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 cleansing composition in a first zone;
b) a second compliant cleansing 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 cleansing compositions;
wherein a total compliant cleansing composition is greater than about 3,500 wt. %, by weight of a total substrate; wherein each of the first and second compliant cleansing compositions has a compliance value of about 1.5 kg/mm or less.

2. The personal care article of claim 1 , wherein the first and second compliant cleansing compositions are configured to be released at each zone.

3. The personal care article of claim 1 , wherein the first compliant cleansing composition is the same as the second compliant cleansing composition.

4. The personal care article of claim 1 , 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.

5. The personal care article of claim 1 , 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.

6. The personal care article of claim 1 , 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.

7. The personal care article of claim 6 , wherein at least one of the one or more barriers is substantially impermeable.

8. The personal care article of claim 1 , wherein the first water penetrable substrate at least partially surrounds each of the first and second compliant cleansing compositions.

9. The personal care article of claim 1 , further comprising a second water penetrable substrate adjacent to and in contact with the first water penetrable substrate.

10. The personal care article of claim 9 , wherein the second water penetrable substrate at least partially surrounds the first water penetrable substrate.

11. The personal care article of claim 1 , wherein the article has a consumption rate of about 1.5 g/use to about 15 g/use.

12. The personal care article of claim 1 , wherein the first water penetrable substrate has a water flux rate of about 20 cm 3 /cm 2 /s or more.

13. The personal care article of claim 1 , wherein the total compliant cleansing composition is greater than about 4,000 wt. %, by weight of the total substrate.

14. 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 a compliant cleansing composition is in a first zone, wherein a compliant personal care composition is in a second zone, wherein each of the zones is defined by one or more barriers, and wherein the compliant cleansing composition and the compliant personal care composition are configured to be released at each zone; and
b) a first substrate surrounding the compliant cleansing composition and the compliant personal care composition 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; wherein each of the cleansing composition and the personal care composition has a compliance value of about 1.5 kg/mm or less.

15. The personal care article of claim 14 , wherein one of the the personal care composition comprises a benefit phase.

16. The personal care article of claim 14 has a consumption rate of about 0.05 g/use to about 20 g/use.

17. The personal care article of claim 14 , wherein the total compliant cleansing composition and personal care composition is greater than about 5,000 wt. %, by weight of the total substrate.
