1. An article, which comprises:
- a. a carrier; and
b. an emulsion applied to the carrier, the emulsion comprising;
(1) from about 2 to about 60% of a continuous, solidified lipid phase comprising a waxy lipid material having a melting point of about 30°
C. or higher;
(2) from about 39 to about 97% of an internal polar phase dispersed in the lipid phase; and
(3) an effective amount of an emulsifier capable of forming the emulsion when the lipid phase is in a fluid state;
c. wherein the article has a rate of absorbency of distilled water of not more than about 0.35 gram per gram of carrier per second.

Abstract
Wet-like cleaning wipes and similar articles are described. These wipes comprise a carrier that provides controlled fluid absorbency and an emulsion applied to the carrier. The emulsion comprises a continuous external lipid phase and a polar (e.g., water) internal phase. The emulsion is sufficiently brittle that it ruptures when subjected to low shear pressures during use to release the dispersed polar phase. The carrier allows the released internal phase to initially reach and remain on the surface being cleaned, but then absorbs the material at the end of the wiping process.

21. An article, which comprises:
-
a. a carrier; and b. an emulsion applied to the carrier, the emulsion comprising; (1) from about 5 to about 30% of a continuous, solidified lipid phase comprising a waxy lipid material having a melting point of from about 40°

23. An article, which comprises:
-
a. a carrier; and b. an emulsion having a continuous external lipid phase and a dispersed polar internal phase applied to the carrier; wherein the article has a rate of absorbency of distilled water of not more than about 0.35 gram per gram of carrier per second, and wherein further the emulsion is prepared by combining at least the following materials; (1) from about 2 to about 60% of a waxy lipid material having a melting point of about 30°
C. or higher;(2) from about 39 to about 97% of a polar material; and (3) an effective amount of an emulsifier capable of forming the emulsion when the waxy lipid is in a fluid state; where the weight percent for each of components (1), (2) and (3) is determined from the amount combined relative to the total weight of the emulsion.
