Abstract

Wet-like cleaning wipes and similar articles that are particularly useful in removing perianal soils. These wipes comprise a carrier substrate such as tissue paper web and a emulsion applied to the substrate, wherein the emulsion comprises a continuous external lipid phase and a dispersed internal polar phase (e.g., water). The continuous external lipid phase of this emulsion is sufficiently brittle that it ruptures when subjected to low shear during use to release the dispersed internal polar phase.
