Description

Technical Field

[0001] The invention belongs to the technical field of cosmetics, and in particular, relates to a composition having the effect of promoting transdermal absorption. Background Art

[0002] Transdermal absorption in cosmetics refers to the process in which the functional ingredients in cosmetics act on the skin surface or enter the epidermis or dermis, and accumulate and play a role in this part. With the development of the cosmetics industry, people have higher and higher requirements for the functions of cosmetics. Many people hope to have a cosmetic that can both inhibit bacteria and reduce inflammation and promote transdermal absorption. When cosmetics have antibacterial ingredients, these ingredients can prevent bacteria from multiplying on the skin to a certain extent, thereby reducing bacterial damage to the skin. At the same time, since the bacteria on the skin surface are suppressed, its transdermal absorption channel is also more unobstructed, making it easier for active ingredients to penetrate into the deep layers of the skin. However, most of the cosmetics currently on the market focus on the efficacy of the finished product and ignore the issue of whether the user's skin can absorb it. Therefore, it is very necessary to develop a composition for cosmetics that has the effect of promoting transdermal absorption and antibacterial effects to meet consumers' demand for high-quality cosmetics. Summary of the invention

[0030] (3) The present invention mainly uses kudzu root extract, and lithospermum root extract and centaury flower extract as supplementary ingredients, so that the prepared composition has excellent antibacterial and anti-inflammatory effects. In this system, the kudzu root extract with kudzu root isoflavone as the main active ingredient effectively inhibits the activation of NF-κB cells, thereby achieving anti-inflammatory effects; at the same time, the lithospermum root extract is supplemented, and the main active ingredients in the lithospermum root are naphthoquinone compounds such as shikonin, deoxyshikonin, acetylshikonin and isobutyrylshikonin, among which naphthoquinone derivatives such as shikonin have inhibitory effects on various fungi, and the centaury flower extract mainly contains bitter substances, alkaloids, phytosterols and phenolic acid compounds, which can effectively enhance the antibacterial and anti-inflammatory effects of the system.

[0031] (4) The present invention also adds a Centella asiatica extract containing ingredients such as asiatica glycoside, hydroxy-madecassoside, and asiatica sugar, which not only increases the antibacterial and anti-inflammatory effects of the composition but also adds anti-allergic and soothing effects, thereby enhancing the efficacy of the composition.

[0075] Test Example 1

[0076] (1) Tested bacteria: Escherichia coli ATCC 8739, Staphylococcus aureus ATCC 6538, Bacillus subtilis ATCC 55614;

[0077] (2) Culture medium: Nutrient broth medium: Take 18 g of nutrient broth solid medium, dissolve it in 1000 mL of purified water, sterilize it by high pressure at 121°C for 15 min, and set aside;

[0078] (3) Preparation of bacterial suspension: Test tubes and nutrient broth medium were sterilized at 121°C for 30 min and then used. Three sterilized test tubes were taken from a clean bench and sealed with 5 mL of nutrient broth medium silicone plugs. After the medium was cooled to below 40°C, appropriate amounts of Escherichia coli, Staphylococcus aureus, and Bacillus subtilis were taken with an inoculation loop and placed in the test tubes. The mixture was mixed and placed in a 37°C incubator for 18-24 h. The turbidity of the bacterial suspension was then adjusted with a McFarland turbidimeter to a value of 10 5 CFU / mL, reserve;

[0079] (4) Test sample: finished products of the compositions prepared in Examples 1-3 and Comparative Examples 1-9, with a concentration of 2%;

[0080] (5) Test method and judgment: Use a pipette to draw 300 μL of bacterial suspension into the solid culture medium and spread it evenly with a spreader. Use sterile tweezers to pick up the Oxford cup and place it on the culture medium with the evenly spread bacterial solution, so that the Oxford cup and the culture medium are fully in contact with each other without leaving any gaps. The Oxford cup should be placed in a moderate position. Repeat the experiment three times for each bacterial species. After adding 150 μL of sample solution to each Oxford cup, place the culture dish in an incubator, and place Escherichia coli, Staphylococcus aureus, and Bacillus subtilis in a 37°C incubator for 18-24 hours. Observe the size of the inhibition zone at 18, 21, and 24 hours, and measure the diameter of the inhibition zone with a ruler.

[0081] The results are the average of the three measurement data. The inhibition zone diameter greater than 7 mm is judged to have antibacterial effect; the inhibition zone diameter less than or equal to 7 mm is judged to have no antibacterial effect; the larger the inhibition zone diameter, the better the antibacterial effect. The test results are shown in Table 3.

[0082] Table 3

[0083]

[0084] As can be seen from Table 3, the composition prepared by the present invention has excellent effect of promoting transdermal absorption and antibacterial performance. Specifically, it can be seen from Comparative Examples 7-9 that no matter which one of Pueraria lobata extract, Lithospermum officinale extract and Flos Centifoliae extract is not added, the antibacterial effect measured is extremely poor, wherein, it is most obvious without adding Pueraria lobata extract; and from Comparative Example 4, it can be seen that if Cyperus rotundus volatile oil, Vitex rotundus volatile oil and Ledum palustris volatile oil are not added, the system lacks the component that promotes transdermal absorption effect, although there is still antibacterial effect in the end, but at the same time, the diameter of its antibacterial circle is not as large as that of Cyperus rotundus volatile oil, Vitex rotundus volatile oil and Ledum palustris volatile oil, that is, the promotion of transdermal absorption at the same time is weak and the antibacterial effect is not so good; and from Comparative Examples 1-3, it can be seen that no matter which one of Cyperus rotundus volatile oil, Vitex rotundus volatile oil and Ledum palustris volatile oil is not added, the diameter of its antibacterial circle at the same time is not as good as that of Examples 1-3.

[0085] Test Example 2

[0086] 48 volunteers aged 23-50 with healthy skin were randomly selected, regardless of gender, and randomly divided into 4 groups, 12 in each group. A 2cm×2cm square area on the inside of the left and right arms of the volunteers was used as the test area, and the test area was cleaned with clean water. After waiting for 10 minutes, a 50% capsaicin aqueous solution (about 0.01 mL) was used to stimulate the test area for 20 minutes, causing skin allergies, and then the 4 groups of volunteers were evenly smeared with 0.05 mL of the same cream with the composition prepared in Examples 1-3 and Comparative Example 10 (wherein, the amount of the composition added was 4% of the total mass of the cream, and except for the different compositions, the cream matrix was the same), and 60 minutes after applying the cream, the skin erythema value E was measured by a skin colorimeter to reflect the changes in the skin redness and swelling phenomenon, and the average value of each group of data was taken as the final result, thereby feeding back the sensitivity-relieving performance of the test sample, and the results are shown in Table 4.

[0089] It can be seen from Table 4 that the composition prepared by the present invention has an excellent soothing effect. In detail, by comparing the erythema value E data of Comparative Example 10 and Examples 1-3, it can be seen that the soothing performance of the Centella asiatica extract component is excellent.
