Document Type and Number:
Japanese Patent JP6650363
Kind Code:
B2
Abstract:
This cooling tool includes a cooling composition that contains water, an inorganic salt, a thickener, and a pH indicator. The cooling composition only includes, as the inorganic salt: (S1) a combination of a phosphate, a monohydrogenphosphate, and another inorganic salt; (S2) a combination of a phosphate, a dihydrogenphosphate, and another inorganic salt; (S3) a combination of a monohydrogenphosphate, a dihydrogenphosphate, and another inorganic salt; or (S4) a combination of a dihydrogenphosphate and another inorganic salt. The other inorganic salt is none of the phosphate, the monohydrogenphosphate, and the dihydrogenphosphate, and the total content of the inorganic salt in the cooling composition is 20 to 35% by mass. The pH (β1) of the cooling composition when all the components other than the phosphate, the monohydrogenphosphate, the dihydrogenphosphate, and water are substituted with water, and the pH (β2) of the cooling composition when all the components other than the other inorganic salt, the thickener, and water are substituted with water satisfy formula (10). 11.0≤pH(β1)+pH(β2)≤17.2 (10)
