AI Technical Summary
Existing methods for formulating agrochemical compositions with two solid and one liquid active ingredients often fail to produce stable suspoemulsions due to solubility issues between the solid ingredients and the liquid, leading to instability or incomplete formulation.
The formulation of stable agrochemical compositions, particularly suspoemulsions, is achieved by ensuring a high content of the oil phase, comprising at least 30-60% of the composition, and carefully selecting active ingredients with solubility ratios between 1 to 33 g/100 g, using a combination of suspension concentrate (SC) and emulsifiable concentrate (EC) processes.
The method results in stable agrochemical compositions that maintain stability under various conditions, including high temperatures, by ensuring proper solubility and phase mixing of the active ingredients, enhancing their effectiveness and application reliability.

Abstract
Description
[Technical field]
[0001] The present disclosure relates to a stable agrochemical composition comprising two solid active ingredients and one liquid active ingredient, and a preparation process thereof. More specifically, the present disclosure relates to a stable agrochemical composition, for example a suspoemulsion (SE), comprising penoxsulam, pretilachlor, and further comprising solid active ingredients, in particular a solid toxic safener, for example fenclorim, and a preparation process thereof. Alternatively, the present disclosure relates to a stable agrochemical composition, for example a suspoemulsion (SE), comprising pretilachlor, fenclorim, and further comprising solid active ingredients selected from the group consisting of penoxsulam, pyrazosulfuron-ethyl, bensulfuron-methyl, quinclorac, oxyfluorfen, oxadiazon, cyhalofop-butyl, pyriminobac-methyl, clomazone (dimethasone), pyribenzoxim, oxadiargyl, and simetryn, and a preparation process thereof. [Background technology]
[0002] It is common to combine two or more agrochemical active ingredients with different mechanisms of action to expand the scope of application, such as the weed spectrum, or to produce a synergistic effect. In the herbicide field, in some cases, a safener is also added to the agrochemical composition as an active ingredient to protect the crop. For example, fenclorim is generally used with pretilachlor in a ratio of 1:2 to 1:5 (for example, 1:3 or 1:4). Therefore, when pretilachlor is combined with another herbicide, such as penoxsulam, for example, to expand the weed spectrum, and fenclorim is also used at the same time, an agrochemical composition (particularly in this case a herbicidal composition) containing three active ingredients, two of which are solid and one of which is liquid, must be formulated. To formulate an agrochemical composition containing two solid active ingredients and one liquid active ingredient, a suspoemulsion (SE) is usually chosen, especially when at least one of the two solid active ingredients is insoluble in water or in the liquid active ingredient. Summary of the Invention [Problem to be solved by the invention]
[0003] Usually, to blend an SE of two solid active ingredients and one liquid active ingredient, it is common to grind the two solid active ingredients into micrometer-sized powders and then disperse these powders in the liquid active ingredient. However, this route is not always successful, since there may be cases where no SE is blended or no stable SE is obtained. In particular, when either one of the two solid active ingredients has a solubility of 1-33 g / 100 g (particularly 8-15 g / 100 g) in the liquid active ingredient at room temperature, it has been found that there may be cases where no SE is blended or no stable SE is obtained by the above-mentioned conventional route. It has also been found that, in particular, when either one of the two solid active ingredients has a solubility of 1-33 g / 100 g in the liquid active ingredient at room temperature, even the route employing a combination of EC and SC or a combination of EW and SC may not guarantee successful blending of a stable SE. [Means for solving the problem]
[0004] In order to solve problems in the existing technical field, the inventors have completed the present disclosure.
[0005] Surprisingly, when either one of the two solid active ingredients has a solubility of 1 to 33 g / 100 g in the liquid active ingredient at room temperature, a pharmaceutical composition containing two solid active ingredients and one liquid active ingredient can be used. It has now been found that agrochemical compositions including, for example, stable SEs comprising two solid active ingredients and one liquid active ingredient can be successfully prepared by combining an EC with an SC, for example by careful selection of the active ingredients in each of the EC or SC, especially when the content of the oil phase is very high, for example at least 30 weight percent based on the total weight of the composition, preferably at least 40 weight percent based on the total weight of the composition, preferably at least 50 weight percent based on the total weight of the composition, preferably at least 60 weight percent based on the total weight of the composition.

[0082] Throughout this application, the description of various embodiments uses the term "comprising"; however, those of ordinary skill in the art will understand that in some specific instances, the embodiments can instead be described using the language "consisting essentially of" or "consisting of."
[0083] For a better understanding of the present teachings and without limiting the scope of the present teachings, unless otherwise specified, all numbers expressing amounts, percentages or proportions, as well as other numerical values used in the specification and claims, should be understood to be modified in all cases by the term "about". Thus, unless otherwise stated to the contrary, the numerical parameters set forth in the following specification and the appended claims are approximations that may vary depending on the desired properties sought.

[0084] First aspect In a first aspect, the present disclosure provides a method for producing a method for treating a cancer cell comprising: a first active ingredient that is solid at room temperature and insoluble in water at room temperature; a second active ingredient that is a solid at room temperature; a third active ingredient that is liquid at room temperature; and water A stable agrochemical composition comprising: A stable agrochemical composition is provided, in which a first active ingredient is insoluble in a third active ingredient at room temperature, and a second active ingredient has a solubility in the third active ingredient of 1 to 33 g / 100 g at room temperature.
[0085] The first active ingredient is solid at room temperature and insoluble in water at room temperature. Usually, the solubility of the first active ingredient in water at room temperature is less than 0.1 g / L, preferably less than 0.08 g / L. The first active ingredient is slightly soluble to insoluble in the third active ingredient at room temperature. Usually, the solubility of the first active ingredient in the third active ingredient at room temperature is less than 1 g / 100 g, preferably less than 0.2 g / 100 g.
[0086] The second active ingredient is a solid at room temperature and the second active ingredient is a solid at room temperature. Within the range of 1 to 33 g / 100 g, the solubility of the second active ingredient in the third active ingredient at room temperature can be 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 12.1, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, or 33 g / 100 g, or any range formed by selecting any two of the above solubilities as endpoints, for example, the solubility of the second active ingredient in the third active ingredient at room temperature can be 2 to 30 g / 100 g, or 5 to 25 g / 100 g. Preferably, the second active ingredient has a solubility in the third active ingredient at room temperature of 2-28 g / 100 g, 5-20 g / 100 g, 7-18 g / 100 g, 8-15 g / 100 g, 9-14 g, or 11-13 g / 100 g. For example, the second active ingredient has a solubility of 12.1 g / 100 g in the third active ingredient at room temperature.
[0087] Surprisingly, without being bound by theory, it has now been found that the solubility of the second solid active ingredient in the third liquid active ingredient at room temperature is important to understand why in some cases stable agrochemical compositions containing three active ingredients, particularly stable SEs containing three active ingredients, are not possible to formulate. If the second active ingredient has a solubility of 1-33g / 100g in the third active ingredient at room temperature, stable agrochemical compositions containing three active ingredients, particularly stable SEs containing three active ingredients, may not be formulated at all or may not be obtained by the conventional routes described above, and in some cases, also depending on the amounts of the second active ingredient and the third active ingredient. It has also now been found that in some cases, particularly if the second solid active ingredient has a solubility of 1-33g / 100g in the third liquid active ingredient at room temperature, the route employing a combination of EC and SC or a combination of EW and SC may not guarantee successful formulation of a stable SE. This is particularly true when the second active ingredient has a solubility of 1 to 33 g / 100 g in the third active ingredient at room temperature, and when the solubility of the second active ingredient in the third active ingredient differs by 1 g / 100 g or more between room temperature and 54° C., and in some cases also depends on the amounts of the second active ingredient and the third active ingredient.
[0088] If the solubility of the second solid active ingredient in the third liquid active ingredient is high enough, and if the amounts of the second active ingredient and the third active ingredient are such that the second active ingredient is completely dissolved in the third active ingredient regardless of whether it is at room temperature or at 54° C., a stable SE is easily formulated by the conventional route described above. On the contrary, if the solubility of the second solid active ingredient in the third liquid active ingredient is low enough, considering the amounts of the second active ingredient and the third active ingredient, a person skilled in the art would not even consider formulating the SE by the conventional route described above.
[0089] The third active ingredient is a liquid at room temperature.
[0090] The first active ingredient, the second active ingredient, and the third active ingredient may be independently selected from the group consisting of insecticide compounds, fungicide compounds, bactericide compounds, herbicide compounds, safener compounds, acaricide compounds, nematicides compounds, bird repellents compounds, and plant nutrients compounds. Preferably, the first active ingredient, the second active ingredient, and the third active ingredient are all selected from herbicidal active ingredients. For example, both the first and third active ingredients are herbicide compounds, and the second active ingredient is a safener.

[0111] In general, the stable composition of the present disclosure may contain particles, and in some cases, may contain different types of particles.For example, when the stable composition is an SE, there are at least two types of particles, which are solid particles and liquid oil particles, and there are at least three phases, including a suspension phase formed by suspended solid particles, an emulsion phase formed by liquid oil particles, and a continuous phase formed by water.In this case, the solid particles in the suspension phase are solid particles of a first solid active ingredient suspended in water, and the liquid oil particles in the emulsion phase are formed by a third active ingredient and a second active ingredient dissolved in an organic solvent.In one embodiment, the stable composition is an SE, and the first active ingredient is formed by a suspension phase formed by a liquid oil particle. The composition includes solid particles formed by dissolving the third active ingredient in the organic solvent and liquid oil particles formed by dissolving the second active ingredient in the organic solvent, and the average particle size d90 can be <15 μm, preferably <7 μm, based on all particles. In an embodiment, the solid particles can have an average particle size d90 of <15 μm, preferably <7 μm, and the liquid oil particles can have an average particle size d90 of <5 μm, preferably <2 μm. The average particle size d90 can be measured by a laser diffractometer or a microscope.

The first active ingredient, water, and some additives such as antifoaming agents, thickeners, and antifreeze agents are present in the aqueous phase, while the second and third active ingredients, organic solvents, and other additives are present in the oil phase.

[0113] Second Aspect In a second aspect, the present disclosure provides a process for preparing a stable agrochemical composition according to the first aspect, comprising: a) forming a suspension concentrate (SC) of a first active ingredient; b) forming an emulsifiable concentrate (EC) of the second active ingredient and the third active ingredient; and c) Mixing the SC with the EC and any other ingredients. Includes.
[0114] It has also been found herein that, particularly when (1) the first active ingredient is insoluble in water or the third active ingredient at room temperature, and (2) the second solid active ingredient has a solubility of 1-33 g / 100 g in the liquid third active ingredient at room temperature, agrochemical compositions comprising stable two solid active ingredients and one liquid active ingredient, particularly stable SEs comprising two solid active ingredients and one liquid active ingredient, can be successfully prepared by combining an EC with a SC by carefully selecting the active ingredients in each of the EC and SC. Specifically, the present inventors have unexpectedly discovered that a stable agrochemical composition, particularly a stable SE, can be prepared by mixing a suspension concentrate (SC) of a first active ingredient with a suspension concentrate (SCE) of a second active ingredient, when the content of the oil phase (the sum of the second and third active ingredients, the organic solvent, and any additives used herein) is at least 30 weight percent based on the total weight of the composition, preferably at least 40 weight percent based on the total weight of the composition, preferably at least 50 weight percent based on the total weight of the composition, and preferably at least 60 weight percent based on the total weight of the composition. It has been found that the SE can be successfully formulated only when the second active ingredient is mixed with an emulsifiable concentrate (EC) of the first active ingredient and the second active ingredient. More specifically, the present inventors have unexpectedly found that when the second active ingredient is added to the SC together with the first active ingredient, no matter how the third active ingredient is formulated (e.g., in the EC or EW), a stable agrochemical composition, especially a stable SE, can not be successfully formulated. The present inventors have also unexpectedly found that when the second active ingredient is combined with the third active ingredient in the EW, no matter how the first active ingredient is combined with the SC, especially when the content of the oil phase (the sum of the second and third active ingredients, the organic solvent, and any optional additives) is at least 30 weight percent based on the total weight of the composition, preferably at least 40 weight percent based on the total weight of the composition, preferably at least 50 weight percent based on the total weight of the composition, preferably at least 60 weight percent based on the total weight of the composition.
[0115] Step a) may include mixing the first active ingredient, the first amount of water, and any other additives to form a homogenous suspension. Other optional additives that may be used in step a) may include, but are not limited to, antifreeze agents, antifoam agents, dispersants, other possible surfactants, and combinations thereof. A homogenous suspension can be determined by visual evaluation of appearance, active ingredient content analysis at different points of the sample, and / or microscopic testing at different points of the sample. The mixing step may be performed by any means in the art, such as a mixer. The mixing time is selected based on the nature and amount of the first active ingredient, the nature and amount of any other additives, and their relative amounts compared to the water. In general, the mixing time may be from 5 minutes to 60 minutes, depending, for example, on the total amount of material. The amount of water in the first amount may be determined by the minimum amount of water required to successfully disperse the first active ingredient and the total amount of water used in the composition.
[0116] Step a) may further comprise milling the obtained suspension until the desired average particle size is obtained, for example until an average particle size d90 of ≦15 μm, preferably ≦7 μm, more preferably ≦5 μm is achieved. The milling step may be carried out by any suitable equipment in the art, for example NETZSCH MINIZETA. As described in the first aspect, the average particle size may be measured by any conventional method in the art, for example a laser particle size analyzer Malvern MS3000. The milling time may be determined by the desired average particle size, the equipment used for milling and the total amount of material. In general, the milling time may be, for example, 5 minutes to 60 minutes depending on the total amount of material and the desired particle size.
[0117] Step b) may include mixing the second and third active ingredients, the organic solvent, and any other optional additives to form a clear liquid. The other optional additives may include, but are not limited to, wetting agents, emulsifiers, bactericides, other possible surfactants, and combinations thereof. Mixing may be performed by any means in the art, such as a mixer. The mixing time may be selected based on the nature and amount of the second and third active ingredients, the nature and amount of any other additives, and their relative amounts compared to the organic solvent, etc. In general, the mixing time may be from 5 minutes to 30 minutes, depending on, for example, the total amount of material.
[0118] The mixing in step b) may be carried out under heating to promote dissolution. Heating is optional. Heating may be carried out by any means in the art, for example a magnetic stirring heater. The heating temperature is generally between 30°C and the boiling point of the organic solvent, preferably between 30°C and 80°C, more preferably between 40°C and 60°C, for example 50°C. The heating time may be the same as the mixing time, or may be longer or shorter. In general, the heating time may be between 5 minutes and 60 minutes, for example depending on the total amount of materials.
[0119] As will be readily understood by those skilled in the art, the order of steps a) and b) is important. Thus, step a) may be carried out before, after or simultaneously with step b).
[0120] In step c), the mixing of the SC with the EC and other optional ingredients can be carried out by any means in the art, such as a mixer. The other optional ingredients can include, but are not limited to, a second amount of water, a thickener, other possible surfactants, and combinations thereof. The amount of the second amount of water is determined by the first amount of water and the total amount of water. In general, the mixing time can be, for example, 5 minutes to 30 minutes depending on the total amount of materials.
[0121] In step c), the mixing of the SC with the EC and any other ingredients may be carried out under shear (e.g., 500-100000 rpm, e.g., 1000-80000 rpm, in particular 2000-40000 rpm, more particularly 12000-20000 rpm) to achieve an average particle size d90 of ≦15 μm, preferably ≦7 μm, more preferably ≦5 μm, based on all particles of all types. As described in the first embodiment, the average particle size may be measured by any conventional method in the art, e.g., a laser particle size analyzer Malvern MS3000. Shearing may be achieved by any conventional means in the art, such as high shear equipment. In general, the shearing time may be the same as or shorter than the mixing time. In general, the shearing time may be, for example, 5 minutes to 30 minutes, depending on the total amount of material and the desired particle size.
[0122] If the composition includes a thickening agent, the thickening agent may be added in step a), step c) and / or optional step d) depending on the amount of thickening agent and actual requirements. In one embodiment, if the composition includes a thickening agent, step c), i.e., mixing the SC with the EC and any other ingredients, may include c1) mixing the SC with some or all of the thickening agent to form a homogeneous suspension, and c2) mixing the suspension obtained in c1) with the EC. In this case, all remaining other optional ingredients (e.g., a second amount of water and other possible additives) except for the thickening agent may be added in c1) or c2). It is also possible to add some of the remaining other optional ingredients in c1) and others in c2). In another embodiment, if the composition includes a thickening agent, the process may further include step d): mixing the dispersion obtained in step c) with some or all of the thickening agent. The mixing step may be carried out by any means in the art, such as a mixer. Generally, the mixing time can be from 5 minutes to 60 minutes depending, for example, on the total amount of ingredients.
[0123] In this disclosure, unless otherwise specified, all specific descriptions in the first aspect also apply to the second aspect, with all relevant descriptions being reproduced herein. For example, unless otherwise specified, all specific descriptions in the first aspect for the stable agrochemical composition, the first, second and third active ingredients, their contents in the composition and their relative amounts with respect to one another, organic solvents and their contents, possible additives (thickeners, dispersants, wetting agents, emulsifiers, antifreeze agents, defoamers and bactericides) and their contents also apply to the second aspect, with all relevant descriptions being reproduced herein.
[0124] Third aspect In a third aspect, the present disclosure provides a method for producing a method for treating a cancer cell comprising: a) forming a SC of a first active ingredient; b) forming an EC of the second active ingredient and the third active ingredient; and c) Mixing the SC with the EC and any other ingredients. A process comprising: a first active ingredient that is a solid at room temperature and insoluble in water at room temperature, a second active ingredient that is a solid at room temperature, and a third active ingredient that is a liquid at room temperature; and The present invention provides a stable agrochemical composition prepared by a process, in which a first active ingredient is insoluble in a third active ingredient at room temperature, and a second active ingredient has a solubility in the third active ingredient of 1 to 33 g / 100 g at room temperature.
[0125] As described in the second aspect, it has now been found that stable agrochemical compositions comprising first and second solid active ingredients and a liquid third active ingredient, in particular stable SEs comprising these two solid active ingredients and a liquid active ingredient, can be successfully prepared by combining an EC and an SC by carefully selecting the active ingredients in each of the EC and SC, in particular when (1) the first active ingredient is insoluble in both water and the third active ingredient, and (2) the second solid active ingredient has a solubility of 1-33 g / 100 g in the liquid active ingredient at room temperature. Specifically, the present inventors have unexpectedly found that a stable agrochemical composition, particularly a stable SE, can be successfully formulated only when a suspension concentrate (SC) of a first active ingredient is mixed with an emulsifiable concentrate (EC) of a second active ingredient and a third active ingredient, particularly when the content of the oil phase (the sum of the second and third active ingredients, the organic solvent, and any optional additives used herein) is at least 30 weight percent based on the total weight of the composition, preferably at least 40 weight percent based on the total weight of the composition, preferably at least 50 weight percent based on the total weight of the composition, preferably at least 60 weight percent based on the total weight of the composition. More specifically, the present inventors have unexpectedly found that when the second active ingredient is added to the SC together with the first active ingredient, a stable agrochemical composition, particularly a stable SE, cannot be successfully formulated when the third active ingredient is formulated in any dosage form (e.g., in an EC or EW). Surprisingly, the inventors of the present disclosure have also found that when a second active ingredient is formulated together with a third active ingredient in an EW, a stable agrochemical composition, especially a stable SE, cannot be successfully formulated when a first active ingredient is formulated in an SC, especially when the content of the oil phase (the sum of the second and third active ingredients, the organic solvent and any optional additives used herein) is at least 30 weight percent based on the total weight of the composition, preferably at least 40 weight percent based on the total weight of the composition, preferably at least 50 weight percent based on the total weight of the composition, preferably at least 60 weight percent based on the total weight of the composition.
