1. A gel composition suitable for use in a thermal exchange implement, the gel composition comprising:
(a) a phase-change material, wherein the phase-change material comprises an aqueous salt solution and wherein the aqueous salt solution comprises about 20 wt% of at least one salt; (b) a cross-linkable thickener, wherein the cross-linkable thickener is compatible with the phase-change material, wherein the cross-linkable thickener comprises one or more cross-linkable hydroxyl groups, and wherein the cross-linkable thickener constitutes about 1-2.5 wt% of the gel composition; and (c) a cross-linker for the one or more cross-linkable hydroxyl groups, wherein the cross-linker comprises a boron-containing cross-linker and wherein boron constitutes about 40 to 200 ppm, by weight, of the gel composition. |
