  • 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
