Further, in order to verify that the skin care product of the application does not cause irritation to human skin when used in a closed state, the products of examples 1 to 4 are subjected to a 24-hour closed human skin patch test according to 2015 edition of cosmetic safety technical specification: selecting 128 volunteers with ages 18-59 and meeting the standard, and dividing into 4 groups, wherein each group comprises 25 women and 7 men, and the selected area is not more than 50mm 2 A suitable patch tester with a depth of about 1mm was used, and about 0.020 to 0.025g of the product obtained in examples 1 to 4 was added to the patch tester by a closed patch test method. The patch tester is applied to the front curved side of a subject, the test object is removed after 24 hours, skin reactions are observed after 0.5 hour, 24 hours and 48 hours respectively, and the results are recorded according to the skin reaction grading standard in cosmetic safety technical Specification 2015 (specifically, the skin reaction grading standard of the human body skin patch test skin closed patch test in chapter 2 of cosmetic safety technical Specification 2015). While volunteers set up negative controls (blank, i.e., different test area skin of the same volunteer).
The results are shown in Table 5.

Marking the position of an air chamber on the surface of a normal eggshell, stripping off eggshell parts and exposing white egg membranes; carefully remove the intima with forceps to ensure that the vascular membrane is not damaged; (2) evaluation by endpoint scoring: at least 6 chick embryos in each group are taken, the products of the examples and the comparative examples are prepared, namely, 0.3. 0.3 mL is directly dripped on the surface of the CAM, the reaction condition of the CAM is observed, after the CAM is acted for 3min, the test is gently washed by normal saline to remove the test, and 3 reactions and degrees of bleeding, coagulation and vascular thawing are observed within about 30s after washing. If the observation shows that the score of at least 1 reaction of all 6 chick embryos is above moderate (total score is not less than 12), the test should be repeated once. Endpoint Scoring (ES): score per chick embryo = sum of extent of bleeding, coagulation and vascular thawing observed per chick embryo; endpoint Score (ES) =number sum of 6 chick embryo scores.

As can be seen from table 6, in the product of the example of the present application, the components except for vitamin C have substantially no apparent irritation, whereas the product of example 4 did not show irritation or comfort in use in the test of the above-mentioned effect example 2 because the irritation of vitamin C in the product of example 4 was significantly reduced due to the effect of the peony polysaccharide mixture and the peony fermentation filtrate in the product; in contrast, the product of comparative example 4 has higher irritation of vitamin C due to the absence of the above two components, and although the component has good whitening and moisturizing effects, the negative effect of skin irritation may occur when used alone; however, in examples 5 to 6 of the polysaccharide mixture prepared from the plant polysaccharide defined by the technical scheme of the application, the irritation of vitamin C can be obviously reduced, and as can be seen from the test results of comparative examples 5 to 9, the preparation process of the spatial structure composition and the skin care product which do not completely adopt the application has the effect of reducing the irritation of vitamin C, but the irritation reduction rate is obviously inferior to that of example 4.
Subsequently, the products of example 3, example 4 and comparative example 4 were subjected to whitening evaluation tests to verify that the synergistic whitening effect of the peony polysaccharide mixture, the peony fermentation filtrate and the vitamin C is achieved under the condition that the irritation of the vitamin C in the products of examples is significantly improved: selecting 165 subjects with chloasma and dark complexion on skin of 17-50 years old, randomly dividing the subjects into 5 groups of 33 subjects, using the products of examples 3-6 and comparative example 4 on the face respectively, using the products for 1.5 g/time, 2 times/day (1 time each in the morning and evening), continuously using the products for one month, and then carrying out self-judging standard by referring to the method of effect example 2, evaluating the whitening effect of the products, wherein the results are shown in Table 7, and the comparative example 4 groups have 2 subjects to give up midway and do not include statistics.
TABLE 7
As can be seen from table 7, when the products of example 4 and comparative example 4 containing vitamin C were used, the problem of darkening of skin color caused by chloasma of the skin was improved, but the whitening effect of vitamin C in example 4 was significantly increased compared with the products of example 3 and comparative example 4 due to the synergistic effect with the peony polysaccharide mixture and peony fermentation filtrate in the product components. When the products of examples 5-6 containing the polysaccharide mixture prepared from vitamin C and other plant polysaccharide are used, the synergistic whitening effect on vitamin C is achieved, and the peony polysaccharide effect is optimal.
Further, the vitamin C transdermal penetration rate test was performed on the products of example 4 and comparative examples 4 to 9: fresh pig back skin was cut to size for use by removing hair and subcutaneous tissue. Using Franz horizontal diffusion cells (effective diffusion area 1.5 cm) 2 ) Skin permeation studies were performed. Pig back skin is fixed between two diffusion tanks, the receiving liquid is isotonic PBS (pH=7.0-7.4), the test liquid is the liquid of example 4 and comparative example 4 respectively, a transdermal test is carried out in triplicate by circulating water bath at 37 ℃, 0.5mL of sample is taken at 24h after the start of the test, the sample is filtered by a 0.22 μm filter membrane and is used as a detection sample, and the content of vitamin C is detected by liquid chromatography respectively, so that the cumulative transmittance of vitamin C in the sample is calculated (the same steps as those of other comparative example products are treated). As shown in table 8.
The cumulative transmittance or retention (%) of the active material is calculated by the formula:
cumulative transmittance (%) = total transmission in receiving fluid/total in test fluid diffusion cell 100%
TABLE 8
Through tests, the cumulative transmittance of the product of the example 4 is 80.8%, but the cumulative transmittance of the product of the comparative example 4 is only 45.6%, which shows that in the product of the example 4, the effect of vitamin C penetrating through the skin is obviously increased under the action of the rest components, the vitamin C can be more effectively contacted with the deep skin and has active effect, and the vitamin C in the product of the comparative example 4 is difficult to achieve similar effect; from the results of examples 5 to 6, the space composition formed by the other polysaccharide mixture also has better permeation promotion effect on the active substances, while from the results of comparative examples 5 to 9, the permeation effect is lower than that of example 4 due to the fact that the product preparation process of the application is not fully adopted.
And the application of the product in human body test further confirms the conclusion: determining characteristic peaks of a test sample by using a Raman spectrum method, determining permeation behaviors of the sample by using a Raman imaging chart, analyzing permeation conditions of the test sample in the skin at the same time points of 0.5h, 2h, 4h and the like of a subject by using a Raman image, comparing the concentration of a standard sample of the test sample with the drawing of a Raman spectrum intensity curve, and calculating the permeation result of the sample on the skin of the subject.
The testing process comprises the following steps:
cleaning skin of a test area by using clear water after visiting, standing in a constant temperature and humidity room for 30 minutes after cleaning, carrying out product use on the test subjects taking part in the test according to test requirements after 30 minutes (taking three test areas of 1X 1 square centimeter at the front end of the arm and the forearm of each test subject, applying 5mg of sample to each test area of 1X 1 square centimeter, starting timing after clockwise uniform-speed smearing for 5 circles, calculating permeation time), and carrying out human body in-vivo Raman test (LabRAM Odyssey high-speed high-resolution microscopic confocal Raman spectrometer, 800 mm focal length, 0.35 cm) by using samples to be tested for 0.5h, 1h, 2h and 4h -1 Resolution (HORIBA)), test time is 3-5min, and raman spectral imaging data are processed and analyzed to show the distribution of the substance in human skin. Human raman test three 1 x 1 square centimeter areas inside the forearm were selected for three average tests per area to eliminate biological individual differences with the average.
The results are shown in fig. 3, fig. 4 and table 9.
TABLE 9
Similar to animal skin test, the component collocation of the product of example 4 can effectively improve the permeation effect of vitamin C contained in the product in the human skin test process, and can reach 55.67% high permeability after 4 hours.
Effect example 4
In order to verify the soothing efficacy of the product of the application, a zebra fish embryo in vivo experiment is used for testing: and (3) testing by using a model of neutrophil aggregation caused by copper sulfate-induced nerve dome cell injury in the embryonic side line region of the zebra fish. 24 fish embryos are exposed to 0.16mg/L copper sulfate pentahydrate and 5g/L sample solution of example 3, a model control group and a positive control group are simultaneously arranged, the fish embryos are fixed and sudan black stained after 40 minutes of exposure, the number of neutrophils in a lateral line area is counted and statistical analysis is carried out, and the results are shown in table 10 and fig. 5-7. From Table 10, it can be seen that the product of the application can cause the aggregation of the neutrophils in the zebra fish embryo due to the combined action of the peony polysaccharide mixture and the peony fermentation filtrate, i.e. has a relieving effect on organisms.
Table 10
Effect example 5
To verify the skin barrier effect of the skin care products containing the spatial structured composition of the present application, human body use tests were performed on the products of example 3 and comparative example 3: 10 skin-sensitive volunteers were screened, faces were selected as test sites, the test period was 14 days, and the volunteer face condition was observed and evaluated 1 day before and 14 days after the use of the samples. The test was preceded by a 1 week washout period during which the subjects used basic moisturizing water and moisturizing milk without any actives, no other products were used during the test, and subjects used example 3 (left face) and comparative example 3 (right face) half-face 14 consecutive days, respectively, with samples applied on the face after washing the face before sleeping each morning and evening, at about 0.2 g/time. The evaluation mode is that professional facial evaluation specialists evaluate the skin sensitivity condition of the faces of volunteers in 1-10 points, and the sensitivity degree change trend of the facial skin is evaluated according to the score before and after the test. The results are shown in Table 11. As can be seen from Table 11, the sensitivity of 10 volunteers to facial skin is reduced after two weeks of use, indicating that the product can establish a skin barrier on the skin surface to improve skin sensitivity, whereas the product of comparative example 3 has no similar effect, and even the sensitivity of 3 volunteers is increased after use, indicating that the components exerting the skin barrier effect in the product of the present application are peony polysaccharide mixture and peony fermentation filtrate.
