  • Publication number: 20230240287
    Abstract: This invention relates to agrochemical compositions. More specifically, the invention relates to an aqueous agrochemical composition comprising (i) water in an amount of 30 wt. % or more based on the total weight of the liquid agrochemical composition: (ii) one or more electrolyte agrochemicals dissolved in the water, wherein the total amount of electrolyte agrochemicals dissolved in the water is 20 wt. % or more based on the total amount of water in the liquid agrochemical composition; (iii) a surfactant system comprising: (a) an alkylpolyglucoside surfactant, an alkyl glucamide ester surfactant and/or an ethoxylated fatty alcohol phosphate ester surfactant; and (b) a co-surfactant comprising an anionic head group and a tail group, wherein the tail group comprises at least two alkyl, alkenyl or alkynyl groups; and (iv) one or more agrochemicals suspended in the water.

  • Publication number: 20230165255
    Abstract: The present invention relates to a liquid herbicidal composition comprising: a non-aqueous solvent system; at least one sulfonylurea herbicide in an amount of 10 wt. % or less; and two or more surfactants; and characterized in that: 80 wt. % to 100 wt. % of the total amount of surfactant in the liquid composition is made up of surfactants selected from the surfactant classes 1-14 as described herein; and at least two different surfactant classes 1-14 each account for at least 10 wt. % of the total amount of surfactant in the liquid composition. The inventors have found that, if a combination of two or more surfactants from the different surfactant classes are employed, and if a significant portion of the total amount of surfactant in the liquid composition is made of surfactants from the identified surfactant classes, then degradation of the sulfonylurea can be greatly reduced or eliminated, even in the absence of a stabilising agent.

  • Patent number: 5547918
    Abstract: A biocidal or agrochemical composition comprising particles or droplets of a substantially water-insoluble or sparingly-soluble biocidally-or agrochemically-active substance cosuspended, by an aqueous structured surfactant, with an aliphatic hydrocarbon or glyceride oil, wherein the weight ratio of said surfactant to said active substance is less than 20:1
