenzaldehyde, Test Examples 1-5 and Comparative Examples 1-5 were diluted with acetate buffer to a sample concentration of 1%.

[0111] (2) Sample A: Add 0.5 ml of hyaluronidase, 0.5 ml of sample, 0.5 ml of sodium hyaluronate, 0.1 ml of sodium hydroxide, and 0.5 ml of sodium borate to a test tube and shake thoroughly. Then, add 1 ml of 0.1 mol / L p-dimethylaminobenzaldehyde. Incubate in a 37°C water bath for 30 min, transfer to a 96-well plate, and measure the absorbance at 582 nm.

[0112] (3) Blank control sample A: Add 0.5 ml of acetate buffer, 0.5% sodium hyaluronate, 100 U / ml hyaluronidase, 0.1% sodium hydroxide, and 0.1% sodium borate to a test tube and shake thoroughly. Then, add 1 ml of 0.1 mol / L p-dimethylaminobenzaldehyde. Incubate in a 37°C water bath for 30 min. Transfer to a 96-well plate and measure the absorbance at 582 nm.

[0113] (4) B Negative control sample: Add 0.5 ml dipotassium glycyrrhizate, 0.5 ml hyaluronidase, 0.5 ml sample, 0.5 ml sodium hyaluronate, 0.1 ml sodium hydroxide, and 0.5 ml sodium borate to a test tube and shake thoroughly. Then, add 1 ml of 0.1 mol / L p-dimethylaminobenzaldehyde. Incubate in a 37°C water bath for 30 min. Transfer to a 96-well plate and measure the absorbance at 582 nm.

[0114] (5) B Negative blank control sample: Add 0.5 ml of acetate buffer, 0.5% sodium hyaluronate, 100 U / ml hyaluronidase, 0.1% sodium hydroxide, and 0.1% sodium borate to a test tube and shake thoroughly. Then, add 1 ml of 0.1 mol / L p-dimethylaminobenzaldehyde. Incubate in a 37°C water bath for 30 min. Transfer to a 96-well plate and measure the absorbance at 582 nm.

[0115] The calculation formula of hyaluronidase activity inhibition rate (2) is:

[0116] The calculation formula of hyaluronidase activity inhibition rate (2) is:

[0117]

[0118] The test data results are shown in Table 3 Hyaluronidase activity inhibition rate

[0119] Table 3 Hyaluronidase activity inhibition rate

[0120] Sample name concentration(%) Inhibition rate (%) Example 1 1.0 54.85 Example 2 1.0 57.35 Example 3 1.0 59.95 Example 4 1.0 52.55 Example 5 1.0 54.50 Comparative Example 1 1.0 42.45 Comparative Example 2 1.0 40.05 Comparative Example 3 1.0 26.15 Comparative Example 4 1.0 24.80 Comparative Example 5 1.0 22.15 Negative control sample 1.0 23.50 Blank 1.0 0.15

[0121] in conclusion:

[0122] According to the results in Table 3, Examples 1-5 have an inhibition rate of approximately 52.55% or more on hyaluronidase, while the moisturizing and soothing compositions obtained by extracting the same compositions of Comparative Examples 1 and 2 using different solvents have an inhibition rate of approximately 40.05-42.45% on hyaluronidase, which is significantly lower in efficacy, indicating that the solvent mixing process is an ideal process. Compared with Examples 1-5, the negative control samples have significantly weaker efficacy, with the hyaluronidase inhibition rate of Examples 1-5 being more than twice that of the negative control samples. Analysis of the experimental data shows that a higher inhibition rate indicates better soothing, anti-allergic, and anti-inflammatory effects. As shown in Table 3, the moisturizing and soothing compositions of the present invention have a significant ability to inhibit hyaluronidase, indicating that they have good soothing, anti-allergic, and anti-inflammatory activities, and can relieve skin inflammatory damage to a certain extent when applied to the skin.

[0123] 3. Human body test - relief test

[0124] Fifty volunteers undergoing a skin moisture content test were tested for skin sensitivity and irritation. A 0.01% solution of 2-(4-imidazole)ethylamine dihydrochloride was sprayed onto the arms until diluted for 30 minutes. Examples 1-5 and Comparative Examples 1-5 were diluted to 1% and sprayed onto the area where 2-(4-imidazole)ethylamine dihydrochloride was applied. After 30 minutes of observation, user feedback from the volunteers was collected and averaged to analyze and evaluate the soothing and irritation-improving effects of the moisturizing and soothing composition. The results are shown in Table 4. A higher score indicates a better soothing and improvement effect on the corresponding dimension of sensitive skin.

[0125] Table 4 Soothing and improving effects on sensitive skin in five dimensions (n=50)

[0126]

[0127] in conclusion:

[0128] The results of the human body irritation test of 2-(4-imidazole)ethylamine dihydrochloride show that Examples 1-5 can soothe and improve the sensitive state of the skin in five dimensions: relieving itching, reducing swelling, tingling, removing redness, and tightness, and the soothing and repairing effects in the five dimensions are better than those of Comparative Examples 1-5.
