PROBLEM TO BE SOLVED: To provide a new gelling composition capable of facilitating, for example, a dispensing operation or a mixing operation with other components for a solution obtained by adding water to a gelling composition. And According to the present invention, for example, a gelling composition that requires a metal ion for gelation and is used by transferring from a sol state to a gel state at room temperature without adding water and performing heating and cooling operations. The sol solution prepared by adding water to the gelled composition, after hydration, maintains the sol state for at least 90 seconds in the presence of metal ions, and has a viscosity of 1 minute after hydration for 1 minute after hydration. A delayed gelling composition characterized by reaching a viscosity of 2 to 1.5 times and exhibiting a gel state within 6 hours after hydration can be mentioned.
