Abstract

A personal care article can include a composition and a substrate. The article can be compliant to a surface.

First claim

What is claimed is:

1. A compliant personal cleansing article, comprising:
a) cleansing composition, comprising a rheology modifier and from about 10% to about 70%, by weight of the composition, of a synthetic surfactant; and
b) a water penetrable first substrate surrounding the composition; wherein the article has a compliance of about 1.50 kg/mm or less.

2. The compliant personal cleansing article of claim 1 , wherein the water penetrable substrate is a formed film.

3. The compliant personal cleansing article of claim 2 , wherein the formed film has a basis weight of about 10 g/m 2 to about 100 g/m 2 .

4. The compliant personal cleansing article of claim 1 , wherein the article has a compliance value after 2 simulated uses of about 0.01 kg/mm to about 1.5 kg/mm.

5. The compliant personal cleansing article of claim 1 , wherein the rheology modifier comprises clay, starch, a polymer, or a combination thereof.

6. The compliant personal cleansing article of claim 1 , wherein the composition has a consumption rate of about 3.5 to about 10 gm/use.

7. The compliant personal cleansing article of claim 1 , where the composition is about 4000 wt. % or more, by weight of the substrate.

8. The compliant personal cleansing article of claim 1 , wherein the article has a compliance of about 0.03 to about 1.5 kg/mm.

9. The compliant personal cleansing article of claim 1 , wherein the synthetic surfactant comprises a linear alkyl sulfate, a branched alkyl sulfate, linear alkyl ether sulfates, branched alkyl ether sulfates, linear alkyl sulfonates, branched alkyl sulfonates, linear alkyl ether sulfonates, branched alkyl ether sulfonates, or a combination thereof.

10. The compliant personal cleansing article of claim 1 , wherein the synthetic surfactant comprises an alkyl glucoside, alkyl polyglucoside, polyhydroxy fatty acid amide, alkoxylated fatty acid ester, sucrose ester, amine oxide, or mixtures thereof.

11. The compliant personal cleansing article of claim 1 , wherein the synthetic surfactant comprises sodium cocoyl isethionate.

12. The compliant personal cleansing article of claim 1 , wherein the cleansing composition has about 1 gram or more of the synthetic surfactant, by weight of the substrate.

13. The compliant personal cleansing article of claim 1 , wherein the cleansing composition has about 5 grams or more of the synthetic surfactant, by weight of the substrate.

14. The compliant personal cleansing article of claim 1 , wherein the cleansing composition further comprises an antibacterial agent.

15. The compliant personal cleansing article of claim 1 , wherein the antibacterial agent comprises zinc pyrithione.

16. The personal cleansing article of claim 1 , wherein the synthetic surfactant comprises isethionate, cocoamide monoethanolamine, cocoamidopropyl betaine, decyl glucoside, lauryl glucoside, an alkyl sufate, or a combination thereof.

17. The personal cleansing article of claim 1 , wherein the composition is a soft solid.

18. The personal cleansing article of claim 1 , wherein the water penetrable substrate surrounds the personal cleansing composition.

19. The personal care article of claim 1 , wherein the article is reusable.
