A cold pack which comprises a composition containing a combination of water and at least one other compound where the combination has a melting (and freezing) temperature above zero degrees Celsius and preferably between 1 and 15 degrees Celsius. The novel cold pack nevertheless maintains almost all of the heat capacity of a similar cold pack using water. Typically the combination is an aqueous clathrate high melting eutectic containing over 90 weight percent and usually over 95 weight percent water. The invention further includes the method of using the cold pack for cooling of a material by freezing the contents of the cold pack and placing it in proximity to the material to be cooled. |
