| Zusammenfassung: | This disclosure provides a chelating composition having a pH of at least about 9 and comprising: water; and the tetrasodium salt of glutamic acid N,N-diacetic acid present in an amount of at least about 50 weight percent based on a total weight of the chelating composition as determined using an Fe-Total Sequestering Value, wherein the chelating composition has a viscosity of less than about 1350 mPa.s measured at about 5°C, or less than about 350 mPa.s measured at about 20°C, each using a Brookfield DV II plus viscometer with spindle S18 and a temperature controlled bath. |
