  • Biocide compositions
    Patent number: 9173398
    Abstract: Described is a biocide composition, comprising: a herbicide; a fatty acid amide; a fatty acid; and optionally an emulsifier and/or a polyol. The composition exhibits an improved stability, especially at lower temperatures, and is both environmentally friendly and non-toxic.
    Type: Grant
    Filed: July 2, 2012
    Date of Patent: November 3, 2015
    Assignee: Cognis IP Management GmbH
    Inventors: Phyllis Barker, Alefesh Hailu
  • Emulsifier system and pesticidal formulations containing the emulsifier system
    Patent number: 9072294
    Abstract: The invention is an emulsifier adjuvant system for forming a substantially solventless or solvent free emulsifiable pesticidal composition. The emulsifier system comprises from about 25 to about 80% by weight, of surfactants in the emulsifier system, of at least one anionic surfactant having an average HLB value of from about 6 to about 11; and from about 20 to about 75% by weight of surfactants in the emulsifier system of at least one nonionic surfactant having an average HLB value of from about 11 to about 18. The emulsifier and adjuvant system of the invention can form emulsifier concentrates of solventless pesticidal compositions with a concentration of the pesticidal composition up to about 90% by weight.

  • Fatty acid ester blends as carriers for pesticide active ingredients
    Publication number: 20070129253
    Abstract: An agricultural pesticide composition containing: (a) a solvent which is a mixture of fatty acid alkyl esters corresponding to formula I: R1CO—OR2??(I) wherein R1CO is an aliphatic acyl group containing 12 to 18 carbon atoms and R2 is a linear or branched alkyl group containing 1 to 4 carbon atoms; and (b) a biologically active ingredient is described. A process of treating a target substrate with the composition is also disclosed.
