Experimental Example

Experimental Example 1 - Formulation stability of powder form cosmetic composition

All of the cosmetic compositions of Examples 1 to 2 and Comparative Example 2 had no problem in shape, but in the case of Comparative Example 3 in which the content of the hydrophobic powder was 2% by weight, the water droplets not covered by the powder were scattered between the particles of the powder formulations (Fig. 5A). Finally, it was confirmed that the water and the powder were separated and the state of the powder could not be maintained (Fig. 5B).

Experimental Example 2 - Comparison of degree of coloring (naturalness)

To evaluate the degree of natural make-up, it was observed whether or not the cosmetic composition according to Example 1 of the present invention was applied after 2 hours (without rinsing) after application and the cosmetic composition according to Comparative Example 1 (peel off gel type) After 2 hours of application, peel-off was observed to determine the coloration

1, when the powder-form cosmetic composition according to Example 1 is applied to the skin, it is possible to make a natural make-up even after washing. However, when the gel type of Comparative Example 1 is applied and then peeled off, It was confirmed that the boundary between the part and the uncoated part was clear and the makeup was unnatural.

Experimental Example 3 - Evaluation of color persistence

In order to determine the degree of persistence of coloration, the powder-form cosmetic composition of Example 1 was applied to the inside of the arm and washed after 8 hours. Photographs were taken immediately after washing and 3 days later.

Referring to FIG. 2, it can be seen that the coloration lasts for a long time even after clearing the makeup because there is not a large difference immediately after and after 3 days of washing.

Experimental Example 4 - Comparison of degree of coloring (Comparison according to hydrophobic powder content)

In order to examine the degree of coloring according to the hydrophobic powder content, the powder-form cosmetic compositions of Examples 1 to 3 and Comparative Example 2 were applied to the inside of the arm and washed after 8 hours. Immediately after washing, photographs were taken and the degree of pigmentation on the skin was compared.

Referring to FIG. 3, as the content of the hydrophobic powder is increased, the coloration is reduced. As a result, the coloring effect is brought about by the skin contact with the water containing the tannin component. When the content of the hydrophobic powder is increased, It can be confirmed that it is a phenomenon.

In particular, referring to FIG. 4, when the content of the hydrophobic powder is 40% by weight, the coloration becomes very thin. As a result, it is confirmed that the excessive amount of the powder does not cause a problem in the shape of the powder,
