A heat carrier composition which comprises water, a glycol, an alcohol, or a glycol ether as the main component and fluctuates little in pH value even in long-term use. The composition is characterized by containing a pH buffer comprising an alicyclic compound in which one of the ring-constituting carbon atoms has, bonded thereto, two groups of one or two kinds selected among carboxymethyl and salts thereof or in which at least two adjacent carbon atoms each has, bonded thereto, one group independently selected among carboxymethyl and salts thereof. |
