ABSTRACT:
Aqueous liquid fabric softening compositions that have been exposed to low temperatures and "gelled", can be recovered and the original dispersion reformed by heating the compositions to above the Krafft temperature of the composition and then applying shear. Only very light shearing action is required to make the compositions free-flowing again. Electrolyte can be added to aid in recovery. The process can use many different kinds of heating and the process can be applied to both packaged and bulk products.
