Abstract:
A chelating composition suitable for low-temperature use or storage is disclosed. The chelating compositions include 20 to 70 wt. percent of a polar solvent and 30 to 80 wt. percent of a first component of the formula: wherein R is a hydroxyalkyl group and each R′ is individually selected from the group consisting of hydrogen, unsubstituted or inertly substituted alkyl groups, carbonyl-containing alkyl groups, carboxylate-containing alkyl groups, hydroxyalkyl groups and alkoxy groups; R″ is selected from the group consisting of hydrogen, unsubstituted or inertly substituted alkyl groups; carbonyl-substituted alkyl groups, carboxylate-containing alkyl groups, hydroxyalkyl groups and alkoxy groups; M1 and M2 are alkali metal ions, wherein the M1 has a higher atomic weight than M2; wherein x+y=n and the mole fraction of M1 is greater than 0.70 to 1. Methods of suppressing crystallization and methods of cleaning surfaces employing the compositions described herein are also disclosed.
