Abstract
Description
Technical Field
[0001] This application relates to the field of cosmetic technology, and more specifically, to an anti-inflammatory and repairing composition, its preparation method, and its application. Background Technology
[0002] The skin barrier comprises physical, chemical, microbial, and immune barriers, playing a crucial role in protecting the body from harmful factors such as chemical (e.g., detergents, soaps), physical (e.g., temperature, radiation, mechanical damage), and microbial stimuli, as well as maintaining relative internal homeostasis. Damage to the skin barrier leads to skin sensitivity and fragility, causing significant moisture loss and triggering inflammation upon external stimuli. Skin inflammation occurs when skin tissue is stimulated by external factors, causing keratinocytes, the main cells of the epidermis, to release pro-inflammatory factors (e.g., IL-1α, TNFα) and chemokines (e.g., IL-8). These pro-inflammatory factors further bind to corresponding receptors on the cell membrane, activating inflammation-related signaling pathways (e.g., NF-κB), resulting in the production of more inflammatory factors. This amplifies the inflammatory cascade, inducing vascular reactions and symptoms such as erythema. In recent years, inflammatory skin diseases caused by environmental pollution, life stress, and cosmetic intolerance have been on the rise, causing significant disruption to people's lives. Therefore, the development of cosmetic ingredients and cosmetics with anti-inflammatory and repairing effects for people with inflammatory skin is receiving increasing attention and favor from the industry and consumers.
[0003] Centella asiatica is the dried whole herb of the plant Centella asiatica, belonging to the Apiaceae family. Clinically, it is widely used for anti-inflammatory, anti-ulcer, and wound-healing purposes. Centella asiatica contains active triterpenoid saponins, primarily asiaticoside, asiaticoside, and asiatic acid. Current techniques for preparing Centella asiatica extracts mostly employ solvent extraction and resin purification methods. Solvent extraction generally involves high temperatures, which accelerates the hydrolysis of asiaticoside and asiaticoside, affecting the yield. It also consumes a significant amount of energy, hindering energy conservation. Subsequent purification processes, such as resin enrichment and crystallization, are numerous, lack automation, and are difficult to scale up for industrial production. Domestically produced anti-inflammatory compositions containing asiaticoside primarily repair the skin's physical barrier, without addressing the simultaneous repair of the microbial barrier and the acidic chemical barrier.
[0004] Peony root bark extract is a natural plant extract derived from peony root bark. Its main components include various active substances with multiple biological activities such as antioxidation, antibacterial, and anti-inflammatory properties. The main effective substances in peony root bark extract include paeoniflorin, saponins, polyphenols, and flavonoids. These components possess various biological activities such as antioxidation, antibacterial, and anti-inflammatory properties, and can be used to prevent and improve oxidative stress-related diseases and inflammatory diseases. They can also be used in skincare product formulations to improve dry and aging skin. Paeonol is the main anti-inflammatory component in peony root bark extract. It is readily soluble in ethanol and slightly soluble in water. Paeonol has analgesic and anti-inflammatory effects. In daily chemical applications, paeonol can also inhibit intracellular O2. 2- The generation of free radicals can whiten the skin, reduce and fade pigment deposits in the skin, and has effects such as fading bruises and spots, reducing inflammation, swelling and pain, anti-allergy, and antiviral.
[0005] There are many causes of skin inflammation. Although asiaticoside and paeonol both have certain anti-inflammatory effects, their individual effects are relatively weak. Furthermore, when a single component acts on the skin, it cannot achieve different mechanisms of action to anti-inflammate and repair the skin. Therefore, a new method is needed to address these issues. Summary of the Invention
[0006] To overcome the above-mentioned technical defects, this application provides an anti-inflammatory repair composition and its application. The composition uses Centella asiatica extract and Paeonia suffruticosa root bark extract to achieve anti-inflammatory and skin repair through different mechanisms of action. Moreover, the combination of the two can synergistically enhance the anti-inflammatory effect and has good application prospects in cosmetics.
[0007] To achieve the above-mentioned technical objectives, this application provides an anti-inflammatory repair composition and its application, employing the following technical solution:
[0008] An anti-inflammatory and repairing composition comprising Centella asiatica extract and Paeonia suffruticosa root bark extract, wherein the mass ratio of Centella asiatica extract to Paeonia suffruticosa root bark extract is 1:(0.5-1).
[0009] Preferably, the mass ratio of the Centella asiatica extract to the peony root bark extract is 1:0.8.
[0010] By adopting the above technical solution, the main anti-inflammatory components of Centella asiatica extract and Paeonia suffruticosa root bark extract are asiaticoside and paeonol, respectively, and the combination of the two has a good synergistic anti-inflammatory effect. In addition, Centella asiatica extract and Paeonia suffruticosa root bark extract also contain other ketones, phenols, and glycosides with anti-inflammatory effects. The above composition provided in this application can promote the secretion of anti-inflammatory factors that repair the skin barrier by skin cells and inhibit the expression of inflammatory factors IL-1α and IL-6 to exert anti-inflammatory effects.
[0011] More preferably, the preparation method of the Centella asiatica extract is as follows:
[0012] A1. Degrease the Centella asiatica powder to obtain defatted Centella asiatica powder;
[0013] A2. Mix defatted Centella asiatica powder with water, add cellulase, hemicellulase and pectinase, and extract by ultrasonication to obtain a mixture;
[0014] A3. Alkaline protease was added to the mixture for enzymatic hydrolysis, the supernatant was collected by ultrafiltration, and the mixture was concentrated under vacuum and freeze-dried to obtain Centella asiatica extract.
[0015] Preferably, the weight ratio of cellulase, hemicellulase, and pectinase is 5:3:2.
[0016] By adopting the above technical solution, this application first treats defatted Centella asiatica powder with cellulase to make its effective substances more easily permeate and be extracted, and then uses alkaline protease to enzymatically hydrolyze it. The resulting Centella asiatica extract has a better anti-inflammatory effect compared with other extraction methods.
[0017] More preferably, the preparation method of the peony root bark extract is as follows:
[0018] B1. Mix peony root bark powder with water, add cellulase, pectinase and amylase, and extract by ultrasonication to obtain a mixture.
[0019] B2. The mixture was fractionally extracted using ethanol and ethyl acetate. After extraction, the mixture was sequentially filtered, concentrated under vacuum, and freeze-dried to obtain the peony root bark extract.
[0020] The specific steps of the fractional extraction are as follows: Ethanol and ethyl acetate are added to the mixture, keeping the initial volume fraction of ethanol and ethyl acetate at 90%. Each ultrasonic treatment lasts for 10 minutes. Water is added to dilute the mixture, reducing the volume fraction of ethanol and ethyl acetate by 10%. After ultrasonic treatment for 60 minutes, the fractional extraction is completed.
[0021] By adopting the above technical solution, compared with solvent extraction of a single concentration, this application adopts a graded extraction method, that is, using solvents of different concentrations to extract the effective substances, so that the effective substances in the peony root bark extract are fully dissolved, thereby obtaining an extract with outstanding anti-inflammatory effects. Moreover, the preparation method provided by this application is easy to operate, easy to implement, and can be mass-produced.
[0022] This application also provides the use of an anti-inflammatory and repairing composition in cosmetics.
[0023] This application also provides a facial cleanser comprising the above-described anti-inflammatory and repairing composition, surfactant, and excipients.
[0024] Preferably, the anti-inflammatory and repairing composition accounts for 1-3% of the facial cleanser by mass.
[0025] Preferably, the surfactant includes stearic acid, palmitic acid, and sodium methyl cocoyl taurate.
[0026] Preferably, the excipients include at least one of humectants, antioxidants, emollients, and preservatives.
[0027] In summary, this application has the following beneficial effects:
[0028] The main anti-inflammatory components of Centella asiatica extract and Paeonia suffruticosa root bark extract are asiaticoside and paeonol, respectively, and their combination exhibits a good synergistic anti-inflammatory effect. In addition, Centella asiatica extract and Paeonia suffruticosa root bark extract also contain other ketones, phenols, and glycosides with anti-inflammatory effects. The composition provided in this application can promote the secretion of anti-inflammatory factors that repair the skin barrier by skin cells and inhibit the expression of inflammatory factors IL-1α and IL-6 to exert anti-inflammatory effects. The composition provided in this application uses a combination of Centella asiatica extract and Paeonia suffruticosa root bark extract to achieve anti-inflammatory and skin-repairing effects through different mechanisms of action. Furthermore, the combination of the two has a synergistic anti-inflammatory effect, showing promising application prospects in cosmetics. Detailed Implementation

[0097] Performance testing
[0098] The anti-inflammatory repair compositions prepared in the above embodiments and comparative examples were tested for anti-inflammatory effects at a concentration of 1%.
[0099] I. Inhibition test of pro-inflammatory factor IL-1α:
[0100] Test system: Raw264.7 macrophages (mouse macrophage line), purchased from the Cell Bank of the Chinese Academy of Sciences.
[0101] Reagents: High glucose DMEM culture medium (Gibco), fetal bovine serum (Sijiqing), PBS (Boster), MTT (Sigma), DMSO (Sigma), trypsin (GIBCO), LPS (Sigma), dexamethasone (National Institutes for Food and Drug Control), Mouse IL-1α kit (Abcam).
[0102] Test method: according to 6.4×10 5 Cells were seeded into 6-well plates at a seeding density of cells / well and incubated overnight in an incubator (37°C, 5% CO2). The compositions prepared according to the above examples and comparative examples (diluted to 1% by mass with water as solvent) were administered, and the results were detected using ELISA.
[0103] Drug administration: When the cell deposition rate in the 6-well plate reaches 40%-60%, the cells are administered to groups of 1.8 mL each, with 3 replicates per group. The cells are then incubated in an incubator (37℃, 5% CO2) for 2 hours.
[0104] LPS stimulation: After 2 hours of incubation, 200 μL of LPS working solution prepared from the corresponding test substance working solution was added to each well plate that had been drug-treated. The well plates were shaken left and right to mix the drug in the well plates. The final concentration of LPS was 1 μL / mL. The plates were then incubated in an incubator (37℃, 5% CO2) for another 22 hours.
[0105] Sample collection: After incubation, collect the cell culture supernatant into EP tubes. After collection, freeze the samples at -80°C.
[0106] IL-1α content detection: The Mouse IL-1α kit was used for detection.
[0107] The test results are recorded in Table 2 below.

[0114] Compared with the negative group, the IL-1α secretion level in the positive group was significantly reduced, indicating that this experiment was effective.
[0115] Compared with the negative control group, the IL-1α secretion in Examples 1-11 was significantly reduced, indicating that the scalp care essence prepared in this application has a good anti-inflammatory effect. The compositions in Examples 1-6, which are obtained by compounding Centella asiatica extract and Paeonia suffruticosa root bark extract prepared in Examples 1 and 4 respectively, have a better anti-inflammatory effect than Examples 7-11. Moreover, the anti-inflammatory effect is best when the compounding ratio of the two is 1:0.8, that is, Example 4 is the optimal example.
[0116] II. Concentration Test of the Composition: The anti-inflammatory repair composition prepared in Example 4 was used as the test sample. The IL-1α inhibition rate was tested at concentrations of 0.5%, 1%, 2%, 3%, and 4%, respectively. The test results are recorded in Table 3 below.
