Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of cosmetics, and particularly relates to an oil control composition containing tea extract as well as products and applications thereof. BACKGROUND

[0002] Skin oiliness is due to dryness and lack of water in human skin, leading to skin damage. The human self-repair and protection system will secrete oil to protect the skin. The condition of skin oiliness is from small to large. At the beginning, the oiliness may be slightly more due to the vigorous secretion of sebaceous glands. Later, the capillaries are blocked and comedones come out one by one. If not careful, the skin will be infected by bacteria and start to inflame. Thus, the comedones become acne. If not properly cared for, the skin scars will become more and more. Therefore, to fundamentally solve the problem of oiliness, it is necessary to control the skin oiliness and pay attention to the moisturizing of the skin, so as to fundamentally improve and protect the damaged skin. Regardless of neutral skin, oily skin or mixed skin, the face will be oily. Generally speaking, the oiliness of the face is a signal of skin moisturizing. We must inject enough water into the skin in time to maintain the balance of water and oil. On the other hand, it is because the facial sebaceous glands are overactive and secrete a large amount of oil, so that the skin is greasy. Therefore, it is necessary to choose suitable oil control cosmetics to control the skin oiliness and clean the skin.

[0003] Proper use of cleaning products can help us remove things that cannot be washed off the skin surface, avoid too much "inflammatory factors" on the skin, and avoid imbalance of the skin surface flora. Traditional oil control facial cleanser adds surfactants, foaming agents, soap bases and other ingredients with extremely strong alkalinity in order to improve the cleaning power and oil removal ability. However, the skin of human body is weakly acidic. Long-term use will irritate the skin, and more seriously, the skin sebum film will be damaged. Once the sebum film is lost, the skin is easily damaged by the outside world. In the prior art, plant or traditional Chinese medicine extracts are used in combination with chemical sources of auxiliary agents or antagonists. However, the use of chemical auxiliary agents will irritate the skin and cause certain impact on the skin, which reduces the effect of plant or traditional Chinese medicine extracts. In the prior art, multiple pure plant or traditional Chinese medicine extracts are used in combination. However, due to the complex preparation process of the extracts, it is difficult to uniformly adjust the effects of multiple components. Moreover, the extracts are easy to block the skin pores, and the oil control effect is not very significant, which seriously limits the development of natural source oil control products. Therefore, it is urgent to develop and research more natural oil control products. The components are mild and harmless to human body, which can be used for a long time. Moreover, the products have high oil absorption and decontamination ability, so as to avoid the adverse symptoms caused by the blockage of skin pores. SUMMARY

[0004] In order to solve the above problems existing in the prior art, the present application provides an oil control composition containing tea extract and products and applications thereof, the composition researched by the present application adopts natural plant active ingredients, is harmless to human body, can be used with confidence, and can effectively improve the oil absorption and stain removal capacity, thereby avoiding adverse symptoms caused by clogged skin pores.

[0077] Test Example 2 Long-term oil control effect

[0078] Forty-five healthy adult volunteers with oily skin and no skin diseases, aged 25-35 years, were selected and randomly divided into 9 groups, 5 people in each group. In a constant temperature and humidity environment, the testers' faces were cleaned and dried using a cleansing milk. Three areas on the forehead were selected to measure the initial value of skin oil content (μg / cm 2 ). The area without applying any sample was taken as the blank group, the area uniformly applying (2.0±0.5) / g 5% concentration sample was taken as the experimental group, and the area using only pure water was taken as the pure water group in the experimental group. The skin oil content at different times was measured using a Cuotometer MPA580 oil test probe Sebumeter made by CK Company in Germany at 1, 2, 4, 6, 8 and 12 h after the test started. The average value was taken for statistics, and the oil reduction rate was calculated by the following formula.

[0079]

[0080] The statistical results of the oil content at different times are shown in Table 2 below, and the oil reduction rate calculated according to Table 2 is shown in Table 3. The oil content on the skin surface of the subjects using pure water is equivalent to that of the blank group without applying any sample, and the oil content on the skin surface of the subjects using the samples of Examples 1-4 and Comparative Examples 1-4 is significantly reduced, among which the effect of the samples of Examples 1-4 is obvious. Examples 1-4 perform well in long-term oil control effect, and can maintain an oil reduction rate of more than 35% after 12 h. The comparison results with Comparative Examples 1-4 show that the addition of tea extract not only reduces the secretion of skin surface oil well, but also has a certain long-term oil control effect, indicating that the composition provided by Examples 1-4 has a long-term oil control effect.

[0086] Test Example 3 Real-time fluorescence RT-PCR detection of IDH gene mRNA expression level

[0087] An equal amount of HepG2 cells preserved in the laboratory (purchased from the Shanghai Cell Bank of the Chinese Academy of Sciences, SCSP-510) was inoculated in a 6-well plate, and 2 mL of the oil control cosmetic mixture of Examples 1 to 4 and Comparative Examples 1 to 4 at the same concentration was mixed with 1640 culture medium containing 10% fetal bovine serum, and then co-cultured with HepaRG cells. After 24 h, total RNA of the cells was extracted by using a TRIZOL reagent. The cells were lysed by using a TRIZOL reagent, 500 μL of chloroform was added to the cell lysate, and centrifugation was performed at 12000 rpm for 10 min. The supernatant containing RNA was collected, precipitated with an equal volume of isopropanol, and incubated for 30 min. The RNA precipitate was centrifuged at 12000 rpm for 10 min, and the nucleic acid was washed with 70% ethanol. The pellet was air-dried and dissolved in 20 μL of sterile double-distilled water, and the amount of RNA was quantified by using a micro UV-visible spectrophotometer. The RNA was converted into cDNA by using a cDNA conversion kit, and used for quantitative polymerase chain reaction. The mRNA expression level of the IDH gene expressed by the cells was detected by using a quantitative polymerase chain reaction technique. In the blank group, PBS was used instead of the same amount of solution.

[0088] The detection results are shown in Table 3, which show that the oil control cosmetic mixture prepared by Examples 1 to 4 can significantly down-regulate the mRNA level of IDH, and the down-regulation effect is significantly better than that of Comparative Examples 1 to 4. Figure 1

[0089] Test Example 4 Elisa analysis of IDH expression level

After 24 h, the cells were collected, and PBS was used instead of the same amount of solution in the blank group. The expression amount of IDH in different groups was detected by using an ELISA method, and the experimental results were analyzed by using data processing software.

[0091] The results are shown in Table 3, which show that the oil control cosmetic mixture prepared by Examples 1 to 4 can significantly down-regulate the mRNA level of IDH, and the down-regulation effect is significantly better than that of Comparative Examples 1 to 4. Figure 2 ​As shown in Table 4, the results show that the oil control cosmetic mixture of Examples 1-4 can effectively reduce the expression level of IDH of cells, and reducing the expression of IDH can limit the tricarboxylic acid cycle (TCA), thereby reducing the generation and content of testosterone, so as to achieve the effect of regulating skin oil secretion. The effect of the example of adding both vitagen and aesculetin is more significant.
