PURPOSE:To obtain the titled composition capable of significantly preventing supercooling phenomena, by incorporating water as the chief material with e.g. activated carbon as the nucleating agent for supercooling prevention. CONSTITUTION:The objective composition can be obtained by incorporating (A) water as the chief material with (B) pref. 0.05-.10wt.% of at least one kind of matter as the nucleating agent for supercooling prevention, selected from activated carbon, graphite and charcoal. Preferably, this composition is further incorporated with a water-soluble polymer as the thickening agent (e.g., polyacrylic acid, PVA, CMC) and a salt as the agent for making crystal finer.
