<P>PROBLEM TO BE SOLVED: To obtain a gelatin gel that has improved mechanical properties and heat resistance without impairing excellent elasticity, sustained release properties, adhesiveness and temperature retention and surely controls change in shape, change in properties, solidification of surface and growth of mold. <P>SOLUTION: The gelatin gel is prepared by dissolving a gelatin in a polyhydric alcohol as a solvent, allowing the solution to stand and cooling the solution. Ethylene glycol or propylene glycol is used as the solvent. A crosslinking agent may be added, if necessary. An aqueous solution of glutaraldehyde, a diluent of glutaraldehyde diluted with an organic compound, a bifunctional or polyfunctional epoxy compound such as ethylene glycol diglutar ether or a diluent of a bifunctional or polyfunctional epoxy compound diluted with an organic compound may be used as the crosslinking agent. <P>COPYRIGHT: (C)2007,JPO&INPIT |
