PROBLEM TO BE SOLVED: To provide a low-temperature retaininer and a sedimentation inhibitor which can reduce the average particle sizes of ice crystals and gives the liquid ice (ice slurry) good fluidity. SOLUTION: An aqueous solution of a lower alcohol containing (1) an oligomeric polycarboxylic acid, (2) sorbic ester or salt, (3) a polyhydric alcohol, (4) an aliphatic acid or its salt, (5) an anionic surfactant and/or (6) a sullfur-free triazole is used as a low-temperature retainer. In addition, a high-dispersion silicic acid is used as a sedimentation inhibitor in an aqueous solution of a lower alcohol used as a liquid-ice mixture. |
