From the results of Examples 1 to 11 and Comparative Examples 1 to 3 shown in Tables 2 to 5, when producing an emulsion composition containing silicone and a swellable clay mineral, the solubility parameters of silicone and the silicone were previously determined. A silicone derivative having a difference of 1 or less and a swellable clay mineral are mixed to prepare a dispersion in which the swellable clay mineral is dispersed in silicone, and the dispersion and other components are mixed and dispersed to emulsify. By adjusting the composition and impregnating with this emulsified composition, it not only cleans the skin, gives a refreshing feeling, suppresses the smell of sweat, but also makes the skin not whiten and comfortable without leaving a sticky feeling It has been found that it is possible to provide a sheet-like cosmetic material that can provide a smooth feeling. In addition, since this emulsion composition does not show separation of oil such as silicone in the upper layer portion and the clay mineral can be uniformly dispersed, aggregation of the swellable clay mineral can be surely prevented, and stability over time can be improved. It turned out to be excellent.
Furthermore, according to Examples 3 to 8, it was found that the water-insoluble powder having a water absorption amount of 1 ml / g or more was further improved to improve the smooth feeling after wiping.
On the other hand, Comparative Example 1 is a case where an emulsified composition was prepared without containing silicone, Comparative Example 2 was a case where an emulsified composition was prepared without containing a silicone derivative, and Comparative Example 3 was Since the difference in SP value between the silicone and the silicone derivative is more than 1, the skin is not whitened, but the sticky feeling remains and the sheet-like cosmetic is inferior to the dry feeling. In addition, it was found that an oily component such as silicone was separated in the upper layer part, the clay mineral was aggregated, and the emulsion composition was inferior in stability over time.
