[Test Example 1] Measurement of sebum oil absorption capacity

When the cosmetic of the present invention is applied to the skin, high oil-absorbing powders such as silicone resin powder and silicone elastomer powder are applied in a state containing oil. Therefore, the sebum oil absorption capacity will decrease immediately after application, but after a period of time after application , The volatile components are vaporized and released, so the sebum oil absorption capacity can be restored. In order to confirm this characteristic, 5g of the compositions of Examples 1 to 5 and Comparative Example 1 were put into a beaker, and after 30 minutes at 50°C, the caprylic acid/capric acid glycerin set as artificial sebum were treated as follows. Triester (manufactured by InterMed, product name Imex MCT 60/40) was moistened and the oil absorption was measured.

In 5g of the compositions of Examples 1 to 5 and Comparative Example 1, caprylic/capric triglyceride (CAPRYLIC/CAPRIC TRIGLYCERIDE) was slowly dropped, and the weight was measured, and the sample absorbed caprylic/capric triglyceride. Continue to repeat the above operations during the acid triglyceride process. When the absorption of caprylic acid/capric acid triglyceride is not possible, record the absorbed amount of each sample, and calculate the sebum oil absorption rate according to the following formula 1.

[Formula 1] Sebum oil absorption rate (%) = the final absorption amount of caprylic/capric triglyceride (CAPRYLIC/CAPRIC TRIGLYCERIDE) of the sample (unit g)/the initial weight of the sample (5g) × 100 (%)
