Abstract

A detergent composition comprising an enzyme and a bleaching compound and comprising two or more distinct regions, wherein the enzyme is located in a first distinct region and the bleaching compound is located in a second distinct region and further wherein a builder comprising an amino acid based compound and/or succinate based compound is located in the first distinct region. The compositions exhibit improved stability of the enzyme.

First claim

What is claimed is:

1. A detergent composition comprising an enzyme, a bleaching compound, and a builder, the detergent composition having three or more distinct regions, wherein at least two distinct regions are a solid and wherein at least one distinct region is a gel or paste,
wherein the enzyme is located in a first distinct region and the bleaching compound is located in a second distinct region and
wherein the builder comprises an amino acid based compound located in the first distinct region and in a third distinct region,
wherein the amino acid based compound comprises methyl-glycine-diacetic acid (MGDA), or salts thereof,
wherein the first distinct region is substantially free of bleaching compound,
wherein the second distinct region is substantially free of builder,
wherein the first distinct region is a solid, the second distinct region is a solid and the third distinct region is a gel or paste,
wherein the detergent composition is a unit dose detergent composition, and
wherein the first distinct region contacts the second distinct region.

2. The detergent composition according to claim 1 , wherein the enzyme comprises a protease.

3. The detergent composition according to claim 1 , wherein the bleaching compound is selected from inorganic peroxides or organic peracids and mixtures thereof.

4. The detergent composition according to claim 3 , wherein the inorganic peroxide is selected from the group consisting of percarbonates, perborates, persulphates and their salts.

5. The detergent composition according to claim 1 , wherein the first distinct region is free of bleaching compound.

6. The detergent composition according to claim 1 , wherein the second distinct region comprises 10% wt or less of the total amount of enzyme in the detergent composition.

7. The detergent composition according to claim 6 , wherein the second distinct region is substantially free of enzyme.

8. The detergent composition according to claim 6 , wherein the second distinct region is free of enzyme.

9. The detergent composition according to claim 1 , wherein the detergent composition is an automatic dishwashing composition.

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

11. A process of cleaning soiled items comprises contacting the soiled items with a detergent composition according to claim 1 .
