The present invention relates to an improved detergent composition for use in the protection of non-metallic inorganic materials such as glassware in automatic ware washing machines.
First claim
Opening claim text (preview).
1 . An automatic dishwasher detergent composition comprising a polyethyleneimine, wherein the polyethyleneimine is contained within one or both a gel and liquid phase of the composition, and the amount of the polyethyleneimine is less than 1% by weight of the composition. 2 . The composition as claimed in claim 1 , wherein the composition comprises less than 0.5%, by weight of the polyethyleneimine. 3 . The composition as claimed in claim 1 , wherein the composition consists of the gel or phase. 4 . The composition as claimed in claim 1 , wherein the composition comprises at least two separate phases. 5 . The composition as claimed in claim 4 , wherein one of the at least two separate phases is the solid phase selected from the group consisting of powder, granules, and a compressed solid. 6 . The composition as claimed in claim 1 , wherein the gel or liquid phase which comprises the polyethyleneimine contains no more than 5% water, by weight of the gel or liquid phase. 7 . The composition as claimed in claim 1 , wherein the composition comprises no more than 4% by weight of anionic surfactant. 8 . The composition as claimed in claim 1 , wherein the composition comprises at least 10% by weight builder. 9 . The composition as claimed in claim 1 , wherein the composition comprises one or more of protease, amylase, and bleach. 10 . The composition as claimed in claim 1 , wherein the polyethyleneimine has a molecular weight between 100 and 2500. 11 . The composition as claimed in claim 1 , wherein the polyethyleneimine is a liquid ingredient at room temperature. 12 . A product comprising the composition as claimed in claim 1 , which is in a unit dose form. 13 . A method of automatic dishwashing comprising: supplying a composition as claimed in claim 1 to an automatic dishwasher; and releasing the composition into a wash cycle of the automatic dishwasher. 14 . The method as claimed in claim 13 further comprising washing glassware in the automatic dishwasher. 15 . (canceled) 16 . The composition as claimed in claim 1 , wherein the composition comprises between 0.0001 and 0.0025% by weight of the polyethyleneimine. 17 . The composition as claimed in claim 1 , wherein the composition consists of the liquid phase. 18 . The composition as claimed in claim 1 , wherein the gel or liquid phase which comprises the polyethyleneimine comprises at least 10% surfactant by weight of the gel or liquid phase. 19 . The composition as claimed in claim 1 , wherein the composition comprises no anionic surfactant. 20 . The composition as claimed in claim 1 , wherein the polyethyleneimine has a molecular weight between 700 and 900. 21 . The composition as claimed in claim 1 , wherein the polyethyleneimine contains no alkoxylate groups. 22 . The composition as claimed in claim 1 , wherein the polyethyleneimine is homopolymeric. 23 . The composition as claimed in claim 1 , wherein the polyethyleneimine contains primary, secondary and tertiary amine groups, and has a ratio of primary to secondary amine groups between 1:0.5 and 1:1. 24 . A product comprising the composition as claimed in claim 1 , which is housed within a water soluble or water dispersible film or container.
