The granted patent (Publication Number: US11925179B2) discloses an aqueous herbicidal concentrate solution that includes a glyphosate component with a concentration greater than 300 grams acid equivalent per liter. The glyphosate component does not contain specific salts of glyphosate, such as the isopropylamine salt or n-propylamine salt. The solution also includes an amidoalkylamine surfactant of a defined structure (I), along with various co-surfactants with specific structures outlined in the claims.

Furthermore, the patent details the composition of the solution, including the types of co-surfactants used, such as alkoxylated tertiary amine, alkoxylated quaternary amine, alkoxylated tertiary etheramine, alkoxylated quaternary etheramine, alkoxylated etheramine oxide, alkoxylated alcohol, and phosphate ester of alkoxylated alcohol surfactant. The glyphosate salt in the solution can be selected from a range of options, including potassium salt, monoammonium salt, diammonium salt, sodium salt, and others. The concentration of the glyphosate component, as well as the mass concentration ratio of the amidoalkylamine surfactant to total co-surfactant, is also specified in the claims. Additionally, the patent includes a herbicidal method for applying the solution to unwanted plants to control or eliminate them effectively.
