Abstract

A personal care article is disclosed having a first compliant personal care composition in a first zone and a second compliant personal care composition in a second zone such that the first and second zones are defined by one or more barriers. Methods for increasing lather are also disclosed herein.

First claim

What is claimed is:

1. A personal care article, comprising:
a) a first compliant personal care composition in a first zone;
b) a second compliant personal care composition in a second zone, wherein each of the zones is defined by one or more barriers; and
c) a first water penetrable substrate adjacent to the first and second compliant personal care compositions;

wherein a total compliant personal care composition is greater than about 3,500 wt. %, by weight of a total substrate;
wherein the first and second compliant personal care compositions are configured to be released at each zone;
wherein the first compliant personal care composition is the same as the second compliant personal care composition;
wherein the personal care article comprises a top side and a bottom side, wherein the first zone can be located at one of either the top side or the bottom side and the second zone can be located at the remaining side;
wherein the personal care article comprises a right side and a left side, wherein the first zone can be located at one of either the right side or the left side and the second zone can be located at the remaining side;
wherein at least one of the one or more barriers is selected from the group consisting of a batting, a formed film, a polyurethane sponge, a scrim, a seal, a second water penetrable substrate and combinations thereof;
wherein at least one of the one or more barriers is substantially impermeable;
wherein each of the first and second compliant personal care compositions has a compliance value of about 1.5 kg/mm or less.

2. The personal care article of claim 1 ,
wherein the first water penetrable substrate at least partially surrounds each of the first and second compliant personal care composition; and
comprising a second water penetrable substrate adjacent to and in contact with the first water penetrable substrate,
wherein the second water penetrable substrate at least partially surrounds the first water penetrable substrate; and
wherein the second water penetrable substrate at least partially surrounds the first water penetrable substrate; and
wherein the article has a consumption rate of about ⅕ g/use to about 15 g/use.

3. A personal care article, comprising:
a) about 4,000 wt. % or more, by weight of a total substrate, of a total compliant personal care composition, wherein said first compliant personal care composition is in a first zone, wherein a second compliant personal care composition is in a second zone, wherein each of the zones is defined by one or more barriers, and wherein the first and second compliant personal care compositions are configured to be released at each zone; and
b) a first substrate surrounding the first and second compliant personal care compositions and having a water flux rate of about 0.1 cm 3 /cm 2 /s to about 60 cm 3 /cm 2 /s, and
c) a second substrate surrounding the first substrate and having a water flux rate of about 0.1 cm 3 /cm 2 /s to about 60 cm 3 /cm 2 /s; and

wherein one of the first zone and the second zone is a cleansing phase and the other is a benefit phase, and
wherein said article has a consumption rate of about 0.05 g/use to about 20 g/use.

4. The personal care article of claim 3 , wherein each of the first and second compliant personal care compositions has a compliance value of about 1.5 kg/mm or less.
