Particulate fabric softener comprising ethylenediamine fatty acid amides and method of making

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 at a heating rate of 2° C./min;
