The sheet-shaped cosmetic of the present invention is preferably used in a state accommodated in a package. There is no restriction|limiting in particular as said package, The thing normally used for sheet-like cosmetics can be used, selecting suitably.

-purpose-

The use of the sheet cosmetic of the present invention is not particularly limited as long as the skin is wiped off, and can be appropriately selected depending on the purpose. Since it is good, it can be suitably used, for example, a face sweat wiping sheet, body sweat wicking sheet, body deodorant sheet, foot wiping sheet, care cleaning sheet, sebum wiping sheet, drowsiness sheet, etc. In particular, from the viewpoint of excellent dryness of the skin and the durability of the dryness, it can be preferably used for a face sweat wiping sheet, a body sweat wiping sheet, and a body deodorant sheet.

(Example)

Hereinafter, the present invention will be described in more detail based on Examples and Comparative Examples, but the present invention is not limited to the following Examples.

Content of each component described in an Example and a comparative example is represented by mass %, and all are the values which converted the pure part. However, about (D)component, it is content (mass %) which converted the actual compounding quantity (mass %) of 95 volume% ethanol into absolute ethanol using 95 volume% ethanol.

In addition, mass ratio (A)/(B) of content of (A) component and the flow volume of (B) component round off 2nd place after a decimal point, and calculated|required and described it to the 1st place after a decimal point.

(Examples 1 to 16, and Comparative Examples 1 to 7)

In the composition shown in Tables 1 to 6 below, after dispersing and dissolving components other than hydrophilic inorganic powder, sodium hydroxide, and water (purified water) in ethanol, purified water and sodium hydroxide are added, and finally, hydrophilic inorganic powder was added to obtain a liquid cosmetic composition.

The viscosity in 25 degreeC of each said liquid cosmetic composition was in the range of 0.5 mPa*s - 10 mPa*s. In addition, the said viscosity was measured on the conditions for 1 minute at 60 rpm using the BM type|mold viscometer and using the No. 1 rotor.

Each of the obtained liquid compositions is impregnated into the following sheet-shaped substrate so that the mass after impregnation of the liquid cosmetic composition is 5 times (mass ratio (liquid cosmetic composition/sheet-shaped substrate): 4) of the mass before impregnation of the liquid composition Each sheet-shaped cosmetic (body sweat wiping sheet) was produced.

<Sheet shape base material>

・Rayon/PP/PE core-sheath fiber/rayon = (20 g/m)/(20 g/m)/(20 g/m): (60 g/m) (hydrophilic fiber/hydrophobic fiber=67/33, mass ratio) (Daiwa Bow Polytech Co., Ltd.)

<Evaluation>

For each obtained liquid cosmetic composition and each sheet-like cosmetic, "impregnability to a sheet-like base material", "persistence of dryness and dryness", "no cloudiness", "cool feeling", and "stimulation" were performed as follows. None” was evaluated. In addition, since the liquid cosmetic compositions of Comparative Examples 1 to 5 could not be impregnated into the sheet base material, evaluation other than "impregnability to the sheet base material" could not be performed. The results are shown in Tables 1 to 6.

[Impregnation property to sheet-like base material]

The mass of the aggregate remaining on the sieve when 100 g of the liquid cosmetic compositions of Examples 1 to 16 and Comparative Examples 1 to 7 were sieved through a JIS sieve having a sieve hole of 75 µm was measured, and the following evaluation criteria were met. Thus, the impregnability to the sheet-like substrate (hereinafter, may be referred to as “impregnability to the sheet”) was evaluated.

-Evaluation standard-

(double-circle): There is no aggregate on the surface of a nonwoven fabric (aggregate: 0.5 g or less).

○: There are some aggregates on the surface of the nonwoven fabric (aggregates: more than 0.5 g, 1.5 g or less).

(triangle|delta): There is an aggregate on the surface of a nonwoven fabric (aggregate: more than 1.5 g, 2.5 g or less).

x: There are a lot of aggregates on the surface of the nonwoven fabric (aggregates: more than 2.5 g).
