Abstract

The present invention relates to disposable, personal cleansing articles useful for cleansing the skin or hair. These articles are used by the consumer by wetting the dry article with water and then rubbing the article against the skin or hair. The article comprises a water insoluble substrate having a cleansing surface that contains apertures of a certain size and frequency, and a lathering surfactant releasably associated with the substrate. Preferably, the articles of the present invention further comprise a conditioning component.

Claims

1. A disposable, single use, personal cleansing article for cleansing and conditioning the skin, said personal cleansing article being water-activated during use to generate lather, said article comprising:

(b) from about 0.5% to about 250% by weight of said substrate of a lathering surfactant releasably associated with said substrate; and

(c) from 0.01% to about 99% by weight of said substrate of a conditioning component added onto or impregnated into said substrate, wherein said conditioning component comprises petrolatum;

wherein the substrate is a nonwoven substrate comprised of fibers.

2. The article of claim 1 wherein said article is substantially dry.

10. The article of claim 5 wherein the apertures are located within said cleansing surface of said substrate at a frequency of from about 3 to about 6 per linear centimeter.

11. The article of claim 5 wherein the apertures are uniformly distributed within said cleansing surface of said substrate.

12. The article of claim 5 wherein the conditioning component is present at a level ranging from 0.1% to 50% by weight of the substrate.

13. The article of claim 12 wherein the conditioning component is present at a level ranging from 1% to 25% by weight of the substrate.

14. The article of claim 5 wherein the conditioning component comprises an oil soluble conditioning component and a water soluble conditioning component wherein the oil soluble conditioning component comprises petrolatum and wherein the water soluble conditioning component comprises glycerin.

15. The article of claim 5 which additionally comprises cationic polymer at a level ranging from about 0.1% to about 1% by weight of the substrate.

16. The article of claim 5 wherein the apertures protrude completely through the substrate to the surface of the substrate which is opposite to the cleansing surface.

17. The article of claim 5 wherein the conditioning component comprises an oil soluble conditioning component which consists essentially of petrolatum.

18. The article of claim 17 wherein the conditioning component additionally comprises a water soluble conditioning component.

19. The article of claim 18 wherein the water soluble conditioning component comprises glycerin.

20. The article of claim 5 wherein the nonwoven substrate consists essentially of fibers.

21. The article of claim 1 wherein the nonwoven substrate has a basis weight of from about 24 to about 96 gsm.

22. The article of claim 21 wherein the nonwoven substrate has a basis weight of from about 36 to about 84 gsm.

23. The article of claim 22 wherein the nonwoven substrate has a basis weight of from about 42 to about 78 gsm.
