Abstract

An automatic dishwashing detergent composition comprising:
a) from about 0.1% to about 20% by weight of a cleaning surfactant selected from the group consisting of an anionic surfactant, a zwitterionic surfactant, an amphoteric surfactant, and mixtures thereof; b) from about 0.1% to about 20% by weight of a cleaning amine.

First claim

What is claimed is:

1. An automatic dishwashing detergent composition comprising:
a) from about 0.1% to about 20% by weight of a cleaning surfactant selected from the group consisting of an anionic surfactant, a zwitterionic surfactant, an amphoteric surfactant, and mixtures thereof;
b) from about 0.1% to about 20% by weight of a cleaning amine,

wherein the amine is a polyetheramine selected from the group consisting of polyetheramines of Formula (I), Formula (II), Formula (III) and a mixture thereof:

wherein each of R 1 -R 12 is independently selected from H, alkyl, cycloalkyl, aryl, alkylaryl, or arylalkyl, wherein at least one of R 1 -R 6 and at least one of R 7 -R 12 is different from H, each of A 1 -A 9 is independently selected from linear or branched alkylenes having about 2 to about 18 carbon atoms, each of Z 1 -Z 4 is independently selected from OH or NH 2 , wherein at least one of Z 1 -Z 2 and at least one of Z 3 —Z 4 is NH 2 , wherein the sum of x+y is in the range of about 2 to about 200, wherein x≥1 and y≥1, and the sum of x 1 +y 1 is in the range of about 2 to about 200, wherein x 1 ≥1 and y 1 ≥1

wherein R is selected from H or a C1-C6 alkyl group, each of k 1 , k 2 , and k 3 is independently selected from 0, 1, 2, 3, 4, 5, or 6, each of A 1 , A 2 , A 3 , A 4 , A 5 , and A 6 is independently selected from a linear or branched alkylene group having from about 2 to about 18 carbon atoms or mixtures thereof, x≥1, y≥1, and z≥1, and the sum of x+y+z is in the range of from about 3 to about 100, each of Z 1 , Z 2 , and Z 3 is independently selected from NH 2 or OH, where at least two of Z 1 , Z 2 , and Z 3 are NH 2 ; and the polyetheramine has a weight average molecular weight of from about 150 to about 1000 grams/mole.

2. A composition according to claim 1 , wherein said cleaning surfactant comprises an anionic surfactant selected from the group consisting of sulfonate, sulfate, carboxylate and mixtures thereof.

3. A composition according to claim 1 wherein in said polyetheramine of Formula (I) or Formula (II), each of A 1 -A 9 is independently selected from ethylene, propylene, or butylene.

4. A composition according to claim 1 wherein the polyetheramine of Formula (I) has the following formula:

wherein n+m is from about 0 to about 8.

5. A composition according to claim 1 further comprising an aminocarboxylic builder.

6. A composition according to claim 1 wherein the composition is free of non-ionic surfactant.

7. A composition according to claim 1 further comprising a suds suppressor.

8. A composition according to claim 1 further comprising alkaline amylases possessing at least about 90% identity, with those derived from Bacillus sp. NCIB 12289, NCIB 12512, NCIB 12513, DSM 9375 (U.S. Pat. No. 7,153,818) DSM 12368, DSMZ no. 12649, KSM AP1378 (WO 97/00324), KSM K36 or KSM K38 (EP 1 022 334).

9. A composition according to claim 1 further comprising a protease with variations versus a protease that has at least about 70% identity with the amino acid sequence of SEQ ID NO:1 from EP 2 100 949 said variant protease comprises substitutions in one or more of the following positions: 9, 15, 32, 33, 48-54, 58-62, 66, 68, 94-107, 116, 123-133, 150, 152-156, 158-161, 164, 169, 175-186, 197, 198, 203-216, 239 as compared with the protease in SEQ ID NO:1 (i.e. the amino acids at the specified position, not the BPN′ numbering scheme).

10. A method of removing cooked-on, baked-on and burnt-on soils from cookware/tableware by subjecting the cookware/tableware to a composition according to claim 1 in an automatic dishwashing machine.
