By co-blending the ingredient (A) and the ingredient (B), the skin after using the sheet cosmetic has a low friction feel and no powdery feel (dryness or sticking due to powder) (smoothness). Feeling) can be given. By blending ethanol [component (C)] in a specific ratio, the component (A), which is highly hydrophobic and is not normally blended in an aqueous medium as a powder, is dispersed in the component (D). Is possible. In addition, quick-drying property can be imparted.

Further, the sheet cosmetic of the present invention is a sheet cosmetic and can be used to wipe off the skin. As a result, the cosmetic composition of the present invention can be applied evenly to the skin in a small amount, and the sweat and sebum on the skin can be wiped off and applied, so that the skin does not become slimy after use. ..

Hereinafter, the present invention will be described in more detail based on Examples, but the present invention is not limited to these Examples. The blending amount shown in the table is the blending amount of each component (that is, the blending amount of the active ingredient in each raw material, so-called pure content), and is represented by "mass%" unless otherwise specified.

Examples 1 to 24, Comparative Examples 1 to 5
Using each component (components (A) to (D)) shown in the table, each cosmetic composition of Examples and Comparative Examples was prepared by a conventional method. Further, the cosmetic composition is impregnated into a spunlace non-woven fabric having a grain size of 40 g / m ² at a ratio of 290 parts by mass with respect to 100 parts by mass of the non-woven fabric, and each sheet of Examples and Comparative Examples is made up. A material (sheet size: 14 cm × 20 cm, rectangular) was prepared.

(Evaluation)
Each cosmetic composition and each sheet cosmetic obtained in Examples and Comparative Examples were evaluated as follows. The evaluation results are shown in the table. In addition, "-" in the table indicates that the evaluation was not performed.

(1) Smoothness With one sheet of cosmetics obtained in each of the examples and comparative examples, the inside of one forearm was wiped back and forth three times, and the wiped part was evaluated for the smoothness immediately after wiping, and the following judgment was made. Judgment was made according to the criteria. The above evaluation was carried out under constant temperature and humidity conditions of 25 ° C. and 50% humidity RH.
[Criteria for smoothness]
◯ (Good): The skin after use feels low in friction, and the skin after use does not feel powdery (sticking due to powder or dryness due to powder), and an appropriate moisturizing feeling is felt.
× (Defective): The skin after use does not feel low friction, or the skin after use feels powdery (powder stuck or dryness due to powder).

(2) Non-slimyness In the evaluation of the above-mentioned smoothness, the non-slimyness when the sheet cosmetic was wiped off was evaluated, and the determination was made according to the following criteria.
[Criteria for non-sliminess]
○ (Good): Does not feel slimy (greasy feeling) on the skin after use.
× (Defective): The skin feels slimy (greasy) after use.

(3) Whiteness In the evaluation of the smoothness, the whiteness was visually evaluated for the wiped portion 10 minutes after the sheet cosmetic was wiped off. The above evaluation was carried out under constant temperature and humidity conditions of 25 ° C. and 50% humidity RH. Judgment was made according to the following evaluation criteria.
[Criteria for whitening]
○ (excellent): There is no whitening on the coated part.
X (defective): Whitening occurs on the entire coated portion.

(4) Oil floating Each cosmetic composition obtained in Examples and Comparative Examples was put into a glass container and allowed to stand at 25 ° C. for 10 minutes, and then the cosmetic composition was visually observed to form an oil phase. Was judged according to the following evaluation criteria. The results are listed in the table.
[Oil float]
○ (Good): There are no oil droplets on the upper layer.
× (defective): Oil droplets are present in the upper layer.

As shown in the table, according to the sheet cosmetic of the present invention, a smooth feeling could be imparted. Furthermore, it was excellent in non-sliminess, and there was no whitening or oil floating. On the other hand, when the component (A) was small (Comparative Example 1), oil floating occurred. When the component (A) was excessive (Comparative Example 2), the smoothness was poor and whitening also occurred. Further, even if the content ratios of the component (A) and the component (B) are appropriate values, when the mass ratio of the component (B) to the component (A) is high (Comparative Example 3), oil floating occurs. occured. When the component (B) was small (Comparative Example 4), the smoothness was poor and whitening also occurred. When the component (B) was excessive (Comparative Example 5), the smoothness was poor and the lack of sliminess was also poor.
