| description | This disclosure provides a method of forming a chelating composition, said method comprising the steps of: providing a first mixture comprising water and the tetrasodium salt of glutamic acid N,N-diacetic acid and having a pH of greater than about 10.5 measured as an about 1 wt% solution;providing a second mixture comprising water and the tetrasodium salt of glutamic acid N,N-diacetic acid and having a pH of less than about 7; and combining the first and second mixtures to form the chelating composition comprising the tetrasodium salt of glutamic acid N,N-diacetic acid in an amount of at least about 45 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 pH of at least about 9 measured as an about 1 wt% solution and 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 S 18 and a temperature controlled bath. |
