    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.

    Abstract translation: 已经暴露于低温和“凝胶化”的水性液体织物软化组合物可以被回收,并且通过将组合物加热到组合物的克拉夫特温度以上然后施加剪切而将原始分散体重整。 需要非常轻的剪切作用才能使组合物再次自由流动。 可以加入电解质以帮助恢复。 该过程可以使用许多不同种类的加热,并且该方法可以应用于包装和散装产品。
