TABLE 1
TABLE 2
Comparative examples 1 to 4
The moisturizing eye creams of comparative examples 1 to 4 differ from example 1 only in the formulation, and the formulation of the moisturizing eye creams in each comparative example is shown in table 3.
TABLE 3 Table 3
Effect detection
1. Moisture effect test
To verify the efficacy of the eye cream of the present invention, the samples obtained in examples 1 to 4 and comparative examples 1 to 4 were subjected to a moisturizing effect test.
The testing method comprises the following steps:
the group of 25-45 years old volunteers was selected, and the volunteers were patients without serious systemic disease, immunodeficiency or autoimmune disease, patients without active allergic disease, patients without serious allergic history to cosmetics, patients without hormone drugs and immunosuppressants in the past month, and subjects without other clinical testers. Volunteers were divided into 8 groups of 10 persons each, with no significant differences between the groups. Skin around eyes is selected as a test part, the skin is tested once before the test (i.e. the product of the invention and the comparative example is not used), the tested product is used after the face is cleaned in the morning and evening every day, the time of applying the sample is counted, and the moisture content of the horny layer and the skin glossiness of the test area are measured in 28 days. The test products were the samples of examples 1-4 and comparative examples 1-4, respectively. The stratum corneum moisture content and Skin gloss were measured using a Skin moisture test probe Cornometer CM825 and a Skin gloss test probe Skin-Glossymeter GL200 (Courage+Khazaka, 50829Koln, germany), respectively.
Analysis of the result data:
a. calculation of moisture and gloss Change amount
The average difference between the moisture content of the stratum corneum and the skin glossiness of the tested part before and after the product is obtained by subtracting the measured value of the tested part before the use from the measured value of the tested part after the sample, and the calculation formulas are as shown in the following formulas (1) and (2).
(1)T＝(M x -M o )/10；(2)G＝(N x -N o ) 10; wherein: t is skin moisture variation; m is M x A measurement of skin moisture 28 days after use of the product; m is M o Pre-use measurements for skin moisture products; g is the skin glossiness variation; n (N) x To measure skin gloss 28 days after use of the product; n (N) o Is a measurement of skin gloss product before use.
The test results are shown in Table 4.
TABLE 4 Table 4
| Sample numbering | Average difference in skin moisture content | Average difference in skin gloss |
| Example 1 | 34.00 | 3.36 |
| Example 2 | 30.00 | 3.23 |
| Example 3 | 29.00 | 3.18 |
| Example 4 | 28.00 | 3.05 |
| Comparative example 1 | 23.00 | 2.43 |
| Comparative example 2 | 25.00 | 3.07 |
| Comparative example 3 | 24.00 | 2.17 |
| Comparative example 4 | 25.00 | 3.02 |
From the test results in Table 4, it is evident that the products obtained in examples 1-4 have a significant improvement in moisture content and gloss of the skin of the user, wherein the products obtained in examples 1-2 are improved to a higher degree than the products obtained in examples 3 and 4. From the test results of the products obtained in comparative examples 1-4, it is known that the addition amount of the components in the eye cream formula has a great influence on the moisturizing effect of the products, especially when the addition amounts of ginger root oil, ginger root extract, hyaluronic acid and plant extract mixture are insufficient, the obtained products have obvious differences in skin moisture content and glossiness improving effect after use compared with the products of examples.
2. User experience testing
To test the use experience of the eye cream of the present invention, 8 samples of examples 1 to 4 and comparative examples 1 to 4 were subjected to a user experience test, and volunteers tested for moisturizing effect were subjected to a return visit investigation, and statistics were made as to whether the volunteers were dry after use and developed a white dust phenomenon, odor evaluation, and skin comfort evaluation. Wherein the odor evaluation total score is 5 points, and the 5 scoring criteria are: the smell is coordinated and natural, and pleasant aroma is obtained; the 4 scoring criteria were: the smell is coordinated, and a certain fragrance exists; the 3 scoring criteria are: the smell is general, has a certain special smell, but is generally coordinated and not objectionable; 2 scoring criteria: has certain unpleasant smell, weaker coordination and general adaptation after habit; score 1 criteria: the dissonance and peculiar smell are obvious, objectionable and cannot be adapted. The total score was rated 5 points using skin comfort, with 5 scoring criteria: the texture is comfortable when the skin-care product is used, and the skin can absorb quickly after the skin-care product is used; the 4 scoring criteria were: the texture is good when in use, and the skin can absorb quickly after use; the 3 scoring criteria are: the texture is general when in use, and the skin absorption speed is general after use (the whole is the same as that of the commercial eye cream); the scoring criteria for 2 were: the texture is poor (not fine or smooth) when in use, or the absorption speed is slower after use; the scoring criteria for 1 were: the texture is poor when in use, and the skin absorption speed is low after use. The scores were counted and averaged, and the results are shown in Table 5.
TABLE 5
As can be seen from the table, the eye cream samples prepared in examples 1-4 were pleasant in overall smell, and were good in skin comfort after use, and did not develop a phenomenon of dry and flaking.
In combination, the samples obtained in examples 1-4 have a good use experience and excellent skin quality enhancement, with the product obtained in example 1 being the most effective.
While the foregoing is directed to the preferred embodiments of the present invention, it will be appreciated by those skilled in the art that changes and modifications may be made without departing from the principles of the invention, such changes and modifications are also intended to be within the scope of the invention.
