[0082] (Examples 1 to 11, Comparative Examples 1 to 6: Detailed evaluation of sheet texture) The sheet-shaped cosmetics having the configurations of the respective examples shown in Tables 1 and 2 were further evaluated for the texture of the sheet by the following method. Tables 4 and 5 show the evaluation results. (Seat texture) (Evaluation method) (6) Sheet texture (smoothness when touched with a finger) Three professional evaluators evaluated the smoothness of the sheet surface when they touched it with their fingers, according to the following five-grade criteria. Tables 4 and 5 show the total scores of the three participants. 5: Feels visibly smoother 4: Feel smooth 3: Feels a little smooth 2: Not very smooth 1: Does not feel visibly smooth (7) Texture of the sheet (when applied to the face) Three professional evaluators applied the sheet to the face and evaluated the difficulty of feeling unevenness and roughness of the sheet itself when the face was moved according to the following five-level criteria. Tables 4 and 5 show the total scores of the three participants. 5: No obvious feeling 4: I don't feel it 3: hardly felt 2: Slightly feel 1: I feel it clearly

[0085] (Examples 12 and 13) A composition of each example was prepared in the same manner as described above in Example 1, except for the formulation shown in Table 6, and the viscosity was measured. A sheet base material was impregnated with the obtained composition in the same manner as in Example 1 to obtain a sheet-shaped cosmetic of each example. (Evaluation method) The texture of the sheet was evaluated by the methods (6) and (7) in Example 1 above. Permeability and adhesion, persistence of moisturizing sensation (moisturizing persistence), dripping, and stickiness were evaluated by the methods (2) to (5) above in Example 1, respectively, except that they were evaluated by three professional evaluators. evaluated. Table 6 also shows the evaluation results.
