[0111] (1) Preparation of an aqueous solution of a polymer compound

[0112] Using a high molecular compound: fully saponified polyvinyl alcohol (manufactured by Kuraray Co., Ltd; degree of saponification: 99% or more), which was dissolved in water to prepare an aqueous solution having a concentration of 15%.

[0113] (2) Hydrophilic treatment of non-woven fabrics

[0114] A polypropylene nonwoven fabric (manufactured by Shinwa Corp.) as a base sheet was immersed in an aqueous solution containing a hydrophilizing agent (alkyl phosphate salt, manufactured by Takemoto Oil & Fat Co., Ltd.) , followed by drying to obtain a hydrophilized nonwoven fabric. The degree of hydrophilicity of the hydrophilized nonwoven fabric was 65.

Abstract

The present invention is related to the field of cosmetic sheets which are used by adhering it to the skin to diminish fine wrinkles and spots of the face. According to the present invention, cosmetic sheet is provided which comprises a base material sheet; a peelable nanofiber sheet provided on a surface of the base material sheet; and a cover sheet provided on a surface of the nanofiber sheet, where hydrophilization treatment is performed on the base material sheet and the nanofiber sheet is formed by an electrospinning method.

Description

technical field [0001] The present invention relates to a cosmetic sheet applied to the skin for reducing the appearance of fine wrinkles and facial blemishes. Background technique [0002] Japanese Laid-Open No. 2008-179629 (Patent Document 1) proposes a cosmetic sheet applied to the skin for reducing the appearance of fine wrinkles and facial spots. [0003] The cosmetic sheet is obtained by mixing cosmetics into a solution containing a polymer compound dissolved in water or a solvent, followed by electrospinning the resulting liquid. [0004] However, the cosmetic sheet thus obtained is very thin, which makes handling difficult since it is difficult to hold the sheet and apply it evenly to the face. [0005] Japanese Laid-Open No. 2012-12339 (Patent Document 2) discloses a cosmetic in the form of a cosmetic sheet having a sheet composed of nanofibers obtained by an electrospinning method. [0006] The cosmetic in the form of a cosmetic sheet is a nanofibrous sheet compr...
