    • 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).
    • 清洁组合物包含A)螯合组分和B)不同于螯合组分的酸性组分的反应产物。 螯合组分选自甲基甘氨酸-N-N-二乙酸(MGDA),N,N-双(羧甲基)-L-谷氨酸(GLDA),次氮基三乙酸(NTA),羟乙基乙二胺三乙酸(HEDTA),乙二胺四乙酸 酸(EDTA),二亚乙基三胺五乙酸(DTPA)及其混合物。 螯合组分通常是相应酸的盐或部分盐,例如。 Na3.MGDA。 B)酸性组分和A)螯合组分以约6:1至约1:6的摩尔比(B:A)反应以形成反应产物。 除了反应产物之外,清洁组合物还包含表面活性剂组分。 清洁组合物可用于去除和/或防止洗碗水中的器皿表面上的斑点和成膜,例如用于去除和/或防止在炊具,烤盘,餐具,餐具,餐具和/或玻璃器皿上的成膜和/或斑点。 自动洗碗机(ADW)。
