  • Publication number: 20090325808
    Abstract: A formulation having a slightly water soluble ingredient and method for preparing the same are disclosed. The millbase formulation comprises a slightly water soluble ingredient and a dispersant comprising a water soluble or water dispersible, derivative of an alternating copolymer or a salt thereof. The alternating copolymer comprises a residue of a first comonomer and a residue of a second comonomer. In addition, the first comonomer comprises an ?,?-unsaturated oxyacid, or an anhydride or other derivative thereof. Moreover, the second comonomer comprises an olefinic compound containing one or more polymerizable double bonds, or a derivative thereof. Such formulations may be used to inhibit Ostwald ripening in agricultural as well as non-agricultural applications.

  • Patent number: 6451731
    Abstract: An emulsifiable pesticidal suspension concentrate composition is provided comprising (a) a pesticidally effective amount of a liquid pesticide of low solubility in water, for example a chloroacetamide herbicide such as acetochlor, (b) a pesticidally effective amount of a solid particulate pesticide, more particularly a salt-forming pesticide, for example a glyphosate herbicide, in solid particulate form, dispersed in the liquid pesticide, (c) a stabilizing amount of a suspension aid, (d) an emulsifying agent in an amount sufficient to emulsify the concentrate composition in a suitable volume of water to form a dilute sprayable composition, and (e) zero to an assay adjusting amount of an inert liquid in which the liquid pesticide is soluble or miscible. The concentrate composition is substantially non-aqueous. The liquid and solid pesticides are selected to be chemically compatible with each other.
