Description

Technical Field

[0001] The present invention belongs to the technical field of cosmetics, and in particular relates to a skin care composition having the effects of controlling oil, replenishing moisture and balancing oil and fat, and an application thereof. Background Art

[0002] With the increasing pressure of work and life, environmental pollution, seasonal changes, and aging, more and more people are experiencing the problem of oily face. Oily face is one of the skin problems faced by many people. It not only affects personal image, but also may cause a series of skin problems. In order to eliminate this problem, oil control products are increasingly attracting the attention and use of consumers.

[0003] CN118662414A discloses an oil-controlling astringent composition, cosmetics and oil-controlling astringent water. The oil-controlling astringent composition includes, by mass, 10 parts of roselle flower extract and 5-20 parts of nephrolepis extract. 10 parts of roselle flower extract and 5-20 parts of nephrolepis extract are matched with each other and synergistically enhance each other, and have good oil-controlling astringent effects, and can achieve oil-controlling astringent effects from multiple pathways. The oil-controlling astringent composition of the application uses the above substances to treat both the symptoms and the root causes through multiple pathways, regulate the state of the skin, and thus improve the oil secretion of the skin, which is more gentle and safe.

[0004] CN118743631A discloses an oil control composition and its preparation method and application. The method adds medicinal fasciculus, white willow bark, lotus root seeds, soluble zinc salt, carbon source, and nitrogen source into water, then inoculates saccharomyces cerevisiae for fermentation, and finally extracts the oil control composition by water. The invention specifically selects three traditional Chinese medicine components, compounding them with soluble zinc salts and other components to obtain a semi-solid fermentation medium, and specifically designs its process (first fermentation with saccharomyces cerevisiae and then water extraction), so that the obtained oil control composition is compared with other traditional Chinese medicine components and products obtained by other processes. The release amount of oil control components has been significantly improved, and it has a more excellent oil control effect.

[0005] At present, more and more products on the market have oil control effects, but single oil control will lead to a decrease in skin resistance and cause more skin problems. Therefore, it is very necessary to develop a product that can control oil for a long time and keep the skin healthy. Summary of the invention

Volunteers were arranged to undergo oil control efficacy tests before using the product, 14 days after using the product, and 28 days after using the product to obtain the skin oil content. The oil control efficacy test used the cuotometer MPA580 oil test probe Sebumeter manufactured by German Courage+Khazaka (German CK Company) to test the forehead area 5 times and take the average value.

[0124] The rate of change after 14 and 28 days of use of the product was calculated using the following formula:

[0125] In the formula, D0 is the basic value of skin parameters before the test area uses the product; D14 is the value of skin parameters after the test area uses the product for 14 days; D28 is the value of skin parameters after the test area uses the product for 28 days.

[0126] The test results are shown in Table 1:

[0127] Table 1

[0128]

[0129]

[0130] It can be seen from Table 1 that: From the comparison of Application Examples 1-3, it can be seen that the essence of the present invention has an excellent oil control effect and can regulate the water-oil balance of the skin with long-term use.

[0131] From the comparison between Application Example 1 and Application Examples 4-8, it can be seen that the skin care composition with the functions of oil control, moisturizing and oil balancing can better improve the oil control effect of the essence by adding plant extracts, and the type selection has a great influence on the oil control effect of the essence.

[0132] It can be seen from Application Examples 1 and 9-11 that the type of moisturizing oil selected will affect the oil control effect of the product.

[0133] From the comparison between Application Example 1 and Comparative Application Examples 1-5, it can be seen that tetrahydromethylpyrimidine carboxylic acid, madecassoside, PEG / PPG-14 / 7 dimethyl ether, mucopolysaccharide and 4D hyaluronic acid in the skin care composition with the effects of oil control, moisturizing and oil balancing of the present invention have a certain synergistic effect in the above-mentioned oil control and oil balancing effects, and the combination of the five is indispensable.

[0134] Test Example 2: Improvement of skin moisture test

[0135] The effect of improving skin moisture of the essence prepared by using Example 1-11 and Comparative Application Example 1-5 was evaluated:

[0136] 80 users with dull, yellowish and dry facial skin, aged between 20 and 45 years old, were randomly selected and divided into 16 groups, with 5 people in each group. The 16 groups of test subjects respectively tried the essences prepared in Application Examples 1-11 and Comparative Application Examples 1-5, once in the morning and once in the evening, for 28 days. During the test period, the subjects were not allowed to use other items that maintain skin moisture and skin elasticity and cosmetics that affect the results, and did not change their original eating habits during the test period.

[0137] On the 0th day and the 28th day, the skin moisture content was tested with the skin moisture tester Corneometer CM825 to evaluate the moisture content of the skin before and after. The probe was used to measure the same tested area three times and the average value was taken. The results are shown in Table 2.

[0138] Table 2

[0139]

[0140]

[0141] From the results in Table 2, it can be seen that the skin moisture content growth rate of volunteers using the essences in Application Examples 1-3 of the present invention for 28 days was above 20%, indicating that the product of the present invention has a good effect of improving skin moisture and replenishing water and moisturizing.

[0142] It can be seen from Application Examples 4-8 that the selection of plant extracts and their types have a great influence on the moisturizing effect of the essence, and the alpine edelweiss callus extract, Selaginella extract, Polygonatum odoratum extract and Dendrobium officinale stem extract have a synergistic effect in moisturizing.

[0143] From application examples 9-11, it can be seen that the synergistic combination of caprylic / capric triglyceride, isononyl isononanoate and isohexadecane can make the product's moisturizing effect more significant.

[0144] It can be seen from comparative application examples 1-5 that the five components of tetrahydromethylpyrimidine carboxylic acid, madecassoside, PEG / PPG-14 / 7 dimethyl ether, mucopolysaccharide and 4D hyaluronic acid promote each other in terms of moisturizing effect and have an unexpected synergistic effect.

[0145] Test Example 3 Consumer Sensory Effect Evaluation

[0146] The test subjects and test case 1 are the same group of volunteers.

[0147] Test method: The subjects used the essences of application examples 1-11 and comparative application examples 1-4 respectively. After cleansing the face in the morning and evening, each volunteer took an appropriate amount of essence and evenly applied it to the whole face. After 15 minutes, wash it off with clean water. Use it for 28 days. After use, the subjects evaluated the moisturizing effect, oil control effect and moisturizing effect before and after using the essence water and scored them. The 5-point system was adopted: the highest score was 5 points, 4.5-5 means very good, very satisfactory; 3.5-4.5 points are good; 2.5-3.5 points are medium and acceptable; 2.5 points or less are not good, unacceptable. The score of each group is the average of 10 people, and the results are shown in Table 3.
