Description

Technical Field

[0001] The present invention belongs to the field of cosmetics, and particularly relates to a composition with oil control, acne removal, and barrier repair effects and its application. Background Art

[0002] In recent years, with the continuous development of dermatology and cosmetics science, the application of natural extracts in skin care products has become increasingly widespread, aiming to achieve multiple effects such as oil control, acne removal, and skin barrier repair. However, there are still some deficiencies in existing skin care technologies in these aspects. For example, acne removal and oil control products containing acids can accelerate epidermal metabolism and promote keratin exfoliation, but improper use of acid components may lead to problems such as thinning of the skin cutin layer, dry desquamation, and damaged skin barrier. Another example is that although vitamin B6 has advantages such as antioxidant, anti-inflammatory, regulating immune function and sebum secretion, improving skin barrier, preventing various skin inflammations, and treating acne, its problems such as easy oxidation, poor stability, low skin absorption rate, and difficulty in using in oil-soluble formulations limit its actual application effect. Therefore, exploring more gentle and effective methods for oil control, acne removal, and barrier repair, as well as developing new natural extracts or their compositions, has important practical significance for improving skin problems. Summary of the Invention

[0003] The present invention provides a composition with oil control, acne removal, and barrier repair effects and its application, which achieves the effects of oil control, acne removal, and barrier repair through the compounding of the extract of Wikstroemia exigua, the extract of Hibiscus sabdariffa L. flower, piperitone, and the extract of Cryptomeria fortunei Hooibrenk ex Otto et Dietr. buds.

[0028] Compared with the prior art, the beneficial effects of the present invention are:

[0029] In the composition provided by the present invention, the extract of Garcinia hombroniana Pierre leaves, the extract of Hibiscus sabdariffa L. flowers, totarol, and the extract of Cryptomeria japonica D. Don buds have a synergistic effect in controlling oil and treating acne and repairing the skin barrier. Among them, the extract of Garcinia hombroniana Pierre leaves can reduce the number of pores and shrink pores by inhibiting the differentiation of sebaceous gland cells and reducing sebum secretion. At the same time, it can evenly brighten the skin tone and smooth the skin texture, helping to comprehensively improve the skin condition. The extract of Hibiscus sabdariffa L. flowers can inhibit sebum secretion from the root by promoting the production of histone D and exfoliating keratotic plug protein, reducing the number of blackheads, and making the pores of the skin delicate. At the same time, it inhibits inflammatory factors, reduces the rate of inflammatory cascade reaction, combats inflammation and conditions acne-prone skin, and enhances the skin gloss. Totarol can effectively inhibit the growth of Propionibacterium acnes and Staphylococcus aureus, and has the effects of regulating sebum secretion, reducing pore blockage and inflammatory pigmentation. The anti-inflammatory and antioxidant properties of the extract of Cryptomeria japonica D. Don buds can indirectly promote the repair of the skin barrier. These four raw materials act through different mechanisms to synergistically improve skin problems and provide a comprehensive care plan for oily, acne-prone skin and skin with damaged barriers.

[0054] Safety test

[0055] Taking the "Technical Specifications for Cosmetics Safety (2015)" as the reference standard, the safety evaluations of Emulsion 1 - Emulsion 5 were carried out on 30 people aged 16 - 65 years old, and skin patch tests were conducted.

[0056] Test method: Put the test substance into the patch tester, with a dosage of 0.020 - 0.025 g. Cover the patch tester with the test substance on the back or the flexor side of the forearm of the subject with a non - irritating cloth - based tape, and gently press it with the palm to make it evenly adhere to the skin surface for 24 hours. Observe the skin reaction 30 minutes after removing the test patch tester, after the indentation disappears. If the result is negative, observe again at 24 hours and 48 hours after the patch test respectively.

[0057] Evaluation criteria:

[0058] Grade 0: Negative reaction;

[0059] Grade 1: Suspected reaction, only slight erythema;

[0060] Grade 2: Weak positive reaction, erythema, infiltration, edema, and may have papules;

[0062] Grade 4: Extremely strong positive reaction, obvious erythema, severe infiltration, edema, confluent herpes, and the reaction exceeds the test area.

[0063] Test results: The skin reactions of all subjects were negative.

[0064] The above - mentioned test results show that the emulsion provided by the present invention with the functions of oil control and acne removal and barrier repair is mild and non - irritating to the skin and is safe to use.

[0065] Efficacy test

[0066] 1. Oil - control efficacy evaluation test

[0067] Test samples: Composition 1 - 3, ① - ⑤, blank group.

[0068] Preparation of test samples: Use deionized water to prepare a mixed solution with a concentration of 7 wt% of Composition 1 - 3, ① - ⑤. The blank group only contains deionized water, and it is prepared and used immediately.

[0069] Sample dosage: 2.0 ± 0.1 mL / cm 2 。

[0070] Test method: Refer to the test method for the oil - control efficacy of cosmetics in T / ZHCA002 - 2018.

[0071] Test instrument: Sebumeter

[0072] Test time point: 4 h.

[0073] Test parallelism: 3.

[0074] Test results: Expressed as mean ± standard deviation.

[0075] Calculation method, skin oil inhibition rate = [(C 4 - C 0 ) - (T 4 - T 0 ) / (C 4 - C 0 )] × 100%

[0076] Where C 4 is the skin oil content after 4 hours in the blank group; C 0 is the initial skin oil content in the blank group; T 4 is the skin oil content after 4 hours in the sample group, and T 0 is the initial skin oil content in the sample group.

[0077] Table 2 Oil-control efficacy evaluation test

[0078] Test group Skin oil inhibition rate / % Composition 1 53.33±0.74 Composition 2 49.96±1.27 Composition 3 52.28±0.52 Composition ① 32.53±0.81 Composition ② 22.29±1.04 Composition ③ 31.32±0.93 Composition ④ 37.15±0.74 Composition ⑤ 43.04±0.41

[0079] From the results of Compositions 1-3, it can be seen that the compositions provided by the present invention have good oil-control effects. Among them, Composition 1 has the best oil-control effect.

[0080] By comparing the results of Composition 1 with those of Compositions ①-④ in the present invention, it can be seen that when any one of the extracts of Garcinia esculenta, Hibiscus sabdariffa flower, tosylphenol, and Cryptomeria japonica buds is missing, the oil-control effect of the composition becomes worse. This may be because the extract of Garcinia esculenta can inhibit the activity of aminopeptidase, thereby inhibiting the differentiation of precursor sebaceous gland cells and the secretion of oil by mature sebaceous gland cells, regulating the expression of genes related to sebum production, and thus reducing the synthesis of sebum; while the extracts of Hibiscus sabdariffa flower and tosylphenol can regulate the skin pH, inhibit the growth of bacteria on the skin surface, and reduce the excessive secretion of oil caused by bacterial activity; the flavonoids, natural polyphenols, and amino acids in the extracts of Hibiscus sabdariffa flower and Cryptomeria japonica buds can provide protection for the skin, reduce the stimulation of the skin by external environmental factors, and thus reduce the excessive secretion of oil. The four work together synergistically to reduce skin oil secretion through multiple pathways.

[0081] By comparing the results of Composition 1 with those of Composition ⑤, it can be seen that when the dosage ratio of the extracts of Garcinia esculenta, Hibiscus sabdariffa flower, tosylphenol, and Cryptomeria japonica buds in the present invention is within the defined range, the oil-control effect of the composition is the best.

[0082] Acne-removing efficacy evaluation test

[0083] Acne is a chronic inflammation of the hair follicles and sebaceous glands. The excessive secretion of lipids and blocked horny plugs in the hair follicles provide a suitable growth environment and nutrient source for anaerobic and lipophilic Propionibacterium acnes, enabling it to proliferate excessively and form a biofilm. In this state, the drug resistance of the microorganism and its pathogenicity to the body both increase significantly. Therefore, by detecting the inhibitory effect on the biofilm viability of Propionibacterium acnes after adding the cosmetic, the acne-removing efficacy of the cosmetic is evaluated. The lower the biofilm viability (dc) value, the better the acne-removing efficacy.

[0084] Preparation of test samples: Use sterile distilled water to prepare the mixtures of Compositions 1 - 3 and ① - ⑤ into a mixed solution with a concentration of 7 wt%.

[0085] Test method: Refer to the Test Method for Evaluating the Acne-Removing Efficacy of Cosmetic Raw Materials T / LNPC 018 - 2024.

[0086] Biofilm construction: Inoculate Propionibacterium acnes on the slant. After culturing for 24 h, add sterile normal saline to prepare a bacterial suspension with a bacterial concentration of 1×10 8 CFU / mL. Then add it to the RCM medium at an inoculation amount of 2%. The blank control group is not inoculated with Propionibacterium acnes and only adds the RCM medium. After mixing evenly, inoculate it into a 96-well plate and anaerobically culture at 37°C until the biofilm is formed.

[0087] Drug administration test:

[0088] Set up a blank control group, a model control group, and a test sample group. Dilute the test sample twofold with the RCM medium. Discard the medium in the original 96-well plate and add the diluted test sample, 200 μL per well. The model control group and the blank control group only add the RCM medium, 200 μL per well, and continue to culture for 24 h.

[0089] Determination of samples:

[0090] After culturing for 24 h, discard the medium, add resazurin reagent, incubate at 37°C for 1 h, and detect the biofilm viability.

[0091] Biofilm viability detection method:

[0092] Measure the fluorescence intensity I at an excitation wavelength of 560 nm and an emission wavelength of 590 nm, and calculate the relative biofilm viability.

[0093] Test parallelism: 3.

[0094] Test results: Expressed as mean ± standard deviation.

[0095] Calculation method of relative biofilm viability (dc), dc = [(I 试 - I 空 ) / (I 模-I 空 )]×100%

[0096] wherein dc is the relative viability of the biofilm; I 试 is the fluorescence intensity of the test sample group; I 空 is the fluorescence intensity of the blank control group; I 模 is the fluorescence intensity of the model control group.

[0098]

[0099]

[0100] Note: "*" indicates p < 0.05 compared with the model control group.

[0101] Comparing the results of the composition with those of the model control group, it can be seen that the composition can effectively reduce the viability of Propionibacterium acnes biofilm.

[0102] Comparing the results of Compositions 1-3, it can be seen that Composition 1 has the best effect on reducing the viability of Propionibacterium acnes biofilm.

[0103] Comparing the results of Composition 1 with those of Compositions ①-④, it can be seen that when any one of the extracts of Garcinia esculenta leaves, Hibiscus sabdariffa flowers, tosylhydrazone, and Cryptomeria japonica buds is missing, the acne treatment effect of the composition becomes worse. This may be because the extracts of Garcinia esculenta leaves and Hibiscus sabdariffa flowers can inhibit the adhesion and growth of bacteria; while tosylhydrazone can directly damage the cell membrane of bacteria and kill bacteria; the extract of Cryptomeria japonica buds can enhance the antibacterial effect, reduce the viability of bacteria by inhibiting the formation of bacterial biofilm. There is a synergistic effect among the extracts of Garcinia esculenta leaves, Hibiscus sabdariffa flowers, tosylhydrazone, and Cryptomeria japonica buds in the present invention.

[0104] Comparing the results of Composition 1 with those of Composition ⑤, it can be seen that when the dosage ratio of the extracts of Garcinia esculenta leaves, Hibiscus sabdariffa flowers, tosylhydrazone, and Cryptomeria japonica buds is within the range defined in the present invention, the composition has the best effect on reducing the viability of Propionibacterium acnes biofilm.

[0105] Barrier Repair Efficacy Evaluation Test

[0106] TEWL (transepidermal water loss), also known as percutaneous water loss, represents the evaporation loss of water in the deep dermis through the epidermis and is an important parameter for describing the skin barrier. The higher the TEWL value, the more water is lost through the skin, and the worse the skin barrier function.

[0107] Test samples: Compositions 1-3, ①-⑤, blank control group.

[0108] Preparation of test samples: Use deionized water to prepare a mixed solution with a concentration of 7 wt% from Compositions 1-3 and ①-⑤. The blank control group only contains deionized water, and it should be prepared immediately before use.

[0109] Sample dosage: 2.0 ± 0.1 mL / cm 2 。

[0110] Method of using the sample: Take a specified amount of the sample and evenly apply it to the test area using latex finger cots.

[0111] Selection criteria for volunteers' skin: According to the relevant regulations in the "Technical Specifications for Health Food Inspection and Evaluation" (2003 Edition) for the test method of improving skin moisture function, female subjects aged 18-45 years are selected on a voluntary basis. Exclusion criteria for subjects: ① Pregnant or lactating women, and those with allergic constitutions; ② Subjects with combined cardiovascular, liver, kidney, hematopoietic system diseases and mental illnesses; ③ Those who have taken items related to the test sample in the short term and affect the judgment of the results; ④ Those who have not taken the sample according to the test requirements or have dropped out midway, and whose efficacy cannot be determined or whose data are incomplete, affecting the judgment of efficacy or safety.

[0112] Test method: Select 90 volunteers aged 18-45 years for a human efficacy test, with an equal number of men and women. The volunteers are randomly divided into 9 groups, with an equal number of men and women in each group. The skin of the subjects meets the skin selection criteria. Draw a test area of 5×5 cm 2 on the inner side of the right forearm of the subjects. Establish a barrier damaged model by repeatedly peeling off adhesive tape in the test area (Judgment of the damaged model: A TEWL value of 17-29 indicates successful construction of the skin barrier damaged model). Use the test samples to evenly apply to the test area of the model every day. Use the test probe TEWAMETER TM 300 to measure the skin water loss before using the test sample for 1 day (Day 0) and on the 28th day after using the sample. Measure 5 times each time to obtain the average value. The change in water loss reflects the change law of water loss in the test area over time during the test period. TEWL change rate = (Water loss on the 28th day - Water loss on Day 0) / Water loss on Day 0. The smaller this value is, the less the water loss, and the stronger the improvement effect of the test sample on the skin barrier function. During the test period, the subjects should not apply any other cosmetics to the test area. Test results: Expressed as the average value ± standard deviation, and the results are shown in Table 4.

[0115] Note: "*" indicates p < 0.05 compared with the blank control group.

[0116] Comparing the results of the composition with those of the blank control group, it can be seen that the composition provided by the present invention can effectively repair the skin barrier.

[0117] Comparing the results of Compositions 1-3, it can be seen that Composition 1 has better skin barrier repair efficacy.

[0118] Comparing the results of Composition 1 with those of Compositions ①-④, it can be seen that when any one of the extracts of Garcinia esculenta leaves, Hibiscus sabdariffa flowers, tosyl chloride, and Cryptomeria japonica buds is missing, the barrier repair effect of the composition becomes worse. This may be because the extracts of Garcinia esculenta leaves and Hibiscus sabdariffa flowers can provide a moisturizing effect and enhance the skin's barrier function; the antibacterial property of tosyl chloride can reduce the risk of skin infection; and the anti-inflammatory property of Cryptomeria japonica buds can reduce skin irritation and redness. The four work together to provide more comprehensive skin protection.

[0119] Comparing the results of Composition 1 with those of Composition ⑤, it can be seen that when the dosage ratio of the extracts of Garcinia esculenta leaves, Hibiscus sabdariffa flowers, tosyl chloride, and Cryptomeria japonica buds in the present invention is within the range defined in the present invention, the composition has the best repair effect on the skin barrier.
