(57) [Summary] [PROBLEMS] To have biodegradability, high safety, high gel strength after water absorption to the extent that it can be practically used without problem, and sufficient water absorption and water absorption speed. To provide an excellent water-absorbing material. A water-absorbing material composed of guar gum and carrageenan, wherein the water absorption of a 0.9% by mass aqueous sodium chloride solution is 20 times or more its own weight, and the gel strength in a 30-fold water absorbing state of the aqueous solution is 15 times. 2,000 × A water-absorbing material characterized by having a density of 10 -7 N / mm 2 or more. |
