Abstract

An automatic dishwashing detergent composition in unit dose form wherein the composition comprises at least about 0.2 mg of active starch degrading enzyme per gram of composition and wherein the weight of the composition is less than about 25 grams.

First claim

What is claimed is:

1 . An automatic dishwashing detergent composition in unit dose form, said composition having a total weight of less than 25 grams, said composition comprising bleach and at least 0.2 mg of an alpha-amylase having;
(a) one or more, substitutions in the following positions versus SEQ ID NO: 2: 9, 26, 149, 182, 186, 202, 257, 295, 299, 323, 339 and 345; and optionally one or more substitutions and/or deletions in the following positions: 118, 183, 184, 195, 320 and 458; or (b) at least one substitution in the following positions versus SEQ ID NO:5: M202, M208, S255, R172, and/or M261.

2 . An automatic dishwashing detergent composition according to claim 1 wherein said alpha-amylase has:
(a) three or more substitutions in the following positions versus SEQ ID NO: 2: 9, 26, 149, 182, 186, 202, 257, 295, 299, 323, 339 and 345; and one or more substitutions and/or deletions in the following positions: 118, 183, 184, 195, 320 and 458; or
(b) at least one substitution in the following positions versus SEQ ID NO:5: M202L, M202V, M2025, M202T, M202I, M202Q, M202W, S255N and/or R172Q.

3 . An automatic dishwashing detergent composition according to claim 2 wherein said alpha-amylase has:
(a) one or more of the following substitutions and/or deletions in the following positions:
R118K, D183*, G184*, N195F, R320K and/or R458K; or
(b) one of the following substitutions M202L or M202T mutations.

4 . An automatic dishwashing detergent composition according to claim 1 wherein said bleach comprises peroxy acids and/or alkali metal percarbonates.

5 . An automatic dishwashing detergent composition according to claim 1 comprising a sulfonated polymer.

6 . An automatic dishwashing detergent composition according to claim 1 comprising at least 1 mg of active protease per gram of the composition.

7 . An automatic dishwashing detergent composition according to claim 6 and wherein the protease is a low temperature protease.

8 . An automatic dishwashing detergent composition according to claim 1 comprising a lipase.

9 . An automatic dishwashing detergent composition according to claim 1 comprising an anti-redeposition agent.

10 . An automatic dishwashing detergent composition according to claim 1 wherein the anti-redeposition agent is a non-ionic surfactant or a non-ionic surfactant system having a phase inversion temperature between 40 and 70° C.

11 . An automatic dishwashing detergent composition according to claim 1 wherein the unit dose form is a water-soluble pouch

12 . An automatic dishwashing detergent composition according to claim 11 wherein said water-soluble pouch is a multi-compartment pouch having a plurality of films forming a plurality of compartments.

13 . An automatic dishwashing detergent composition according to claim 12 , wherein the pouch comprises two side-by-side compartments superposed onto another compartment wherein at least two different compartments contain two different compositions.

14 . An automatic dishwashing detergent composition according to claim 11 wherein at least two different compartments contain an anti-redeposition agent.

15 . An automatic dishwashing detergent composition according to claim 11 , wherein one compartment contains a composition in solid form and another compartment contains a composition in liquid form.

16 . A method of dishwashing in an automatic dishwashing machine comprising the step of placing a composition according to any of claims 1 - 15 into the product dispenser and releasing it during the main-wash cycle.

17 . A method of dishwashing in an automatic dishwashing machine using a detergent composition according to any of claims 11 - 15 comprising the steps of: a) placing the pouch into the product dispenser and releasing it during the main-wash cycle; and b) releasing anti-redeposition agent into the wash liquor at two different points in time of the main-wash cycle.

18 . A method of preventing grit formation in automatic dishwashing comprising practicing the method of claim 16 .
