Description

TECHNICAL FIELD

[0001] The present application belongs to the field of daily chemicals, and particularly relates to a skin care composition containing honeysuckle extract and application thereof. BACKGROUND

[0002] With the development of social diversity, people's definition of beautiful skin color is also more and more diversified, among which the bronze skin color is favored by more and more people. People can change their skin color to bronze through sunbathing, using artificial sunlamps, applying exogenous coloring products, etc. This way of making skin color present a dark tone through natural or artificial external means is called tanning.

[0003] Tanning plays an important role in the fields of fitness, fashion, etc. Bronze skin not only can enhance the visual contrast of muscle contours, highlight the body line, and improve the body performance, but also can convey a healthy, sunny and energetic personal image to people. In the tanning process, the use of tanning agents can help improve the tanning effect, make the skin color more uniform and beautiful, and also can safely and quickly shorten the tanning period and save people's energy. The core component of the current ordinary tanning agent is dihydroxyacetone, which has certain irritability and can easily cause consumers to have allergic reactions such as erythema, itching, and herpes, and long-term use can easily damage the skin barrier function and have adverse effects on human health.

[0050] The preparation method of the comparative example can be obtained in the same way. If there is no added substance, it can be deleted in the corresponding preparation step.

[0051] Experimental test: the above examples and comparative examples are subjected to efficacy evaluation, subjective evaluation of subjects, and product safety test.

[0052] Test method: the instrument used is a skin color test probe Delfin SkinColorCatch.

[0053] 1. Human efficacy evaluation

[0054] (1) 90 ordinary people aged 18-65 years old are selected to use the sample together. The change rate of skin color ITA° and skin melanin index MI is calculated to verify the tanning effect of examples 1-3 and comparative example 1.

[0055] (2) Sampling points: after screening into the group, the subjects need to clean the test site with clean water, wipe dry with dry facial tissues, sit quietly in a room meeting the environmental requirements for 20 min, and cannot drink water and beverages during this period. The test site is exposed and kept relaxed. The face is selected as the test area, and the left and right faces are selected as the sample area and the control area respectively. The sample area uses the example, and the control area uses the comparative example. The initial value before sample and the value at 24 hours after sample are tested. The control area and the sample area of skin color ITA° and skin melanin index MI should have randomness, and the control area and the sample area should be randomly and uniformly present on one side of the total sample left and right sides. The sampling points of the control area and the sample area should be left-right symmetrical, and the positions of all the control areas and sample areas should be balanced in statistics.

[0056] (3) Use of sample: the subjects take an appropriate amount of product and apply it to the sample area, use a cotton swab to gently apply it to the test area, and massage it until it is completely absorbed. No other cosmetics are used on the test area during the test period.

[0057] (4) Efficacy test: the time of applying the sample is counted, and the skin color ITA° and skin melanin index MI of the sample area and the control area of the subjects are tested for 24 hours using the skin color test probe Delfin SkinColorCatch. Each area is tested in parallel for 2 times, and the average value is taken as the value of each index.

[0058] (5) The test of the same subject must be completed by the same tester using the same instrument, and the test probe should be cleaned between two measurements.

[0059] (6) Data difference analysis: difference analysis of sample area and control area after using the product, significant value p < 0.050, indicating that there is a significant difference between the sample area and the control area; p ≥ 0.050, indicating that there is no significant difference between the sample area and the control area.

[0060] (7) Change rate = [(average value after sample use-average value before sample use) / average value before sample use]*100%.

[0061] The test results are shown in Tables 2-3, and Table 2 is the test data analysis.

[0062] Table 2

[0063]

[0064]

[0065] From the test results of Examples 1-3 and Comparative Example 1, it can be seen that the skin melanin index MI of the test area of the sample of Example 1 significantly increased by 1.9% after 24 hours of use, and the skin color ITA° significantly decreased by 10.9%. The skin melanin index MI of the test area of the sample of Example 2 significantly increased by 3.1% after 24 hours of use, and the skin color ITA° significantly decreased by 23.7%. The skin melanin index MI of the test area of the sample of Example 3 significantly increased by 3.5% after 24 hours of use, and the skin color ITA° significantly decreased by 21.8%. This shows that Examples 1, 2 and 3 have a tanning effect 24 hours after use relative to Comparative Example 1.

[0066] Comparative Example 1 without the addition of honeysuckle extract does not have a tanning effect, and Examples 1-3 with the addition of honeysuckle extract have a tanning effect, indicating that the honeysuckle extract is the core effective component of the combination of the present application and has the ability to tan.

[0067] 2. Subjective evaluation of the subjects

[0068] Thirty volunteers were selected, and the thirty volunteers first used Example 1 together, then used Example 2 after testing, and so on. The face was selected as the test area, and the left and right faces were selected as the sample area and the control area, respectively. The sample area used Example 1, and the control area did not use any sample. After cleansing, the samples of Examples 1-3 and Comparative Example 1 were evenly applied to the test area of the sample area, and gently massaged until completely absorbed. The tanning effect of the test area was investigated by subjective questionnaire 24 hours after use, to evaluate the improvement effect of the skin tanning after using Examples 1, 2, 3 and Comparative Example 1.

[0069] The 1-4 point scoring standard is adopted, 1 point: not satisfied; 2 points: less satisfied; 3 points: satisfied; 4 points: very satisfied. The subjective evaluation results of the subjects are shown in Table 3.

[0070] Table 3

[0071]

[0072]

[0073] From the test results of Examples 1-3, it can be seen that the users are more satisfied with the tanning effect of the composition of the application, and the tanning effect is significant, indicating that the composition of the application has excellent tanning effect.

[0074] 3. Safety test

[0075] (1) 31 subjects were selected for testing, and a suitable patch tester with an area of not more than 50 mm 2 , and a depth of about 1 mm was selected. The test substance was diluted and added to the patch tester at 0.020-0.025 ml in a closed patch test method. The patch tester was attached to the flexor of the forearm of the subject, and after 24 hours, the test substance was removed. The skin reaction was observed at 0.5, 24, and 48 hours after removal, respectively, and the results were recorded according to the skin reaction grading standard in the "Cosmetic Safety Technology Standard 2015" (Table 4). The test results are shown in Table 5.

[0076] Table 4 is the skin reaction score grading standard.

[0077] Table 4

[0078]

[0079] Table 5
