Abstract
A wipe comprising a high internal phase inverse emulsion disposed in a discontinuous pattern on a substrate. The pattern provides areas coated with the emulsion and areas free of the emulsion. Preferably the emulsion is disposed so that the surface area to volume ratio of the emulsion is minimized. The emulsion locally expresses water during use upon the application of pressure to the wipe. The water is useful for cleaning. The discontinuous pattern of the emulsion provides regions of the substrate which are wetted during use and regions which may remain dry. The wetted regions transfer water to the surface to be cleaned. The dry regions then remove the water from the surface for more efficacious cleaning.
