Description

Technical Field

[0001] This invention belongs to the field of cosmetic technology and discloses an oil-controlling and fluffing composition, its uses, and daily chemical products. Background Technology

[0002] Scalp oil is mainly secreted by sebaceous glands, and its secretion is regulated by multiple factors, including genetics, hormone levels, microbial balance, mental stress, and external pollution. When oil secretion is excessive, the excess oil adheres to the scalp and hair surface, leading to problems such as greasy, flat hair, weak hair roots, and hair sticking to the scalp. This not only affects the aesthetics and durability of hairstyles but also easily clogs hair follicles and disrupts the scalp's microecological balance, resulting in secondary problems such as increased dandruff, scalp itching, and folliculitis, severely reducing consumers' quality of life and self-confidence. In an era that values ​​individuality, a clean and voluminous hairstyle has become key to enhancing image and confidence. Consumers' demands for shampoo have evolved: effective oil control combined with long-lasting volume is indispensable. People with fine or thin hair are particularly reliant on this, as their hair is prone to flattening due to oil accumulation and they are especially sensitive to greasiness; the volumizing function is directly related to improved appearance.

[0003] To meet these needs, the market has seen a surge of hair care products claiming oil-control or volumizing effects, such as oil-control shampoos, volumizing hair masks, and styling sprays. Some products rely on cleansing or physical absorption, only acting on existing oil production and failing to regulate sebaceous gland secretion at its source. This results in short-lived oil-control effects, with oil rebounding typically within 1-2 days after washing, requiring frequent cleansing and potentially irritating the scalp and exacerbating sebum secretion disorders. Other products may utilize a combination of different plant-based ingredients to achieve a volumizing effect; however, these products have complex formulas, and different ingredients may have antagonistic effects, leading to less effective results.

[0004] Therefore, the technical problem to be solved by the present invention is: how to provide a novel oil-controlling and fluffy composition with excellent oil-controlling and fluffy effects to overcome the shortcomings of existing products. Summary of the Invention

[0081] 8. Judgment Rules

[0082] (1) If the area of ​​fluffy hair strands in the test product group increases significantly after using the product compared with that before use (P<0.05), it indicates that the test product has the effect of increasing the visual hair volume;

[0083] 9. Test Results

[0084] The test results of the oil-controlling and volumizing compositions of each embodiment and comparative example are shown in Table 5, expressed as the average volumizing change rate of three hair strands; photos of one group of hair strands before and after use in each case are shown in Table 5. Figures 1-18 As shown.

[0085] Table 5. Average Loftiness Change Rate

[0086] Average loft change rate / % Photos before use Photos before use Example 1 10.05 Figure 1 Figure 2 Example 2 8.57 Figure 3 Figure 4 Example 3 9.13 Figure 5 Figure 6 Example 4 8.47 Figure 7 Figure 8 Example 5 9.62 Figure 9 Figure 10 Comparative Example 1 0.47 Figure 11 Figure 12 Comparative Example 2 3.84 Figure 13 Figure 14 Comparative Example 3 0.69 Figure 15 Figure 16 Comparative Example 4 4.11 Figure 17 Figure 18

[0087] As can be seen from the data in Table 5, the average fluffiness change rate of Examples 1 to 5 is between 8.47% and 10.05%, indicating that the oil-controlling and fluffing compositions obtained by combining olive leaf extract solution and alfalfa extract solution in a specific ratio according to the present invention have a good effect on making hair fluffy. The concentrations of Comparative Examples 1 and 2 are the same as those of Example 1, but the composition of Comparative Example 1 only contains olive leaf extract solution and lacks alfalfa extract solution, while the composition of Comparative Example 2 only contains alfalfa extract solution and lacks olive leaf extract solution. It can be seen that the average fluffiness change rate of Comparative Example 1 is only 0.47%, and that of Comparative Example 2 is only 3.84%, which is much lower than the 10.05% of Example 1. Example 1 combines the two components and only adds a small amount of olive leaf extract solution to alfalfa extract solution, and its average fluffiness change rate is greatly improved. This shows that the present invention combines olive leaf extract solution and alfalfa extract solution, which has a synergistic effect on increasing the fluffiness of hair.

[0088] The formulations of Comparative Examples 3 and 4 were the same as those of Comparative Examples 1 and 2, respectively, but their concentrations were increased by 5 times. However, the results showed that even with a 5-fold increase in concentration, the average change rate of fluffiness was only slightly improved and was still much smaller than that of Example 1. This further illustrates that the present invention combines olive leaf extract solution and alfalfa extract solution, which has a synergistic effect on increasing the fluffiness of the composition for hair strands. Both components are indispensable.

[0089] Chicken embryo chorionic allantoic membrane vascular test

[0090] 1. Experimental Objective and Principle

[0091] The chorioallantoic membrane (CAM) test is an early and widely used in vitro method for assessing eye irritation. The CAM is a respiratory membrane surrounding the chicken embryo. This test utilizes the intact, clear, and transparent vascular system of the mid-stage chorioallantoic membrane in hatched chicken embryos. A certain amount of the test substance is directly exposed to the CAM, and after a period of time, changes in CAM toxicity indicators (such as hemorrhage, coagulation, and vascularization) are observed. These indicators reflect changes in the morphology, color, and permeability of blood vessels and vascular networks, as well as phenomena such as CAM protein denaturation and the degree of damage. These indicators are then combined to obtain a score used to assess the eye irritation of the test substance.

[0092] The purpose of this study is to test the ability of the test substance to cause toxic changes in the chorioallantoic membrane of chicken embryos and to evaluate the elements and processes of the potential eye irritation of the substance being evaluated.

[0093] 2. Test Methods

[0094] (1) Experimental operation steps

[0095] Candling is performed on 9-day-old chicken embryos, marking the location of the air cell on the eggshell surface. Using dental serrated tweezers, the marked portion of the eggshell is peeled away to expose the white membrane, handling it carefully to avoid damaging its integrity. A few mL of 0.9% sodium chloride solution is added with a pipette to moisten the membrane; the next step can then be performed immediately.

[0096] In this test, 6 embryos were selected for each group. The polytetrafluoroethylene resin ring was placed on the chorioallantoic membrane of the chicken embryo and photographed. The composition of Example 1 was diluted with pure water to a sample concentration of 2% aqueous solution and then added to the polytetrafluoroethylene resin ring. The time of sample addition was recorded. The air cell was covered with moistened plastic wrap and the chicken embryos were transferred to a constant temperature and humidity chamber for culture. The degree of change of each toxic effect was observed and photographed.

[0097] (2) Observation of results

[0098] Observe and record bleeding, coagulation, and vascularization findings, and score them according to their severity using the following evaluation criteria:

[0099] ① No reaction was observed, CAM was normal, and there was no response to vascular effects; in this case, the score was 0.

[0100] ② No blood flow in the blood vessels, the blood vessels are clear, and the vascular effect is ghosting vessels. The score is 1 in this case.

[0101] ③ Congestion, or increased blood flow in CAM small vessels, with vascular effects resulting in capillary damage, at which point the score is 2;

[0102] ④ There are 1-10 countable tiny bleeding points within the ring, and the vascular effect is very slight bleeding. The score is 3.

[0103] ⑤ There are more than 10 countable small bleeding points in the ring, or the small bleeding points are uncountable and cover less than 1 / 8 of the area in the ring. The vascular effect is slight bleeding, and the score is 4.

[0104] ⑥ If the area covered by the bleeding points within the ring is 1 / 8-1 / 4, or if there are no bleeding points within the ring but the area covered by the erythema is less than 1 / 4, the vascular effect is very mild bleeding, and the score is 5.

[0105] ⑦ If the area covered by the bleeding points within the ring is 1 / 4 to 1 / 2, or if there are no bleeding points within the ring but the area covered by the erythema is 1 / 4 to 1 / 2, and the vascular effect is mild bleeding, the score is 6.

[0106] ⑧ Numerous bleeding points or small-area bleeding within the ring, covering 1 / 2-3 / 4 of the ring, indicate moderate vascular effect and a score of 7.

[0107] ⑨ If the area of ​​bleeding points within the ring is greater than 3 / 4, scab formation is possible, and the vascular effect indicates severe bleeding, the score is 8.

[0108] NC value: The average of the mathematical sums of the valid scores; when 0 < NC ≤ 2, it is a non-invasive stimulus, and there is no bleeding damage to the capillaries; when 2 < NC ≤ 3, it is a mild stimulus, which is a mild invasive stimulus, and there is mild bleeding damage to the capillaries; when 3 < NC ≤ 5, it is a moderate stimulus, which is a relatively severe invasive stimulus, and there is relatively severe bleeding damage to the capillaries, which may be irreversible; when NC > 5, it is a severe stimulus, which is an extremely severe invasive stimulus, and there is extensive bleeding in the capillaries, with a large amount of bleeding, which is irreversible.

[0109] (3) Test results

[0110] The NC value of the oil-controlling and fluffy composition of Example 1 of this invention was tested to be 2, indicating that the sample is safe and non-irritating. (Reference) Figure 19 , Figure 20 The image shows a comparison of the chicken embryo's state before and after the oil-controlling and fluffy composition of Example 1 was added to the chicken embryo. Figure 19 This is an observation image (0 min) of chicken embryos without the addition of the oil-controlling and fluffy composition of Example 1. Figure 20 This is an observation image (3 min) of chicken embryos after the oil-controlling and fluffy composition of Example 1 was added.

[0111] 5α-Reductase Inhibition Rate Test

[0112] 1. Experimental Grouping

[0113] Positive control: Finasteride;

[0114] Negative control: PBS buffer (pH 5.5);

[0115] Sample group: Oil-controlling and fluffy compositions of Examples 1-5 and Comparative Examples 1-2; the formulation of Comparative Example 3 is the same as that of Comparative Example 1, and the concentration during testing is 5 times that of Comparative Example 1; the formulation of Comparative Example 4 is the same as that of Comparative Example 2, and the concentration during testing is 5 times that of Comparative Example 2.

[0116] Reagents: testosterone, reduced coenzyme II tetrasodium salt, PBS buffer (pH 5.5), methanol, finasteride.

[0117] 2. Test Procedure

[0118] Three groups were set up: a sample group, a positive control group, and a negative control group.

[0119] Add 250 μL PBS buffer (pH 5.5), 100 μL sample solution / finasteride solution / PBS buffer, 500 μL enzyme extraction solution (diluted to the optimal reaction concentration), 50 μL testosterone, and 100 μL NADPH. Incubate the reaction tube at 37 °C. Take samples at 0 min and 30 min respectively, add methanol to stop the reaction, vortex for 1 min, centrifuge at 10000 rpm for 10 min, collect the supernatant and filter it through a 0.22 μm microporous membrane. Analyze by HPLC.

[0120] Each group was analyzed by HPLC under the following conditions: C18 (250 mm × 4.6 mm × 5 μm) column, column temperature 40 ℃, mobile phase methanol:water = 70:30 (v / v), flow rate 1 mL / min, diode array detector, detection wavelength 242 nm.

[0121] 3. Result Calculation

[0122] The testosterone content in the reaction solution was determined under the above chromatographic conditions. The strength of the inhibitory activity was characterized by the inhibition rate, as shown in the following formula:

[0123] .

[0124] The test results are shown in Table 6.

[0125] Table 6. Results of 5α-reductase inhibition rate test

[0126] 5α-Reductase Inhibition Rate / % Example 1 64.38 Example 2 60.71 Example 3 63.52 Example 4 59.68 Example 5 63.95 Comparative Example 1 22.38 Comparative Example 2 26.43 Comparative Example 3 23.19 Comparative Example 4 29.26 Positive control 63.62

[0127] As can be seen from the data in Table 6, Examples 1-5 all exhibited extremely high 5α-reductase inhibition rates, ranging from 59.68% to 64.38%, similar to the positive control group. This indicates that the oil-controlling and fluffy compositions obtained by combining olive leaf extract solution and alfalfa extract solution in a specific ratio according to the present invention have excellent oil-controlling effects. The concentrations of Comparative Examples 1 and 2 were consistent with those of Example 1, but the composition of Comparative Example 1 contained only olive leaf extract solution and lacked alfalfa extract solution, while the composition of Comparative Example 2 contained only alfalfa extract solution and lacked... Without the olive leaf extract solution, the 5α-reductase inhibition rate of Comparative Example 1 was only 22.38%, and that of Comparative Example 2 was only 26.43%, far lower than the 64.38% of Example 1. Example 1 combined the two components and added only a small amount of olive leaf extract solution to the alfalfa extract solution, resulting in a significant increase in the 5α-reductase inhibition rate. This demonstrates that the present invention, by combining olive leaf extract solution and alfalfa extract solution, has a synergistic effect in increasing the 5α-reductase inhibition rate of the composition and improving the oil control effect.

[0128] The formulations of Comparative Examples 3 and 4 were the same as those of Comparative Examples 1 and 2, respectively, but their concentrations were increased by 5 times. However, the results showed that even with a 5-fold increase in concentration, the 5α-reductase inhibition rate was only slightly improved and was still much lower than that of Example 1. This further illustrates that the present invention combines olive leaf extract solution and alfalfa extract solution, which has the effect of synergistically increasing the 5α-reductase inhibition rate of the composition and improving the oil control effect.

[0129] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.
