[0002] Inflammation is a defense response of the body to stimuli, manifested as redness, swelling, heat, pain and dysfunction. Inflammation is the body's self-defense mechanism, but at the same time it can also cause a series of skin problems. Persistent inflammation can induce sensitive skin, damage the skin barrier, and repeatedly activate the nerve response; while sensitive skin is more vulnerable to irritation and damage, and the two produce a vicious cycle, ultimately leading to more sensitive skin. Therefore, the formation of sensitive skin is closely related to inflammation. Inflammation is one of the main factors of skin sensitivity, and skin sensitivity can promote the generation and development of inflammation.

[0066] Inflammation is mainly a complex reaction caused by the interaction of various immune cells in the skin under a series of complex mechanisms. The skin cells participating in the immune inflammatory reaction regulate each other through cytokines and transmit "communication" information, ultimately leading to skin inflammation. Therefore, cosmetics for inflammatory sensitive skin have also become an important research direction.

[0067] At present, cosmetics with plant concepts are widely favored by consumers on the market, especially dendrobium, which is widely used in cosmetics. However, most cosmetics using dendrobium have many problems: First, dendrobium is used in cosmetics, mainly using its core ingredient, dendrobium polysaccharide, but the molecular weight of dendrobium polysaccharide is relatively large, and it is difficult for the skin to absorb it, and it is difficult to play its repair effect; in order to promote the skin's absorption of dendrobium, it is usually necessary to use it with a penetration enhancer, which makes it unsuitable for sensitive skin. Secondly, the sesquiterpenoid compounds contained in dendrobium have antibacterial ability, but the antibacterial ability of a single dendrobium species component is effective, and the use of preservatives cannot be greatly reduced, and its antibacterial ability to replace part of the preservatives cannot be effectively exerted. Thirdly, in the process of extraction of plant extracts, organic solvents such as methanol and ether are often selected; how to avoid the use of irritating and sensitizing solvents to ensure that the extracts do not cause new irritation and damage to the skin while exerting their efficacy is a difficulty in technical development.

[0068] Based on the above problems, the present application adopts a composite dendrobium extract containing three kinds of dendrobium extracts, which is used together with Sophora flavescens root extract and Bletilla striata root extract to obtain a repairing composition, which can play a synergistic antibacterial and soothing role. At the same time, the number average molecular weight and average viscosity of the composite dendrobium extract are regulated to promote the skin's absorption of the dendrobium extract and enhance its repair ability, so that it is suitable for people with sensitive skin.

[0069] One or more embodiments of the present application provide a repairing composition, comprising a composite dendrobium extract, a sophora flavescens root extract and a bletilla striata root extract; the number average molecular weight of the composite dendrobium extract is 6000Da-8000Da, and the average viscosity at 25°C is 100mpa·s-200mpa·s; the extraction sources of the composite dendrobium extract include Dendrobium officinale, Dendrobium nobile and Dendrobium tassellensis.

[0070] As a non-limiting example, the number average molecular weight of the composite dendrobium extract can be, but is not limited to, 6000Da, 6200Da, 6400Da, 6600Da, 6800Da, 7000Da, 7200Da, 7400Da, 7600Da, 7800Da, 8000Da or a range between any two of the above molecular weights, etc. When the number average molecular weight of the composite dendrobium extract is within the above range, it is beneficial for the composite dendrobium extract to be better absorbed and exert its repairing effect, and at the same time, it can maintain a better and more lasting moisturizing effect on the skin.

[0071] The average viscosity of the compound dendrobium extract can be, but is not limited to, 100 mPa·s, 105 mPa·s, 110 mPa·s, 115 mPa·s, 120 mPa·s, 125 mPa·s, 130 mPa·s, 135 mPa·s, 140 mPa·s, 145 mPa·s, 150 mPa·s, 155 mPa·s, 160 mPa·s, 165 mPa·s, 170 mPa·s, 175 mPa·s, 180 mPa·s, 185 mPa·s, 190 mPa·s, 195 mPa·s, 200 mPa·s, or the range between any two of the above viscosities, etc. When the average viscosity of the compound dendrobium extract is within the above range, it has a better skin feel, is not sticky, can be better absorbed by the skin and has a moisturizing effect.

[0072] It should be noted that when the mass concentration of the compound dendrobium extract is 25 mg / mL, its average viscosity is tested to be 100 mPa·s - 200 mPa·s.

[0073] The dendrobium extract mainly contains components such as polysaccharides, alkaloids, flavonoids and phenols, and sesquiterpenoids. Dendrobium polysaccharides can stimulate the function of macrophages, increase immunity and regulate biological responses, and have a good repair effect on the skin; alkaloids, flavonoids and phenols have antibacterial and anti-inflammatory effects; sesquiterpenoid compounds can effectively enhance the immune activity of the body and inhibit the growth of microorganisms such as Staphylococcus aureus, Escherichia coli, and Candida albicans. The extract of Dendrobium officinale has strong repair ability, and visa skin detection shows that the A value in the red area is significantly reduced; it shows that this dendrobium essence not only has a repair effect, but also has an anti-inflammatory and redness-reducing effect.

[0074] The Root extract of Sophora flavescens contains various alkaloids with medicinal effects. The main components are sophocarpine, D-matrine, D-oxymatrine, and also contain a small amount of D-sophoranole and L-anagyrine. The Root extract of Sophora flavescens has extremely strong anti-inflammatory and anti-allergic effects, can reduce the release of allergic mediators, is an excellent immunosuppressant, and has a good relieving effect on skin itching symptoms. The Root extract of Sophora flavescens has antibacterial effects, and has significant inhibitory effects on Gram-positive bacilli, such as Bacillus dysenteriae, Staphylococcus aureus, Salmonella albicans, and Bacillus subtilis; for Gram-negative bacteria, especially Pseudomonas aeruginosa, it has a good inhibitory effect. The Root extract of Sophora flavescens has an inhibitory effect on fungi, for example, it has different degrees of inhibitory effects on more than a dozen skin fungi such as Trichophyton rubrum.

[0075] The Bletilla striata root extract contains bibenzyl compounds and phenanthrene components. The Bletilla striata root extract has an obvious inhibitory effect on the activities of Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa and Bacillus subtilis, and has a better effect on Gram-negative bacteria than on Gram-positive bacteria, and the antibacterial effect increases with the increase of concentration.

[0076] Understandably, in the repair composition provided by the present application, a composite dendrobium extract containing three dendrobium extracts is used in combination with Sophora flavescens root extract and Bletilla striata root extract. The combined antibacterial effect is better than the single antibacterial effect, and the inhibition rate of hyaluronidase is significantly improved. Therefore, the combined use of the composite dendrobium extract with Sophora flavescens root extract and Bletilla striata root extract can play a synergistic antibacterial and soothing role. At the same time, the composite dendrobium extract has a small number-average molecular weight and low viscosity, which is beneficial to the absorption of the dendrobium extract by the skin, improves its repair ability, and makes it more suitable for use by people with sensitive skin. In addition, by combining the composite dendrobium extract with Sophora flavescens root extract and Bletilla striata root extract, the addition of traditional and non-traditional preservatives can be greatly reduced, making the product using this repair composition milder and more suitable for use by people with sensitive skin.

[0077] As a non-limiting example, the extraction sources of the composite dendrobium extract include the stems and their medicinal parts of Dendrobium officinale, the stems and their medicinal parts of Dendrobium nobile, and the stems and their medicinal parts of Dendrobium fimbriatum.

[0078] In some embodiments, the mass ratio of the compound Dendrobium extract, Sophora flavescens root extract, and Bletilla striata root extract is (1 - 5):(1 - 5):(1 - 5). As a non-limiting example, the mass ratio of the compound Dendrobium extract, Sophora flavescens root extract, and Bletilla striata root extract can be, but is not limited to, (1 - 5):(1 - 5):(1 - 5), (1 - 4.5):(1 - 4.5):(1 - 4.5), (1 - 4):(1 - 4):(1 - 4), (1 - 3.5):(1 - 3.5):(1 - 3.5), (1 - 3):(1 - 3):(1 - 3), (1 - 2.5):(1 - 2.5):(1 - 2.5), (1 - 2):(1 - 2):(1 - 2), (1 - 1.5):(1 - 1.5):(1 - 1.5), (1.5 - 5):(1.5 - 5):(1.5 - 5), (2 - 5):(2 - 5):(2 - 5), (2.5 - 5):(2.5 - 5):(2.5 - 5), (3 - 5):(3 - 5):(3 - 5), (3.5 - 5):(3.5 - 5):(3.5 - 5), (4 - 5):(4 - 5):(4 - 5), or (4.5 - 5):(4.5 - 5):(4.5 - 5), etc. When the mass ratio of the compound Dendrobium extract, Sophora flavescens root extract, and Bletilla striata root extract is within the above range, the antibacterial effect is better than that of single antibacterial agents, and the inhibition rate of hyaluronidase is significantly increased, which can play a synergistic antibacterial and soothing role; at the same time, since the three are used in combination, they have a significant antibacterial effect, and can effectively reduce the addition of traditional and non-traditional preservatives.

[0079] In some embodiments, the mass ratio of Dendrobium officinale, Dendrobium nobile, and Dendrobium fimbriatum in the extraction source of the compound Dendrobium extract is (1 - 2):(1 - 2):(1 - 2); for example, it can be, but is not limited to, (1.2 - 2):(1.2 - 2):(1.2 - 2), (1.4 - 2):(1.4 - 2):(1.4 - 2), (1.6 - 2):(1.6 - 2):(1.6 - 2), (1.8 - 2):(1.8 - 2):(1.8 - 2), (1 - 1.8):(1 - 1.8):(1 - 1.8), (1 - 1.6):(1 - 1.6):(1 - 1.6), (1 - 1.4):(1 - 1.4):(1 - 1.4), or (1 - 1.2):(1 - 1.2):(1 - 1.2), etc. When the mass ratio of Dendrobium officinale, Dendrobium nobile, and Dendrobium fimbriatum is within the above range, after being compounded with Sophora flavescens root extract and Bletilla striata root extract, the inhibition rate of the composition on hyaluronidase can reach more than 90%, and it has a good soothing effect; in addition, the diameters of the antibacterial zones of the composition against Escherichia coli (mm) and Staphylococcus aureus (mm) are both ≥20 mm, and it has a good antibacterial effect.

[0080] As a possible implementation, the extraction sources of the compound Dendrobium extract also include one or more of Dendrobium huoshanense, Dendrobium moniliforme, Dendrobium phalaenopsis, Dendrobium chrysanthum, and Dendrobium loddigesii.

[0081] One or more embodiments of the present application provide a repair product, including a repair composition and a collagen component. The repair composition includes a compound Dendrobium extract, Sophora flavescens root extract, and Bletilla striata root extract; the number-average molecular weight of the compound Dendrobium extract is 6000 Da - 8000 Da, and the average viscosity at 25°C is 100 mPa·s - 200 mPa·s; the extraction sources of the compound Dendrobium extract include Dendrobium officinale, Dendrobium nobile, and Dendrobium fimbriatum.

[0082] In the repair product, a compound Dendrobium extract containing three Dendrobium extracts is used in combination with Sophora flavescens root extract and Bletilla striata root extract, and at the same time, a collagen component is compounded to enhance the repair effect.

[0193] 1. The number-average molecular weight of the compound dendrobium extract in Examples 1-7 and Comparative Examples 5-7 was measured by the GPC method (gel permeation chromatography).

[0194] The Waters 515 gel chromatograph was used, equipped with an Ultrahydrogel chromatographic column, to calculate the number-average molecular weight and distribution of the compound dendrobium extract. The experimental conditions are as follows:

[0195] RI flow cell temperature: 40 °C; mobile phase: 50 mM acetic acid + 100 mM sodium nitrate buffer; flow rate: 0.42 mL / min; chromatographic column: Waters Ultrahydrogel 2000 column, 7.8 X 300 mm; column temperature: 40 °C; sample diluent: 50 mM acetic acid + 100 mM sodium nitrate buffer; injection volume: 50 μL; data processing software: Empower QS + GPC calculation module chromatographic data software; sample preparation: Dilute the compound dendrobium solution from 25 mg / mL to 1 mg / mL. The experimental results are shown in Table 1 and Figure 1 as follows.

[0196] Table 1

[0197]

[0198] It can be seen from the result comparison of Examples 1-5 in Table 1 that by regulating the heating time and extraction times of single water extraction within an appropriate range, it is beneficial to reduce the number average molecular weight of the compound dendrobium extract, making the number average molecular weight of the compound dendrobium extract between 6 KDa and 8 KDa.

[0199] It can be seen from the result comparison of Example 1, Examples 6-7 and Comparative Examples 5-7 that after fermentation, the number average molecular weight of the compound dendrobium extract is greatly reduced; and by controlling the mass ratio of the initial extract of compound dendrobium to Lactobacillus plantarum during fermentation within the range of (200 - 600):1, it is beneficial to regulate the number average molecular weight of the compound dendrobium extract between 6 KDa and 8 KDa; in addition, as the addition amount of Lactobacillus plantarum decreases, the reduction of the number average molecular weight of the compound dendrobium extract is relatively slow.

[0200] 2. The average viscosity of the compound dendrobium extracts in Examples 1-7 and Comparative Examples 5-7 was measured by the viscosity method.

[0201] Testing instrument: AMETEK BROOKFIELD / Brookfield DV2T viscometer; rotor speed RV1 #20 r / min; test solution: 25 mg / mL compound dendrobium extract solution; test temperature: 25 °C. The test results are shown in Table 2 and Figure 2 as follows.

[0202] Table 2

[0203]

[0204] It can be seen from the result comparison of Examples 1-5 in Table 2 that by regulating the heating time and extraction times of single water extraction within an appropriate range, it is beneficial to reduce the average viscosity of the compound dendrobium extract, making the average viscosity of the compound dendrobium extract between 100 mPa·s and 200 mPa·s.

[0205] From the result comparison of Example 1, Examples 6-7 and Comparative Examples 5-7, it can be seen that after fermentation, the average viscosity of the compound dendrobium extract is greatly reduced; and by controlling the mass ratio of the initial dendrobium extract to Lactobacillus plantarum during fermentation within the range of (200-600):1, it is beneficial to regulate the average viscosity of the compound dendrobium extract between 100 mPa·s and 200 mPa·s; in addition, as the addition amount of Lactobacillus plantarum decreases, the decrease in the average viscosity of the compound dendrobium extract is relatively slow.

[0206] 3. Inhibition zone test

[0207] The antibacterial activities of the repair essence prepared in Example 1, Examples 8-13 and Comparative Examples 1-3 against Escherichia coli and Staphylococcus aureus were investigated by the inhibition zone method to evaluate their antibacterial efficacy. Among them, the essence without compound dendrobium extract, sophora flavescens root extract and bletilla striata root extract was used as the blank control compared with Example 1. The investigation results are shown in Table 3 and Figure 3 as follows.

[0208] Table 3

[0209]

[0210] From the result comparison of Example 1, Examples 8-13 and Comparative Example 3 in Table 3, it can be seen that the essence containing compound dendrobium extract, sophora flavescens root extract and bletilla striata root extract at the same time has a significantly better inhibition zone diameter than the essence only using compound dendrobium extract, and as the addition amount of the extract increases, the inhibition zone diameter increases significantly.

[0211] From the results of Comparative Examples 1-3, it can be seen that sophora flavescens root extract has a significant inhibitory effect on Escherichia coli, bletilla striata root extract has a significant inhibitory effect on Staphylococcus aureus, and compound dendrobium extract has a significant inhibitory effect on both Escherichia coli and Staphylococcus aureus. From the result comparison of Example 1 and Comparative Examples 1-3, it can be seen that compound dendrobium extract, sophora flavescens root extract and bletilla striata root extract have a synergistic antibacterial effect.

[0212] 4. Hyaluronidase inhibition test

[0213] Hyaluronidase is the main component of the extracellular matrix of connective tissue cells in the body. Excessive hyaluronidase will promote allergic reactions and is related to most type I allergic reactions mediated by IgE and type IV allergic reactions mediated by T cells. The increase of IgE will promote the release of inflammatory factors and cause allergic phenomena.

[0214] According to GDCTC / OT-L014 "Cosmetics - Operating Procedures for Hyaluronidase Inhibition Test", the hyaluronidase inhibition test was carried out on the repair essence obtained in Example 1, Examples 8 - 13 and Comparative Examples 1 - 4. Among them, compared with Example 1, the essence without compound dendrobium extract, sophora flavescens root extract and bletilla striata root extract and the essence with collagen components were used as blank controls. The inspection results are shown in Table 4 and Figure 4 0000443as follows. 0000444

[0215] 0000445Table 4 0000446

[0216] 0000447 0000448 0000449

[0217] 0000450It can be seen from the result comparison of Example 1, Examples 8 - 13 and Comparative Example 3 in Table 4 that the essence containing compound dendrobium extract, sophora flavescens root extract and bletilla striata root extract at the same time has significantly better hyaluronidase inhibition effect than the essence only using compound dendrobium extract, and with the increase of the addition amount of the extract, the hyaluronidase inhibition rate increases significantly. 0000451

[0218] 0000452It can be seen from the result comparison of Example 1 and Comparative Examples 1 - 3 that compound dendrobium extract, sophora flavescens root extract and bletilla striata root extract have a synergistic hyaluronidase inhibition effect, that is, a synergistic soothing effect. 0000453

[0219] 0000454It can be seen from the result comparison of Example 1 and Comparative Example 4 that adding collagen components (water / soluble collagen cross-linked polymer / galactomyces ferment filtrate) is beneficial to inhibiting hyaluronidase, indicating that adding collagen components helps to enhance the soothing effect. 0000455
