A particulate fabric softening composition, comprising one or more ethylenediamine fatty acid diamides and one or more quaternary ammonium salt fabric softeners, the composition having an exothermal transition at a temperature between 60 and 90 °C with an exothermal transition enthalpy of more than 5 J/g measured by DSC with a heating rate of 2°C/min, can be press shaped to multiple use, dryer added fabric softening articles having high initial surface hardness. The fabric softening composition can be made by cooling a molten mixture comprising one or more ethylenediamine fatty acid diamides and one or more quaternary ammonium salt fabric softeners to a temperature of 40 °C or less at a high cooling rate.
