<p>The present invention relates to a thermal energy storage composition and a method for reducing rupture failures during freezing cycles of container devices holding aqueous phase change materials. The thermal energy storage composition of the present invention contains about 60 to about 96.5 weight percent water, about 3 to about 40 weight percent of one or a mixture of water-dispersible non-ionic surfactants, particularly alcohol ethoxylates, and preferably an anionic surfactant in an amount sufficient to reduce phase separation of the composition at elevated temperatures.</p> |
