[0039] Additional aspects and advantages of the present application will be partially given in the following description, which will become apparent from the following description, or will be understood through the practice of the present application. DETAILED DESCRIPTION

[0040] In order to more fully understand the technical content of the present application, the present application will be further introduced and illustrated in conjunction with specific embodiments below; obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments; based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making any creative work are within the scope of protection of the present application.

[0041] For those skilled in the art, the features, beneficial effects and advantages of the present application will become apparent by reading the contents disclosed in this specification.

[0042] The term "mass content" herein may be represented by the symbol "part(s)".

[0043] In the following schemes, the corresponding raw materials can be purchased from the market or prepared according to the common knowledge known in the art.

[0044] In the examples of the present application, collagen peptides were purchased from Guangdong Baiwei Biotechnology Co., Ltd., Centella asiatica extract was purchased from Shanyang Lianfeng Biotechnology Co., Ltd., yeast / rice fermentation product filtrate was purchased from Guangzhou Zhaoyi Biotechnology Co., Ltd., saponin extract was purchased from Guangzhou Baoyi Biotechnology Co., Ltd., and olive leaf extract was purchased from Guangzhou Shengkais Chemical Co., Ltd.

[0045] The antibacterial repair composition of the present application is described in detail below.

[0046] Antibacterial repair composition

[0047] The antibacterial repair composition of the present application comprises: collagen peptide, Centella asiatica extract, yeast / rice fermentation product filtrate, sapodilla extract and olive leaf extract.

[0048] The Centella asiatica extract used in this application has antibacterial and anti-inflammatory effects. At the same time, the Centella asiatica extract tightens the connection between the epidermis and the dermis, making the connection between the epidermis and the dermis more compact, and can help the formation of collagen in the dermis, regenerate fibrin and reconnect, thereby achieving a repairing effect on the skin.

[0049] However, the skin utilization rate of Centella asiatica extract is relatively low, and its effect is difficult to exert, especially on damaged skin. In the prior art, some penetration enhancers are usually used to help skin utilization, such as menthol and azone, but the above-mentioned penetration enhancers are irritating and can easily cause irritation to the skin during use.

[0050] The collagen peptide used in this application has peptide molecules that can be quickly absorbed, thereby repairing the body's skin cells, repairing the skin barrier, restoring skin elasticity, and restoring skin radiance. It can also reduce inflammatory responses and reduce the level of inflammatory mediators in the body.

[0051] The yeast / rice fermentation product filtrate used in the present application can activate body cells and prevent skin roughness; it has a small molecular weight and super strong permeability, can quickly penetrate the skin, promote epidermal cell activation and renewal, and at the same time can promote collagen production and elastic fiber renewal, thereby increasing skin elasticity.

[0052] The soapberry extract used in the present application has a good antibacterial effect on Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, Enterobacter cloacae, Salmonella enterica and Candida albicans.

[0053] The olive leaf extract used in the present application not only has excellent antibacterial effect, but also can promote fibroblasts to produce collagen, thereby increasing skin elasticity.

[0054] The present application uses collagen peptide, Centella asiatica extract, yeast / rice fermentation product filtrate and olive leaf extract as the antibacterial repair composition, which not only has excellent antibacterial effect, but also can comprehensively resist the inflammation caused by skin problems and help the skin to repair quickly. The principle may be:

[0055] On the one hand, collagen peptides and yeast / rice fermentation product filtrate both have excellent permeability, can quickly repair the body's skin cells, rebuild the skin barrier, and promote the skin's absorption of Centella asiatica extract, thereby improving the skin utilization rate of Centella asiatica extract; on the other hand, the Centella asiatica extract with significantly improved skin utilization rate can not only participate in the bactericidal effect of Gleditsia sinensis extract and olive leaf extract, thereby improving the overall bactericidal performance of the antibacterial repair composition, but can also work together with olive leaf extract, collagen peptides and yeast / rice fermentation product filtrate to further resist inflammation caused by the skin and promote the production of collagen and the renewal of elastic fibers, thereby increasing skin elasticity and achieving the effect of repairing the skin.

[0056] The antibacterial repair composition provided in the present application has the dual effects of antibacterial and skin repair.

[0107] Effect verification

[0108] The effects of the antibacterial repair liquid prepared in the above Examples 1-6 and Comparative Examples 1-5 were verified, specifically including:

[0109] Antibacterial performance test:

[0110] The spunlace nonwoven fabric was immersed in the corresponding antibacterial repair liquid at 25° C. for 15 minutes to obtain the antibacterial repair wet wipes.

[0111] The antibacterial properties of the wet wipes were determined with reference to FZ / T73023-2006 "Antibacterial Knitwear", and the test strains were: Escherichia coli, Staphylococcus aureus, and Candida albicans. The antibacterial properties were expressed as the inhibition rate. The test results are shown in Table 3 below.

[0112] Table 3: Antibacterial rate (%) of Examples 1-6 and Comparative Examples 1-5

[0113] Antibacterial rate Example 1 Example 2 Example 3 Example 4 Example 5 Example 6 Comparative Example 1 Comparative Example 2 Comparative Example 3 Comparative Example 4 Comparative Example 5 Escherichia coli 99.5 98.5 99.5 98.2 98.3 98.6 86.6 88.2 82.5 81.5 80.9 Staphylococcus aureus 98.6 98.2 99.8 97.4 97.3 97.8 86.7 88.5 82.7 81.3 80.7 Candida albicans 98.2 96.8 98.7 96.5 96.6 96.9 85.8 87.6 81.8 80.4 80.0

[0114] According to the test results in Table 3, Examples 1-5 of the present application selected collagen peptides, Centella asiatica extract, yeast / rice fermentation product filtrate and olive leaf extract as antibacterial repair compositions, which have excellent antibacterial effects.

[0115] Among them, in Comparative Example 1-2, due to the lack of collagen peptides or yeast / rice fermentation product filtrate, the skin utilization rate of Centella asiatica extract was significantly reduced, which in turn caused the antibacterial effect of Comparative Example 1-2 to be significantly weakened.

[0116] In Comparative Examples 3-5, due to the lack of Centella asiatica extract, Gleditsia sinensis extract or Olive Leaf Extract, the antibacterial effect of Comparative Examples 3-5 is also significantly weakened, indicating that Centella asiatica extract, Gleditsia sinensis extract and Olive Leaf Extract have a synergistic effect in antibacterial effect.

[0117] Skin penetration test of Centella asiatica extract

[0118] The skin permeation test of the Centella asiatica extract refers to the existing Franz diffusion cell method;

[0119] The specific experimental steps are:

[0120] The dorsal skin of healthy male Wistar rats was used as the permeability barrier in an in vitro Franz diffusion cell experiment;

[0121] Fix the intact skin between the receiving pool and the supply pool (with the inner layer of the skin facing the receiving pool) to ensure that there are no bubbles between the skin and the receiving solution;

[0122] Diffusion cell parameters: effective diffusion area is about 3.15cm 2, the volume of the receiving cell was about 8.8 mL, the magnetic stirring speed was 600 rpm, and the temperature of the receiving solution was 36.0 ± 0.1 °C;

[0123] The receiving pool was filled with the release medium 1% SDS-10% ethanol-normal saline, bubbles were removed, stirring was started, and the temperature was kept constant at (36.0±0.1)℃, and about 1g of the sample was evenly applied to the skin surface (n=8);

[0124] At 1, 2, 4, 6, 8, 10, and 12 hours, 0.5 mL of the receiving solution was drawn, and the same volume of release medium at the same temperature was added immediately after sampling. The concentration of the Centella asiatica extract in the receiving solution filtered through a 0.22 μm filter membrane was determined by HPLC. The cumulative drug permeation at different times was calculated.

[0125] The cumulative transdermal amount of Centella asiatica extract per unit area was calculated according to the following formula:

[0126] ;

[0127] In the above formula: Q: cumulative transdermal amount; S: effective diffusion area; V: volume of saline in the receiving pool; C i : drug concentration in the receiving solution from the first sampling to the last sampling; C n : drug concentration in the receiving solution during sampling; m0: theoretical sample weight; m: actual sample weight.

[0128] The test results are shown in Table 4.

[0129] Table 4: Cumulative skin penetration of Centella asiatica extract (12h)

[0130] Example 3 Comparative Example 1 Comparative Example 2 Cumulative permeation of Centella asiatica extract <![CDATA[1424μg / cm 2 ]]> <![CDATA[525μg / cm 2 ]]> <![CDATA[568μg / cm 2 ]]>

[0131] According to the test results in Table 4, in the absence of one of the collagen peptides or the yeast / rice fermentation product filtrate, the skin utilization rate of the Centella asiatica extract decreases significantly, indicating that in the scheme of the present application, the combined action of the collagen peptides and the yeast / rice fermentation product filtrate can quickly repair the body's skin cells, rebuild the skin barrier, and promote the skin's absorption of the Centella asiatica extract, thereby improving the skin utilization rate of the Centella asiatica extract and further exerting the antibacterial and repairing effect of the Centella asiatica extract.

[0132] Repair effect test

[0133] Test subjects: 110 healthy women aged 25-45, divided into 11 groups, 10 people in each group.

[0134] Test area: face (the left face is blank control, the right face uses comparative example sample or embodiment sample).

[0135] Usage: Apply once in the morning and evening (same dosage) for 28 days.

[0136] Testing instrument: CK skin tester (Germany)

[0137] Test parameters: moisture content of skin stratum corneum, transepidermal water loss

[0138] After 28 days, the CK skin tester (Germany) was used to measure the change rate of the moisture content of the stratum corneum and the change rate of the transepidermal water loss of the skin. The higher the change rate of the moisture content of the stratum corneum, the better the moisture content of the skin; the lower the change rate of the transepidermal water loss, the better the skin barrier. The test results are shown in Table 5.

[0139] Table 5:

[0140] Sample set Moisture content change rate (%) Transepidermal water loss change rate (%) Example 1 5.46 1.53 Example 2 5.55 1.45 Example 3 5.68 1.34 Example 4 5.52 1.43 Example 5 5.25 1.64 Example 6 5.26 1.66 Comparative Example 1 3.02 2.89 Comparative Example 2 3.15 2.75 Comparative Example 3 3.55 2.08 Comparative Example 4 4.46 1.87 Comparative Example 5 4.35 1.91

[0141] According to the test results in Table 5, Examples 1-6 of the present application can effectively help the skin to repair quickly by selecting collagen peptides, Centella asiatica extract, yeast / rice fermentation product filtrate and olive leaf extract as antibacterial repair compositions.

[0142] Among them, in Comparative Example 1-2, in the absence of collagen peptides or yeast / rice fermentation product filtrate, the skin utilization rate of Centella asiatica extract was significantly reduced. At the same time, since collagen peptides and yeast / rice fermentation product filtrate themselves can repair the body's skin cells and rebuild the skin barrier, the repair effect of Comparative Example 1-2 was significantly weakened.

[0143] In Comparative Example 3, due to the lack of Centella asiatica extract, its repair effect was significantly weakened, indicating that Centella asiatica extract and collagen peptides, yeast / rice fermentation product filtrate have a synergistic effect in repair.

[0144] When the comparative examples 4-5 lacked the saponin extract or the olive leaf extract, the repair effect of the comparative examples 4-5 was also weakened, indicating that the saponin extract and the olive leaf extract also had some influence on the repair effect in the scheme of the present application, but the overall influence was relatively small.

[0145] Safety Testing

[0146] 1. Number of testers: 36 in total, including 18 males and 18 females; youngest age: 25 years old, oldest age: 40 years old; the average age meets the inclusion criteria.
