Abstract
Description
[Technical field]
[0001] The present invention relates to compositions comprising isocycloceram, more particularly to formulations such as dispersible concentrates, dilutions of such formulations, more particularly in agricultural spray tanks, and the use of such compositions to combat and / or control animal pests. [Background technology]
[0002] Isocycloceram is an insecticidal pesticide. However, it has been found that the use of such active ingredients poses many problems when using traditional formulation techniques, such as the fact that dilution of the formulation with water-miscible solvents promotes crystal growth of the less water-soluble active ingredients, and that dilutions of the formulation are difficult to stabilize, as the formulations are often not very tolerant of changes in conditions such as changes in dilution ratio, temperature, and water quality, among other parameters. Summary of the Invention [Problem to be solved by the invention]
[0003] The present invention aims to overcome the problems associated with the prior art techniques by proposing an isocycloceram-containing composition having dilution stability, in particular ensuring good solubility of isocycloceram even at 100 g / l.
[0004] To this end, the present invention provides: (a) isocycloceram, and (b) a lignin compound having an average molecular weight of 10,000 g / mol or less The present invention provides a composition comprising: [Means for solving the problem]
[0005] By combining said lignin compounds with isocycloceram, all of the above problems were overcome. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0007] Isocycloserum can include the isomer (5S,4R) which is 4-[(5S)-5-(3,5-dichloro-4-fluoro-phenyl)-5-(trifluoromethyl)-4H-isoxazol-3-yl]-N-[(4R)-2-ethyl-3-oxo-isoxazolidin-4-yl]-2-methyl-benzamide (CAS number: 1309959-62-3), and optionally at least one of the isomers selected from the isomer (5S,4S), the isomer (5R,4R), the isomer (5R,4S), and any combination thereof. In the present invention, the isomer (5S,4S) is 4-[(5S)-5-(3,5-dichloro-4-fluoro-phenyl)-5-(trifluoromethyl)-4H-isoxazol-3-yl]-N-[(4S)-2-ethyl-3-oxo-isoxazolidin-4-yl]-2-methyl-benzamide; the isomer (5R,4R) is 4-[(5R)-5-(3,5-dichloro-4-fluoro-phenyl)-5-(trifluoromethyl)-4H -isoxazol-3-yl]-N-[(4R)-2-ethyl-3-oxo-isoxazolidin-4-yl]-2-methyl-benzamide; and the isomer (5R,4S) is 4-[(5R)-5-(3,5-dichloro-4-fluoro-phenyl)-5-(trifluoromethyl)-4H-isoxazol-3-yl]-N-[(4S)-2-ethyl-3-oxo-isoxazolidin-4-yl]-2-methyl-benzamide. When isocycloserum further comprises at least one isomer selected from the isomer (5S,4S), the isomer (5R,4R), the isomer (5R,4S), and any combination thereof, it may comprise the isomer (5S,4R) in a molar proportion of more than 50%, for example at least 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, 96%, 97%, 98% or 99%, based on the total amount of isomers (5S,4R), (5S,4S), (5R,4R) and (5R,4S).
[0008] The composition of the present invention may contain from 0.01% to 70% by weight of isocycloserum, preferably from 0.1% to 50% by weight of isocycloserum, preferably from 1% to 30% by weight of isocycloserum, more preferably from 5% to 20% by weight of isocycloserum, based on the total weight of the composition.
[0009] The lignin compounds of the present invention may have an average molecular weight of up to 5000 g / mol. In a preferred embodiment, the lignin compounds may have an average molecular weight of at least 1000 g / mol.
[0010] In the present invention, the expression "average molecular weight" means an approximate molecular weight. The molecular weight, or in other words the molar mass, of a lignin compound can be easily determined by methods known in the art, such as gel permeation chromatography (GPC).
[0011] The lignin compound of the present invention can more specifically be kraft lignin.
[0012] In other particular embodiments, the lignin compound can be a non-sulfonated lignin. In a preferred embodiment, the lignin compound can be a non-sulfonated kraft lignin.
[0013] Non-sulfonated Kraft lignin is produced using the Kraft process (also known as the sulfate process), i.e., with sodium hydroxide (NaOH) and sodium sulfide (Na 2 S) which produces lignin that is not sulfonated, unlike that produced by the acid sulfite process.
[0014] The composition of the present invention may contain, relative to the total weight of the composition, 0.01% to 30% by weight of the lignin compound, preferably 0.1% to 20% by weight of the lignin compound, and more preferably 0.1% to 10% by weight of the lignin compound.
[0015] The composition of the present invention may further comprise (c) an acrylic graft copolymer.
[0016] The acrylic graft copolymers typically have a comb or star structure, and preferably a comb structure.
[0017] Graft copolymers are branched copolymers in which the components that form the side chains are structurally different from the components that form the backbone.
[0018] Comb polymers are comprised of a main chain (backbone) having branch points from each of which extend linear side chains.
[0019] Star polymers comprise a multifunctional center from which at least three polymer chains radiate out.
[0020] In a preferred embodiment, the acrylic graft copolymer can be an amphiphilic copolymer.
[0021] More specifically, the acrylic graft copolymer comprises at least one component A (hydrophilic part) that is solubilized by an aqueous medium, and at least one other component B that is hydrophobic.
[0022] Suitable acrylic graft copolymers may contain as the hydrophilic side chains polyethylene glycol, mono-methyl ether of polyethylene glycol, poly(vinylpyrrolidone), poly(acrylamide) or poly(vinyl alcohol), while the hydrophobic backbone may contain polymers and copolymers of styrene, methyl acrylate, methyl methacrylate, ethyl acrylate, 2-ethylhexyl acrylate, lauryl methacrylate or vinyl acetate.
[0023] Such acrylic graft copolymers can be prepared, for example, by converting mono-methyl ethers of polyethylene glycol to acrylic or methacrylic acid esters, which are then subjected to radical polymerization with other unsaturated monomers such as styrene, ethyl acrylate or methyl methacrylate. Such acrylic graft copolymers can also be prepared by reacting a hydrophobic polymer backbone consisting of chemically reactive sites such as carboxyl, hydroxyl or amine groups with monomeric alkylene oxides such as ethylene oxide and propylene oxide to form hydrophilic side chains.
[0024] More preferably, the acrylic graft copolymer is a nonionic polymer, more particularly one having a comb structure.
[0025] In the present invention, the acrylic graft copolymer can contain polyethylene glycol and / or mono-ether polyethylene glycol side chains.
[0026] The acrylic graft copolymer can also include a backbone derived from acrylate and / or methacrylate monomers.
[0027] Even more preferably, the acrylic graft copolymer may comprise a backbone derived from acrylate and / or methacrylate monomers and side chains comprising polyethylene glycol and / or mono-ether polyethylene glycol, which more particularly gives the polymer a comb structure.

[0061] Examples 1-4 are prepared as follows: the required amount of lactamide compound and ether solvent are weighed into a suitable container and mixed until homogeneous. The required amount of isocycloceram is then added with stirring and allowed to stand until the isocycloceram is visually dissolved. The mixture can optionally be heated to 40°C to increase the rate of dissolution. The acrylic graft copolymer and lignin compound are then added with continued stirring and allowed to stand until the blend is homogeneous and cooled back to ambient temperature (25°C) if necessary.
[0062] [Table 1]
[0063] Table 2 summarizes the results based on the following assessments: - Dissolution: After the formulation is prepared, the sample is visually inspected to determine if all solids in the formulation are completely dispersed. This test determines if the lignin compounds are completely dispersed in the formulation. Undispersed lignin compounds are observed as brown / black particulate matter. - Dilution Properties: The dilution properties of the formulations were evaluated according to CIPAC MT180 method by varying the type of water, temperature and dilution ratio as shown in the table below. In this test, both the opacity of the dilution and the amount of sediment were recorded. Dilution stability is good if less than 0.1 ml of sediment is present after the dispersible concentrate formulation is left undisturbed for 24 hours.
