[001] This application claims the benefit of U.S. Provisional Application No. 61 / 626,037, filed on September 19, 2012. Field of the Invention
[002] This invention relates to an adjuvant composition for use in the preparation of agricultural pesticidal compositions. Background of the Invention
[003] Many pesticides used in agriculture, including insecticides, fungicides, herbicides, acaricides and plant growth regulators, are applied in the form of a liquid composition. In addition to the parasiticide, such liquid compositions generally include one or more adjuvant compounds designed to improve one or more properties of the liquid composition, such as, for example, storage stability, ease of handling and / or effectiveness of the parasiticide against target organisms.
[004] It has been admitted that diversion of pesticidal compositions applied by aerosol, that is, physical movement of droplets sprayed from the parasiticide through the air in the period of application of the aerosol to a place that is not the intended one for such application, can expose people, to wildlife and the environment to parasiticide residues that can cause health and environmental effects as well as damage to property. It is known that water soluble polymers, particularly polysaccharide polymers, such as, for example, guar gum, guar gum derivatives and poly (acrylamide) polymers, are effective as deposition aids, such as drift control and / or anti-theft agents, in agricultural compositions applied in aerosol form; see, for example, US Patent No. 5,550,224 (Hazen), US Patent No. 5,874,096 (Hazen) and US Patent No. 6,391,962 (Zerrer et al.).
[005] In many applications, a polysaccharide polymer in the form of a dry powder is added to an aqueous parasiticidal composition in the field and dissolved by mixing the composition.
[006] In some applications, it would be desirable to provide an adjuvant concentrate with a high content of water-soluble polymer that would be diluted simply to the desired end-use concentration. However, in some cases, such as those in which relatively high concentrations of water-soluble polymer and other adjuvant compounds result in an adjuvant composition that is inhomogeneous, unstable and / or difficult to handle, for example, due to the intractably high viscosity , this procedure may not be feasible and / or convenient.
[007] There is a continuing interest in concentrated adjuvant compositions that exhibit improved stability and handling properties and can be readily combined with parasiticide and diluted with water to form effective aqueous pesticidal compositions that can be aerosolized to target parasites. Summary of the Invention

As used here, the term "aqueous medium" means a single-phase liquid medium that contains no more than residual amounts of water, usually based on 100 parts by weight ("pbw") of the non-aqueous medium, no more than 0.1 pbw (parts by weight) of water.

The aqueous medium may optionally further comprise water-soluble or water-miscible components dissolved in the aqueous medium. The terminology “water miscible” as used here means miscible in all proportions with water. Suitable water-miscible organic liquids include, for example, (C1-C3) alcohols, such as methanol, ethanol, propanol, and (C1-C3) polyols, such as glycerol, ethylene glycol, propylene glycol and diethylene glycol.

[0042] As used here, the term "deviation" refers to the movement, outside the target, of droplets of a parasiticidal composition that is applied to a target parasite or the parasite's environment. Compositions applied in the form of an aerosol typically exhibit a decreasing tendency to drift with a decreasing relative amount, usually expressed as a percentage of the volume of the total volume of droplets applied in aerosol form, of small size aerosol droplets, i.e. aerosol droplets with droplet size below a certain value, usually a droplet size less than 150 micrometers (“μm”). Diversion of pesticides in aerosol form can have undesirable consequences, such as, for example, unintended contact of phytotoxic pesticides with plants not related to parasites, such as crops and ornamental plants, resulting in injury to such plants not related to parasites.
[0043] As used herein, the terminology "an amount effective as a diversion control agent" in reference to the diversion control surfactant component of the present invention means an amount of that surfactant which, when added to a certain aqueous parasiticidal composition and the aqueous parasiticidal composition combined with surfactant for diversion control is applied in the form of an aerosol, it is effective in reducing aerosol deviation from the composition applied in the form of an aerosol. In general, the ability of a certain amount of a surfactant to control diversion to reduce aerosol diversion from an aerosolized composition is assessed by applying an aerosol, under the same conditions as an aerosol, of a parasiticidal composition containing a certain amount of the surfactant for diversion control and a similar parasiticidal composition that does not contain the surfactant for diversion control and then comparing the relative amount of small size aerosol droplets exhibited by compositions applied in the form of aerosol, with a reduction in the amount of droplets of small size aerosol indicative of the ability to reduce aerosol drift from the aerosolized composition.
[0044] As used here, the term "deposition aid" means a material that, when used as an ingredient in a parasiticidal composition that is applied in aerosol form to a target, improves the deposition of the parasiticidal composition on the target and includes diversion control agents, anti-theft agents and adhesion agents; “Diversion control agent” means a material that, when used as an ingredient in a parasiticidal composition that is applied as an aerosol to a target, tends to reduce physical movement of parasiticidal aerosol droplets through the air during the application period aerosol, to a location not intended for such application; and "anti-sneak agent" means a material that, when used as an ingredient in a parasiticidal composition that is applied as an aerosol to a target, tends to reduce rebound of the aerosol droplets in the period of initial contact with the target.

Suitable organic liquids include polar organic liquids, such as hexanes, cyclohexane, benzene, toluene, chloroform, diethyl ether, polar aprotic organic liquids, such as dichloromethane, ethyl acetate, acetone, tetrahydrofuran and polar protic organic liquids, such as methanol, ethanol, propanol, glycerol, ethylene glycol, propylene glycol, diethylene glycol, poly (ethylene glycol), ethylene glycol monobutyl ether, dipropylene glycol methyl ether and ethylene glycol phenyl ether, as well as mixtures of such organic liquids.
[00102] In one embodiment, the adjuvant composition of the present invention comprises, based on 100 pbw (parts by weight) of the adjuvant composition, about 50 pbw (parts by weight), more typically about 55 pbw (parts by weight) and even more typically about 60 bp (parts by weight), about 95 bp (parts by weight), more typically about 85 bp (parts by weight) and even more typically about 75 bp (parts by weight), of the liquid medium.
[00103] Water-soluble polymers useful as deposition aids include water-soluble polysaccharide polymers and water-soluble non-polysaccharide polymers.
[00104] Water-soluble polysaccharide polymers include, for example, galactomannans as guar gums, encompassing guar gum derivatives, xanthans, polyfructoses such as levan, starches, including starch derivatives, such as amylopectin, and cellulose, including cellulose derivatives, such as methylcellulose, ethylcellulose, carboxymethylcellulose, hydroxyethylcellulose, cellulose acetate-butyrate and cellulose propionate.
[00105] Galactomannans are polysaccharides that consist mainly of mannose and galactose monosaccharides. The mannose elements form a chain consisting of many hundreds of (1,4) -β-D-mannopyranosyl residues, with α-D-galactopyranosyl residues attached to 1,6 bonds at varying distances, depending on the source plant . Naturally occurring galactomannans are available from numerous sources, including guar gum, guar gum derivatives, locust bean gum, cassia gum, fenugreek gum and tare gum. In addition, galactomannans can also be obtained by classical synthetic routes or can be obtained by chemical modification of naturally occurring galactomannans.
[00106] Guar gum refers to the mucilage found in the seed of the leguminous plant Cyamopsis tetragonolobus. The soluble fraction of water (85%) is called “guaran”, which consists of linear chains of (1,4) -β-D-mannopyranosyl units with α-D-galactopyranosyl units joined by bonds (1,6) . The ratio between D-galactose and D-mannose in the guaran fraction is about 1: 2. Guar gum in general has an average molecular weight between 2,000,000 and 5,000,000 g / mol. Guar gums with reduced molecular weight are also known, such as, for example, about 50,000 to about 2,000,000.
[00107] Guar seeds are composed of a pair of sections of flexible, non-brittle endosperm, hereinafter referred to as “guar divisions”, between which the flexible embryo (germ) is interposed. After removing the outer cover, the seeds are separated, the germ (43-47% of the seed) is removed by sieving and the divisions are crushed. The crushed divisions are reported to contain about 78-82% of the galactomannan polysaccharide and secondary amounts of some proteinaceous material, inorganic salts, water-soluble gum and cell membranes, as well as some residual coat and embryo.
[00108] Locust gum or locust bean gum is the refined endosperm of the locust bean seed, Ceratonia siliqua. The ratio of galactose to mannose for this type of gum is about 1: 4. Locust bean gum is commercially available. Cassia gum is the refined endosperm of Senna obtusifolia and has a ratio of galactose to mannose of about 1: 5. Tare gum is derived from the refined seed gum of the tare tree. The ratio of galactose to mannose is about 1: 3. Tare gum is commercially available.
[00109] Other galactomannans of interest are modified galactomannans, including polymers derived from guar gum, such as carboxymethyl guar gum, carboxymethylhydroxypropyl guar gum, cationic hydroxypropyl guar gum, hydroxyalkyl guar gum, including hydroxyethyl guar gum, hydroxypropyl guar gum and superior hydroxyalkyl guar gums, including carboxymethyl guar gum, carboxypropyl guar gum, carboxybutyl guar gum and superior carboxyalkyl guar gums, the hydroxyethylated, hydroxypropylated and carboxymethylated guaran derivatives, the carboxyethylated and hydroxyethylated carboxyethylated derivatives and hydroxypropylated and carboxymethylated derivatives of acacia gum.
[00110] Xanthans of interest are xanthan gum and xanthan gum gel. Xanthan gum is a polysaccharide gum produced by Xanthomonas campestris and contains D-glucose, D-mannose and D-glucuronic acid as the main units of hexose and also contains pyruvate and is partially acetylated.
[00111] Levano is a polyfructose comprising 5-membered rings linked via β-2,6 bonds, with branching via β-2,1 bonds. Levano exhibits a glass transition temperature of 138 ° C and is available in particulate form. At a molecular weight of 1-2 million, the diameter of the densely packed spherulitic particles is about 85 nm.
[00112] Modified celluloses are celluloses containing at least one functional group, such as a hydroxyl group, a hydroxycarboxylic group or a hydroxyalkyl group, such as, for example, hydroxymethylcellulose, hydroxyethylcelluloses, hydroxypropylcelluloses or hydroxybutylcelluloses.
[00113] Processes for preparing polysaccharide derivatives are generally known. Usually, the polysaccharide polymer is subjected to reaction, by means of hydroxy substituents of the polysaccharide polymer, with one or more derivative agents in appropriate reaction conditions to produce a polysaccharide polymer derived with the desired substituent groups. Suitable derivative reagents are commercially available and generally contain a reactive functional group, such as an epoxy group, a chlorohydrin group or an ethylenically unsaturated group, and at least one other substituent group, such as a cationic, nonionic or anionic substituent group , or a precursor of that substituent group per molecule, wherein the substituent group can be attached to the reactive functional group of the derivative agent by a divalent linking group, such as an alkylene or oxyalkylene group. Suitable cationic substituent groups include primary, secondary or tertiary amino groups or quaternary ammonium, sulfonium or phosphine groups. Suitable non-ionic substituent groups include hydroxyalkyl groups, such as hydroxypropyl groups. Suitable anionic groups include carboxyalkyl groups, such as carboxymethyl groups. The cationic, non-ionic and / or anionic substituent groups can be introduced into the polysaccharide polymer by a series of reactions or by simultaneous reactions with the respective appropriate derivative agents.
[00114] Polysaccharide can be treated with a cross-linking agent, such as, for example, borax (sodium tetraborate), which is commonly used as a processing aid in the reaction step of the guar water-splitting process to partially provide cross-linking the surface of the guar divisions and therefore reducing the amount of water absorbed by the guar divisions during processing. Other cross-linking agents, such as, for example, glyoxal or titanate compounds, are known.
[00115] In one embodiment, the polysaccharide component of the composition of the present invention is a non-derivative galactomannan polysaccharide, more typically a non-derivative guar gum.
[00116] In one embodiment, the polysaccharide is a galactomannan-derived polysaccharide that is substituted at one or more sites of the polysaccharide by a substituent group that is independently selected for each site in the group consisting of cationic substituent groups, non-ionic substituent groups anionic substituent groups.
[00117] In one embodiment, the polysaccharide component of the composition of the present invention is a derived galactomannan polysaccharide, more typically a derived guar gum. Suitable derived guar gums include, for example, hydroxypropyltrimethylammonium guar gum, hydroxypropyl-lauryldimethylammonium guar gum, hydroxypropyl-stearyldimethylammonium guar gum, hydroxypropyl guar gum, carboxymethyl guar gum, guar gum with hydroxypropyl groups. hydroxypropyltrimethylamonics, guar gum with carboxymethylhydroxypropyl groups and mixtures thereof.
[00118] The amount of derivative groups in a derived polysaccharide polymer can be characterized by the degree of substitution of the derived polysaccharide polymer or by the molar substitution of the derived polysaccharide polymer.
[00119] As used herein, the terminology "degrees of substitution" in reference to a particular type of derivative group and a given polysaccharide polymer means the number of the average number of such derivative groups attached to each monomer unit of the polysaccharide polymer. In one embodiment, the derived polysaccharide exhibits a degree of total substitution (“STD”) from about 0.001 to about 3.0, where: STD is the sum of the DS for cationic substituent groups (“DScationics”), of the DS for nonionic substituting groups (“nonionic DS”) and DS for anionic substituting groups (anionic DS ”), DScationic is from 0 to about 3, more typically from about 0.001 to about 2.0 and even more typically from 0.001 to about 1.0, non-ionic DS is 0 to 3.0, more typically from about 0.001 to about 2.5 and even more typically from 0.001 to about 1.0 and DSanionic is 0 to 3, 0, more typically from about 0.001 to about 2.0.
[00120] As used here, the terminology "molar substitution" or "ms" refers to the number of moles of derivative groups per mole of monosaccharide units of guar gum. Molar replacement can be determined by the Zeisel-GC method. The molar substitution of polysaccharide polymers useful as the water-soluble polymer component of the present invention is generally in the range of about 0.001 to about 3.
[00121] In one embodiment, the water-soluble polymer is a water-soluble non-polysaccharide polymer. Suitable water-soluble non-polysaccharide polymers include, for example, lecithin polymers, poly (alkylene oxide) polymers, such as poly (ethylene oxide) polymers and water-soluble polymers derived from ethylenically unsaturated monomers. Water-soluble polymers derived from appropriate ethylenically unsaturated monomers include water-soluble polymers derived from (meth) acrylic acid, (meth) acrylamide, 2-hydroxyethylacrylate and / or N-vinylpyrrolidone, including homopolymers of these monomers, such as poly (acid polymers) acrylic), poly (acrylamide) polymers and poly (vinylpyrrolidone) polymers, as well as copolymers of these monomers with one or more comonomers. Suitable water-soluble copolymers derived from ethylenically unsaturated monomers include water-soluble cationic polymers produced by polymerization of at least one cationic monomer, such as a diaminoalkyl (meth) acrylate or a diaminoalkyl (meth) acrylamide, or mixtures thereof, and one or more monomers non-ionic, such as acrylamide or methacrylamide. In one embodiment, the non-polysaccharide polymer exhibits an average molecular weight greater than about 1,000 g / mol, more typically greater than about 10,000 g / mol, to about 20,000,000 g / mol, more typically about 10,000. 000 g / mol.
[00122] In one embodiment, the water-soluble polymer is in the form of particles. In one embodiment, the polysaccharide polymer particles have an average initial particle size, that is, determined for dry particles before suspension in the aqueous medium, from about 5 to 200 micrometers (μm), more typically about 20 to 200 μm , as measured by light scattering, and exhibits a particle size in the aqueous medium greater than or equal to the initial particle size, that is, greater than or equal to 5 μm, more typically greater than or equal to 20 μm, with any increase from initial particle size resulting from turgor produced by partial hydration of the polysaccharide polymer in the aqueous medium.
[00123] In one embodiment, the adjuvant composition of the present invention comprises, based on 100 pbw (parts by weight) of the adjuvant composition, about 1 pbw (parts by weight), more typically about 1.5 pbw (parts per and even more typically about 2 bpw (parts by weight), about 20 bpw (parts by weight), more typically about 15 bpw (parts by weight) and even more typically about 18 bpw (parts by weight) ), of one or more of the water-soluble auxiliary deposition polymers.
[00124] In one embodiment, the composition of the present invention further comprises a thickening agent, typically dispersed in the liquid medium, in an amount effective to improve the stability of the composition at room temperature, generally imparting viscosity in the event of shear rarefaction, for provide tensile strength or to impart viscosity in the event of rarefaction by shear and tensile strength to the composition, usually in an amount, based on 100 bpw (parts by weight) of the composition of the present invention, greater than 0 to about 10 bpw (parts by weight), more typically from about 0.2 to about 5 bpw (parts by weight) and even more typically from about 0.5 to about 5 bpw (parts by weight) of the thickening agent.
[00125] In one embodiment, the thickening agent comprises one or more thickening agents selected from silica, more typically fumed silica, inorganic or colloid-forming colloidal particles, more typically clays, and synthetic polymeric thickeners.
[00126] In one embodiment the thickening agent component of the composition of the present invention comprises a fumed silica. Fumed silica is generally produced by the vapor-phase hydrolysis of a silicone compound, such as silicone tetrachloride, in a hydrogen-oxygen flame. The combustion process creates silicon dioxide molecules that condense to form particles. The particles collide with each other, unite and sediment. The result of these processes is usually a three-dimensional branched chain aggregate, usually with an average particle size of about 0.2 to 0.3 micrometers. As the aggregates cool below the melting point of silica (1710 ° C), additional collisions result in a mechanical tangle of the chains, called agglomeration.
[00127] In one embodiment, the appropriate fumed silica has a surface area by the BET method of 50-400 square meters per gram (m2 / g), more typically from about 100 m2 / g to about 400 m2 / g.
[00128] In one embodiment, the thickening agent component of the composition of the present invention comprises a fumed silica in an amount that is effective, either alone or in combination with one or more thickening agents, to impart increased viscosity to the composition, generally in an amount, based on 100 bpw (parts by weight) of the composition, greater than 0 bpw (parts by weight), more typically about 0.1 bpw (parts by weight) and even more typically about 0.5 bpw ( parts by weight), at about 10 bpw (parts by weight), more typically at about 5 bpw (parts by weight) and even more typically at about 2.5 bpw (parts by weight), of fumed silica.
[00129] In one embodiment, the composition of the present invention comprises, based on 100 bpw (parts by weight) of the composition, more than 0 to about 10 bpw (parts by weight), more typically about 0.1 to about from 0.5 bpw (parts by weight) and even more typically about 0.5 to about 2.5 bpw (parts by weight) of fumed silica.
[00130] In one embodiment, the thickening agent component of the composition of the present invention comprises an inorganic colloid-forming clay, typically aluminum silicate or magnesium silicate, typically a smectite-type clay (also known as montmorillonite), a clay-type atapulgita (also known as paligorsquita) or a mixture of them. These clay materials can be described as clays arranged in expandable layers, where the term “expandable” as used here in reference to that clay relates to the ability of the layered clay structure to expand, or expand, in contact with water.
[00131] Smectites are clays arranged in three layers. There are two distinct classes of smectite clays. In the first class of smectites, aluminum oxide is present in the molecular organization of silicate crystals, and clays have a characteristic formula of Al2 (Si2O5) 2 (OH) 2. In the second class of smectites, magnesium oxide is present in the molecular organization of silicate crystals, and clays have a characteristic formula of Mg3 (Si2O5) (OH) 2. The variation of the hydration water in the formulas above may change according to the processing to which the clay was subjected. This is not important for the use of smectite clays in the present compositions since the expandable characteristics of hydrated clays are dictated by the structure of the silicate's molecular organization. In addition, atomic substitution by iron and magnesium can occur within the molecular organization of smectite crystals, while metallic cations such as Na +, Ca + 2, as well as H +, may be present in the hydration water to provide electrical neutrality. Although the presence of iron in this clay material is preferably avoided to minimize chemical interaction between clay and optional components of the composition, such substitutions for cations in general are not of importance for the use of clays here, as the desirable physical properties of the clay, therefore, are not substantially changed.
[00132] Aluminum silicate smectite clays with expandable layers useful here are further characterized by a molecular organization of dioctahedral crystals, while magnesium silicate smectite clays with expandable layers have a molecular organization of trioctahedral crystals .
[00133] Suitable smectite clays, including, for example, montmorillonite, (bentonite), volchonscoite, nontronite, beidelite, hectorite, saponite, sauconite and vermiculite, are commercially available.
[00134] Atapulgites are clays rich in magnesium with principles of superposition of elements of the tetrahedral and octahedral cell unit different from those of smectites. An idealized composition of the atapulgite cell unit is provided as: (H2O) 4 (OH) 2Mg5Si8O2O4H2O. Atapulgite clays are commercially available.
[00135] As noted above, the clays employed in the compositions of the present invention contain cationic counterions such as protons, sodium ions, potassium ions, calcium ions, magnesium ions and the equivalent. It is customary to distinguish between clays based on a cation that is predominantly or exclusively absorbed. For example, a sodium clay is one in which the cation absorbed is predominantly sodium. These absorbed cations can become involved in exchange reactions with cations present in aqueous solutions.
[00136] Clay materials obtained commercially may comprise mixtures of several distinct mineral entities. Such mixtures of minerals are suitable for use in the present compositions. In addition, natural clays sometimes consist of particles in which unitary layers of different types of clay minerals are stacked on top of each other (inter-ratification). Such clays are called mixed layer clays, and these materials are also suitable for use here.
[00137] In one embodiment, the thickening agent component of the composition of the present invention comprises an inorganic colloid-forming clay in an amount that is effective, either alone, or in combination with one or more other thickening agents, to impart viscosity to the composition in shear rarefaction, usually in an amount, based on 100 pbw (parts by weight) of the composition, greater than 0 pbw (parts by weight), more typically about 0.1 pbw (parts by weight) and even more typically from about 0.5 bpw (parts by weight), to about 10 bpw (parts by weight), more typically at about 5 bpw (parts by weight) and even more typically at about 2.5 bpw (parts by weight), inorganic colloid-forming clay.
[00138] In one embodiment, the composition of the present invention comprises, based on 100 bpw (parts by weight) of the composition, more than 0 to about 10 bpw (parts by weight), more typically about 0.1 to about from 5 bpw (parts by weight) and even more typically about 0.5 to about 2.5 bpw (parts by weight) of inorganic colloid-forming clay. In one embodiment, the composition further comprises a polar activator, such as propylene glycol, for the thickener clay.
[00139] A fumed silica or clay-like thickening agent is generally introduced into the liquid medium and mixed to disperse the fumed silica or clay-like thickening agent in the liquid medium.
[00140] In one embodiment, the thickening agent component of the composition of the present invention comprises one or more synthetic polymeric thickeners, such as styrene-isoprene copolymers, ethylene-propylene styrene block copolymers, styrene-isobutylene copolymers, styrene-copolymers butadiene, polybutylene copolymers, polystyrene, polyethylene-propylene, methyl methacrylate, more typically one or more block copolymer thickeners, such as styrene-propylene ethyl copolymers, styrene-isoprene block copolymers and styrene copolymers, styrene copolymers. even more typically one or more hydrogenated styrene-isoprene block copolymeric thickeners.

[00142] In one embodiment, the adjuvant composition of the present invention comprises: (a) one or more first nonionic surfactants selected from the group consisting of polyalkoxylated triglyceride surfactants, sorbitan fatty acid ester surfactants and sorbitan ester surfactants - alkoxylated fatty acid, (b) (ii) one or more anionic surfactants selected from alkaryl sulfonates, (c) a liquid medium comprising one or more (C1- C3) alkyl esters of fatty acid and (d) one or more polymers water-soluble deposition aids and (e) one or more thickening agents.
[00143] In one embodiment, the adjuvant composition of the present invention comprises: (a) one or more first nonionic surfactants selected from the group consisting of fatty acid glycol ester surfactants and alkoxylated fatty alcohol surfactants, (b) ( i) one or more second nonionic surfactants selected from alkoxylated alkylarylphenolic surfactants, (b) (ii) one or more anionic surfactants selected from aliphatic glutamate surfactants, aliphatic isethionate surfactants, aliphatic taurate surfactants and aliphatic sarcosinate surfactants, (c ) a liquid medium comprising one or more (C1-C3) fatty acid alkyl esters and (d) one or more water-soluble deposition auxiliary polymers and (e) one or more thickening agents.
[00144] In one embodiment, the adjuvant composition of the present invention comprises, based on 100 bpw (parts by weight) of the adjuvant composition: about 5 bpw (parts by weight), more typically about 8 bpw (parts by weight) and even more typically about 10 bp (parts by weight), about 30 bp (parts by weight), more typically about 25 bp (parts by weight) and even more typically about 20 bp (parts by weight), a combined amount of one or more of the first non-ionic surfactants (a) and one or more of the second non-ionic surfactants (b) (i), wherein the combined amount of one or more of the first non-ionic surfactants (a) and one or more of the second nonionic surfactants (b) (i) comprises, based on 100 bpw (parts by weight) of that combined amount: (a) about 65 bpw (parts by weight), more typically about 75 pbw (parts by weight) and even more typically about 85 pbw (parts by weight), about 100 pbw (parts by weight), m typically about 98 bp (parts by weight) and even more typically about 95 bp (parts by weight), of one or more of the nonionic surfactants and (b) (i) 0 bp (parts by weight), plus typically about 2 pbw (parts by weight) and even more typically about 5 pbw (parts by weight), about 35 pbw (parts by weight), more typically about 25 pbw (parts by weight) and even more typically about 15 bpw (parts by weight) of one or more of the second non-ionic surfactants, (b) (ii) 0 bpw (parts by weight), more typically about 0.1 pbw (parts by weight) and still more typically about 0.2 pbw (parts by weight), about 2 pbw (parts by weight), more typically about 1.5 pbw (parts by weight) and even more typically about 1 pbw (parts by weight) ), of one or more of the anionic surfactants, (c) about 50 bpw (parts by weight), more typically about 55 bpw (parts by weight) and even more typically about 60 bpw (parts by weight), about of 9 5 bpw (parts by weight), more typically about 85 bpw (parts by weight) and even more typically about 75 bpw (parts by weight), of the liquid medium comprising one or more (C1-C3) alkyl esters of acid fatty, (d) about 1 pbw (parts by weight), more typically about 1.5 pbw (parts by weight) and even more typically about 2 pbw (parts by weight), at about 20 pbw (parts per weight), more typically about 15 bpw (parts by weight) and even more typically about 18 bpw (parts by weight), of one or more of the water-soluble deposition auxiliary polymers and (e) 0 bpw (parts per weight), more typically about 0.2 bpw (parts by weight) and even more typically about 0.4 bpw (parts by weight), about 10 bpw (parts by weight), more typically about 8 bpw ( parts by weight) and even more typically about 6 bpw (parts by weight) of one or more of the thickening agents. (f)
[00145] In one embodiment, the adjuvant composition of the present invention comprises (a) one or more first nonionic surfactants selected from the group consisting of polyalkoxylated triglyceride surfactants, more typically of alkyl esters of polyalkoxylated triglyceride surfactants, (b) ( ii) one or more anionic components selected from the group consisting of anionic surfactants and polyanionic polymers, more typically one or more anionic surfactants selected from aliphatic glutamate surfactants, aliphatic isethionate surfactants and aliphatic sarcosinate surfactants. (c) a liquid medium comprising one or more (C1-C3) fatty acid alkyl esters and (d) one or more water-soluble deposition auxiliary polymers and (e) one or more thickening agents.
[00146] In one embodiment, the adjuvant composition of the present invention comprises, based on 100 bpw (parts by weight) of the alternative adjuvant composition: (a) about 5 bpw (parts by weight), more typically about 10 bpw (parts by weight) and even more typically about 15 pbw (parts by weight), about 35 pbw (parts by weight), more typically about 30 pbw (parts by weight) and even more typically about 25 pbw ( parts by weight), one or more of the first nonionic surfactants, (b) (ii) more than 0 bpw (parts by weight), more typically about 0.1 pbw (parts by weight) and even more typically about 0.2 pbw (parts by weight), about 2 pbw (parts by weight), more typically about 1.5 pbw (parts by weight) and even more typically about 1 pbw (parts by weight), of a or more of anionic surfactants, (c) about 50 bpw (parts by weight), more typically about 55 bpw (parts by weight) and even more typically about 60 bpw (parts by weight) weight), about 95 bpw (parts by weight), more typically about 85 bpw (parts by weight) and even more typically about 75 bpw (parts by weight), of the liquid medium comprising one or more (C1-C3 ) fatty acid alkyl esters, (d) of about 1 bpw (parts by weight), more typically about 1.5 bpw (parts by weight) and even more typically about 2 bpw (parts by weight), about 20 bpw (parts by weight), more typically about 15 bpw (parts by weight) and even more typically about 18 bpw (parts by weight), of one or more of the water-soluble deposition auxiliary polymers, (e) more from 0 bpw (parts by weight), more typically about 0.2 bpw (parts by weight) and even more typically about 0.4 bpw (parts by weight), to about 10 bpw (parts by weight), plus typically about 8 bpw (parts by weight) and even more typically about 6 bpw (parts by weight) of one or more of the thickening agents.
[00147] In one embodiment, the present invention is directed to a method of preparing an adjuvant composition, comprising the steps of: (1) dispersion of one or more thickening agents (e), typically selected from inorganic or inorganic colloidal particles colloid, in a liquid medium (c) to form a thickened liquid medium, (2) dispersion of one or more first nonionic surfactants (a) and at least one of one or more of the second nonionic surfactants (b) (i) or one or more anionic surfactants (b) (ii) in the thickened liquid medium, (3) optionally, dispersion of one or more thickening agents (e), typically selected from thickened silica-type thickening agents, in the thickened liquid medium and (4 ) dispersion one or more of the water-soluble deposition auxiliary polymers (d) in the thickened liquid medium.
[00148] In one embodiment, step (1) comprises dispersing, under conditions of the high shear mixture, one or more thickening agents selected from inorganic or colloid-forming colloidal particles, generally a clay-type thickening agent, and optionally one or more polar activators of one or more of the thickening agents. The stability of the composition of the present invention can be influenced by the degree of shear and activation of clay-type thickeners. The clay platelets are first moistened externally under the influence of high shear that promotes platelet de-agglomeration, followed by the addition of a polar activator to the clay, to force the clay platelets to separate further. The continued application of high shear results in a completely active rheological structure.
[00149] The order of addition of the ingredients of the composition of the present invention can influence the stability of the composition. In one embodiment, a clay-type thickener and a polar activator for the clay thickener are added to the liquid medium and subjected to high shear before any surfactants are added to the composition. It is believed that a surfactant can encapsulate cells of unactivated clay platelets and inhibit activation of the clay by the polar additive and that this can compromise the dispersion of the clay and the tension of the clay gel structure.
[00150] As long as step (1) is carried out before step (2), steps (1), (2), (3), (4) can be carried out in any order. In one embodiment, the steps are conducted in order (1), (2), (3), (4) or (1), (3), (2), (4), more typically in order (1), (2), (3), (4).
[00151] In one embodiment, the ingredients of the composition of the present invention are added in the following order: liquid medium, thickener clay, polar activator for thickener clay, emulsifiers and surfactants, fillers, secondary thickeners and auxiliary deposition polymer soluble in Water.
[00152] In one embodiment, the composition of the present invention exhibits a "shear thinning" viscosity, that is, a viscosity that, within a certain shear stress variation, decreases with increasing shear stress. Two generally recognized categories of flow behavior, that is, plastic flow behavior and pseudoplastic flow behavior, each include shear thinning behavior.
[00153] In one embodiment, the composition of the present invention exhibits plastic flow behavior. As used here, the term "plastic" in reference to the flow behavior of a composition means that the composition exhibits a characteristic "breaking stress", that is, the minimum shearing force required to initiate the flow of the composition, and exhibits shear rarefaction behavior over some range of shear force above the rupture stress. A plastic composition does not exhibit flow when subjected to shear force below its rupture stress and flows when subjected to shear force greater than its rupture stress, where, in an intermediate range of shear force greater than its rupture stress, the The composition in general exhibits a non-Newtonian viscosity that decreases according to the increase in shear force, that is, shear rarefaction behavior, and, in shear forces above the intermediate range of rupture stress, the composition may exhibit a viscosity that does not vary according to shear force, that is, Newtonian flow behavior.
[00154] In one embodiment, the composition of the present invention exhibits pseudoplastic flow behavior. As used here, the term "pseudoplastic" in reference to the flow behavior of a composition means that the composition exhibits a viscosity that decreases as the shear force increases, that is, shear rarefaction behavior.
[00155] In each case, a composition with plastic or pseudoplastic rheological properties resists flow at a low shear force, but when subjected to a high shear force, such as when it is shaken in a bottle or compressed through a orifice, the composition flows and can be easily pumped, poured or otherwise disseminated from a container. In general, sedimentation or storage condition is a low shear process, with a shear rate on the order of about 10-6 reciprocal seconds (1 / s or, equivalently, s-1) to about 0.01 s- 1, and pumping or pouring is a relatively high shear process with a shear rate on the order of more than about 1 s-1, more typically from 100 s-1 to 10,000 s-1 and even more typically 100 s- 1 to 1,000 s-1.

The emulsibility of the adjuvant composition was evaluated by inverting the cylinder once and observing, after the emulsion was left to stand for 30 seconds, on whether or not the mixture formed a macroscopically uniform emulsion and whether any creaminess or free oil was present. The stability of the emulsion was then evaluated by inversion of the cylinder ten times and observation, after the emulsion had been left to stand for 24 hours, on whether or not the mixture remained in the form of a macroscopically uniform emulsion and the amount, if any, of free oil or cream that separated from the emulsion. The results are provided in Table II below.

[00192] The stability of the composition of Examples 1-4 was assessed by visual observation of samples of the composition of about 4 to 8 ounces (0.12 to 0.24 liters) each under different temperature conditions. Good stability was defined as a formulation with minimal syneresis, that is, little or no liquid separation from the thickened formulation, no particulate decantation and maintenance of characteristics and properties, such as rheological properties, of the sample. Discrete syneresis is accepted because in case of mixing the formulation becomes uniform. The stability results are provided in TABLE III below. The results showed that the composition of Example 1 exhibited good storage stability under each of the different storage conditions.

The composition of Example 1 was found to be a shear rarefaction system with high viscosity in low shear conditions and low viscosity in high shear conditions. As shown in Figure 2, the viscosity of the composition of Example 1 was relatively high under low shear conditions, which provides resistance to separation of the components of the composition, such as sedimentation of the guar gum particles, during storage, and the viscosity of this composition was relatively low in conditions of high shear, which makes the composition liable to pumping and easy to handle in conditions of high shear. A graph of the shear rate (in reciprocal seconds [1 / s]) versus shear strength (in Pascals [Pa]) for the composition of Example 1 is also shown in Figure 2. Based on the results of shear rate / strength of shear, it was found that the composition of Example 1 has a break value of 1.42 Pa. Example 5

[00202] The relative amounts of the various ingredients of the composition of Example 6 are given in TABLE VII below.

[00203] The appearance of the composition of Example 6 was evaluated at room temperature by visual inspection. The viscosity of the composition of Example 6 was determined at 2 ° C, room temperature ("RT") and 45 ° C using a Brookfield Rheometer, LV beam, at 12 rpm. The initial emulsibility, emulsion stability and dispersibility of the adjuvant composition of Example 6 were evaluated as described with respect to Examples 1 to 4. The results are provided in TABLE VIII below.

[00204] The viscosity of the composition of Example 6 was determined periodically at room temperature using Brookfield Rheometer equipped with an LV3 beam at 20 rpm for a period of about 36 days. The results are provided in Figure 5.
[00205] The stability of the composition of Example 6 was evaluated after 1, 3 and 4 weeks at -16 ° C, at room temperature ("RT"), at 4 ° C, at 45 ° C and at 54 ° C and in freeze-thaw cycle conditions as described above with respect to Examples 1-4. The results are provided in TABLE IX below.

[00206] The composition of Example 6 was subjected to rheological measurements performed on an AR-G2 voltage-controlled rheometer (TA instruments) using Cross Hatched steel plate geometry equipped with a Peltier-based temperature control. The sample temperature was maintained at 25 ° C. The sweep test at constant speed was applied. A graph of viscosity (in Pascal seconds [Pa.s]) versus shear rate (in reciprocal seconds [1 / s]) for the composition of Example 6 is shown in Figure 6. The composition of Example 6 was found to be a shear rarefaction system with high viscosity in low shear conditions and low viscosity in high shear conditions. As shown in Figure 6, the viscosity of the composition of Example 6 was relatively high under low shear conditions, which provides resistance to separation of the components of the composition, such as sedimentation of the guar gum particles, during storage, and the viscosity of this composition was relatively low in conditions of high shear, which makes the composition liable to pumping and easy to handle in conditions of high shear. A graph of the shear rate (in reciprocal seconds [1 / s]) versus shear strength (in Pascals [Pa]) for the composition of Example 6 is also shown in Figure 6. Based on the shear rate / strength of results shear, it was found that the composition of Example 6 has a break value of 1.61 Pa. Example 7-10 and Comparative Example 1
[00207] An emulsifying mixture ("Emulsifier Blend 5") comprising 85 bpw (parts by weight) of a first nonionic surfactant (a fatty acid glycol ester [olyethylene glycol monooleate, Alkamuls 400 MO, Rhodia, Inc. ]), 7 bpw (parts by weight) of a second nonionic surfactant (fatty alcohol alkoxylate [tridecyl alcohol ethoxylate (6 moles EO), Rhodasurf BC 610, Rhodia, Inc.]) and 7 bpw (parts by weight) a third nonionic surfactant (an alkarylphenol ethoxylate [tristyrylphenol ethoxylate (10 moles EO), Soprophor TS 10, Rhodia Inc.]) and 1 pbw (parts by weight) of water were prepared by mixing the surfactants with water.
[00208] The compositions of Examples 7 and 8 were prepared by mixing Emulsifier Blend 5 with a fatty acid methyl ester (seed oil, methyl soybean) in the amounts shown in TABLE X below. Each of the compositions of Examples 12 and 13 was a homogeneous liquid that remained stable for more than 1 month at room temperature.

[00209] The aqueous aerosol compositions of Examples 9 and 10 were prepared by diluting the compositions of Examples 7 and 8, respectively, in water, according to CIPAC, with 340 ppm hardness, and a pesticide-based composition of glyphosate-potassium salt (Roundup Powermax, Monsanto) was added to the mixture. The aerosol aqueous composition of Comparative Example C1 was prepared by diluting the glyphosate-potassium salt-based pesticidal composition in CIPAC water in the same manner as in Examples 7 and 8, except that in Comparative Example C1 there was no the fatty acid methyl ester / emulsifying mixture component of Examples 7 and 8. The relative amount of each component in the compositions of Examples 9 and 10 and Comparative Example C1 are summarized in TABLE XI below. The aqueous compositions thus obtained were individually sprayed through a single flat jet nozzle Teejet XR8002 at a pressure of 40 psi (275.79 kPa) in a flow-controlled hood (speed of ~ 1.6 MPH (~ 2.57 km / h) )) and the droplet size distribution was measured perpendicular to the plane of the aerosol pattern and 30 cm below the nozzle tip. A HELOS VARIO particle size analyzer (Sympatec) was used to measure droplets generated in the sprayed compositions using an R7 lens. The results for volume percentage of the fine floating droplets (droplets with size less than 150 μm, expressed as% of volume) for each composition are provided in TABLE XI below. As noted in TABLE XI, the compositions of Examples 9 and 10 individually exhibited significantly less droplet size less than 150 μm (and therefore exhibited an increase in desirable droplet volume) significantly compared to the composition of Comparative Example C1.
Examples 11-15 and Comparative Example C2
[00210] The composition of claim 11 was prepared as follows by combining the materials listed in the relative quantities indicated in TABLE XII below. A first amount of fatty acid methyl ester (methyl soybean) was introduced into a mixing vessel followed by stirring. A polar activator (propylene carbonate) was added to the stirred fatty acid methyl ester and a thickening clay (Bentone 34) was then slowly added to the stirred mixture. The fatty acid methyl ester / polar activator / thickening clay mixture was then subjected to high shear by cycling the mixture through a mill to activate the thickening clay. A second amount of fatty acid methyl ester (methyl soybean) was then added to the fatty acid methyl ester / polar activator / thickened clay mixture stirred in the mixing vessel. A first nonionic surfactant (fatty acid glycol ester [olyethylene glycol mono-oleate, Alkamuls 400 MO, Rhodia Inc.]), a second nonionic surfactant (an alkoxylated fatty alcohol [tridecyl alcohol ethoxylate (6 moles EO ), Rhodasurf BC-610, Rhodia Inc.]) and a third nonionic surfactant (an alkarylphenol ethoxylate [tristyrylphenol ethoxylate (10 moles EO), Soprophor TS-10]) were then added in series to the stirred mixture. A water-miscible organic liquid (porylene glycol) and water were then added to the stirred mixture. A fumed silica-based thickener (Aerosil R974, Evonik Industries) was then added to the stirred mixture and the resulting mixture was then circulated through a static stirrer to disperse the fumed silica-based thickener in the mixture. An anionic surfactant (76% by weight of sodium N-methyl oleyl taurate, Geropon T77, Rhodia Inc.) was then added to the stirred mixture in the mixing vessel. A water-soluble deposition auxiliary polymer (non-derivative guar gum, Jaguar 308NB, Rhodia Inc.) was then added to the stirred mixture and stirring was continued as needed to disperse the polymer.

[00211] The aqueous aerosol compositions of Examples 12-15 were prepared as follows: first, the composition of Example 11 was added to the water of the CIPAP and then the pesticidal composition of glyphosate-potassium salt (Roundup Powermax) was added to the solution. Subsequently, an aqueous solution of ammonium sulphate salt (40% ammonium sulphate in water) was added to the mixture. The aqueous aerosol composition of Comparative Example C2 was prepared by diluting the pesticidal composition of glyphosate-phosphate salt and the aqueous solution of ammonium sulphate salt in CIPAP water in the same manner as in Examples 12-15, except that in Comparative Example C2 there was no adjuvant composition of Example 11. The relative amount of each component in the compositions of Examples 12-15 and Comparative Example C2 is summarized in TABLE XIII below. The aqueous compositions thus obtained were individually sprayed through a single fixed jet nozzle XR8002 or an AIXR1 1002 Air Introduction nozzle or a turbo-reactor nozzle TT1102 (Teejet) at a pressure of 40 psi (275.79 kPa) in a hood controlled by flow (speed of ~ 1.6 MPH (~ 2.57 km / h)) and the droplet size distribution was measured perpendicular to the plane of the aerosol pattern and 30 cm below the nozzle tip. A HELOS VARIO particle size analyzer (Sympatec) was used to measure droplets generated in the sprayed compositions using an R7 lens. The amount of fine floating droplet droplets (droplets smaller than 150 μm, expressed as% by volume) for each composition is given in TABLE XIII below. As seen from the results in TABLE XIII, each of the compositions of Examples 12-15 exhibited a reduction in floating droplets (exhibited an increase in droplet volume of desirable size) significantly compared to the composition of Comparative Example C2.
