Patent ID: 8476193

Claim:
A stable oil-in-water emulsion which comprises: a) a discontinuous oil phase comprising, with respect to the oil-in-water emulsion, from about 200 g/L to about 800 g/L of oil solvent, from about 1 g/L to about 200 g/L of emulsion template solvent and from about 1 g/L to about 200 g/L of cloquintocet mexyl; b) a continuous aqueous phase comprising, with respect to the oil-in-water emulsion, from about 200 g/L to about 700 g/L of water; c) an emulsifying surfactant comprising, with respect to the oil-in-water emulsion, from about 1 g/L to about 100 g/L; d) a polymeric dispersing surfactant comprising, with respect to the oil-in-water emulsion, from about 1 g/L to about 100 g/L; and e) optionally, other inert formulation ingredients; wherein the oil-in-water emulsion is stable for at least 6 weeks at 40° C. as indicated by the absence of crystals due to cloquintocet-mexyl hydrate formation as determined by examination with a microscope using polarized light.
