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.
