Description

FIELD OF THE INVENTION

[1] The present invention relates to the use of dibenzylidene sorbitol (DBS) or chemical derivatives of DBS as rheological modifiers useful in preparing stable formulations of agrochemical products in the form of oil dispersions (OD).

BACKGROUND AND SUMMARY OF THE INVENTION

[2] An agrochemical active ingredient, such as a herbicide, insecticide or fungicide or herbicide antidote, can rarely be applied in its original release form. Agrochemical products generally consist of two parts, an active ingredient and additional leaving or inert ingredients combined together in a composition. The combination of these two parts in the final product is carried out for two main purposes: (1) maintaining the stability of the products during storage and (2) providing an easy and effective way to use the product after dilution in a carrier such as water or oil, and spraying onto the treated area .

[3] Agrochemical compositions are typically formulated based on the needs of the customer and the physicochemical properties of the active ingredient (s), for example, the solubility of the active ingredient in water and other non-aqueous solvents. There are two main categories of compositions, solid compositions and liquid compositions. Liquid compositions include emulsifiable concentrates (EC), suspension concentrates (SC), soluble liquids (SL), flowing liquids (F) and oil dispersions (OD). Compositions in the form of EC consist of an oil-soluble active ingredient (s) dissolved in a non-aqueous solvent (s) to which emulsifying agents are added.

[4] The main components of the agricultural composition in the form of OD are a solvent or an oil phase and a dispersed solid phase. These main components may include active ingredients, petroleum oil or natural solvents, antidotes, rheological additives, emulsifiers, dispersing agents and other joint components of the composition, which contribute to giving the products the desired characteristics. Rheological additives provide the physical stability of the composition by increasing the viscosity of the liquid phase, preventing the insoluble particles of the active ingredient from precipitating from the suspension and forming a layer at the bottom of the storage vessel. This phenomenon, known as sedimentation, can lead to difficulties in the delivery and use of products if the deposited layer of particles forms a dense layer that is difficult to redisperse and resuspend. The associated physical instability of liquid compositions is called syneresis. The syneresis in the compositions in the form of OD, as a rule, is measured as the degree of clarification of the supernatant as a result of phase separation.

[5] The amount and degree of sedimentation occurring in the compositions as an OD for a long time can be measured by a fluidity test. This test is carried out by pouring in a controlled manner the composition as an OD from the container and measuring the amount of composition remaining in the container. The yield value is a percentage by weight of the material remaining in the container.

[6] The rheological additives used to control sedimentation, also known as thickening agents, anti-caking agents, viscosity modifiers or structuring agents, generally provide an increased viscosity of the composition as an OD. In addition to increasing the viscosity of the OD composition, the rheological additives have the ability to reduce shear viscosity, as a result of the fact that the gel network they form easily breaks when a small external force is applied. This decrease in shear viscosity allows the OD composition to maintain its viscosity and physical stability during rest, but allows this viscosity to quickly disappear when an external force is applied so that the product can be easily poured out or pumped out of its container, mixed with a carrier such like water, and make to the territory where necessary.

[7] The rheological additives used today in viscosity increasing products are available in a variety of forms and chemical formulations. They can be mineral or derived from minerals (e.g. organoclays, fumed silica), swellable polymers (e.g. polyamides or hydrogenated castor oils), associative thickeners that form structures on their own (e.g., EO / PO block copolymers), or they can be steric dispersing agents (for example, combined polymers such as polyvinylpyrrolidinones or polyacrylates). These rheological or structuring agents provide for a long time the stability of the product at rest or during storage.

[8] Agrochemical products generally need to be diluted and properly dispersed in water before use. An emulsifying system may be included in the composition as an OD to improve dispersion of the oil-based, water-immiscible composition in water. An emulsifying system typically includes a mixture of nonionic and anionic surfactants to even out differences in water hardness and temperature found in different places.

[9] For polar interactions, clays, organoclay, such as bentonite, hectorite or gibbsite clay, which are also known as hydrophobically modified clays, hydrogenated castor oils, castor oil derivatives, polyamides, polar, oxidized waxes and hydrophobized pyrogenic silica, can be used. as rheological additives in non-aqueous solvents. Organic sulfates are traditionally used for controlled flocculation of pigments in paints. High molecular weight polymers such as ethyl cellulose, cellulose acetate butyrate and artificial polymers such as polyacrylates, polystyrenes and polyisobutylenes can also be used to increase viscosity in organic solvents. Finally, soaps such as aluminum stearate and magnesium stearate can be used to increase viscosity.

[10] Natural clay products are typically layered silicates, which can be effective thickeners for a wide range of applications. However, in order to make them dispersible in non-aqueous solvents, the surface of the clay is usually treated with quaternary ammonium. These modified clays are known as organoclay thickeners. These highly agglomerated particles must first be wetted and then separated by shear. For this method, mixing with a high shear force is desirable.

Activators, such as alcohols, can penetrate between layers of clay and contribute to the formation of them loosely connected stacks for ease of use. A typical rheological curve for an OD composition modified with clay particles shows strong shear thinning and thixotropic behavior. With low shear, the clay structure may exhibit some decrease in fluidity. With an increase in shear rate, the shear force exerted more and more destroys the clay network, and the layered clay particles begin to move with the flow. When the shear force disappears, the clay network is restored, and the viscosity grows again. Depending on the type and origin of clay products, it is important to know that the effectiveness of the formation of rheological properties depends on differences in the size and shape of clay particles. Apparently, boehmite clay is more effective at enhancing the rheological properties of a liquid than other types of clay due to its larger aspect ratio and, therefore, larger surface area.

[11] The mechanism of thickening by hydrogenated castor oils and their derivatives, polyamides and polar, oxidized waxes is based on the formation of hydrogen bonds, but these additives may be somewhat sensitive to the action of temperature. The process of activating hydrogenated castor oil products requires mixing with shear and heat, as these products are supplied in the form of finely divided powders. Like organoclay, these finely divided powders must be dispersed into a gel form without being completely dissolved in a solvent. The first step is the swelling of the crystalline particles by means of a solvent using shear and heating to produce swollen particles that become completely separate and dispersed. The activation temperature depends on the type of solvent. Care must be taken not to exceed the activation temperature, otherwise the derivatives of castor oil will completely dissolve, lose their thickening properties and recrystallize upon cooling. Usually make a preliminary gel for easier application of these materials.

[12] The third type of rheological property modifiers requiring polar interactions to create a three-dimensional network are those based on fumed silica. Pyrogenic silica, both hydrophilic and hydrophobic, consists of nanosized particles of primary silicates bonded together to form segregates in the form of chains. Due to their extremely high surface area and compatibility with a wide range of solvents, fumed silica products are widely used in the preparation of industrial and consumer products. Although both hydrophilic and hydrophobic fumed silica can be used as thickeners in OD compositions, hydrophobic silica generally provides rheological properties that are easier to control in non-aqueous compositions compared to hydrophilic silica.

[13] The rheological additives used in the compositions in the form of OD to ensure that the suspended particles of the active ingredients are not prone to irreversible sedimentation, can be used individually or in combination with other rheological additives. Very often, one or more rheological additives are combined in one composition as an OD to obtain the desired rheological properties and, at the same time, minimize any adverse interactions that may occur between the ingredients. The appropriate selection and amount of thickening agents for OD can enhance the thickening effect and range of application of a particular composition. Factors that must be considered when choosing rheological additives to develop a stable OD system are the type of solvent, interactions with emulsifiers, the reliability of the activation of thickening agents, and the sensitivity to temperature of the resulting system.

[14] While there are many modifiers of rheological properties available for use to stabilize agrochemical compositions in the form of OD with respect to sedimentation of particles, there is a constant need for new modifiers due to the limitations of existing options, incompatibility with surfactants and the diversity in the chemistry of new active ingredients and solvents discovered and developed today. In addition, the increasing number of active ingredients included in a single composition can also be a problem for formulation. These limitations can be overcome by discovering new modifiers of rheological properties that have a new principle of action or act at lower concentrations.

[15] Dibenzylidene sorbitol (DBS; CAS 32647-67-9 and 19046-64-1) has the following structure

and is an organic molecule capable of stimulating gelation or thickening in a wide variety of organic solvents. DBS is derived from the sugar alcohol D-glucitol and benzaldehyde and sold under the trademark Millithix® 925s from Milliken Chemical. DBS has been investigated for use as a gelling agent in personal care products such as antiperspirants and cosmetics, as well as in biomedical materials and electronic devices. DBS has also found use as a brightening agent for plastics made from polyolefin (Millad® 3905). The morphological characteristics of DBS are described by D. J. Mercurio and R. J. Spontak in "Morphological Characteristics of 1,3: 2,4-Dibenzylidene Sorbitol / Poly (propylene glycol) Organogels" J. Phys. Chem. B, 105 (11), pp. 2091-2098 (2001).

[16] Two simple DBS analogs known as methyl DBS (CAS 54686 - 97-4) and dimethyl DBS (CAS 135861-56-2, Millad® 3988) are also available from Milliken Chemical, and their corresponding structures are shown below.

Recently, a new DBS type product, known as NX8000 (CAS 882073-43-0), was marketed by Milliken Chemical as a brightening agent for plastics, and its structure is shown below.

There are many other chemical analogues of DBS disclosed in the literature that have generally been used as polyolefin additives to enhance clarification and improve the aesthetic appearance of plastics, as disclosed, for example, in US Pat. No. 2007/0249850 A1, incorporated herein by reference .

[17] It has now been discovered that DBS is an effective rheological modifier for agrochemical product formulations in the form of OD and provides improved action and compatibility with the increasingly complex products being developed today. The present invention provides novel methods and compositions for preparing stable compositions of agrochemical products in the form of an OD that are suitable for controlling undesirable vegetation, insects and plant diseases, a composition of the present invention comprising a solvent, dibenzylidene sorbitol or an analogue of dibenzylidene sorbitol and an agricultural active ingredient.

Detailed description of the present invention

[18] The present invention relates to the use of dibenzylidene sorbitol or dibenzylidene sorbitol analogs as rheological additives with improved action to thicken or increase the viscosity of OD formulations containing agricultural active ingredients, to enhance the stability of such formulations, to formulations comprising at least one of dibenzylidene sorbitol and a dibenzylidene sorbitol analog; and an agricultural active ingredient.

[19] The solvent of the present invention, in General, is an organic, water-immiscible solvent and may contain one or more petroleum distillates, such as aromatic hydrocarbons derived from benzene, such as toluene, xylenes, other alkyl benzenes, etc. ., and naphthalene derivatives, aliphatic hydrocarbons such as hexane, octane, cyclohexane and the like, mineral oils of an aliphatic or isoparaffin series, and mixtures of aromatic and aliphatic hydrocarbons; halogenated aromatic or aliphatic hydrocarbons; vegetable oils, seed oils, or liquid animal fats such as soybean oil, canola oil, olive oil, castor oil, sunflower seed oil, coconut oil, corn oil, cottonseed oil, linseed oil, palm oil, peanut oil, safflower oil, sesame oil, tung oil, etc. and C ₁ -C ₆ monoesters derived from vegetable oils, seed oils or liquid animal fats; short and long chain dialkylamides, saturated and unsaturated carboxylic acids; C ₁ -C ₁₂ esters of aromatic carboxylic acids and dicarboxylic acids; and C ₁ -C ₁₂ esters of aliphatic and cycloaliphatic carboxylic acids.

[22] The DBS of the present invention is used as a rheological additive to increase viscosity in agrochemical compositions as an OD by gel formation. This helps to keep the dispersed active ingredient in the solvent in a suspended state and prevents the separation and sedimentation of the active ingredient, which can lead to instability of the composition and poor quality of the product. DBS can be dispersed and properly activated in a solvent before other components are added. The resulting mixture containing activated DBS in gel form typically exhibits good shear viscosity lowering properties. DBS may comprise, with respect to the total composition, from about 0.1 g / L to 100 g / L, preferably from about 0.1 g / L to 50 g / L.

DBS, used in combination with suitable rheological additives, can comprise from about 0.1 g / l to 100 g / l, preferably from about 0.1 g / l to 50 g / l with respect to the total composition. Suitable rheological additives used in combination with DBS may comprise from about 0.1 g / l to 200 g / l, preferably from about 0.2 g / l to 100 g / l with respect to the total composition.

[39] The insecticidal or fungicidal active ingredients of the present invention may comprise from about 1 g / l to 700 g / l, preferably from about 5 g / l to 500 g / l with respect to the total composition.

[40] Generally, it is desirable to include one or more surfactants in the compositions of the present invention. Surfactants can be anionic, cationic or nonionic in nature and can be used as emulsifiers, wetting agents, suspending agents or for other purposes. Surfactants traditionally used in the field of formulation and which can be used in the present compositions are described, inter alia, in McCutcheon's Detergents and Emulsifiers Annual, MC Publishing Corp., Ridgewood, New Jersey, 1998 and Encyclopedia of Surfactants ”, Volume I-III, Chemical Publishing Co., New York, 1980-81. Typical surface active agents include salts of alkyl sulfates, such as diethanolammonium lauryl sulfate; alkylarylsulfonate salts such as calcium dodecylbenzenesulfonate; alkylene oxide and alkyl phenol addition products, such as vinylphenol-C ₁₈ ethoxylate; alcohol and alkylene oxide addition products such as tridecyl alcohol-C ₁₆ ethoxylate; soaps such as sodium stearate; alkylnaphthalene sulfonate salts such as sodium dibutylnaphthalene sulfonate; dialkyl esters of sulfosuccinate salts, such as sodium di (2-ethylhexyl) sulfosuccinate; sorbitol esters such as sorbitol oleate; quaternary amines such as lauryltrimethylammonium chloride; polyethylene glycol fatty acid esters such as polyethylene glycol stearate; block copolymers of ethylene oxide and propylene oxide; salts of mono- and dialkyl phosphate esters; vegetable oils such as soybean oil, rapeseed oil, olive oil, castor oil, sunflower seed oil, coconut oil, corn oil, cottonseed oil, linseed oil, palm oil, peanut oil, safflower oil, sesame oil, tung oil, etc. .P.; and esters of the above vegetable oils.

[41] The composition of the present invention may optionally include one or more additional inert ingredients, such as anti-foaming agents, auxiliary agents, stabilizers, flavoring agents, binding agents, neutralizing agents, buffers, anti-corrosion additives, paints, perfumes and other traditionally used ingredients.

[42] An effective amount of the OD composition of the present invention used in typical agricultural practice depends, for example, on the type of plant, the stage of plant growth, the severity of the environmental conditions, weeds, insects or fungal pathogens to be controlled, and the conditions making. Typically, a plant in need of protection against weeds or insects, or in the fight against pathogenic diseases or their destruction, is brought into contact with a certain amount of the composition in the form of an OD diluted with a carrier such as water, which provides a concentration of from about 1 to about 40,000 ppm, preferably from about 10 to about 20,000 ppm active ingredient. Contacting may be carried out in any effective manner. For example, any exposed part of a plant, such as leaves or stems, may be sprayed with the active ingredient in admixture with a suitable amount of a solvent or carrier such as water.

[43] The above compositions of the present invention can be applied to foliage of a plant or to soil or an area close to the plant. Additionally, the compositions of the present invention can be mixed with or applied with any combination of agricultural active ingredients, such as herbicides, insecticides, bactericides, nematicides, maycicides, pesticides, thermicides, rodenticides, molluscicides, arthropodocides, fertilizers, growth regulators and pheromones.

[44] In a typical method for preparing the composition as an OD of the present invention, a DBS pre-gel is first prepared by dispersing and activating DBS in a solvent while mixing with shear and heating. After cooling to room temperature, the DBS pre-gel is added with stirring to the mixture previously formed with shear by stirring the active ingredient and any other ingredients with a solvent.

[45] An example of a stable OD composition of the present invention in which the sedimentation of a dispersed active ingredient is inhibited by DBS includes:

a) a solvent comprising from about 200 g / l to about 999 g / l of Aromatic 200ND with respect to the total composition;

b) a rheological additive comprising from about 0.1 g / l to about 100 g / l of dibenzylidene sorbitol with respect to the total composition;

c) an active ingredient in relation to the total composition, from about 1 g / l to about 200 g / l of pyroxulam;

d) optionally, other inert ingredients of the composition.

Examples

[46] In order to properly activate DBS, a 1.5% solution of DBS pre-gel in an aromatic solvent (eg, Aromatic 200 with a low naphthalene content from ExxonMobil) was prepared by dispersing 1.5 g of DBS in 98.5 g of Aromatic 200 at high shear, heating the mixture to 50-55 ° C for 15 minutes and cooling the mixture to room temperature with stirring at low shear. The resulting mixture should be translucent to transparent and exhibit strongly thixotropic properties of the gel.

[47] The compositions of the present invention shown in table 1 were obtained using the following procedure: 1) the amount of solvent shown in table 1 was placed in a glass flask equipped with a mechanical stirrer; 2) a 1.5% preliminary DBS gel was added to the flask with constant stirring; 3) then the active ingredient was added to the mixture; 4) the mixture was stirred until homogeneous and then sonicated for 10 minutes to obtain a test sample. All samples were stable to sedimentation after 24 hours at room temperature upon visual inspection.

As shown in table 2 below, samples 7 and 8 were obtained with the ingredients shown and by the following procedure. First, Aromatic 200ND was placed in a glass flask equipped with a mechanical stirrer. Then a high shear Bentone 38 powder was added to ensure complete dispersion of the powder. Then, Tensiofix N9824HT and propylene carbonate were added with constant stirring. Finally, a 1.5% DBS pre-gel was added to the mixture to obtain sample 7. No DBS was added to sample 8. Then, both samples 7 and 8 were packaged in 100 ml glass bottles to assess storage stability. Samples were stored alone at room temperature for seven months. The percentage of syneresis was measured visually in both samples, and composition 7 showed 8.7% clarification of the upper part, while composition 8 showed 57.1% of clarification of the upper part. The effect of DBS incorporation was evident in the quantitatively different phase separation in each sample.

[48] As shown in table 3 below, samples 9 and 10 were obtained with the indicated ingredients and by the following procedure. First, Aromatic 200ND was placed in a glass flask equipped with a mechanical stirrer. Then, high shear Bentone 34 powder was added to the flask to ensure complete dispersion of the powder. Then, Tensiofix surfactants and propylene carbonate were added with constant stirring. The active ingredient pyroxulam and the antidote clocvintoset-mexyl were added and completely dispersed with high shear under stirring. The rest of the ingredients were then added without any particular order, except that DBS was added as the last ingredient as a 1.5% pre-gel in Aromatic 200ND to give composition 10. Both samples were then packaged in glass bottles to assess storage stability .

[49] Samples 9 and 10 were subjected to various temperature conditions, including constant temperatures of 54 ° C and 40 ° C and one-day cycles of -10 ° C / 40 ° C, to assess their storage stability. Chemical analyzes were performed after storage for 2 weeks and found that compositions 9 and 10 were chemically stable without losing the active ingredient that was found under all storage conditions. Samples were also compared on the basis of their plastic flow stress, which, as you know, is an indicator of the strength of the rheological structure and, therefore, the stability of the compositions. The higher the stress value of the plastic flow, the more durable the gel structure and, therefore, the better the stability of the composition. Plastic flow stress was measured using an AR1000 rheometer from TA Instruments equipped with a 4 mm shaded plate. The stress-viscosity curve was obtained by applying a stationary shear force through the operation of the rheometer from the smallest possible torque on this instrument to 10,000 micro Newton meters (μN · m). Then, the stress of the plastic flow was calculated using the software on the rheometer as the initial value of the voltage, measured in pascals (Pa), at which the sample began to flow. The results of measuring the stress of plastic flow for samples 9 and 10 are shown in table 4. The results show that compositions 9 and 10 had very stable high values of stress of plastic flow, under many storage conditions, indicating that a stable rheological structure was present in each of the compositions .

[50] The fluidity of a particular composition in the form of OD is a quantitative measure of the sedimentation encountered over time and how stable the sediment is at transfusion from the container in which it is stored. The yield value can be measured by CIPAC method MT 148.1, Flowability of suspension concentrates. In this method, the suspension concentrate is left at rest for a certain period of time and then subjected to a standardized transfusion procedure. The amount of material remaining in the container after transfusion is determined and expressed as weight% of the material remaining in the container. The weight% of the material remaining after the transfusion is known as the yield value. A glass bottle containing a sample of composition 10 was left at rest at room temperature for 24 hours and then the contents of the bottle were poured according to CIPAC method MT 148.1. The residual amount of composition 10 remaining in the bottle after transfusion was 1.77 wt.% Of the initial amount, thus giving a yield value of 1.77% for composition 10.
