  • Stable oil-in-water emulsions
    Patent number: 8476193
    Abstract: Interaction of cloquintocet mexyl in the discontinuous oil phase with water in the continuous aqueous phase of an oil-in-water emulsion, which can lead to cloquintocet mexyl hydrate formation, crystal formation and Ostwald ripening, is minimized by the use of specific surfactants and solvents which provide enhanced stability to the emulsion.
    Type: Grant
    Filed: October 4, 2010
    Date of Patent: July 2, 2013
    Assignee: Dow AgroSciences, LLC.
    Inventors: Franklin N. Keeney, Mei Li
