## Abstract

Antimicrobial and odor control animal-related material compositions used to form animal litter or bedding include a base material and a halo active aromatic sulfonamide compound of Formula (I): wherein the variables R1, R2, R3, R4, R5, X, and M are disclosed herein. The resulting animal litter or bedding maintain antimicrobial and odor-controlling properties over extended time periods.

wherein R3 is COOH, COOM1, COOR′, or CON(R″)2;
wherein R′ is hydrogen, an alkali metal, an alkaline earth metal, substituted C1-C18 alkyl, or unsubstituted C1-C18 alkyl; and
wherein R″ is hydrogen or substituted or unsubstituted C1-C18 alkyl, where the two R″ groups in CON(R″)2 and N(R″)2 may be independently selected from each other;
X is halogen; and

### Claim 5 (depends on 1)

The animal litter of claim 1, wherein the halo active aromatic sulfonamide compound is in the form of a powder having an average particle size of 50 micrometers (μm) or less.

### Claim 6 (depends on 1)

The animal litter of claim 1, wherein the animal litter further comprises from about 0.01 wt % to about 20 wt % of an additional additive.

### Claim 7 (depends on 6)

The animal litter of claim 6, wherein the additional additive is an acrylic, a latex, a polyvinyl acetate, a cellulose, a surfactant, an alcohol, a pH stabilizer, a thickener, a sealer, a cleaner, a pigment, or a water-retentive additive.

### Claim 8

A method for treating animal waste, comprising:
providing a container containing an animal litter;
permitting an animal to excrete waste into the animal litter;
wherein the animal litter comprises an absorbent base material and a halo active aromatic sulfonamide compound of Formula (I):
wherein R1, R2, R4, and R5 are independently selected from hydrogen, COOR′, CON(R″)2, alkoxy, CN, NO2, SO3R″, halogen, substituted or unsubstituted phenyl, sulfonamide, halosulfonamide, N(R″)2, substituted or unsubstituted C1-C18 alkyl, and substituted or unsubstituted aromatic; and
wherein R3 is COOH, COOM1, COOR′, or CON(R″)2;
wherein R′ is hydrogen, an alkali metal, an alkaline earth metal, substituted C1-C18 alkyl, or unsubstituted C1-C18 alkyl; and
wherein R″ is hydrogen or substituted or unsubstituted C1-C18 alkyl, where the two R″ groups in CON(R″)2 and N(R″)2 may be independently selected from each other;
X is halogen; and
M and M1 are independently an alkali or alkaline earth metal.

### Claim 9 (depends on 8)

The method of claim 8, wherein the halo active aromatic sulfonamide compound is N-chloro-4-carboxybenzenesulfonamide.

### Claim 10 (depends on 8)

The method of claim 8, wherein the animal litter comprises from about 0.01 wt % to about 20 wt % of the halo active aromatic sulfonamide compound.

### Claim 11 (depends on 8)

The method of claim 8, wherein the absorbent base material has an average particle size of 100 micrometers (μm) to about 2000 μm, and the halo active aromatic sulfonamide compound is in the form of a powder having an average particle size of 50 micrometers (μm) or less.

### Claim 12
