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.

Composition emmagasinant l'énergie thermique et méthode permettant de réduire les défaillances par rupture pendant un cycle de congélation engagé à l'intérieur de systèmes qui contiennent des matériaux dont la phase aqueuse se modifie. La composition décrite dans cette invention comprend à peu près de 60 à 96,5 pour cent d'eau en poids, environ de 3 à 40 pour cent d'un mélange de tensioactifs non-ioniques hydrosolubles, en particulier des éthoxylates d'alcool, et de préférence un tensioactif anionique dans une proportion suffisante pour limiter la séparation de phase que subit la composition aux températures élevées.
