With the aging, the number of fibroblasts in the human body gradually decreases, so that the secreted collagen and elastin are gradually reduced and broken due to oxidation, the dermis layer begins to be thinned, the skin elasticity becomes poor, and wrinkles also begin to be generated gradually. When collagen of the dermis layer is oxidized and broken, supporting effect on the epidermis is reduced, thus causing heterogeneous collapse, thereby wrinkling. The human body has an enzyme called SOD, which is a substance for removing free radical garbage in the human body. With the increase of age, SOD activity gradually weakens, and in-vivo garbage is difficult to remove, so that garbage generated by free radicals is a toxic substance and is a harmful substance causing human body aging. The cosmetics containing free radical removal and antioxidation are used for nursing, so that the occurrence of skin wrinkles can be delayed to a certain extent, and the skin can keep elasticity and fineness; however, the skin is damaged due to environmental factors, so that the absorption of the skin to the effective components is reduced, and the anti-wrinkle effect is low.

Table 2 transdermal performance test

/>

As shown in Table 2, the transdermal drug delivery ability of the examples was good. Comparing comparative examples 1 to 3 with example 1, it is apparent that the three of hydroxypropyl tetrahydropyran triol, gentian extract and tetrandra root extract produce synergistic effect, so that better transdermal administration ability is obtained. While comparative examples 2 and 4 show that acetyl hexapeptide-8 forms a synergistic effect with tetrandra root extract, the intradermal retention is lower than that of comparative examples and the rest of comparative examples, i.e. the water locking efficacy is reduced.

And (3) moisture preservation effect test: moisture content was measured using a moisture tester Corneometer (CM 825, C+K, germany). The unit a.c.u. used for its measurement; the moisture loss rate was measured by using a skin moisture loss (TEWL) tester tewatter (TM 300, c+k company, germany), and the more intact the skin protective layer was, the higher the moisture content was, and the lower the skin moisture loss TEWL value was. Measurement environment: testing ambient temperature: 22+ -3deg.C, humidity: 50.+ -. 5%. A total of 45 testers (age 20-40 years) were selected and divided into 6 groups (average age 28.+ -. 2 years) using the compositions prepared in examples 1-2 and comparative examples 1-4, respectively. The initial values were measured before use, and after one month, the results were measured, and the change rate was observed, as shown in table 3.

TABLE 3 moisturizing Performance test results

The average moisture content of the skin after 30d continuous use is the result of direct test without using the product after 30d continuous use. As is clear from Table 3, the compositions prepared in the examples have excellent continuous moisturizing properties, and show a significant improvement in the moisture content of the skin after continuous use. From comparison of the rates of change of comparative examples 1-3 and examples, it can be seen from the combination of Table 2 that the transdermal delivery ability of the compositions significantly affected the moisturizing properties, i.e., the synergistic effect of hydroxypropyl tetrahydropyran triol, gentian extract and tetrandra root extract; in contrast, when comparing the rates of change of comparative example 2, comparative example 4 and examples, it can be seen in combination with Table 2 that acetyl hexapeptide-8 also forms a synergistic effect with the tetrandra root extract, which together improves the water locking properties of the composition.

Anti-aging and anti-wrinkle test

42 volunteers (age group is 30-50 years old) are selected and divided into 7 groups (average age is 40+/-2), examples 1-3 and comparative examples 1-4 are respectively used, the use parts are faces, the test parts are cheeks and canthus on two sides, the use is carried out 2 times per day, and the use is carried out after face cleaning; the average roughness of skin and the average depth of wrinkles were measured 1 day before the cosmetic was applied, 30 days after the application, using a MicroSkinII multi-functional dermoscope image analysis system to calculate the average value, see table 4. As can be seen from the change rates of Table 4, the anti-wrinkle effects were prominent and the rough skin and skin wrinkle depth values were significantly improved using examples 1 to 3 of the present invention, as compared with comparative examples 1 to 4.

TABLE 4 anti-wrinkle Performance test results

As shown in Table 4, the transdermal drug delivery ability of the examples was good. Comparing comparative examples 1 to 3 with example 1, it is apparent that the three of hydroxypropyl tetrahydropyran triol, gentian extract and tetrandra root extract produce synergistic effect, so that better transdermal administration ability is obtained. While comparative examples 2 and 4 show that acetyl hexapeptide-8 forms a synergistic effect with tetrandra root extract, the intradermal retention is lower than that of comparative examples and the rest of comparative examples, i.e. the water locking efficacy is reduced.

Antioxidant Capacity test

1. Principle of testing

Free radical overproduction is a major cause of natural aging and photoaging of the skin. Therefore, the free radical is removed to delay skin aging and reduce wrinkles. 1, 1-diphenyl-2-trinitrophenylhydrazine (DPPH) is a stable long-life free radical, and when a free radical scavenger exists, the light absorption of the DPPH ethanol solution is weakened due to the single electron pairing with the free radical scavenger. The extent of discoloration of the DPPH ethanol solution is linearly related to the number of electrons it receives, and thus the ability of the test sample to scavenge free radicals, i.e., the magnitude of antioxidant activity, can be evaluated.

2. Test article:

test sample originals (examples 1-3 and comparative examples 1-4): the test concentration was 200mg/mL

3. The testing method comprises the following steps:

the test sample was pretreated to prepare a solution. Adding the free radical DPPH, preparing a multi-tube sample, shaking uniformly, standing for a period of time at room temperature, testing and measuring the light absorption value at 517nm by an upper machine, calculating the capability of the sample to remove the free radical and calculating the statistical difference P value, and the result is shown in Table 5.

TABLE 5 radical scavenging results

Sample of	Radical scavenging rate%	P value
			Example 1	62.65	＜0.05
Example 2	61.95	＜0.05
			Example 3	62.45	＜0.05
Comparative example 1	30.25	＜0.05
			Comparative example 2	28.94	＜0.05
Comparative example 3	29.34	＜0.05
			Comparative example 4	28.53	＜0.05
Blank control	0	＜0.05

P < 0.05 indicates statistical significance, and as can be seen from Table 5, the compositions provided in the examples have good free radical scavenging effect; and the data of comparative examples and comparative examples 1-3 show that the three extracts of hydroxypropyl tetrahydropyran triol, gentian extract and tetrandra root extract produce synergistic effect, so that the transdermal administration capacity is better, and the components such as antioxidant and the like capable of removing free radicals penetrate through the epidermis layer to reach the dermis layer, so that the better free radical scavenging effect is obtained. While comparative examples 2 and 4 show that acetyl hexapeptide-8 forms a synergistic effect with tetrandra root extract, and that the composition of comparative example 4 has transdermal administration capability, but has higher loss rate, resulting in poor free radical scavenging effect.

Comfort evaluation in use

The subjects in the anti-aging test were evaluated for the skin feel of the skin cream used and the skin cream used in examples 1 to 3 and comparative examples 1 to 6, the evaluation was made as 10-minute full scale, the average was taken, the higher the score was, the better the corresponding effect was, and the evaluation results are shown in Table 6.

Table 6 results of comfort evaluation

Sample of	Skin feel and Effect evaluation	Score of
			Example 1	Smooth, soft, moist but not greasy, easy to absorb, excellent in moisturizing effect and strong in comfort	9.98
Example 2	Smooth, soft, moist but not greasy, easy to absorb, excellent in moisturizing effect and strong in comfort	9.96
			Example 3	Smooth, soft, moist but not greasy, easy to absorb, excellent in moisturizing effect and strong in comfort	9.95
Comparative example 1	Smooth, soft, moist but not greasy, easy to absorb, poor in moisturizing effect and strong in comfort	7.55
			Comparative example 2	Smooth, soft, moist but not greasy, poor in absorption effect, poor in moisturizing effect and strong in comfort	7.56
Comparative example 3	Smooth, soft, moist but not greasy, easy to absorb, poor in moisturizing effect and strong in comfort	7.53
			Comparative example 4	Smooth, soft, moist but not greasy, poor in absorption effect, poor in moisturizing effect and strong in comfort	7.61
Comparative example 5	Easy absorption, excellent moisturizing effect and poor comfort	6.53
			Comparative example 6	Smooth, soft and moist, easy to absorb, excellent in moisturizing effect and poor in comfort	4.52

As is clear from Table 6, the evaluation of the use of examples 1 to 3 was high, and the comfort was poor in comparative example 6 in which the sodium acrylate/sodium acryloyldimethyl taurate copolymer was not added. By combining comparative example 5, it is demonstrated that the sodium acrylate/sodium acryloyldimethyl taurate copolymer and the emollient produce a synergistic effect, which not only improves the emollient function of the emollient, but also improves the comfort of the product.
