Abstract

The invention relates to detergent compositions comprising granular non-phosphate builder. The granules comprise an amino acid based builder, preferably MGDA, and s silicate. The composition is housed in a rigid PVOH capsule.

Claims

1. An ADW detergent composition comprising at least one granule, the at least one granule comprising an amino acid based builder and a silicate and wherein the composition is a mono-dose detergent composition housed within a rigid PVOH capsule with one or more compartments.

2. The composition according to claim 1, wherein the at least one granule comprises at least 50% by weight of the amino acid based builder.

3. The composition according to claim 2, wherein the amino acid based builder is MGDA.

4. The composition according to claim 1, wherein the silicate comprises at least 0.5% by weight of the granule.

5. The composition according to claim 1, wherein the granule contains further optional ingredients.

6. The composition according to claim 1, wherein the rigid PVOH capsule is selected from the group consisting of a thermoformed structure, a vacuum formed structure, an injection moulded structure, and a combination thereof.

7. The detergent composition according to claim 1, wherein the at least one granule comprises:

MGDA 50-90% by weight;

silicate 5-30% by weight; and

optional ingredients 0-15% by weight.

8. The composition according to claim 1, wherein the at least one granule has a diameter of 0.01 to 5 mm.

9. The composition according to any claim 1, wherein the composition comprises a plurality of granules.

10. The use of the detergent composition according to claim 1 to treat soiled tableware in an automatic dishwashing machine.

11. The composition according to claim 1, wherein the silicate comprises at least 1.0% by weight of the granule.

12. The composition according to claim 1, wherein the silicate comprises at least 1.5% by weight of the granule.

13. An automatic dishwashing (ADW) detergent composition comprising a plurality of granules, at least a portion of the granules each comprising an amino acid based builder and a silicate, wherein the ADW detergent composition is a mono-dose detergent composition housed within a rigid polyvinyl alcohol (PVOH) capsule with one or more compartments.

14. The composition according to claim 13, wherein at least a portion of the granules each comprise at least 50% by weight of methylglycinediacetic acid (MGDA).

15. The composition according to claim 13, wherein at least a portion of the granules each comprise at least 1.5% by weight of silicate.

16. The composition according to claim 13, wherein the rigid PVOH capsule is selected from the group consisting of a thermoformed structure, a vacuum formed structure, an injection molded structure, and a combination thereof.

17. The detergent composition according to claim 13, wherein at least a portion of the granules each comprise:

MGDA 50-90% by weight; and

silicate 5-30% by weight.

18. The composition according to claim 13, wherein at least a portion of the granules each have a diameter of 0.01 to 5 mm.
