ABSTRACT:
A cleansing article along with its method for manufacture are provided. The cleansing article comprises a porous pad which includes a controlled detergent release composition comprising: polyacrylamide (preferably having a weight average molecular weight greater than 200,000) and detergent preferably blended to provide a weight ratio of polymer solids:detergent solids between about 1:9 and about 1:100 and more preferably between about 1:12 and about 1:30. The method comprises preparing a coatable polymer/detergent blend comprising polyacrylamide, detergent and a liquid vehicle which on drying forms a controlled detergent release composition, applying said coatable blend to a porous pad, and drying said blend to provide said controlled detergent release composition. The controlled detergent release composition is substantially retained within the pad for subsequent use and thereafter slowly released when used.
