## Abstract

Compositions comprising oxidized soy polysaccharide compounds are disclosed herein. Oxidized soy polysaccharide compounds are produced by contacting soy polysaccharide under aqueous conditions with at least one N-oxoammonium salt, periodate compound, and/or peroxide compound.

## Claims

### Claim 1

A composition comprising an oxidized water soluble soy polysaccharide compound, wherein the compound is produced by contacting a water insoluble soy polysaccharide under aqueous conditions with:
(i) at least one N-oxoammonium salt,
(ii) at least one periodate compound, and/or
(iii) at least one peroxide compound;
wherein the water insoluble soy polysaccharide comprises arabinose, galactose, xylose, and galacturonic acid as a majority of constituent monosaccharide monomeric units.

### Claim 2 (depends on 1)

The composition of claim 1, wherein the soy polysaccharide is contacted with the N-oxoammonium salt.

### Claim 3 (depends on 1)

The composition of claim 1, wherein the soy polysaccharide is first contacted with the periodate compound, and then contacted with the N-oxoammonium salt.

### Claim 4 (depends on 1)

The composition of claim 1, wherein the N-oxoammonium salt comprises a TEMPO oxoammonium salt.

### Claim 5 (depends on 1)

The composition of claim 1, wherein the composition is a household product, personal care product, industrial product, pharmaceutical product, or food product.

### Claim 6 (depends on 5)

The composition of claim 5, wherein the household product is a detergent composition.

### Claim 7

A method of producing an oxidized water soluble soy polysaccharide compound, the method comprising:
(a) contacting a water insoluble soy polysaccharide under aqueous conditions in sequence first with at least one periodate compound followed by at least one N-oxoammonium salt,
wherein the water insoluble soy polysaccharide is oxidized by the N-oxoammonium salt and periodate compound thereby producing an oxidized water soluble soy polysaccharide compound, and
(b) optionally, isolating the oxidized water soluble soy polysaccharide compound.

### Claim 8 (depends on 7)

The method of claim 7, wherein the N-oxoammonium salt comprises a TEMPO oxoammonium salt.

### Claim 9 (depends on 8)

The method of claim 8, wherein the N-oxoammonium salt comprises a 4-acetamido-TEMPO oxoammonium salt.

### Claim 10 (depends on 8)

The method of claim 8, wherein the TEMPO oxoammonium salt is provided by oxidizing an agent comprising TEMPO under said aqueous conditions.

### Claim 11 (depends on 7)

The method of claim 7, wherein the aqueous conditions are acidic or basic.

### Claim 12 (depends on 7)

A method of increasing the builder capacity and/or anti-redeposition capacity of an aqueous composition, wherein the method comprises:
contacting an oxidized soy polysaccharide compound produced according to the method of claim 7 with an aqueous composition, wherein the builder and/or anti-redeposition capacity of the aqueous composition is increased by the oxidized soy polysaccharide compound compared to the builder and/or anti-redeposition capacity of the aqueous composition before the contacting step.

### Claim 13 (depends on 7)

A method of treating a material, said method comprising:
contacting a material with an aqueous composition comprising an oxidized soy polysaccharide compound produced according to the method of claim 7.
