Citric acid-piperazine salt was prepared with a molar ratio of acidpiperazine of 2.9. The salt was characterized by thermal calorimetry, 13C NMR and IR spectroscopy. The piperazine content in the salt was 52%. A typical formulation was achieved by mixing the salt with the diglycidyl ether of bisphen
