Quench cooled particulate fabric softening composition |
(57) A detergent-compatible, dryer-released, quench cooled fabric softening composition
prepared by quench cooling molten fabric softener on a cooling device, preferably
a moving cooled belt. Fabric softener particles made therefrom are harder and have
a more complex differential scanning calorimetry curve than a comparable nonquenched
or prilled fabric softener. The average particle of this invention preferably has
at least one flat or smooth surface covering at least about 10% up to 100% of its
total surface area. The particulate particles are easier to coat and easier to handle.
