Cleaning composition for dishwashing

摘要

A cleaning composition comprises the reaction product of A) a chelating component and B) an acidic component different from the chelating component. The chelating component is selected from the group of methylglycine-N—N-diacetic acid (MGDA), N,N-bis(carboxymethyl)-L-glutamate (GLDA), nitrilotriacetic acid (NTA), hydroxyethylethylenediaminetriacetic acid (HEDTA), ethylenediaminetetraacetic acid (EDTA), diethylenetriaminepentaacetic acid (DTPA), and mixtures thereof. The chelating component is generally a salt or a partial-salt of the respective acid, e.g. Na3.MGDA. The B) acidic component and the A) chelating component are reacted in a molar ratio (B:A) of from about 6:1 to about 1:6 to form the reaction product. The cleaning composition further comprises a surfactant component in addition to the reaction product. The cleaning composition is useful for removing and/or preventing spotting and filming on ware surfaces in a dishwater, such as for removing and/or preventing filming and/or spotting on cookware, bakeware, tableware, dishware, flatware, and/or glassware in an automatic dishwasher (ADW).

主权项

1. A cleaning composition for dishwashing, said cleaning composition comprising:
(I) from 1 to 2 wt. % of the reaction product of;
A) a chelating component comprising methylglycine-N—N-diacetic acid (MGDA) and/or a salt thereof, andB) an acidic component comprising methanesulfonic acid (MSA),wherein said B) acidic component and A) said chelating component are reacted in a molar ratio (B:A) of from about 1:1 to about 3:1 to form the reaction product; (II) from about 10 to about 40 wt. % of a surfactant component comprising a nonionic surfactant that is a monofunctional, linear alcohol alkoxylate; and (III) from about 0.1 to about 5 wt. % a hydrotrope component that is sodium xylenesulfonate; and (IV) optionally, water, wherein said cleaning composition is free of unreacted MGDA and MSA.
