Abstract:
The present invention relates to a composition for a hydrogel sheet including a cellulose ether, a gelling agent, and a gelling promoter, a hydrogel sheet prepared therefrom, and a method of preparing the hydrogel sheet. According to the present invention, the composition for a hydrogel sheet can be used to prepare a hydrogel sheet capable of maintaining the shape thereof without a support by limiting a type of the gelling agent and/or a viscosity of the cellulose ether included in the composition.

Claim (Index 23):
A method of preparing a hydrogel sheet according to  claim 19 , the method comprising:\n preparing a composition for a hydrogel sheet by mixing a cellulose ether, a gelling agent, and a gelling promoter; preparing a hydrogel sheet composition solution by inputting the composition for a hydrogel sheet into hot water and performing stirring; deaerating the hydrogel sheet composition solution by allowing air bubbles contained therein to rise; casting the deaerated hydrogel sheet composition solution in the form of a sheet; and gelating the casted sheet type hydrogel sheet composition solution.
