Abstract
A disposable personal cleaning product comprises a thin substrate, preferably open celled polyurethane foam, from 1-5 mm thick having dispersed throughout its cross-section a detergent composition comprising a non-ionic alcohol ethoxylate and a fatty acid soap, preferably 90-10% by weight of the former and 10-90% by weight of the latter, the ratio of detergent composition to substrate being between 2:1 and 10:1 by weight. The substrate may be provided with slits or similar openings which may be engaged by a user's fingers to enable the product to be maintained in an open or spread condition during use.

A disposable personal cleaning product comprising a substrate consisting of a sheet of open celled foam structure from 1-5 mm thick having dispersed throughout its cross-section a detergent composition comprising a non-ionic alcohol ethoxylate and a fatty acid soap.
A disposable personal cleaning product comprising a substrate consisting of a sheet of open celled polyurethane foam from 1-5 mm thick having dispersed throughout its cross-section a detergent composition comprising 90-10% by weight of a non-ionic alcohol ethoxylate and 10-90% by weight of a fatty acid soap, the ratio of detergent composition to substrate being between 2:1 and 10:1 by weight.
A personal cleaning product comprising an open celled substrate of thin sheet-like form provided with through openings disposed at and confined to peripheral regions thereof, said openings being positioned for ready engagement by a user's fingers to enable the product to be maintained in an open or spread condition during use, and the remaining surface area of said substrate being unbroken.
A method of producing a disposable personal cleaning product comprising impregnating a continuously moving sheet of open-celled foam from 1-5 mm thick with a detergent composition comprising a non-ionic alcohol ethoxylate and a fatty acid soap in a melted condition by compressing the foam sheet, applying the melted detergent composition, and allowing the sheet to expand to draw the composition into and disperse it throughout the cross-section of the foam structure.
