4. Moisturizing effect

The moisturizing effect referred to in the present invention is tested with 12 subjects, and a double-blind test method is adopted. After the subjects washed their face with clean water, they were allowed to acclimate their skin for 30 minutes in a room with controlled temperature (24°C to 26°C) and humidity (50% to 60%), and then used an epidermal moisture meter (Corneometer CM825) , Courage-Khazaka electronic GmbH, Germany) was used to measure the water content of the stratum corneum on both sides of the subject’s cheeks in arbitrary capacitance units (ACU). Next, the composition of Example 2 was applied to the subject's face to form a mask with a thickness of about 0.2 mm. After eight hours, moisten the mask with water and peel off the mask. In the foregoing After the skin is domesticated, the water content of the horny layer on both sides of the subject’s cheeks is measured again. Then, the percentage increase (%) relative to the water content of the stratum corneum before applying the above composition was calculated, and the percentage increase in water content was used to express the moisturizing effect, and the same method was used to measure Example 5, Example 6, and Example 5. The results of the moisturizing effects of the compositions of Comparative Example 3 and Comparative Example 4 are shown in Table 2.

The ease of removal of makeup referred to in the present invention is to apply the mask composition of Example 2 on the arm skin of the subject. After forming the mask, apply makeup on the formed mask and uncoated skin (representing the blank group). After the process of removing the makeup, the ease of removal of the makeup was evaluated according to the residue of the makeup. Example 2 used a small amount of room temperature water to spray on the mask. After the mask was moistened, the mask was peeled off by hand and removed Makeup, while the blank group uses a lot Water to clean makeup. The specific evaluation criteria are as follows, and the results are shown in Table 3 and FIGS. 5A to 5B.

FIG. 5A shows that the makeup clothes are attached to the mask formed by the mask composition of Example 2 without blooming, and the makeup on the mask has the same makeup feel as the makeup on the skin. In addition, the makeup on the mask can be removed when the mask is moistened with a little water at room temperature. As mentioned above, since the facial mask of Example 2 has good peeling ease and can effectively isolate makeup, the makeup can be easily and completely removed while peeling off the mask. The uncoated skin is washed with water, but the makeup cannot be washed off with a lot of water. The foregoing results show that the mask formed by the mask composition of Example 2 has good makeup removal ease.

9. Whitening effect

The whitening effect test is to evaluate the whitening effect of the coated or uncoated composition of Example 8 to Example 10, and Comparative Example 6 to Comparative Example 7 with 4 subjects. After washing the subject’s arm skin with a 12% sodium lauryl ether sulfate (SLES) foam cleanser, apply 30% dihydroxyacetone on the arm skin with ^{an area of 2 cm 2} The solution was rinsed with water for 40 minutes, and then waited for 24 hours to fully brown the keratin of the skin to simulate the state of tanning. The appearance of the skin is shown in Figure 6A. Then, the skin black/red pigment probe (Mexameter MX18, Courage-Khazaka electronic GmbH, Germany) and the skin color probe (Colorimeter CL400, Courage-Khazaka electronic GmbH, Germany) were used to measure the epidermal melanin content and L value, and calculate the individual typology angle (ITA), as the skin "before processing" data.

The skin black/red pigment probe obtains the amount of light absorbed by the skin by measuring the amount of light reflected on the skin with a known amount of light of a specific wavelength, and expresses the melanin content with it. The unit is arbitrary colorimeter unit (arbitrary mexameter unit).

ITA is a skin color measurement index established based on the CIE (International Commission on Illumination) L*a*b* color space. The higher the ITA, the better the whitening effect, and the ITA can be calculated by the following formula (I): ITA (degrees) )={Arc Tangent[(L-50)/b]}×180/π (I)

The L value represents the brightness, and the value ranges from 0 (black) to 100 (white)

b value represents yellow/blue light

Then, the composition of Example 8 to Example 10 and Comparative Example 6 to Comparative Example 7 was coated on the skin of the test subject to form a facial mask, wherein the coating amount of the composition was 120 mg, and it was peeled off after 8 hours. In addition to the mask. After 5 consecutive days at a frequency of once a day, the epidermal melanin content and L value of the subjects with and without the mask were measured, and the ITA was calculated as the "after-treatment" data of the skin, and Calculate the melanin content, the L value and the rate of change of ITA to evaluate the whitening effects of the Examples and Comparative Examples. The above results are shown in Table 4, and the appearance of the treated skin is shown in Fig. 6B.

Regarding the change rate of melanin content, L value and ITA, the calculation method is shown in formula (II):

Please refer to Table 4, Figure 6A and Figure 6B, in which Table 4 is the result of the aforementioned whitening effect test, and Figure 6A is a photo of the subject's arm skin after treatment with dihydroxyacetone solution, and Figure 6B is a photo taken according to Figure 6A. A photograph of the arm skin of the test subject after coating or not coating the compositions of Example 8 to Example 10 and Comparative Example 6 to Comparative Example 7.

Table 4

From Table 4, Figure 6A and Figure 6B, it is shown that Example 8 is compared to the composition of Comparative Example 6 and Comparative Example 7 without adding PEG/PPG/polybutyl glycol-8/5/3 glycerol (B) , Example 9 and Example 10 added PEG/PPG/polybutyl glycol-8/5/3 glycerin (B) composition formed by the mask has a better whitening effect on the arm skin of the test subject, among them The whitening effect of the usage amount of 3% by weight of Example 8 is better. This shows that PEG/PPG/polybutylene glycol-8/5/3 glycerin (B) can enhance tranexamic acid (G1-2) and retinol (G2-1) in the composition of the retention mask of the present invention The whitening effect.

In summary, the composition of the resident facial mask of the present invention is formed by controlling the amount of film-forming agent (A) and the weight ratio of film-forming agent (A) to moisturizing penetrant (B). After being used for a preset period of time, the resident mask can indeed provide good comfort, adhesion, ease of peeling, and moisturizing effect. It can also effectively isolate makeup and resist adhesion of pollutants. Furthermore, due to the good peeling ease, peeling off the mask will not cause skin keratinous damage, and after using a little room temperature water to moisten the mask, the mask can be peeled off and the makeup on the mask can be removed at the same time. In addition, the composition of the resident facial mask of the present invention can enhance the transdermal penetration of the active additive (G) through the moisturizing penetrant (B), thereby helping to enhance the efficacy of the active additive (G).

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention. Anyone with ordinary knowledge in the technical field of the present invention can make various changes and modifications without departing from the spirit and scope of the present invention. Retouching, therefore, the scope of protection of the present invention shall be subject to the scope of the attached patent application.
