Abstract
Concentrated, liquid fabric-softening compositions containing 15-60% of a cationic fabric-softening agent, and an aqueous medium, are prepared by inclusion therein of an effective amount of polymer, such as polyethyleneglycol with a molecular weight of 6,000. These compositions are water-dispersible and pourable, and can be easily dosed into the rinse cycle of a washing process, e.g. by means of automatic dosing devices in the washing machine.
