Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cosmetics, in particular to a male-specific oil control and repair composition containing Norwegian spruce leaves and application thereof. BACKGROUND

[0002] Technical analysis shows that male skin has significant physiological differences compared to female skin, mainly in the following aspects: (1) physiological structure difference: the thickness of the stratum corneum of male skin is increased by about 20-25% compared to female skin, the epidermal tissue structure is more dense, the collagen fiber density of the dermis layer is high, and the sebaceous gland volume is increased by 3-4 times compared to female skin. This structural feature leads to a generally higher surface roughness index of male skin than female skin. (2) Metabolic regulation mechanism difference: the distribution density of androgen receptors in male sebaceous gland cells is 2-3 times higher than that of females, and most of the sebaceous secretion of men is stimulated by testosterone. Testosterone is converted to dihydrotestosterone (DHT) under the action of 5α-reductase, and the activity of DHT is 5-10 times that of testosterone. DHT can bind to intracellular androgen receptors to stimulate sebaceous gland secretion. (3) Barrier function difference: shaving behavior leads to damage to the integrity of the stratum corneum, and the transepidermal water loss rate (TEWL) is increased compared to the unshaved area. At the same time, the amount of sweat gland secretion is significantly higher than that of women, and the lactic acid / urea complex in sweat reduces the pH value of the skin surface, accelerates the emulsification and diffusion speed of sebum, and makes sebum more easily distributed on the face, making the skin more oily and more prone to bacterial growth.

[0003] The existing oil control and repair products mainly have the following technical defects: (1) The cleaning type product excessively relies on surfactants (such as sodium lauryl sulfate, SLS), and the high degreasing index of which leads to an increase in the loss rate of natural ceramide in the sebum film, causing a compensatory increase in sebaceous secretion; (2) Adsorbent ingredients (such as diatomite, kaolin) can temporarily reduce the oil content on the skin surface, but they form a physical occlusive layer that promotes the proliferation of Propionibacterium acnes; (3) The existing formula system fails to specifically regulate the activity of 5α-reductase and has no substantial intervention effect on the DHT-mediated sebaceous secretion signaling pathway; (4) Excessive cleaning leads to damage to the epidermal lipid bilayer structure, an increase in the transdermal water loss value, and a "oily outside and dry inside" skin condition.

[0004] In view of the lack of effectiveness of existing products in controlling oil and the lack of barrier repair function, which may induce secondary skin problems, there is an urgent need in the art for an oil control composition that can alleviate the problem of compensatory increase in sebaceous secretion, increase the effectiveness of the product in controlling oil, and has a barrier repair function. SUMMARY

[0005] Therefore, the purpose of the present application is to overcome the deficiencies of the prior art and provide a male-specific oil control and repair composition containing Norwegian spruce leaves and application thereof, which can alleviate the problem of compensatory increase in sebaceous secretion, increase the effectiveness of the product in controlling oil, and has a barrier repair function.

[0006] To achieve the above-mentioned purpose, in the first aspect of the present application, the present application provides a Norway spruce leaf-containing oil control repair composition, which comprises the following components by weight: Norway spruce leaf extract 0.1-2 parts, Sargentodoxa cuneata extract 0.1-0.5 parts, yeast / kelp sugar fermentation product 1-5 parts, Usnea barbata extract 0.1-0.5 parts, and Hamamelis virginiana extract 0.1-2 parts.

[0007] The Norway spruce leaf extract contains rich polysaccharides, flavonoids, polyphenols and other ingredients, which can inhibit the secretion of sebaceous gland cells; triterpenoid components can improve the water and oil balance of the skin, reduce dryness and itching of the skin; in addition, inhibiting the secretion of oil may reduce inflammation to some extent, and the extract also has anti-inflammatory ingredients such as flavonoids, so it also has certain skin anti-inflammatory effect. Sargentodoxa cuneata extract can inhibit melanin production and reduce the production of inflammatory factors, and can be used in products with functions such as whitening and antibacterial. Another study pointed out through molecular docking and molecular dynamics simulation that some sesquiterpenes and flavonoids in Sargentodoxa cuneata extract can bind to androgen receptors and occupy binding sites. Therefore, the inventors speculate that adding the extract to oil control products may reduce the binding of DHT to androgen receptors, thereby reducing sebum secretion. The yeast / kelp sugar fermentation product takes advantage of the symbiotic relationship between algae and natural yeast to release nutrients in the algae. In addition to reducing sebum secretion, it can also increase the content of ceramides in the skin and improve dry and rough skin. Usnea barbata extract can make the sweat gland wall smaller to achieve the purpose of stopping sweating. The extract of the bark and leaves of Hamamelis virginiana can be used in skin care products.

[0008] The inventors found in actual experiments that the Norway spruce leaf extract, Sargentodoxa cuneata extract, yeast / kelp sugar fermentation product, Usnea barbata extract, and Hamamelis virginiana extract in the present application synergize to play a role in oil control, barrier repair, anti-inflammatory and antibacterial, maintenance of microenvironment stability, and reduction of abnormal activation of sebaceous glands, etc. They can reduce compensatory sebum secretion through a closed loop path, and also alleviate compensatory secretion through long-acting stability maintenance, which is suitable for skin that needs long-term oil control and is sensitive.

[0009] Preferably, the oil control repair composition comprises the following components by weight: Norway spruce leaf extract 1-1.5 parts, Sargentodoxa cuneata extract 0.2-0.3 parts, yeast / kelp sugar fermentation product 2-4 parts, Usnea barbata extract 0.2-0.3 parts, and Hamamelis virginiana extract 0.8-1.5 parts.

[0010] The inventor found in the actual experiment that the weight parts of each component in the composition have great influence on the oil control timeliness and barrier repair function of the final composition, and when the weight parts are within the above range, the final composition can better alleviate the problem of enhanced compensatory sebum secretion and has better barrier repair effect.

[0011] Preferably, the weight percentage content of the Hamamelis virginiana extract is 15-25% based on the total weight of the oil control repair composition.

[0012] The inventor found in the actual experiment that the weight percentage content of the Hamamelis virginiana extract in the composition also has great influence on the oil control timeliness and barrier repair function of the final composition, and when the weight percentage content of the Hamamelis virginiana extract in the composition is within the above range, the final composition can better solve the problem of enhanced compensatory sebum secretion and has better barrier repair effect.

[0013] Preferably, each extract in the present application can be a commercially available product or self-made.

[0014] Preferably, the Hamamelis virginiana extract includes bark extract and leaf extract.

[0015] The inventor found in the actual experiment that when the Hamamelis virginiana extract includes bark extract and leaf extract, the problem of compensatory secretion is alleviated and the timeliness is prolonged, the effect of instant oil control is achieved, and the barrier repair effect is better. The Hamamelis virginiana bark extract is rich in hydrolysable tannins, which can physically shrink pores and reduce the expansion of sebum discharge channels, better achieving the effect of instant oil control; on the other hand, it can significantly inhibit hyaluronidase and maintain deep moisture, avoiding excessive dryness caused by compensatory sebum secretion, achieving the effect of deep moisturizing. The Hamamelis virginiana leaf extract contains condensed tannins, which have stronger antibacterial effect. On the one hand, it can inhibit excessive sebum secretion caused by excessive proliferation of microorganisms on the skin surface; on the other hand, it also has strong anti-inflammatory effect, which can reduce sebum secretion caused by inflammatory factors. When the Hamamelis virginiana bark extract and the Hamamelis virginiana leaf extract work together, convergence and antibacterial combination reduce sebum secretion while blocking the cause of compensatory secretion.

[0016] Preferably, in the Hamamelis virginiana extract, the weight ratio of the bark extract to the leaf extract is 1:(0.5-5). Further preferably, in the Hamamelis virginiana extract, the weight ratio of the bark extract to the leaf extract is 1:(1-2).

[0017] The inventor found in the actual experiment that the weight ratio of the bark extract and the leaf extract in the Hamamelis virginiana extract further affects the oil control timeliness and the barrier repair effect, when the weight ratio of the bark extract and the leaf extract is in the above specific range, the finally obtained composition can better solve the problem of compensatory hyperseborrhoea, increase the oil control timeliness of the product, and has better barrier repair effect.

[0018] In the second aspect of the present application, the oil control and repair composition is applied to the preparation of a cosmetic.

[0019] In the third aspect of the present application, a cosmetic is provided, which comprises the oil control and repair composition.

[0020] Preferably, the cosmetic comprises any one of cosmetic water, emulsion, cream, mask, serum, essence oil, and spray.

[0021] Preferably, the cosmetic is serum, which comprises the following components by weight: 2-8 parts of the oil control and repair composition, 7-22 parts of a humectant, 0.8-1.2 parts of a preservative, and 0.04-0.06 parts of a chelating agent.

[0022] Preferably, the humectant comprises at least one of glycerol, sorbitol, and propylene glycol, the preservative comprises at least one of p-hydroxyacetophenone and hexylene glycol, and the chelating agent comprises EDTA-2Na.

[0023] Compared with the prior art, the present application has the following beneficial effects: the inventor found in the actual experiment that the Norway spruce leaf extract, the Oldenlandia diffusa extract, the yeast / sea tangle sugar fermentation product, the Usnea barbata extract, and the Hamamelis virginiana extract are synergistic, the components synergize to play effects in oil control, barrier repair, anti-inflammatory and antibacterial, microenvironment stability maintenance, and reduction of abnormal activation of sebaceous glands, can reduce compensatory hyperseborrhoea through a closed loop path, and relieve compensatory secretion through long-acting stability maintenance, and is suitable for skin that needs long-term oil control and is sensitive.

[0068] (3) Neutral lipid fluorescence quantitative experiment: ① The cell line used is human sebaceous gland cell SZ95 (Shanghai Qingqi Biology, BFN60807569), the passage number is 7, and the test conditions are: incubator temperature 37±1℃, humidity 90±5%, carbon dioxide 5±1%; the cell suspension is inoculated in a 96-well cell culture plate (black bottom transparent type), and the density of each well is 1.0*10 4(1) 2x104cells / well, 100 μL medium was added to each well, and incubated for 18-24 h; (2) the supernatant was discarded, and 100 μL of the negative control, positive control, model, and sample were added to each well according to the experimental grouping; after incubation for 48 h, the supernatant was discarded, and the cells were washed twice with PBS, 100 μL of 10 μg / mL Nile Red dye (Shanghai Yuan Ye Bioengineering, S02N11G129713) was added to the sample group, and 15 ng / mL fluorescein diacetate FDA (Shanghai Yuan Ye Bioengineering, J22A11H122040) was added to the model group, and incubated for 5 min; the released fluorescence was detected using a multifunctional enzyme marker; 485 nm and 494 nm excitation wavelengths and 565 nm and 523 nm absorption wavelengths were used to detect the fluorescence intensity of Nile Red and FDA; (3) the results were determined using the ratio of Nile Red and FDA (OD ratio); the percentage of neutral lipids in the cells (%) = sample or positive control OD ratio / model group OD ratio*100%; the improvement rate of oil secretion = (percentage of neutral lipids M - percentage of neutral lipids TA / PC ) / (percentage of neutral lipids M - percentage of neutral lipids NT ) x 100%.

[0069] (4) The test results are shown in Table 3.

[0070] Table 3

[0071]

[0072]

[0073] As shown in the above table, the oil secretion improvement rate of the composition prepared in Examples 1-10 is more than 40%, and the composition has a good oil control effect. As shown by the comparison between Examples 1-5, the weight of each component in the composition has a great influence on the oil control effect and barrier repair function of the final composition; when the weight of the Norway spruce leaf extract is 1-1.5 parts, the weight of the Sargentia cyathiformis extract is 0.2-0.3 parts, the weight of the yeast / kelp sugar fermentation product is 2-4 parts, the weight of the Usnea barbata extract is 0.2-0.3 parts, and the weight of the Hypericum canadense extract is 0.8-1.5 parts, the oil control effect is better. As shown by the comparison between Examples 1 and Examples 6-10, the type of the Hypericum canadense extract has a great influence on the oil control effect; when the Hypericum canadense extract includes bark extract and leaf extract, the oil control effect is better; when the weight ratio of the bark extract to the leaf extract is 1:(1-2), the oil control effect is best.

[0074] From the comparison of Example 1, Comparative Examples 1-5, it can be seen that when the oil control care composition lacks one component, or the total weight parts are unchanged and one component is lacking, good oil control effect cannot be achieved. From the comparison of Example 1, Comparative Examples 6-7, it can be seen that when the other part is replaced by the component in the application, good oil control effect cannot be achieved.

[0075] Performance test-2 long-term skin oil control, care, and moisturizing effect test.

[0076] Test group: products prepared in Application Examples 1-12, Comparative Application Examples 1-7, and the blank application example.

[0077] Test process: select male volunteers aged 18-45 years old with oily skin (facial oil content > 70 μg / cm 2 within 8 hours before product use). The subjects sat in a constant temperature and humidity room with a temperature of 21±1℃ and a humidity of 50±10% for 30 min. The facial initial oil content, initial moisture content, and initial TEWL value were tested using a skin oil content tester Sebumeter (SM815, Courage and Khazaka), a moisture probe CM 825 (Courage+Khazaka), and a trans-epidermal water loss probe TM Hex (Courage+Khazaka). The skin tape D-SquameTM D100 was used to stick the sebum on both cheeks of the volunteers 5 times, and after collecting the samples, quantitative lipidome sequencing was performed using the quantitative lipidome sequencer of Wuhan Maiwei Metabolic Biotechnology Co., Ltd. The ceramide-NP average content of the volunteers' skin was calculated according to the sequencing results. The subjects were randomly divided into 20 groups, with 5 people in each group, and randomly applied the corresponding products to the whole face every day. The oil content, moisture content, TEWL value, and ceramide content were tested at 28 days, and the improvement of each volunteer was analyzed. The improvement was represented by the change rate. The calculation method is as follows:

[0078] Change rate % relative to initial value = (T 清洗前 -T 28 ) / T 清洗前 *100%;

[0079] The test results are shown in Table 4.

[0080] Table 4

[0081]

[0082]

[0083] From the above table, the composition prepared by the embodiment of the present application has a ceramide increase rate of more than 15%, a TEWL value improvement rate of more than 15%, a skin moisture improvement rate of more than 25%, and a oil content improvement rate of more than 20% after being prepared into cosmetics. The Norway spruce leaf extract, the oldenlandia diffusa willd extract, the saccharomyces / codium tomentosum thuret ferment, the usnea barbata, and the hamamelis virginiana pallas extract in the present application are synergistic, have a long-term oil control effect, and have a better barrier repair effect, and are suitable for skin that needs long-term oil control and is sensitive.

[0084] From the comparison of application examples 1-5, the weight parts of each component in the composition have a greater influence on the long-term oil control effect and the barrier repair function of the final composition. When the Norway spruce leaf extract is 1-1.5 parts, the oldenlandia diffusa willd extract is 0.2-0.3 parts, the saccharomyces / codium tomentosum thuret ferment is 2-4 parts, the usnea barbata is 0.2-0.3 parts, and the hamamelis virginiana pallas extract is 0.8-1.5 parts, the long-term oil control effect and the barrier repair effect are better. From the comparison of application example 1 and application examples 6-10, the type of the hamamelis virginiana pallas extract has a greater influence on the long-term oil control effect and the barrier repair effect. When the hamamelis virginiana pallas extract includes bark extract and leaf extract, the long-term oil control effect and the barrier repair effect are better. When the weight ratio of the bark extract to the leaf extract is 1:(1-2), the long-term oil control effect and the barrier repair effect are best.

[0085] From the comparison of application example 1 and comparative application examples 1-3, when the oil control and repair composition lacks one component, the oil control effect and the barrier repair effect cannot be simultaneously satisfied. For example, comparative application example 1 lacks the Norway spruce leaf extract, although the ceramide increase rate, the TEWL value improvement rate, and the skin moisture improvement rate are good, the oil content improvement rate is less than 10%, and the oil control effect is poor. Comparative application examples 2-3 respectively lack one of the saccharomyces / codium tomentosum thuret ferment and the hamamelis virginiana pallas extract, the oil content improvement rate is less than 15%, and the oil control effect and the barrier repair effect are poor.

[0086] From the comparison of application example 1 and comparative application examples 4-5, when the oil control and repair composition lacks one component but the total weight parts are unchanged, the oil control effect and the barrier repair effect still have a large gap compared with the embodiment. From the comparison of application example 1 and comparative application examples 6-7, when other components replace part of the components in the present application, good effects cannot be achieved, and the components in the present application are synergistic.

[0087] Performance test-3 skin immediate oil control effect test.

[0088] Test group: products prepared from application examples 1, 5, 8, 9, 12, comparative application example 5, and blank application example.

[0089] Test process: 18-45-year-old oily skin (facial oil content > 70 μg / cm2 within 8 h before product use) is selected.2 Male volunteers. The average oil spot size before cleansing was tested after the subjects sat in a constant temperature and humidity room for 30 min at a temperature of 21±1℃ and a humidity of 50±10%. The face was washed with facial cleanser for 3 times (to simulate the decrease of barrier function due to long-term use of strong cleaning force products), and the skin surface texture analysis system The average oil spot size of the cheek was tested by VC 20plus (the smaller the average oil spot size index, the smaller the amount of skin oil) to obtain the initial value, i.e. the 0h experimental data. The subjects were randomly divided into 7 groups, each group of 5 people, and randomly used the oil control product provided by the present application (half-face test, the right cheek used the product prepared according to application examples 1, 5, 8, 9, 12, comparative application example 5 and blank application example, and the left cheek was not treated). The average oil spot size was tested at 2h and 4h, respectively, and the improvement of each volunteer index was analyzed, which was represented by the improvement rate.

[0090] The calculation method is as follows:

[0091] The improvement rate % of the right cheek relative to the left cheek = (T 左脸 -T 右脸 ) / T 左脸 *100%; wherein the improvement rate % of the right cheek relative to the left cheek at 2h = (T2right cheek-T2left cheek) / T2left cheek*100%, and the improvement rate % of the right cheek relative to the left cheek at 4h = (T4right cheek-T4left cheek) / T4left cheek*100%.

[0092] Test results: the average oil spot size data and the change rate data are shown in Table 5.

[0093] Table 5

[0094]

[0095]

[0096] From Table 5 and Figures 1-3 It can be seen that the composition prepared according to the present application can well alleviate the problem of increased compensatory sebum secretion and increase the oil control timeliness of the product when the composition is prepared into a cosmetic. Figure 1 is the change graph of the oil spot on the right cheek after using the blank application example; Figure 2 is the change graph of the oil spot on the right cheek after using application example 1; Figure 3 is the change graph of the oil spot on the right cheek after using comparative application example 5.

[0097] The left face of the volunteers tested in the present application is not treated at all. As can be seen from Table 5, excessive cleaning causes the epidermal lipid bilayer structure to be damaged, the sebum secretion is enhanced after 2 hours of excessive cleaning, and the sebum secretion is extremely obviously enhanced after 4 hours of excessive cleaning. The present application uses facial cleanser to clean the face for 3 times, simulates the decline of barrier function due to long-term use of strong cleaning force products, and performs a compensatory sebum secretion experiment.

[0098] As can be seen from the experimental results of the right face of Application Example 1, Application Example 5, Application Example 8, Application Example 9, and Application Example 12, the cosmetic prepared in the present application can well alleviate the compensatory sebum secretion enhancement.

[0099] As can be seen from the experimental results of Application Example 1 and Comparative Application Example 5, although the former experiment proves that Comparative Application Example 5 also has a good oil control effect, the effect of Comparative Application Example 5 in alleviating compensatory sebum secretion enhancement is poor.

[0100] Finally, it should be noted that the above examples are only used to illustrate the technical solutions of the present application and not to limit the protection scope of the present application. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced by equivalents without departing from the essence and scope of the technical solutions of the present application.
