1. An article, which comprises:
- a. a carrier comprising at least one polarphobic region; and
b. an emulsion applied to the carrier, the emulsion comprising;
(1) from about 2 to about 60% of a continuous solidified external lipid phase comprising a waxy lipid material having a melting point of about 40°
C. or higher,(2) from about 39 to about 97% of an internal polar phase dispersed in the external lipid phase; and
(3) an effective amount of an emulsifier capable of forming the emulsion when the external lipid phase is in a fluid state.

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.

26. An article, which comprises:
-
a. a carrier comprising at least one polarphobic region; and b. an emulsion having a continuous external lipid phase and a dispersed polar internal phase applied to the carrier;
wherein the emulsion is prepared by combining at least the following materials;(1) from about 2 to about 60% of a a waxy lipid material having a melting point of about 40°
