<Test Example 2>
The cleansing cosmetic 1, Comparative Example 1, and Comparative Example 2 were tested for the ability to remove horn plugs. That is, a total of 30 people in 3 groups were prepared, each group was randomly divided into 3 groups of 10 people, and the three types of cosmetics were assigned to each group. Each panelist treated the right side of the nostril with a sample and performed cleansing. Then, using the horn plug removal sheet, the horn plugs of the nostril portion are firmly peeled off, and the number of horn plugs collected from the left nostril portion is divided by the number of horn plugs collected from the left nostril portion. 1
The removal rate of the square plugs by the sample cosmetic was multiplied by 00. The results are shown in Table 2. From this, it can be seen that the cleansing cosmetic of the present invention is excellent in the effect of removing horn plugs.

The cleansing cosmetic 5 according to the present invention was produced in the same manner as in Example 1 according to the following formulation. This product was evaluated in the same manner as in Test Example 1, ΔE was 0.56, and in the same evaluation as in Test Example 2, the removal rate of horn plugs was 65.9 ± 25.6%.
