Abstract
A disposable article for light cleaning of hard surfaces comprises a non-woven substrate, preferably of cellulosic or cellulose-containing material, carrying an aqueous cleaning composition loaded onto the substrate at a level less than about 75%, preferably less than 50%, of its maximum absorbence capacity. The aqueous composition comprises one or more nonionic surfactants, one or more anionic surfactnats or a mixture of nonionic and anionic surfactants, a water miscible solvent for oils, (preferably a low molecular weight alcohol), 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.
Claims29
A disposable article for cleaning hard surfaces comprising, as non-woven substrate, a fibrous sheet consisting essentially of cellulosic material, rayon, polyolefins, polyester, nylon or mixtures thereof, and having a maximum absorbence capacity for water of at least 200 weight percent, said substrate being impregnated to a level not exceeding about 75% of its maximum absorbence capacity with an aqueous solution comprising
- from about 0.1 to about 1% by weight of at least one nonionic surfactant, at least one anionic surfactant, or a mixture of nonionic and anionic surfactants
- from about 0.2 to about 25% 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 from 8 to 12.
