ABSTRACT:
An article suitable for conditioning fabrics in a tumble dryer, comprising a combination of a substrate and a fabric-conditioning composition, the substrate comprising a porous material having a void volume of more than 90% and a cell count of more than 250 cells per cm, the fabric-conditioning composition comprising a fabric-softening material. The claimed article can spontaneously and consistently be adhered to the tumble dryer wall for one or more drying cycles. The moment at which the substrate no longer adheres to the tumble dryer wall coincides with the moment whereupon the amount of conditioning material which is released per drying cycle is insufficient to effect a satisfactory conditioning benefit.
