  • Surfactant adjuvants useful in herbicide compositions
    Patent number: 6887830
    Abstract: Surfactant adjuvants that improve the bioefficacy of herbicides by combining known surfactancy, or wetting characteristics, of sulfosuccinate or sulfosuccinamate-based surfactants, with the proven bioefficiacy characteristics of alkoxylated amine-based surfactants. The surfactant adjuvants contain an amine-based surfactant, and a sulfosuccinate or sulfosuccinamate-based surfactant. The surfactant adjuvants are combined with herbicidal active ingredients, and optionally, one or more formulation aids to form herbicide compositions that have a reduced tendency to cause eye and skin irritation and can be used to control unwanted weeds or vegetation.
    Type: Grant
    Filed: June 18, 2002
    Date of Patent: May 3, 2005
    Assignee: Huntsman Petrochemical Corporation
    Inventors: Howard Meyer Stridde, Samir S. Ashrawi, David Charles Lewis, Curtis Michael Elsik, Andrew Francis Kirby

  • Polyether diamine—based surfactant adjuvants and compositions thereof
    Patent number: 6420311
    Abstract: Surfactants that are expected to further improve the bioefficacy of herbicides. The surfactants comprise esterified alkoxylated polyether diamines, alkoxylated polyether diamines, and mixtures thereof. The present invention also provides for herbicide compositions that contain the surfactants of the present invention. The herbicide compositions comprise a herbicidal active ingredient, a surfactant of the present invention, and optionally, one or more formulation aids. The present invention additionally provides for a method of controlling unwanted weeds or vegetation using the herbicide compositions of the present invention.
