Abstract
A disposable article for interim cleaning of hard surfaces comprises a non-woven substrate, carrying an aqueous cleaning composition loaded onto the substrate at a level less than about 85%, preferably less than 75%, of its absorbence capacity. The aqueous composition comprises: optionally, one or more nonionic surfactants, one or more anionic surfactants or mixture of nonionic and anionic surfactants; a water miscible solvent for oils, (preferably a low molecular weight alcohol or N-methyl-2-pyrrolidone); and an alkalinity agent, such as ammonium hydroxide, in sufficient amount to maintain the pH of the extracted solution within the range of 8 to 12. The non-woven substance is preferably a non-chemically bonded fibrous material.
Claims33
A disposable article for cleaning hard surfaces comprising, as non-woven substrate, a fibrous sheet consisting essentially of cellulosic material, polyolefins, polyester, nylon or mixtures thereof, and having a absorbence capacity for water of at least 200 weight percent, said substrate being impregnated to a level not exceeding about 85% of its absorbence capacity with an aqueous solution comprising
- from about 5 to about 70% by weight of a water miscible solvent for oils, and
- ammonium or an alkali metal hydroxide as an alkalinity agent in an amount sufficient to cause the pH of the extracted solution to be within the range of from 8 to 12.
