Abstract

A method of softening fabrics where the consumer adds an effective amount of a particulate fabric softening composition comprising fabric softener agent to an automatic dosing dispenser with water, seals the dispenser, and places the automatic dosing dispenser into a washing machine at the beginning of the wash process. The mechanical agitation and/or heat of the wash cycle aids in forming a finely divided emulsion/dispersion of fabric softener agent which is then released from the dispenser during the rinse cycle.
