[Test Example 1] Sebum absorption ability measurement

When the cosmetic according to the present invention is applied to the skin, high oil absorption powder such as silicone resin powder or silicone elastomer powder is applied in a state containing oil, so the sebum absorption ability is lowered immediately after application. As the minutes are vaporized and released, sebum absorption ability is restored. In order to confirm this, 5 g of each of the compositions of Examples 1 to 5 and Comparative Example 1 was poured into a beaker, and after 30 minutes at 50° C., caprylic/capric triglyceride (InterMed) set with artificial sebum, respectively. The oil absorption rate was measured while wetting the trade name Imex MCT 60/40) manufactured in .

Each of the compositions of Examples 1 to 5 and Comparative Example 1 was slowly dropped while measuring the weight of caprica oil (CAPRYLIC/CAPRIC TRIGLYCERIDE) in 5 g, and continued while the sample was absorbed with caprylic/capric triglyceride. Repeat. If caprylic/capric triglyceride is not absorbed, the amount absorbed by each sample is recorded, respectively, and the sebum absorption rate is calculated according to Equation 1 below.

[Equation 1]

Sebum absorption rate (%) = Final absorption of caprica oil (CAPRYLIC/CAPRIC TRIGLYCERIDE) of the sample (unit g)/ Initial weight of the sample (5 g) X 100 (%)

The measurement results of the sebum oil absorption for Examples 1 to 5 and Comparative Example 1 are shown in Table 2 below.

Example 1 Example 2 Example 3 Example 4 Example 5 Comparative Example 1 Sebum absorption (%) 21 19 15 14 15 (Unable to measure due to separation of formulation)

As shown in Table 2, it can be seen that Examples 1 to 5 have excellent sebum absorption rates, whereas Comparative Example 1 cannot measure the sebum absorption rate because the formulation is separated.

[Test Example 2] Formulation stability measurement

Each of Examples 1 to 5 and Comparative Example 1 were placed in a tube container in an upright position, left at a temperature of 55° C. for at least 2 weeks, and then discharged to observe the state of the formulation.

If only the oil was separated according to the viscosity drop, or if a shape in which the oil was separated on the skin side appeared during application to the skin, the formulation was judged as “separation”, and when this problem was not observed, it was judged as “stable”.

The measurement results of whether the formulation was separated for Examples 1 to 5 and Comparative Example 1 are shown in Table 3 below.

Example 1 Example 2 Example 3 Example 4 Example 5 Comparative Example 1 Whether the formulation is separated stability stability stability stability stability separation
