Abstract | The present disclosure provides a chelating composition having a pH of at least about 9 and comprising: water; and a tetrasodium salt of glutamic acid N, N-diacetate present in an amount of at least about 50% by weight based on the total weight of the chelating composition, determined using a Fe-total chelation value wherein the chelating composition has a viscosity of less than about 1350 mPa.s at about 5 DEG C or less than about 350 mPa.s, each measured using a Brookfield DV II plus viscometer having a S18 rotor and a temperature control bath.
本公开提供了一种螯合组合物,其具有至少约9的pH值并且包含:水;和以基于螯合组合物的总重量至少约50重量%的量存在的谷氨酸N,N-二乙酸四钠盐,使用Fe-总螯合值确定,其中所述螯合组合物具有各自使用具有S18转子和温度控制浴的Brookfield DV II plus粘度计在约5℃下测得的小于约1350mPa.s或在约20℃下测得的小于约350mPa.s的粘度。 |
