  • Particulate fabric softener comprising ethylenediamine fatty acid amides and method of making
    Patent number: 8507425
    Abstract: 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.
    Type: Grant
