摘要： The present invention relates to a heat transfer medium composition which contains water, a glycol, alcohol and/or glycol ether as a main ingredient and a pH buffering agent. The composition provides improved and long lasting buffering in actual use to maintain the pH value of the medium within the appropriate range of pH 6 to pH 10. The pH buffering agent is prepared of an alicyclic compound where two members selected from among carboxyl and its salts are bonded to a ring-constituting carbon atom, or at least two members selected from the group are respectively bonded to as many neighboring carbon atoms. Alternatively, the pH buffering agent is prepared of a heterocyclic compound in which at least one ring-constituting carbon atom of the alicyclic compound is substituted by a nitrogen or oxygen atom, where two members selected from the group are bonded to a ring-constituting carbon atom, or at least two members selected from the group are respectively bonded to as many neighboring carbon atoms.
