Abstract

A package for an automatic dishwashing cycle, the package comprising at least one detergent composition in the form of a solid and at least one detergent composition in the form of a gel, wherein the weight ratio of the total amount of solid detergent composition to the total amount of gel detergent composition is between about 1.60:1 and about 3.00:1.

First claim

The invention claimed is:

1. A package for an automatic dishwashing cycle, the package comprising:
at least one detergent composition in the form of a solid, wherein the solid detergent composition comprises at least about 20 wt % of at least one builder based on a total weight of the solid detergent composition, at least about 10 wt % of at least one bleaching agent based on the total weight of the solid detergent composition, and at least one enzyme; and
at least one detergent composition in the form of a gel, wherein the gel detergent composition comprises at least about 25 wt % of at least one builder based on a total weight of the gel detergent composition; and
wherein the weight ratio of the total amount of solid detergent composition to the total amount of gel detergent composition is between 2.00:1 and 3.00:1.

2. The package according to claim 1 , wherein the package is a multi-compartment package comprising two or more separated compartments.

3. The package according to claim 2 , wherein the multi-compartment package comprises at least a first compartment and a second compartment, further wherein the at least one solid detergent composition is located within the first compartment and the at least one gel detergent composition is located within the second compartment.

4. The package according to claim 3 , wherein the multi-compartment package further comprises at least one detergent composition in the form of a liquid.

5. The package according to claim 4 , wherein the multi-compartment package further comprises a third compartment, wherein the at least one liquid detergent composition is located within the third compartment.

6. The package according to claim 1 , wherein the weight ratio of the total amount of the solid detergent composition to the total amount of the gel detergent composition plus the total amount of the liquid detergent composition is between 1.70:1.00 and 3.00:1.00.

7. The package according to claim 1 , wherein the at least one solid detergent composition is present in an amount of at least 56 wt. %, based on the total weight of the package.

8. The package according to claim 1 , wherein the at least one gel detergent composition is present in an amount of no more than 36 wt. %, based on the total weight of the package.

9. The package according to claim 4 , wherein the at least one liquid detergent composition is present in an amount of no more than 3.4 wt. %, based on the total weight of the package.

10. The package according to claim 1 , wherein the package is a water-soluble package.

11. The package according to claim 10 , wherein the water-soluble package comprises or is a poly(vinyl alcohol).

12. The package according to claim 11 , wherein the water-soluble package comprises a thermoformed poly(vinyl alcohol) film.

13. The package according to claim 10 , wherein the water-soluble package is formed of a water-soluble film.

14. The package according to claim 13 , wherein the water-soluble film is rigid or flexible at room temperature.

15. The package according to claim 1 , wherein the package is in a unit-dose format.

16. A method of washing soiled kitchenware comprising contacting the kitchenware with the package according to claim 1 .

17. A method of treating or washing kitchenware in an automatic dishwashing machine, wherein the package according to claim 1 is added to the automatic dishwashing machine.

18. The method of treating or washing kitchenware in an automatic dishwashing machine according to claim 17 , wherein the package is added to the automatic dishwashing machine at the start of a main wash cycle or at the start of a pre-wash cycle.

19. The method of treating or washing kitchenware in an automatic dishwashing machine according to claim 17 , wherein the package comprises a dosing format which releases the at least one solid detergent composition and the at least one gel detergent composition over a plurality of stages of a dishwashing cycle or over at least one stage of a plurality of dishwashing cycles.

20. The package of claim 1 , wherein at least one of:
the at least one builder of the solid detergent composition is selected from the group consisting of hydroxycarboxylates, aminocarboxylates, dicarboxylic acid amines, phosphates, phosphonates, salts thereof, and mixtures thereof;
the at least one bleaching agent of the solid detergent composition is selected from the group consisting of a percarbonate, a manganese complex comprising triazacyclononane (TACN), or any derivatives of a TACN ligand, and mixtures thereof;
the at least one builder of the gel detergent composition is selected from the group consisting of hydroxycarboxylates, aminocarboxylates, dicarboxylic acid amines, phosphates, phosphonates, salts thereof, and mixtures thereof.

21. The package of claim 20 , wherein at least one of:
the at least one builder of the solid detergent composition is selected from the group consisting of trisodium citrate, methyl glycine diacetic acid (MGDA), N,N-dicarboxymethyl glutamic acid (GLDA), iminodisuccinic acid (IDS), tripolyphosphate, phosphonate, salts thereof, and mixtures thereof;
the at least one bleaching agent of the solid detergent composition is selected from the group consisting of coated sodium percarbonate, uncoated sodium percarbonate, tetraacetylethylenediamine (TAED), 1,4,7-trimethyl-TACN, manganese oxalate, manganese acetate, a dinuclear manganese complex, a dinuclear manganese complex comprising TACN or any derivatives of a TACN ligand, and mixtures thereof; and
the at least one builder of the gel detergent composition is selected from the group consisting of trisodium citrate, methyl glycine diacetic acid (MGDA), N,N-dicarboxymethyl glutamic acid (GLDA), iminodisuccinic acid (IDS), tripolyphosphate, phosphonate, salts thereof, and mixtures thereof.

22. The package of claim 1 , wherein the at least one bleaching agent of the solid detergent composition is present in the form of a bleach system that comprises at least one bleaching agent, at least one bleach activator, and at least one bleach catalyst.
