Procedure

Glyphosate acid (275.2 g technical grade, about 87.2% purity, commonly referred to as a “wet cake”) was suspended in 183.9 g of water. Isopropylamine (83.9 g, one (1) equivalent based on the gae of the glyphosate) was slowly added to this glyphosate suspension, while maintaining mixture below about 50° C. to provide a concentrated glyphosate isopropylammonium salt solution. Then 60 g of tallowamine ethoxylate (10 EO) was added to the glyphosate isopropylammonium salt solution. The resulting concentrate had a density of 1.207 g/ml, a pH of 4.58 and contained 480 gae/l glyphosate. The resulting concentrate was found to be a clear, homogeneous solution with a cloud point greater than about 55° C. The resulting concentrate was also stable when stored at −10° C. for 14 days, with no signs of crystallization.
