Abstract

An automatic dishwashing detergent composition comprising:
a. at least 0.1 mg of active protease per gram of composition, wherein the protease is a variant of a protease that has at least 70% identity with the amino acid sequence of SEQ ID NO:1. wherein said variant comprise variations in one or more of the following positions: 32, 33, 48-54, 58-62, 94-107, 116, 123-133, 150, 152-156, 158-161, 164, 169, 175-186, 197, 198, 203-216 as compared with the protease in SEQ ID NO:1; and b. at least 0.05 mg of an active low temperature amylase per gram of composition.

First claim

What is claimed is:

1 . An automatic dishwashing detergent composition comprising:
a. at least 0.1 mg of active protease per gram of composition, wherein the protease is a variant of a protease that has at least 70% identity with the amino acid sequence of SEQ ID NO:1. wherein said variant comprise variations in one or more of the following positions: 32, 33, 48-54, 58-62, 94-107, 116, 123-133, 150, 152-156, 158-161, 164, 169, 175-186, 197, 198, 203-216 as compared with the protease in SEQ ID NO:1; and b. at least 0.05 mg of an active low temperature amylase per gram of composition.

2 . An automatic dishwashing detergent composition according to claim 1 wherein the protease comprises the variations G116V+S126L+P127Q+S128A.

3 . An automatic dishwashing detergent composition according to claim 1 wherein the low temperature amylase is a variant with:
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
b. optionally with one or more of the substitutions and/or deletions in the following positions: 118, 183, 184, 195, 320 and 458, which if present, comprise R118K, D183*, G184*, N195F, R320K and/or R458K.

4 . An automatic dishwashing detergent composition according to claim 1 wherein the low temperature amylase is a variant comprising at least one substitution in the following positions versus SEQ ID NO:4: M202, M208, 5255, R172, and/or M261.

5 . An automatic dishwashing detergent composition according to claim 1 comprising at least 1.5 mg of active protease per gram of the composition.

6 . An automatic dishwashing detergent composition according to claim 5 further comprising at least about 0.2 mg of low temperature amylase per gram of composition.

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

8 . An automatic dishwashing detergent composition according to claim 1 further comprising an anti-redeposition agent and/or a sulfonated polymer.

9 . An automatic dishwashing detergent composition according to claim 1 wherein the composition is in the form of a water-soluble pouch and wherein the weight of the composition is from about 10 to about 25 grams.

10 . The automatic dishwashing detergent composition according to claim 9 , wherein the pouch is a multi-compartment pouch having a plurality of films forming a plurality of compartments.

11 . The automatic dishwashing detergent composition according to claim 10 , wherein the pouch comprises two side-by-side compartments superposed onto another compartment and at least two different compartments, respectively comprising two different compositions.

12 . A method of dishwashing in an automatic dishwashing machine using a detergent composition according to claim 1 wherein the composition is in unit dose form and the weight of the composition is from about 10 to about 25 grams comprising the steps of placing the pouch into the product dispenser and releasing it during the main-wash cycle.
