Abstract

A phosphate-free automatic dishwashing composition including an amine and an enzyme.

First claim

What is claimed is:

1. A phosphate-free automatic dishwashing composition comprising
ii) an amine of formula III:
R 7 —N—(—R 8 )(CH2CHOH(CH2O) n -R 9 )  formula III

wherein:
R 7 and R 8 are independently selected from hydrogen, cyclic or acyclic, linear or branched C 1 to C 10 alkyl, C 1 to C10 hydroxyalkyl, polyhydroxyhydrocarbyl and polyalkoxy of formula (R 10 —O)xH with R 10 being C 1 -C 4 and x is from 1 to 15;
n is 0 or 1; and
R 9 is a C 6 to C 30 hydrocarbyl,

wherein the composition comprises a protease, an amylase and is free of anionic surfactants, wherein the composition has a pH from at least 10 to below 12, wherein the composition is adapted for use in an automatic dishwashing machine.

2. A composition according to claim 1 , wherein the composition comprises an amine of formula III, wherein in said amine of formula III, R 8 is selected from the group consisting of: hydrogen and C 1 to C 10 alkyl.

3. A composition according to claim 1 , wherein the composition comprises an amine of formula III, wherein in said amine of formula III, R 8 is selected from the group consisting hydrogen and methyl.

4. A composition according to claim 1 wherein the composition comprises an amine of formula III, wherein in said amine of formula III, R 9 is selected from the group consisting of: C 6 to C 30 alkyl.

5. A composition according to claim 1 wherein the composition comprises from about 1% to about 20% by weight thereof of the amine.

6. A composition according to claim 1 comprising:
a) from about 2 to about 15% by weight of the composition of the amine;
b) a protease;
c) an amylase;
d) from about 5 to about 40% by weight of the composition of a complexing agent;
e) from about 5 to about 40% by weight of carbonate;
from about 1 to about 30% by weight of percarbonate; and
g) from 0 to about 10% by weight of the composition of a dispersant polymer.

7. A composition according to claim 1 comprising:
a) from about 2 to about 15% by weight of the composition of the amine;
b) from about 5 to about 40% by weight of the composition of a complexing agent;
c) from about 5 to about 40% by weight of the composition of carbonate;
d) from about 1 to about 30% by weight of the composition of percarbonate; and
e) from 0 to about 10% by weight of the composition of a dispersant polymer.
