Title:
COLD INSULATION TOOL
Document Type and Number:
Japanese Patent JP2017057377
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a cold insulation tool easily visible whether cooling condition is at aimed condition or not.SOLUTION: There is provided a cold insulation tool having a composition for cooling containing water, inorganic salt, a thickener and a pH indicator, wherein the composition for cooling contains acidic inorganic salt of which solution shows acidity and phosphate as the inorganic salt, percentage of total content of the acidic inorganic salt and phosphate to the total content of the inorganic salt is 5 to 100 mass%, the composition for cooling contains dihydrogenphosphate and the inorganic salt other than dihydrogenphosphate as the acidic inorganic salt, pKa of the pH indicator is 4.9 to 8.0 and pH (α1) when all contained component other than phosphate, dihydrogenphosphate and water satisfies a relationship represented by the following formula (i) to the pKa. pKa of pH indicator≤pH(α1)≤pKa of pH indicator+1.8 (i).SELECTED DRAWING: None
