Inflammatory factor inhibition test

TNF-α is the most common inflammatory factor in inflammatory reactions. It can induce the phenotype of vascular endothelial cells to change to an inflammatory type, leading to changes in the body's metabolism and hemodynamics, and promoting the production of inflammatory mediators. Inflammatory mediators can increase vascular permeability, causing local congestion and edema, and may stimulate nerve endings to cause itching and pain. Therefore, the inhibition of TNF-α helps soothe and repair the skin.

RAW264.7 cells grown to the logarithmic phase were inoculated in a 24-well plate at a density of 1.5×10 ⁵ /mL, with 800 μL of cell suspension per well, and cultured in a 37°C, 5% CO ₂ incubator for 24 hours. When the cells grew to near confluence, 50 μL of the sample concentration of 10 mg/L was administered, with 3 replicates per group, and 50 μL of 10 μg/mL dexamethasone was used as the positive control. After 1 hour, 1 μg/mL lipopolysaccharide (LPS) was used for stimulation. After 24 hours of incubation in a cell culture incubator, the cell culture medium was transferred to a centrifuge tube, centrifuged at 5000 r/min for 10 minutes, and the cell supernatant was collected and tested according to the instructions of the mouse TNF-α enzyme-linked immunosorbent assay kit.

Comparing Example 2 with Comparative Examples 1-5, Example 2 has the best effect, indicating that the composition of different components can have a certain degree of influence on the efficacy of inhibiting TNF-α inflammatory factors, indicating that there is a certain synergistic effect in the composition. Any replacement or omission of the raw materials or components defined in the present invention cannot achieve the efficacy proposed by the present invention.

Effect of the composition on moisturizing of zebrafish

The zebrafish epidermis has a certain osmotic pressure tolerance range, and water loss will occur if the tolerance range is exceeded. Using a high osmotic pressure solution to treat zebrafish will cause its tail to shrink and shrink due to water loss. Therefore, an induced model of zebrafish hydration and moisturizing can be established to evaluate the effect of moisturizing products.

(1) Breeding: Zebrafish were paired at a male-female ratio of 2:1, and the eggs were collected and incubated overnight (28°C incubator).

(2) Experimental groups: The experiment set up a blank control group and an experimental group. The experimental groups included a model group, a positive group, and a sample group, with 8 2 dpf fry in each group.

(3) Solution preparation: Accurately weigh 1 mg of sample and prepare the sample solution to be tested, use urea (0.05%) as the positive control for the experiment, and add 1 mg to each well. After the administration is completed, place the 6-well plate in a 28°C incubator in the dark for 24 hours.

Test results: as shown in Table 6 below.

From the results of Example 2 and Comparative Examples 1-5, it is shown that there is a certain synergistic effect when using the components defined in the present invention, and the effect achieved by the present invention cannot be achieved by omitting or replacing any one of them.

Effects of the composition on the migration of Hacat cells through scratch wound

The degree of cell migration has an important impact on wound healing and skin repair. In the process of wound healing, cell migration is an important step for epidermal cells to cover the wound, so the higher the cell migration rate, the faster the wound heals. At the same time, cell migration is also involved in the repair process after skin damage. If cell migration is impaired, it will lead to skin repair disorders, which in turn cause various skin diseases.

Inoculate cells into 12-well plates at the corresponding inoculation density and incubate overnight at 37°C in a _CO2 incubator. When the cell plating rate in the 12-well plate reaches about 80%, scratch the sample group and the solvent control group. After the scratching, wash the cells with PBS to remove dead cells, add fresh EGF-free keratinocyte culture solution, add 50μL of 10mg/L according to Example 1-3 and Comparative Example 1-5, and take photos and record using an inverted microscope. Incubate in a 37°C, 5% _CO2 incubator for 24h, take photos and record again, and use ImageJ software for statistical analysis.

Test on the immediate repair effect of skin care gel on human body

Transepidermal water loss (TEWL) is an important parameter for evaluating skin barrier function. It indicates the loss of water from the deep dermis through evaporation of the epidermis. The higher the TEWL, the more water is lost through the skin and the weaker the skin's moisturizing ability.

The transepidermal water loss rate is closely related to the hydration of the stratum corneum and is a commonly used indicator reflecting the barrier function of the stratum corneum. In the development of cosmetics, the efficacy of moisturizing cosmetics can be evaluated by testing the TEWL value of skin water loss. In addition, the transepidermal water loss rate can also be used in allergic patch tests, contact dermatitis, physical therapy, burns and new tissue monitoring to promptly detect whether the protective function of the skin has been damaged.

Therefore, transepidermal water loss rate is an important parameter for assessing skin health and is of great significance to the research, development and evaluation of moisturizing products.

50 healthy subjects aged 18-60 years old with no damage on the inner side of the arm were selected and divided into groups, each group had 10 people, and each group of subjects consisted of 5 males and 5 females. A sample group and a blank group (i.e., a negative control group: excluding the test sample) were set up, and the test area was randomly distributed in the ¹ cm2 area on the inner side of the volunteer's arm. The forearm (two areas) of the above-mentioned subject was torn off with medical tape 20 times to induce skin barrier function damage, and then 5 mg/mL histamine was added to model for 10 min (obvious erythema appeared), one of which used 1g of the test product, and the other area was blank as a negative control area. Before the tape was torn off (T0), before using the product (i.e., immediately after histamine) (T1), and 2 hours after using the product (T2), the transepidermal water loss rate (TEWL) of the forearm skin was collected, and the difference in skin index changes in the product treatment area and the negative control area before and after using the product was used to evaluate the short-term repair effect of the product on the skin barrier damage caused by tape tearing and histamine-induced skin irritation, and the average value was taken. The results obtained are shown in Table 8 below.
