  • Publication number: 20180289002
    Abstract: A method of producing an amidoamine alkoxylate is disclosed that involves reacting a triglyceride, a carboxylic acid, or a combination of triglyceride and carboxylic acid with an alkyleneamine to produce an amidoamine and alkoxylating the amidoamine with an alkylene oxide. Also disclosed are amidoamine alkoxylate compositions and their use in agricultural formulations.

  • Patent number: 9433208
    Abstract: In agricultural practice it is known to use emulsifiable oils (commonly referred to a Crop Oil Concentrates, COC) as bioefficacy enhancers for pesticides, especially herbicides. Cationic surfactants are widely known to be particularly effective bio-active enhancers for herbicides, especially for glyphosate-type herbicides. The present invention includes two novel aspects: 1) While the vast majority of COCs are petroleum-based paraffinic oils or esterified seed oils, this invention embodies a new oil phase, a hydrocarbon oil such exemplified by EXXON-MOBIL'S D-130, which when combined with the surfactants described herein, exhibits surprising enhancement of herbicidal activity in field tests; and 2) COC's are designed to form stable emulsions in water. The combination of cationic surfactants and phosphate esters in this invention not only form very stable emulsions in water, but, surprisingly, also form extremely stable emulsions in concentrated liquid fertilizers, including 32-0-0 fertilizer.

  • Patent number: 8435927
    Abstract: By the present invention, a surfactant system containing glyphosate has been created which can be used to yield formulations containing an ultra-high load of glyphosate, in which the glyphosate concentration is higher than previously possible in any agriculturally-acceptable formulation. Higher loadings are desirable to reduce shipping and container costs, as well as reduce wastes. The higher loading reduces storage requirements and allows the farmer to handle less volume of pesticide. The main advantage is that maximizing the loading minimizes the cost to deliver the active ingredient, which in turn maximizes economy in use of glyphosate.

  • Patent number: 8288317
    Abstract: An agrochemical composition includes a homogeneous single-phase liquid crystal in thermodynamic equilibrium. The agrochemical composition can be a surfactant composition or a pesticide composition. The surfactant composition is a blend of surfactants, whereas a pesticide composition has an active ingredient and one or more surfactant adjuvants. A pesticide composition, or a surfactant composition in combination with an active ingredient, may be used to control pests.

  • 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: 7110051
    Abstract: Provided herein are consumer products contained in conventional containers. A consumer product packaged according to the present invention is one which exhibits birefringence, and the packaging used according to the present invention is arranged so that the consumer product is caused to exist between two layers of polarizing film and is thus capable of exhibiting the phenomenon of birefringence to consumers under ambient lighting conditions.
