Embodiment 1-4
[0033] An aqueous solution containing a panthenol composition, the specific components are as follows in Table 1, and the unit is parts by weight.
[0034] Table 1
[0035]
[0036] The preparation method is as follows: mix all the ingredients, and get the product.
[0037] Panthenol stability test: use a conductivity tester to measure the conductivity of the panthenol composition in the initial state, measure the content of panthenol by HPLC, and test the conductivity and content every other month. The test cycle is 8 months. The panthenol content obtained by the test is as follows in Table 2 and figure 1 (where ①, ②, ③, and ④ represent Example 1, Example 2, Example 3, and Example 4, respectively), and the electrical conductivity is shown in Table 3 below. Wherein the panthenol content in Table 2 is the percentage content of the measured panthenol weight in the added amount (5 parts by weight).
[0038] Table 2
[0039] Example 1 Example 2 Example 3 ...
Embodiment 5-7
[0044] A moisturizing essence, the specific components are as follows in Table 4.
[0045] Table 4
[0046]
[0047]
[0048] After blind testing and sensory evaluation, the moisturizing essence obtained in Example 6 had better skin feel.
[0049] Water retention test: select 5 volunteers, use the skin water loss (TEWL) test probe to test the transdermal water loss TEWL (marked as T1) of the face before using the product, and then each volunteer Use 1 mL of the moisturizing essence of Example 6 once in the morning and evening, and test the transdermal water loss TEWL on the face at 48h, 7 days, 14 days, 21 days, and 28 days, and test 5 times for each volunteer in each time period , the results are averaged, see Table 5 and figure 2 .
[0050] table 5
[0051]
[0052] from Table 5 and figure 2 The results show that the moisturizing essence in this application has a good effect of retaining water and locking water.
