Disposable semi-moist wipes
First Claim
1. 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 comprisingfrom 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 surfactantsfrom about 0.2 to about 25% by weight of a water miscible solvent for oils, andammonium 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.

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.
