Abstract
Abstract A disposable impregnated wiper for treatment of household surfaces such as furniture. The wiper comprises a cellulosic substrate having a bonding material impregnated into at least one surface in a fine pattern to form bonded web portions of greater strength than the adjacent portions, such substrate being substantially compressible, and an oil-in-water emulsion impregnant having an internal phase of mineral oil and silicone fluid in specified amounts and ratios. The impregnant composition and substrate are in specified ratios and the substrate is loaded to no more than about 50% of its liquid capacity.
