    • PURPOSE: A hydrogel composition for a holding object is provided to maintain the shape without a support and maintaining stable properties when impregnating the composition into a drug material. CONSTITUTION: A hydrogel composition for holding a mask substrate comprises 0.1-10 weight% of a crosslinking agent, 0.2-6 weight% of a gelated polymer, 0.5-20 weight% of a polyhydric alcohol, and 70-90 weight% of purified water. The crosslinking agent is an acrylic cross-linked polymer or a mixture thereof. The mixture of the cross-linked polymer and the styrene-based copolymer is added with a weight ratio of 2:8-8:2. The gelated polymer is one or more selected from galactomannan, glucomannan, guar gum, Locust bean gum, pluronic, agar, algin, carrageenan, xanthan gum, and gellan. [Reference numerals] (S110) Step of manufacturing an aqueous solution by adding a crosslinking agent in refined water at room temperature and stirring at high temperatures; (S120) Step of manufacturing a hydrogel composition by adding gelated polymer in polyhydric alcohol at room temperature to be dissolved and introducing into the aqueous solution; (S130) Step of compressively coating the hydrogel composition; (S140) Step of manufacturing hydrogel by cooling the compressively coated hydrogel composition at room temperature; (S150) Step of thermally treating the cooled hydrogel;
