Description

Technical Field

[0001] The invention relates to the technical field of cosmetics, and particularly relates to a facial mask containing an extract of Amomum villosum with anti-aging effects and a preparation method thereof. Background Art

[0002] As people's living standards continue to improve, everyone is more and more concerned about their skin health. As the largest organ of the human body, the skin will show various signs of aging, such as wrinkles, spots, and sagging, once it reaches a certain age. Aging is not only a natural process, but also a direct manifestation of the slowing of human functions. It is generally believed that the factors that cause skin aging mainly include internal factors and external factors. Internal factors include: genetic factors, that is, the order of chromosome polymerization reactions caused by genetic inheritance will change with age; hormone shortage, that is, hormone aging due to hormone deficiency, such as estrogen deficiency will lead to reduced function of skin connective tissue, thereby causing various skin changes. External factors include: pollution factors, that is, the pollution caused by the growing exhaust gas and various pollutants in the atmosphere will form a large number of free radicals. The attack of free radicals will cause skin cell death and rapid aging, such as skin suffocation, pore blockage, and skin fragility; photoaging, that is, the accumulation of UVA / UVB rays will produce harmful effects on the skin, such as dermal tissue disorder, thinning of the epidermal dermal connective tissue that controls skin fine-tuning, etc. In addition, excessive exposure to ultraviolet rays is also the main cause of premature aging symptoms on facial skin.

[0003] In recent years, with the continuous emergence of various daily chemical products, anti-aging skin care products have become a hot spot in market demand. People's attention to skin conditions has gradually increased. However, traditional anti-aging skin care products usually achieve their functions by adding artificial antioxidant ingredients, but these ingredients may cause skin sensitivity and other problems. Driven by concepts such as natural and herbal, natural plant skin care products have become an important direction for market research and development due to their wide sources, low prices, low irritation, safety and effectiveness. Natural plant skin care products use plant extracts to provide mild antioxidant and anti-inflammatory effects to help improve skin conditions. This trend not only meets consumers' demand for safety and effectiveness, but also drives the skin care industry to develop in a more natural and environmentally friendly direction.

[0004] Tsaoko is a herbaceous plant of the genus Cardamom in the ginger family, also known as grass fruit, grass fruit kernel, and old cardamom. Its shape is oblong, the fruit is purple-red when fresh, and brown after drying. The skin of the dried fruit has longitudinal wrinkles. After peeling off the shell, it can be seen that there are three petals inside, and most of them have 8 to 10 seeds in each petal. As a traditional Chinese medicine and spice, the production of tsaoko in China accounts for more than 80% of the world's total. The main components of the tsaoko extract obtained by steam distillation extraction using gas chromatography-mass spectrometry are 1,8-cineole, α-pinene, camphor, pineneol, geraniol, and nerolidol. Among them, 1,8-cineole can be antibacterial and antiviral, α-pinene can relieve cough and expectorant, inhibit bacteria and kill insects, camphor can refresh the mind, and pineneol, geraniol, nerolidol, etc. have significant antibacterial and sedative effects. Amomum villosum extract has very good important biological activities such as antioxidant, anti-inflammatory, antibacterial, anti-tumor, antiviral, and lipid metabolism regulation. Amomum villosum is a plant that is both medicinal and edible. As a spice, more than 90% of it is used as a seasoning for food, and less than 5% of its output is used in the preparation of traditional Chinese medicines and other fields. Amomum villosum extract and amomum villosum medicinal extract have been added to the Catalogue of Used Cosmetic Raw Materials (2021 edition).

The same reference numerals indicate the same parts in all the drawings. The drawings are not drawn to scale, and emphasis is placed on illustrating the subject matter of the present invention.

[0033] Figure 1 This is a comparison chart of type I collagen content in the 0.3% amomum villosum extract group, 0.2% amomum villosum extract group, 0.1% amomum villosum extract group, 1% bosacein group and the model control group. DETAILED DESCRIPTION

[0034] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0035] The following examples and comparative examples were used to determine the DPPH scavenging ability:

[0036] Prepare a 40 mg / L DPPH solution.

[0037] Determination of reference substance: 1 mL of sample solution and 9 mL of DPPH solution were placed in a test tube. After rapid mixing, the tube was placed away from light and its absorbance was measured at 517 nm every 10 min.

[0038] Calculate the scavenging rate of the sample for DPPH·:

[0039] .

[0040] Example 1

[0041] A method for preparing an extract of Amomum villosum, comprising the following steps:

[0042] S1. Processing of the cardamom: picking fresh cardamom, drying the cardamom naturally in the sun, washing, crushing and sieving the dried cardamom to obtain cardamom powder;

[0043] S2. Preparation of Amomum villosum extract: The Amomum villosum powder in step S1 is pre-soaked for 65 minutes, and then subjected to ultrasonic-assisted distillation. The obtained oil-water mixture is allowed to stand for stratification, and the upper layer of oil is taken. Water is removed to obtain the Amomum villosum extract. The conditions for ultrasonic-assisted distillation are: ultrasonic time: 30 minutes, ultrasonic power: 125 W. The conditions for steam distillation are: solid-liquid ratio of 1:10, distillation time: 4 hours, distillation temperature: 120°C, and oil bath rotor speed: 800 rpm.

[0044] The DPPH scavenging ability test results of the Amomum villosum extract and the control group are shown in Table 1.

[0045] Table 1

[0046]

[0047] It can be seen from Table 1 above that the Amomum villosum extract prepared in Example 1 of the present invention has good antioxidant activity.

[0048] The characteristics of skin aging include the aging of fibroblasts in the dermis and the degradation of the extracellular matrix. Reactive oxygen species (ROS) are a class of highly reactive chemicals produced during cell metabolism. They play an important role in signal transmission within cells, but excessive ROS can cause oxidative stress, which in turn affects cell structure and function. According to reports, ROS can stimulate cells to produce matrix metalloproteinases (MMPs), which degrade important collagen and elastin in the dermis, which is one of the causes of skin aging, sagging and wrinkles. This application intends to evaluate whether the sample has anti-aging effects by detecting the ROS clearance rate in human dermal fibroblasts after UVA radiation;

[0049] Using N-acetyl-L-cysteine ​​as a control group, the Amomum villosum extract was tested. The specific test method is as follows:

[0050] 1. Inoculate human skin fibroblasts into 12-well plates (5×104 cells / well) and incubate at 37°C, 5% CO2 for 24 hours.

[0051] 2. Sample administration: Remove the culture medium and gently rinse the cells once or twice with D-Hanks. Replace the culture medium with fresh medium for the normal control group and the model control group, and replace the culture medium with fresh medium containing diluted 0.3%, 0.2%, 0.1% of Amomum villosum extract or fresh medium containing diluted 0.3%, 0.2%, 0.1% of N-acetyl-L-cysteine ​​for the sample group, and continue to incubate at 37°C, 5% CO2 for 24 h.

[0052] 3. Modeling: After the incubation, the culture medium was removed, the cells were gently rinsed once or twice with D-Hanks, and then the modeling treatment was performed. The model control group and the sample group were irradiated with UVA (5 J / cm 2 ), and the normal control group was placed in the dark.

[0053] 4. After the modeling is completed, the cells are stained with the reactive oxygen species detection kit, photographed with a fluorescence microscope, and the average fluorescence intensity (S) of each group of cells is analyzed by ImageJ, and the ROS clearance rate of the sample group is calculated according to the formula.

[0054] The test results are shown in Table 2.

[0055] Table 2

[0056]

[0057] As shown in Table 2 above, the Amomum villosum extract prepared by the present invention has good antioxidant activity. It was observed that the average fluorescence intensity of ROS in the Amomum villosum extract group was significantly weakened compared with the model control group, revealing that the sample has an anti-aging effect.

[0058] Fibroblasts are the main target cells that synthesize and secrete collagen and elastin, and produce extracellular matrix components such as collagen fibers, reticular fibers, elastic fibers, glycosaminoglycans and glycoproteins. Type I collagen is one of the main components of the extracellular matrix of the dermis. It is synthesized by dermal fibroblasts in the cells as type I procollagen and secreted outside the cells. Under the action of terminal procollagen peptidase, the terminal peptides are separated and polymerized to form collagen fibers. With age, the type I collagen in the skin will gradually decrease, which will cause the skin to lose elasticity and firmness, resulting in signs of aging such as wrinkles and sagging. The synthesis of collagen is affected by many factors, including age, ultraviolet radiation, unhealthy lifestyles, etc. This application intends to evaluate whether the sample has anti-aging effects by detecting the upregulation rate of type I collagen content in human dermal fibroblasts after UVA radiation.

[0059] Using Bossagra as a control group, the Amomum villosum extract was tested. The specific test method is as follows:

[0060] 1. Inoculate human skin fibroblasts into 96-well plates (2×104 cells / well) and incubate at 37°C, 5% CO2 for 24 h.

[0061] 2. Modeling: After incubation, remove the culture medium, wash with D-Hanks 1-2 times, and then irradiate the sample group and model control group with UVA (5 J / cm 2 ), while the normal control group was placed in the dark.

[0062] 3. The normal control group and model control group were replaced with fresh culture medium, and the sample group was replaced with fresh culture medium containing 0.3%, 0.2%, 0.1% of Amomum villosum extract or 1% of Bosnerin, and incubated at 37°C, 5% CO2 for 24 h.

[0063] 4. Collect 200 μL of cell culture supernatant from each well, detect the type I collagen content by ELISA, and calculate the upregulation rate using the following formula.

[0064]

[0065] The test results are shown in Table 3.

[0066] Table 3

[0067]

[0068] Figure 1 That is, the comparison of type I collagen content in the 0.3% Amomum villosum extract group, 0.2% Amomum villosum extract group, 0.1% Amomum villosum extract group, 1% Bosin group and the model control group. Figure 1 It can be seen that the type I collagen content in the 0.3% amomum villosum extract group, 0.2% amomum villosum extract group, and 0.1% amomum villosum extract group was significantly increased compared with the model control group, revealing that the sample has anti-aging effects.

[0069] The type I collagen content in the 0.3% amomum villosum extract group, 0.2% amomum villosum extract group, 0.1% amomum villosum extract group and 1% bosoniain group were all significantly increased, but the cost of bosoniain raw materials is too high. Amomum villosum extract can achieve similar effects at extremely low concentrations and costs, and amomum villosum extract is extracted from nature. Therefore, the use of amomum villosum extract as an active ingredient in the development of anti-aging products has great application prospects.

[0070] Example 2

[0071] A method for preparing a facial mask containing an extract of Amomum villosum with anti-aging effects comprises the following steps:

[0072] (1) Add 0.1wt% sodium hyaluronate, 1wt% carbomer, 0.7wt% allantoin, 0.1wt% disodium EDTA, 8wt% glycerol and 6wt% butylene glycol into 80wt% deionized water, stir until there is no insoluble matter, heat to 75°C, and keep warm for 20 minutes to obtain phase A;

[0073] (2) Premix 2 wt% betaine and 0.1 wt% caprylyl glycol to form phase B, add phase B into phase A cooled to below 50°C and stir until no insoluble matter is left;

[0074] (3) Add 1 wt % of the Amomum villosum extract prepared in Example 1 and 1 wt % of PEG-40 hydrogenated castor oil to the mixture, emulsify, filter using a filter cloth with a mesh size of 400 or more, and discharge the mixture to obtain an Amomum villosum extract facial mask having anti-aging effects.

[0075] Embodiments 3 to 8

[0076] A method for preparing a facial mask containing an extract of Amomum villosum with anti-aging effects is basically the same as Example 2, except that the amount of raw materials added is as shown in Table 4 below, where A, B, C, D, E, F, G, H, I, J and K respectively represent sodium hyaluronate, carbomer, allantoin, disodium EDTA, glycerin, butylene glycol, deionized water, betaine, caprylyl glycol, Amomum villosum extract and PEG-40 hydrogenated castor oil, and the units are weight percentages.

[0077] Table 4

[0078]

[0079] The tsaoko extract facial masks prepared in Examples 2 to 8 were subjected to DPPH free radical scavenging tests, and the test results are shown in Table 5 below;

[0080] Table 5

[0081]

[0082] After comprehensive evaluation, the effect achieved by Example 8 is relatively the best.

[0083] From the perspective of antioxidant performance (characterized by DPPH free radical scavenging ability), the DPPH scavenging ability of Example 8 reached 91.13±0.28, which is at a relatively high level, indicating that its antioxidant effect is significant. Free radicals are one of the important factors leading to skin aging. High free radical scavenging ability means that the mask can effectively fight skin oxidative stress, reduce free radical damage to skin cells, and thus delay the aging process of the skin, such as reducing wrinkle formation and maintaining skin elasticity.

[0084] In terms of moisturizing, the content of sodium hyaluronate in Example 8 is set to 0.2wt%, which is a certain degree of optimization and improvement compared with other examples. With its unique molecular structure and physical and chemical properties, this ingredient can quickly hydrate on the skin surface and interweave to form a more durable, stable and highly hydrophilic moisturizing film. The content of butylene glycol in Example 8 is as high as 6.55wt%. This high proportion configuration not only further consolidates the moisturizing foundation of the mask and strengthens the hydration of the skin, but also gives the mask liquid excellent fluidity and ductility.

[0085] In terms of soothing, the content of allantoin added in Example 8 is up to 0.8wt%, which gives the mask an extraordinary ability to soothe the skin. Whether it is the sensitivity and discomfort encountered by the skin during the season change, the stinging sensation caused by a slight sunburn, or the itching symptoms caused by contact with external adverse substances, allantoin can play a role quickly and accurately. The content of betaine in Example 8 is 1.0wt%, and its moisturizing and anti-irritation properties are extreme. On the one hand, as a highly efficient natural moisturizing factor, it can continuously replenish moisture for the skin and maintain the hydration balance of the skin; on the other hand, with its unique zwitterionic structure, betaine can form a protective layer with dynamic buffering capacity on the skin surface, effectively resisting physical, chemical and biological multi-source stimulation factors from the external environment.

[0086] In summary, Example 8 demonstrates unparalleled excellent performance in various key technical indicators and application dimensions such as free radical scavenging ability, moisturizing, soothing, anti-aging, and comfort of use, providing top-level skin care solutions in all aspects, and can fully meet consumers' stringent demands for a high-quality, multi-functional facial mask.
