Abstract

Multi-use personal care compositions and articles can include a surfactant, a water insoluble hygroscopic fine, fiber, or filament, and a preservative, where such compositions and articles can show an improved preservative property versus unpreserved compositions.

First claim

What is claimed is:

1. A multi-use personal cleansing article, comprising:
a) from about 40% to about 99.6%, by weight of the article, of a soft solid cleansing composition, comprising;
i) from about 20% to about 80%, by weight of the composition, of a surfactant comprising cocoamide monoethanolamine, cocoamidopropyl betaine, decyl glucoside, lauryl glucoside, an alkyl sulfate, an alkyl sulfonate, or a combination thereof;
ii) from about 3% to about 40%, by weight of the composition, of a fine, fiber, or filament, comprising cellulose;
iii) a solvent;
iv) a first preservative comprising an organic acid, citric acid, salicylic acid, sorbic acid, zinc pyrithione, or a combination thereof; and
v) a second preservative comprising methylisothiazolinone, sodium benzoate, or a combination thereof; and

b) a water insoluble substrate at least partially surrounding the composition;
wherein the article has a compliance value of about 0.1 kg/mm to about 1.5 kg/mm after two simulated uses and a consumption rate of 1.0 to about 10.0 g/use; and the composition has a water activity of about 0.90 or more after two simulated uses.

2. The multi-use personal cleansing article of claim 1 , wherein the water insoluble substrate comprises a multiplanar film.

3. The multi-use personal cleansing article of claim 1 , wherein the water insoluble substrate comprises a multiplanar vacuum formed film.

4. The multi-use personal cleansing article of claim 1 , wherein the first preservative comprising zinc pyrithione.

5. The multi-use personal cleansing article of claim 1 , wherein the composition has a compliance value of about 0.10 kg/mm to about 0.3 kg/mm before a simulated use.

6. The multi-use personal cleansing article of claim 1 , wherein the composition comprises the filament which comprises fibers and fines and the fibers have an aspect ratio of about 9 to about 1,000.

7. The multi-use personal cleansing article of claim 1 , wherein the composition has a compliance value of 0.01 mm/kg to about 1.5 mm/kg after 48 hours of drying after one simulated use.

8. The multi-use personal cleansing article of claim 1 , wherein the water insoluble substrate surrounds the composition.

9. The multi-use personal cleansing article of claim 1 , wherein the substrate is water penetrable.

10. The multi-use personal cleansing article of claim 9 , wherein a second substrate is adjacent to the water insoluble substrate.

11. The multi-use personal cleansing article of claim 10 , wherein the second substrate is water penetrable.

12. The multi-use personal cleansing article of claim 9 , wherein the cellulose derives from a plant.

13. The multi-use personal cleansing article of claim 12 , wherein the composition comprises from about 15% to about 25%, by weight of the composition, of the cellulose.
