PURPOSE:To provide a simple cooling agent permitting to persist a cooling effect thereof for a long time and capable of being stored and used also in summer without any trouble by keeping the powder of a substance absorbing heat when dissolved in water and a water-absorbing polymer in a mutually separated state so as to enable to be mixed with each other when used. CONSTITUTION:(A) 100 pts.wt. of a substance absorbing heat when dissolved in water and preferably comprising a mixture of ammonium nitrate and urea and (B) preferably 70-100 pts.wt. of a water-absorbing polymer derived from starch, cellulose or synthetic polymer and swelled by absorbing an aqueous solution of an inorganic salt, preferably anhydrous sodium sulfate or sodium sulfate hydrate are kept in a mutually separated state so as to enable to be mixed with each other when used, thus providing the objective cooling agent. |
