Abstract

A disposable article adapted to receive bodily exudates which provides improved management of such bodily exudates by including an effective amount of one or more agents which act to modify the physical properties of feces or other bodily wastes which may be deposited in the article, or by including one or more compositions such as the aforesaid one or more agents which enhance the removability of bodily waste, such as feces, from the skin of the article's wearer.

Claims (23)

1. An absorbent article having a first waist region, a second waist region opposed to the first waist region, a crotch region disposed between the first waist region and the second waist region, the absorbent article comprising:

a topsheet;

a backsheet joined to at least a portion of the topsheet;

an absorbent core disposed between at least a portion of the topsheet and the backsheet, and

a three-dimensional structure comprising protrusions, the three-dimensional structure joined to the topsheet such that the topsheet is disposed between the three-dimensional structure and the absorbent core, the protrusions comprising an effective amount of a feces modifying agent, wherein the protrusions promote contact between the feces modifying agent and feces.

2. The absorbent article of claim 1 wherein the feces modifying agent is a viscosity decreasing agent.

3. The absorbent article of claim 1 wherein the feces modifying agent is a feces water-liberating agent.

4. The absorbent article of claim 3 wherein the feces water liberating agent is a flocculant.

5. The absorbent article of claim 3 wherein the feces water liberating agent includes an inorganic flocculant.

6. The absorbent article of claim 5 wherein the inorganic flocculant is selected from the group including divalent and trivalent metal salts.

7. The absorbent article of claim 6 wherein the metal salts are selected from the group consisting of: iron, aluminum, calcium, and sodium salts and mixtures thereof.

8. The absorbent article of claim 6 wherein the metal salts are selected from the group consisting of: ferrous chloride, ferric chloride, aluminum potassium sulfate, aluminum sulfate, sodium aluminate, ferrous sulfate, aluminum chloride hydroxide, and poly aluminum silicate sulfate.

9. The absorbent article of claim 3 wherein the feces water liberating agent includes an organic flocculant.

10. The absorbent article of claim 9 wherein the organic flocculant is selected from the group consisting of: water soluble polyamides and derivatives, polyacrylics and derivatives, polyamines, and polyvinylpyrollidone.

11. The absorbent article of claim 1 wherein the feces modifying agent includes a viscosity increasing agent.

12. The absorbent article of claim 11 wherein the viscosity increasing agent includes a thickener.

13. The absorbent article of claim 12 wherein the thickener is selected from the group including: carboxymethyl cellulose, xanthan gum, polyacrylic acid and salts thereof, polyacrylamide, and polyethyleneimines.

14. The absorbent article of claim 11 wherein the viscosity increasing agent includes an ionic complexing agent.

15. The absorbent article of claim 14 wherein the ionic complexing agent is selected from the group consisting of: ZnO, MgO, MnO, CaO, calcium hydroxide, ethanolamines, quaternary ammonium salts, and Al2O3, alginates, zinc salts, aluminum salts and combinations thereof.

16. The absorbent article of claim 14 wherein the ionic complexing agent includes a crosslinking agent.

17. The absorbent article of claim 1 wherein the feces modifying agent reduces the Hardness of the feces by at least about 25% at a concentration of no more than about 0.5 weight percent.

18. The absorbent article of claim 1 wherein the feces modifying agent increases the Hardness of the feces by greater than or equal to about 100% at a concentration of no more than about 0.5 weight percent.

19. The absorbent article of claim 1 wherein the feces modifying agent is present in concentration of greater than or equal to about 0.01% by weight of the article.
