Aqueous alkali metal glyphosate compositions are disclosed. The compositions comprise an aqueous concentrate of an alkali metal glyphosate, a surfactant blend comprising an etheramine component, and an optional water-miscible solvent. A mixture of the surfactant blend and solvent is gel-free and monophasic. Adjusting the pH of the aqueous concentrate to be within the range of 4.0 to 4.5 surprisingly enables preparation of a highly concentrated aqueous alkali metal glyphosate composition having good elevated temperature stability and a high cloud point. For instance, a 540 g.a.e./L formulation comprising the composition exhibits good stability at 54° C. Gel-free, monophasic surfactant blends useful in the glyphosate compositions are also disclosed.
