What is claimed is:

1. An article, which comprises:
a. a carrier comprising a cellulosic fibrous structure having at least a first region of relatively high basis weight that comprises an essentially continuous network and a second region of a plurality of mutually discrete regions of relatively low basis weight which are circumscribed by the high basis weight first region; and
b. an emulsion applied to the carrier, the emulsion comprising:
(1) from 2 to 60% of a continuous, solidified lipid phase
comprising a waxy lipid material having a melting point of
30°C or higher;
(2) from 39 to 97% of an intemal 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.

2. The article of Claim 1 characterized in that the emulsion comprises from 5 to 30% lipid phase and from 67 to 92% polar phase; preferably from 6 to 15% lipid phase and from 82 to 91% polar phase.

3. The article of Claim 1 characterized in that the emulsion's intemal polar phase comprises at least 60% water; preferably at least 75% water.

4. The article of Claim 1 characterized in that the waxy lipid material has a melting point in the range of from 40° to 80°C; preferably in the range of from 60° to 70°C.

5. The article of Claim 1 characterized in that the waxy lipid material is selected from the group consisting of animal waxes, vegetable waxes, mineral waxes, synthetic waxes and mixtures thereof; preferably said waxy lipid material is selected from the group consisting of beeswax, carnauba, spermaceti, lanolin, shellac wax, candelilla, paraffin, petrolatum, microcrystalline wax, white ceresine wax, yellow ceresine wax, white ozokerite wax, polyethylene waxes, chlorinated naphthalenes, and mixtures thereof; more preferably the waxy lipid material is selected from the group consisting of beeswax, lanolin, candelilla, petrolatum, microcrystalline wax, yellow ceresine wax, white ozokerite, polyethylene waxes, and mixtures thereof.

6. The article of any of Claims 1-5 characterized in that the emulsion further comprises a component selected from the group consisting of perfumes, antimicrobials, detersive surfactants, pharmaceutical actives, deodorants, opacifiers, astringents, insect repellents, bleaches, radical scavengers, chelating agents, thickeners, builders, buffers, stabilizers, bleach activators, soil suspenders, dye transfer agents, brighteners, anti dusting agents, enzymes, dispersants, dye transfer inhibitors, pigments, dyes, and mixtures thereof; preferably the emulsion comprises a component selected from the group consisting of antimicrobials, detersive surfactants, bleaches, and mixtures thereof.

7. The article of any of Claims 1-6 characterized in that the aggregate surface area of the plurality of low basis weight regions of the cellulosic fibrous structure is at least 10% of the cellulosic fibrous structure's total surface area; preferably the aggregate surface area of the plurality of low basis weight regions is at least 20% of the cellulosic fibrous structure's total surface area; and further characterized in that the basis weight of the high basis weight region is at least 25% greater than the basis weight of the low basis weight regions; preferably at least 35% greater than the basis weight of the low basis weight regions; more preferably at least 50% greater than the basis weight of the low basis weight regions.

8. The article of any of Claims 1-7 characterized in that the carrier further comprises a third region comprising a plurality of mutually discrete regions having a basis weight intermediate to the high basis weight first region and the low basis weight second region, wherein each mutually discrete region having an intermediate basis weight is circumscribed by a discrete low basis weight region.

9. An article, which comprises:
a. a carrier comprising a cellulosic fibrous structure having at least a first region of relatively high basis weight that comprises an essentially continuous network and a second region of a plurality of mutually discrete regions of relatively low basis weight which are circumscribed by the high basis weight first region; and
b. an emulsion having a continuous external lipid phase and a dispersed polar intemal phase applied to the carrier, wherein further the emulsion is prepared by combining at least the following materials:
(1) from 2 to 60% of a waxy lipid material having a melting point
of30°C or higher;
(2) from 39 to 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.

10. The article of Claim 9 characterized in that the aggregate surface area of the plurality of low basis weight regions of the cellulosic fibrous structure is at least 10% of the cellulosic fibrous structure's total surface area; preferably the aggregate surface area of the plurality of low basis weight regions is at least 20% of the cellulosic fibrous structure's total surface area; and further characterized in that the basis weight of the high basis weight region is at least 25% greater than the basis weight of the low basis weight regions; preferably at least 35% greater than the basis weight of the low basis weight regions; more preferably at least 50% greater than the basis weight of the low basis weight regions.
