Abstract
Official abstract text for this publication.
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 inorganic items during a washing or rinsing process, in particular during an automatic dishwashing process.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of automatic dishwashing, comprising: supplying a composition to an automatic dishwashing machine; and washing wares in the machine, wherein the composition comprises a polyethyleneimine and/or salts thereof and at least one amphoteric polymer, wherein the amphoteric polymer is a water-soluble or water-dispersible copolymer including, in the form of polymerized units, at least one monomer having an amine functional group and at least one hydrophilic acidic monomer, wherein the composition is an alkaline automatic dishwashing detergent composition with a pH from 8 to 12, wherein the method results in good rinse performance, wherein the composition is phosphate free, wherein the number average molecular weight of the polyethyleneimine and/or salts thereof is in the range of 100 to 5,000,000, and wherein the polyalkyleneimine is in an 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 less than about 4 w % of the composition. 2. The method according to claim 1 , wherein the at least one amphoteric polymer is a hydrophilic polymer. 3. The method according to claim 2 , wherein the hydrophilic polymer is an aqueous based acrylic acid amine-functional polymer. 4. The method according to claim 2 , wherein the hydrophilic polymer is a quaternized ammonium acrylamide acrylic acid copolymer. 5. The method according to claim 1 , wherein the composition is provided in monodose form. 6. The method according to claim 1 , comprising washing glassware in the automatic dishwasher. 7. The method according to claim 1 , wherein the composition is released into a wash cycle of the machine. 8. The method according to claim 1 , wherein the composition has a pH from 9 to 11.
