Abstract

An odor-controlling bodily fluid absorbent member comprises (a) an absorbent material or substrate; and (b) a halo active aromatic sulfonamide compound of Formula (I): wherein R 1 , R 2 , R 3 , R 4 , R 5 , X, M, and n are as described herein; and wherein at least one of R 1 , R 2 , R 3 , R 4 , and R 5 is not hydrogen. The absorbent member effectively controls odor arising from various body fluids.

Claims (38)

1. An odor-controlling bodily fluid absorbent member, consisting of:

an absorbent material; and dispersed therein

a first halo active aromatic sulfonamide compound of Formula (I):

wherein R 1 , R 2 , R 3 , R 4 , and R 5 are independently selected from hydrogen, COOH, COOM 1 , COOR′, CON(R″) 2 , alkoxy, CN, NO 2 , SO 3 R″, halogen, substituted or unsubstituted phenyl, sulfonamide, halosulfonamide, and substituted or unsubstituted C 1 -C 12 alkyl; M 1 is an alkali or alkaline earth metal; R′ is substituted or unsubstituted C 1 -C 12 alkyl; and R″ is hydrogen or substituted or unsubstituted C 1 -C 12 alkyl, and the two R″ groups in CON(R″) 2 may be independently selected;

wherein at least one of R 1 , R 2 , R 3 , R 4 , and R 5 is not hydrogen;

X is halogen;

M is an alkali or alkaline earth metal; and

n is the number of water molecules per molecule of the sulfonamide compound; and

a second different sulfonamide compound of Formula (I);

wherein a weight ratio of the first halo active aromatic sulfonamide compound to the second different sulfonamide compound is from 70:30 to about 90:10; and

a buffering agent;

wherein the two sulfonamide compounds are present in the range of from about 4 to about 7.5 weight percent, based on the weight of the absorbent member.

2. The absorbent member of claim 1 , wherein the absorbent material is a polymer, cellulosic fiber, or a wood fluff.

3. The absorbent member of claim 1 , wherein at least two of R 1 , R 2 , R 3 , R 4 , and R 5 are not hydrogen.

4. The absorbent member of claim 1 , wherein R 3 is methyl, COOH, COOM 1 , chlorine, fluorine, NO 2 , or methoxy.

5. The absorbent member of claim 1 , wherein R 3 is selected from COOH, COOM 1 , COOR′, CON(R″) 2 , CN, NO 2 , halogen, and substituted or unsubstituted C 2 -C 12 alkyl.

6. The absorbent member of claim 1 , wherein R 2 and R 4 are identical to each other; and R 1 , R 3 , and R 5 are hydrogen.

7. The absorbent member of claim 1 , wherein R 2 and R 4 are hydrogen; and R 1 , R 3 , and R 5 are identical to each other.

8. The absorbent member of claim 1 , wherein R 3 is selected from COOH, COOM 1 , COOR′, and CON(R″) 2 .

9. The absorbent member of claim 1 , wherein R 1 , R 2 , R 3 , R 4 , and R 5 are independently selected from hydrogen, COOH, COOM 1 , COOR′, CON(R″) 2 , NO 2 , halogen, and substituted or unsubstituted C 1 -C 12 alkyl.

10. The absorbent member of claim 1 , wherein R 3 is COOH or COOM 1 ; and R 1 , R 2 , R 4 , and R 5 are independently selected from hydrogen, NO 2 , halogen, and substituted or unsubstituted C 1 -C 12 alkyl.

11. The absorbent member of claim 1 , wherein the two compounds of Formula (I) are N-chloro-p-toluenesulfonamide and N-chloro-p-carboxysulfonamide.

12. The absorbent member of claim 1 , wherein one of the two sulfonamide compounds is of Formula (VI):

wherein M 2 is hydrogen, an alkali metal, or an alkaline earth metal.

13. The absorbent member of claim 1 , wherein the absorbent member is in the form of a flat sheet.

14. The absorbent member of claim 1 , wherein the absorbent member is used in a diaper, a sanitary napkin, a tampon, a wound dressing, or a bandage.

15. A diaper, sanitary napkin, tampon, wound dressing, or bandage comprising the absorbent member of claim 1 .

16. The absorbent member of claim 1 , wherein the absorbent material is wood fluff.

17. An odor-controlling bodily fluid absorbent member, consisting of:

an absorbent material; and dispersed therein

a first halo active aromatic sulfonamide compound which is N-chloro-p-carboxysulfonamide; and

a second halo active aromatic sulfonamide compound which is chloramine-T;

wherein a weight ratio of the first sulfonamide compound to the second sulfonamide compound is from about 70:30 to about 90:10; and

sodium bicarbonate;

wherein the first sulfonamide compound and the second sulfonamide compound are present in the range of from about 4 to about 7.5 weight percent, based on the weight of the absorbent member.

18. The absorbent member of claim 17 , wherein the absorbent material is a polymer, cellulosic fiber, or a wood fluff.

19. The absorbent member of claim 17 , wherein the absorbent member is in the form of a flat sheet.

20. The absorbent member of claim 17 , wherein the absorbent member is used in a diaper, a sanitary napkin, a tampon, a wound dressing, or a bandage.
