  • Patent number: 10420340
    Abstract: An agrochemical formulation comprising a structurant, surfactant adjuvant, and optionally an agrochemical active and/or nutrient. The structurant is a polyol ester of a C4 to C16 dicarboxylic acid, and may be obtainable by the reaction of C4 to C16 dicarboxylic acid, C2 to C8 polyol, and C16 to C30 monocarboxylic fatty acid. There is also provided a method of making the concentrate. The structurant is suitable for use in concentrates and agrochemical formulations to provide structuring in adjuvant based systems.

  • Patent number: 9861100
    Abstract: Structurants for agrochemical oil based active formulations, and in particular for use in agrochemical concentrate and diluted concentrates, for suspending solids in oil based formulations. The solids are one or more agrochemical actives and/or nutrients which are dispersed in the formulations. The structurant is polyamide formed from a dicarboxylic acid comprised from a dimer acid compound, and one or more diamine compounds. The present invention also includes methods of treating crops with such micronutrient formulations.

  • Patent number: 9681658
    Abstract: An agrochemical formulation comprising a penetrant and an agrochemical active. The penetrant is an esterified and/or etherified polyol alkoxylate obtainable by directly esterifying and/or etherifying a polyol alkoxylate. There is also provided a method of making the penetrant comprising alkoxylation of a polyol, and esterification or etherification of the formed poyol alkoxylate. The penetrant is suitable for use in agrochemical formulations to enhance penetration of the active across a leaf cuticle.
