Embodiment 1

[0058] A colorless solution was prepared comprising the following components by weight:

[0059] - 35% of ethylhexyl acrylate / vinyl acetate / acrylic acid copolymer with a molecular weight of 1,500,000;

[0060] - 52% ethyl acetate;

[0061] - 3% 5-octylsalicylic acid, and

[0062] - 10% of the product sold by ATOCHEM under the trade name ORGASOL(R).

[0063] A mask-shaped porous polyethylene sheet with a thickness of about 30 μm was impregnated with a sufficient amount of the above-mentioned solution, and after the ethyl acetate evaporated, the obtained face-painting sheet was applied to the face and then removed after a few minutes. Skin was found to be smoother and clearer after removing the patch. Moreover, due to the presence of ORGASOL, the dull complexion becomes natural and also gives a soft and pleasant feeling.

Embodiment 2

[0065] A colorless solution was prepared comprising the following components by weight:

[0066] - 31% ethylhexyl acrylate / vinyl acetate / acrylic acid copolymer with a molecular weight of 1,500,000;

[0067] - 46% isopropanol;

[0068] - 3% 5-n-octylsalicylic acid;

[0069] -10% kojic acid; and

[0070] -10% of ATOCHEM under the trade name ORGASOL  products for sale.

[0071] A veneer sheet similar to that described in Example 1 was prepared from the above solution. The cosmetic sheet can not only provide effective exfoliation to the skin, but also obtain satisfactory facial gloss due to the presence of kojic acid.

Embodiment 3

[0073] A colorless solution was prepared comprising the following components by weight:

[0074] - 37% copolymer of ethylhexyl acrylate / vinyl acetate / acrylic acid with a molecular weight of 1,500,000;

[0075] - 50% isopropanol;

[0076] - 3% 5-n-octanoyl salicylic acid;

[0077] - 0.5% essential oil of Geranium;

[0078] -0.5% essential oil of citron; and

[0079] -9% of ATOCHEM under the trade name ORGASOL  products for sale.

[0080] Decorative sheets consisting of nonwoven, porous and honeycomb fabrics were prepared by the method as described in Example 1. Apply the patch to the area of ​​the skin to be cleansed for about 15 seconds, then remove it, visible due to ORGASOL  The deposition on the skin surface and the emollient action of the essential oils of Geranium and Citron leave the skin visibly cleansed and softer.
