ABSTRACT:
An article for delivering a cleaning composition to a wash water, preferably for laundering clothes, is formed from a flexible substrate folded into an S-shaped construction. Within one region of the folded substrate is positioned a detergent composition that includes a surfactant and builder in the form of a paste having adhesive strength sufficient to bind the two surrounding substrate areas together. In a second region of the folded substrate separate from that occupied by the detergent composition, there is a further composition, adhesive in nature, containing a component which may be a bleach, bleach precursor, enzyme and/or fabric softener. No other bonding is present between the three substrate area flaps constituting the S-shaped construction. The compositions between the substrate areas are easily released to the wash water when the article is placed therein.
