HYDROGEL FORMING COMPOSITION AND HYDROGEL PRODUCED THEREFROM

摘要

There is provided a hydrogel having a self-supporting property that can be produced only through mixing at room temperature, and there is provided a method by which the hydrogel can be manufactured by using industrially easily available raw materials. A hydrogel-forming composition that is capable of forming a hydrogel having a self-supporting property, the hydrogel-forming composition characterized by comprising: a water-soluble organic polymer (A) having an organic acid salt structure or an organic acid anion structure; a silicate salt (B); and a dispersant (C) for the silicate salt, having a weight average molecular weight of 200 to 20,000 and having hydrolysis resistance.
