Abstract

A heat storage material composition having a melting temperature utilized for control of an optional management temperature, providing no variation in melting behavior and solidification behavior, and having a constant melting temperature. The heat storage material composition consists primarily of a mixture of a higher alkane having carbon number of 9 to 24 and a higher alcohol having carbon number of 6 to 20, and the mixture has a substantially single melting peak in DSC curve measured by a differential scanning calorimeter (DSC).
