Abstract
Wet-like cleaning wipes and similar articles that are particularly useful in removing perianal soils. These wipes comprise a carrier comprising at least one polarphobic region, an optional, preferred substrate such as tissue paper web, and an emulsion applied to the carrier. The emulsion comprises a continuous external lipid phase and a dispersed internal polar phase. The continuous lipid phase of the emulsion is sufficiently brittle that it ruptures when subjected to low shear pressures during use to release the dispersed internal phase. Inclusion of the polarphobic region allows the ability to control flow of the internal water phase components following rupture of the emulsion.
