Abstract
Abstract Article for dispensing liquid bleach-softener composition in one or more of the wash, rinse and tumble dry cycles of a fabric laundering process comprising a flexible, form retaining, open cell porous foam substrate, preferably polyurethane, impregnated with a liquid composition containing an effective bleaching and softening amount of water soluble peroxy bleaching agent and water soluble softener, at least 50% by weight of the softener being cationic imide of the imidazolinium or pyridinium type in a weight ratio of softener to bleach of about 5:7 to 5:1.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
88 words
An article for dispersing liquid bleach-softener composition in one or more of the wash, rinse and tumble dry cycles of a fabric laundering process comprising a flexible, foam retaining, open cell polymeric foam substrate impregnated with a liquid composition containing an effective bleaching and softening amount of water soluble peroxy bleaching agent and water soluble softener of the quaternary ammonium and/or heterocycle imide type in a weight ratio of softener to bleach of about 5:7 to 5:1, at least about 50% of said peroxy bleach being hydrogen peroxide.
Claim 2
Dependent Claim
88 words
An article for dispersing liquid bleach-softener composition in one or more of the wash, rinse and tumble dry cycles of a fabric laundering process comprising a flexible, foam retaining, open cell polymeric foam substrate impregnated with a liquid composition containing an effective bleaching and softening amount of water soluble peroxy bleaching agent and water soluble softener of the quaternary ammonium and/or heterocycle imide type in a weight ratio of softener to bleach of about 5:7 to 5:1, at least about 50% of said peroxy bleach being hydrogen peroxide.
