Abstract (en)
[origin: EP0334430A2] 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.
