Abstract

The present invention provides the use of a composition comprising a polyalkyleneimine and/or salts or derivative thereof and an amphoteric polymer for the prevention of corrosion of non-metallic in organic items during a washing or rinsing process, in particular during an automatic dishwashing process.

Claims (16)

1. A composition comprising:

a polyalkyleneimine; and

an amphoteric polymer;

wherein the polyalkyleneimine is in the amount of 0.0001 to less than 0.1 wt % of the composition and the amphoteric polymer is in an amount between 0.01 to 10 wt % of the composition;

wherein the number average molecular weight of the polyalkyleneimine is in the range of from 100 to 5,000,000; and

wherein the amphoteric polymer is a quaternized ammonium acrylamide acrylic acid copolymer.

2. The composition according to claim 1 , wherein the polyalkyleneimine comprises a polyethyleneimine.

3. The composition according to claim 1 , wherein the composition is an automatic dishwashing detergent.

4. The composition according to claim 1 , wherein the composition is an automatic dishwashing rinse aid comprising the polyalkyleneimine in an amount between 0.0005 wt % to less than 0.1 wt % of the composition.

5. The composition according to claim 1 , wherein the composition is a water softening salt composition.

6. The composition according to claim 1 , wherein the composition is a machine cleaner/machine additive composition.

7. The composition according to claim 1 , wherein the average molecular weight of the polyalkyleneimine is in the range of 400 to 100,000.

8. The composition according to claim 1 , wherein the composition comprises at least one formulation selected from the group consisting of a liquid, a gel, a powder and a tablet.

9. The composition according to claim 8 , wherein the composition is packed into a water soluble pouch that is sub-divided such that each formulation is separated from the other formulations.

10. The composition according to claim 3 , comprising the polyalkyleneimine in an amount between 0.001 wt % to less than 0.1 wt % of the composition.

11. The composition according to claim 3 , wherein the composition is phosphate free.
