Abstract

The present invention relates to a substantially dry article containing an insoluble substrate, at least one oxidizing agent, and at least one reducing agent, wherein the article is exothermic when wet with water and the use thereof.

Claims

1. A substantially dry article comprising an insoluble substrate, at least one oxidizing agent, and at least one reducing agent, wherein said article is exothermic when wet with water.

3. The article of claim 1 wherein said at least one oxidizing agents comprises at least one compound selected from the group consisting of sodium perborate monohydrate, ammonium persulfate, sodium persulfate, potassium persulfate, sodium carbonate peroxide, calcium peroxide, magnesium peroxide, and carbamide peroxide.

4. The article of claim 1 wherein said at least one reducing agent comprises at least one compound selected from the group consisting of sodium thiosulfate, thiourea, sodium sulfite, sodium bisulfite, sodium metabisulfite, sodium borohydride, and sodium hypophosphite.

5. The article of claim 3 wherein said at least one reducing agent comprises at least one compound selected from the group consisting of sodium thiosulfate, thiourea, sodium sulfite, sodium bisulfite, sodium metabisulfite, sodium borohydride, and sodium hypophosphite.

6. The article of claim 1 wherein the equivalent ratio of said at least one oxidizing agent to said at least one reducing agent ranges from 1:

20 to 20;

1.

7. The article of claim 1 wherein following being wet with water, a surface of said article becomes heated to from about 30°

C. to about 50°

C.

8. The article of claim 1 further comprising a lathering surfactant.

9. The article of claim 1 further comprising a water-soluble polymer in contact with said at least one oxidizing agent, said at least one reducing agent, or both said at least one oxidizing agent and said at least one reducing agent.

10. The article of claim 9 wherein said water-soluble polymer is selected from the group consisting of polyethylene glycol, polyethylene oxide, polyvinyl alcohol, cellulose ethers, copolymers of vinyl pyrrolidone and vinyl acetate, and mixtures thereof.

11. A method of heating the skin, nail, or hair, said method comprising applying to said skin, nail, or hair an article of claim 1, wherein said article is wet with water prior to, during, or after said application.

12. The method of claim 11, wherein said substrate comprises a nonwoven sheet.

13. The method of claim 11, wherein said substrate is absorbent.

14. The method of claim 11 wherein said at least one oxidizing agents comprises at least one compound selected from the group consisting of sodium perborate monohydrate, ammonium persulfate, sodium persulfate, potassium persulfate, sodium carbonate peroxide, calcium peroxide, magnesium peroxide, and carbamide peroxide.

15. The method of claim 11 wherein said at least one reducing agent comprises at least one compound selected from the group consisting of sodium thiosulfate, thiourea, sodium sulfite, sodium bisulfite, sodium metabisulfite, sodium borohydride, and sodium hypophosphite.

16. The method of claim 14 wherein said at least one reducing agent comprises at least one compound selected from the group consisting of sodium thiosulfate, thiourea, sodium sulfite, sodium bisulfite, sodium metabisulfite, sodium borohydride, and sodium hypophosphite.

17. The method of claim 11 wherein the equivalent ratio of said at least one oxidizing agent to said at least one reducing agent ranges from 1:

20 to 20;

1.

18. The method of claim 11 wherein following being wet with water, a surface of said article becomes heated to from about 30°

C. to about 50°

C.

19. The method of claim 11 further comprising a water-soluble polymer in contact with said at least one oxidizing agent, said at least one reducing agent, or both said at least one oxidizing agent and said at least one reducing agent.

20. The method of claim 19 wherein said water-soluble polymer is selected from the group consisting of polyethylene glycol, polyethylene oxide, polyvinyl alcohol, cellulose ethers, copolymers of vinyl pyrrolidone and vinyl acetate, and mixtures thereof.

2. The article of claim 2, wherein said substrate comprises a nonwoven sheet.

21. A method of cleansing the skin, nail, or hair, said method comprising wetting an article with water prior to, during, or after application of said article to said skin, nail, or hair, wherein said article is a substantially dry article comprising an insoluble substrate, at least one oxidizing agent, at least one reducing agent, and a lathering surfactant, wherein said article is exothermic when wet with water.

22. The method of claim 21, wherein said substrate comprises a nonwoven sheet.

23. The method of claim 21, wherein said lathering surfactant is an anionic surfactant.

24. The method of claim 21 wherein said at least one oxidizing agent comprises at least one compound selected from the group consisting of sodium perborate monohydrate, ammonium persulfate, sodium persulfate, potassium persulfate, sodium carbonate peroxide, calcium peroxide, magnesium peroxide, and carbamide peroxide.

25. The method of claim 21 wherein said at least one reducing agent comprises a compound selected from the group consisting of sodium thiosulfate, thiourea, sodium sulfite, sodium bisulfite, sodium metabisulfite, sodium borohydride, and sodium hypophosphite.

26. The method of claim 24 wherein said at least one reducing agent comprises a compound selected from the group consisting of sodium thiosulfate, thiourea, sodium sulfite, sodium bisulfite, sodium metabisulfite, sodium borohydride, and sodium hypophosphite.

27. The method of claim 21 wherein the equivalent ratio of said at least one oxidizing agent to said at least one reducing agent ranges from 1:

20 to 20;

1.

28. The method of claim 21 wherein following being wet with water, a surface of said article becomes heated to from about 30°

C. to about 50°

C.

29. The method of claim 21 further comprising a water-soluble polymer in contact with said at least one oxidizing agent, said at least one reducing agent, or both said at least one oxidizing agent and said at least one reducing agent.

30. The method of claim 29 wherein said water-soluble polymer is selected from the group consisting of polyethylene glycol, polyethylene oxide, polyvinyl alcohol, cellulose ethers, copolymers of vinyl pyrrolidone and vinyl acetate, and mixtures thereof.
