Cosmetic gel sheet and manufacturing method thereof

A cosmetic gel sheet, wherein the cosmetic gel sheet consists essentially of a carboxy group-containing water-soluble polymer, polyalcohol, acid, water, and optionally, a valuable component, and water content is 30% by weight or less,

• wherein the carboxy group-containing water-soluble polymer is carboxy group-containing polysaccharide,
• wherein a content of the polyalcohol is from 10 parts by weight to 1,000 parts by weight based on 1 part by weight of the carboxy group-containing water-soluble polymer,
• when an aqueous solution containing the carboxy group-containing water-soluble polymer, the polyalcohol, and the acid as essential components is dried to manufacture the gel sheet, content of the acid is appropriate for setting pH of the aqueous solution to 2.0-4.5,
• wherein the valuable component is selected from the group consisting of whitening components, anti-wrinkle components, anti-inflammatory components, blood circulation promoting components, anti-microbial components, anti-pruritic components, vitamins and derivatives thereof, anti-oxidative components, anti-allergic components, pigment, and fragrances, and
• wherein rupture stress of the cosmetic gel sheet is 0.05 N/cm2 or more.
