Lane, G A; Rossow, H E; Teot, A S

A thermal energy storage material is described which consists of at least one hydrated inorganic salt having a phase change transition temperature in the range of from greater than about 0/sup 0/C to about 140/sup 0/C, wherein the hydrated inorganic salt or mixture of salts undergoes segregation of its chemical components during repeated cycles of freezing and thawing, and a surface active thickening agent in an amount sufficient to form throughout the storage material a micelle structure of the type that thickens the storage material to prevent the segregation.
