ABSTRACT:
Disclosed herein is a fabric softener-containing article comprising a fabric softener impregnated into an open-celled reticulated urethane foam; said impregnated foam being compressed to form a sheet or wafer. The fabric softener also acts as a solid binder which maintains the reticulated urethane foam in compressed form. The compressed sheet-like compositions are especially advantageous in that they are only 1/5 to 1/15 the size of comparable materials containing equivalent loadings of fabric softener. During the laundry wash cycle the water-dispersible fabric softener is released allowing the foam to slowly rebound to substantially its original uncompressed shape.
