## Abstract

A granulate for a detergent composition, the granulate comprising a nitrogen-containing builder, wherein the granulate is at least partially coated with a coating material comprising an alkoxy polyalkylene glycol.

## Claims

### Claim 1

A granulate for a detergent composition, the granulate comprising a nitrogen-containing builder, wherein the granulate is at least partially coated with a coating material comprising an alkoxy polyalkylene glycol.

### Claim 2 (depends on 1)

The granulate according to claim 1, wherein the alkoxy group of the alkoxy polyalkylene glycol is represented by the formula RO wherein R is a C1 to C20 alkyl group.

### Claim 3 (depends on 1)

The granulate according to claim 1, wherein the polyalkylene glycol of the alkoxy polyalkylene glycol is selected from the group consisting of a polyethylene glycol, a polypropylene glycol, a polybutylene glycol, and combinations of two or more thereof.

### Claim 4 (depends on 1)

The granulate according to claim 1, wherein the alkoxy polyalkylene glycol is a methoxy polyethylene glycol.

### Claim 5 (depends on 1)

The granulate according to claim 1, wherein the alkoxy polyalkylene glycol has a weight average molecular weight of from 200 to 500 g/mol.

### Claim 6 (depends on 1)

The granulate according to claim 1, wherein the alkoxy polyalkylene glycol is a liquid at 25° C.

### Claim 7 (depends on 1)

The granulate according to claim 1, wherein the nitrogen-containing builder comprises an aminocarboxylate.

### Claim 8 (depends on 1)

The granulate according to claim 1, wherein the granulate and the coating material are present in a weight ratio of from 20:1 to 200:1

### Claim 9

A method of preparing a granulate for a detergent composition, the method comprising:
(i) providing particles comprising a nitrogen-containing builder; and
(ii) at least partially coating the particles with a coating material comprising an alkoxy polyalkylene glycol.

### Claim 10 (depends on 9)

The method according to claim 9, wherein the step of at least partially coating the particles with a coating material comprising an alkoxy polyalkylene glycol comprises spray-coating the particles with an alkoxy polyalkylene glycol in liquid form.

### Claim 11 (depends on 1)

A detergent composition comprising the granulate according to claim 1.

### Claim 12 (depends on 11)

The detergent composition according to claim 11, wherein the detergent composition is an automatic dishwashing composition or a laundry detergent composition.

### Claim 13 (depends on 11)

The detergent composition according to claim 11, wherein the composition further comprises a bleaching agent.

### Claim 14 (depends on 1)

The detergent composition according to claim 1, wherein the detergent composition is in the form of a solid.

### Claim 15 (depends on 1)

The detergent composition according to claim 1, wherein the nitrogen-containing builder is present in an amount of from 5 to 50 wt % by weight of the detergent composition, and/or
the detergent composition comprises a bleaching agent in an amount of from 1 to 50 wt % by weight of the detergent composition.

### Claim 16 (depends on 1)

The detergent composition according to claim 1, wherein the composition is storage stable for at least 12 weeks at 40° C. and 75% relative humidity.

### Claim 17 (depends on 11)

A detergent product comprising the detergent composition according to claim 11.

### Claim 18 (depends on 17)

The detergent product according to claim 17, wherein the product is:
in a unit dose form; and/or
housed within a water soluble or water dispersible film or container, preferably a polyvinyl alcohol film or container.

### Claim 19 (depends on 11)

A method of using a detergent composition according to claim 11 in an automatic dishwashing process or a laundry process.

### Claim 20

A method of using a coating material comprising an alkoxy polyalkylene glycol to reduce the yellowing of a nitrogen-containing builder in a detergent composition.
