The sheet-shaped cosmetics of Examples 1 and 2 shown in Table 1 did not drip even when applied to the skin, had good adhesion to the sheet, and had an excellent stickiness after the sheet was peeled off. On the other hand, (A) the sheet-shaped cosmetics of Comparative Examples 1 and 2 containing no hydrophobically modified polyether urethane have remarkable dripping when applied to the skin, and also have adhesiveness and a sticky feeling after the sheet is peeled off. I couldn't get it. Examples 3 and 4 contain ascorbic acid glucoside as a salt-type whitening agent, but as in Examples 1 and 2, there is no dripping even when applied to the skin, the sheet adheres well, and the sheet is used. It had an excellent feeling of stickiness after being peeled off. On the other hand, (A) the sheet-like cosmetic of Comparative Example 3 containing no hydrophobically modified polyether urethane has remarkable dripping when applied to the skin, and also provides adhesion and a sticky feeling after the sheet is peeled off. I didn't.

Examples 5 to 8 shown in Table 2 are examples in which isostearic acid is further added in the formulation of Example 1, and Examples 9 and 10 are examples in which the amount of (A) hydrophobically modified polyether urethane is reduced. There was no dripping even after sticking, and the stickiness after peeling off the sheet was excellent, and despite the high adhesion of the sheet, there was no stickiness after peeling off. Moreover, since the kinematic viscosity is low in spite of the high static viscosity, it was possible to prevent the skin from becoming slimy after the sheet was peeled off.

Example 11 shown in Table 3 is an example in which the amount of the activator is reduced, Examples 12 and 13 are examples in which polyoxyethylene hydrogenated castor oil is added, and Example 14 is an example in which dimethicone having a kinematic viscosity of 50 mm ² / s or more is added. Example 15 is an example in which diglycerin is added, and Example 16 is an example in which dipropylene glycol is added. However, even if these are also applied to the skin, there is no dripping, and the feeling of stickiness after peeling off the sheet is excellent. Although the sheet had high adhesion, it was not sticky after being peeled off.
