Description

[Technical Field]

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS This application claims priority to U.S. Provisional Patent Application No. 62 / 988,203, filed March 11, 2020, the entire contents of which are incorporated herein by reference.

[0002] The present disclosure relates to surfactants for use in agricultural products. Such surfactants may include derivatives of amino acids that have surface-active properties. [Background technology]

[0003] Surfactants (molecules with surface-active properties) are widely used in commercial agricultural formulations. These formulations may contain a variety of active agricultural agents, such as pesticides, plant growth regulators, fungicides, herbicides, and insecticides. Many such active agricultural agents may exhibit limited water solubility or be prone to crystallization. Precipitation of the active agricultural agent can result in a loss of efficacy. If the active agent becomes concentrated in the precipitate, uniform distribution is hindered upon application to the field. Therefore, surfactants may be included in the formulation to improve the solubility, wettability, and spreadability of the active agent.

[0004] The surfactants can be nonionic, zwitterionic, cationic, or anionic. In principle, any surfactant class (e.g., cationic, anionic, nonionic, amphoteric) is suitable, but it is also possible that a formulation can include a combination of two or more surfactants from two or more surfactant classes.

[0005] Surfactants are often amphiphilic molecules with a relatively water-insoluble hydrophobic "tail" group and a relatively water-soluble hydrophilic "head" group. These compounds can adsorb at interfaces, such as those between two liquids, between gas and liquid, or between solid and liquid. In systems containing a relatively polar component and a relatively non-polar component, the hydrophobic tail preferentially interacts with the relatively non-polar component, while the hydrophilic head preferentially interacts with the relatively polar component. In the case of an interface between water and oil, the hydrophilic head group preferentially extends into the water, while the hydrophobic tail preferentially extends into the oil. When added to an air-water interface, the hydrophilic head group preferentially extends into the water, while the hydrophobic tail preferentially extends into the gas. The presence of a surfactant disrupts at least some of the intermolecular interactions between water molecules, replacing at least some of the interactions with a generally weaker interaction between at least some of the water molecules and the surfactant. This results in a reduction in surface tension and may also act to stabilize the interface.

[0006] At sufficiently high concentrations, surfactants can form aggregates that act to limit the exposure of their hydrophobic tails to polar solvents. One such aggregate is a micelle. In a typical micelle, the molecules are arranged in a spherical fashion, with the surfactant's hydrophobic tail preferentially located inside the sphere and the surfactant's hydrophilic head preferentially located on the outside of the micelle, where the head preferentially interacts with more polar solvents. The effect a given compound has on surface tension and the concentration at which it forms micelles can be useful characteristics for defining a surfactant. Summary of the Invention

[0007] The present disclosure provides formulations of agricultural products such as pesticides, plant growth regulators, fungicides, herbicides, and insecticides. These products can be formulated to include one or more surfactants from one or more surfactant classes disclosed herein. The surfactants can be used as emulsifiers, wetting agents, dispersants, and / or agents that improve spreading. In addition, surfactants can be used to improve spreading. It may also be used as an adjuvant and as an agent to control spin drift.

[0008] The present disclosure provides surfactants for agricultural products in the form of derivatives of amino acids that have surface-active properties. The amino acids may be natural or synthetic amino acids, or may be obtained via ring-opening reactions of molecules such as lactams, e.g., caprolactam. The amino acids may be functionalized to form compounds with surface-active properties. Characteristically, these compounds may have a low critical micelle concentration (CMC) and / or the ability to reduce the surface tension of liquids.

DETAILED DESCRIPTION OF THE INVENTION

[0023] As used herein, the phrase "within any range using these endpoints" refers to the letters As used herein, "range" means that any range from any two of the values listed before the phrase may be selected, regardless of whether the values are toward the low end of the list or the high end of the list. For example, a pair of values may be selected from the two lower values, the two higher values, or a lower value and an upper value.

[0024] As used herein, the term "alkyl" means any saturated carbon chain, which may be straight or branched.

[0025] As used herein, the phrase "surface active" means that the associated compound is capable of lowering the surface tension of the medium in which it is at least partially dissolved and / or the interfacial tension with other phases, and thus may be at least partially adsorbed to air-liquid interfaces and / or other interfaces. The term "surfactant" may be applied to such compounds.

[0026] With respect to imprecision, the terms "about" and "approximately" may be used interchangeably and refer to a measurement that includes the stated measurement and any measurement that is reasonably close to the stated measurement. A measurement that is reasonably close to the stated measurement deviates from the stated measurement by a reasonably small amount that is understood and readily ascertained by one of ordinary skill in the relevant art. Such deviations may be attributed, for example, to measurement error or small adjustments made to optimize performance. If it is determined that a value for such a reasonably small difference would not be readily ascertained by one of ordinary skill in the relevant art, the terms "about" and "approximately" may be understood to mean plus or minus 10% of the stated value.

[0027] The present disclosure provides formulations of agricultural products such as pesticides, plant growth regulators, fungicides, insecticides, and herbicides.

[0028] I. Pesticide and plant growth regulator formulations Active agricultural agents, such as pesticides, have traditionally been provided to end users in various concentrated forms that can be diluted by the end user with water or other suitable vehicles to form ready-to-use formulations. Such concentrated forms include solid formulations, e.g., dusts, and liquid formulations. In many applications, liquid formulations are preferred because they can avoid problems such as the splashing of toxic dusts and their slow dissolution in diluents.

[0029] Liquid concentrate formulations include so-called emulsion concentrates and soluble liquid concentrates. Emulsion concentrates contain a pesticide, a water-insoluble solvent, and an emulsifier, and when added to water, they form an oil-in-water emulsion, either naturally or after mixing, in which the agricultural active ingredient is primarily present in the emulsion droplets. This type of concentrate formulation is particularly suitable for water-insoluble / low-water-soluble agricultural active ingredients, in which the recommended concentration in the ready-to-use formulation exceeds the solubility of the agricultural active ingredient.

[0030] The present disclosure provides pesticide or plant growth regulator formulations having high concentrations of agriculturally active agents that are suitable for long-term storage and delivery to end users who will ultimately treat plants by contacting the plants with agricultural formulations prepared from the concentrated pesticide formulations described herein.

[0031] The pesticide formulations of the present disclosure may include an agriculturally active agent (a pesticide or a plant growth regulator), one or more surfactants or co-surfactants selected from one or more surfactant classes, and a water-insoluble solvent.

[0032] 1. Pesticides The term "pesticide," as used herein, is known in the art and is described, at least by the U.S. Environmental Protection Agency (EPA), in the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), the Pesticide and Environmental Pesticide Control Section (7 U.S.C. § 136(u)), the Code of Federal Regulations (CFR) regarding "Protection of the Environment," and EPA regulations at 40 U.S.C. § 152.3. A pesticide is typically recognized in the art as a substance used to prevent, destroy, repel, control, and / or mitigate any pest. A pest is an organism that is harmful to humans or the environment, but does not include any endoparasites of living humans or other living animals, or any fungi, bacteria, viruses, or other microorganisms that reside on or in living humans or other living animals. In other words, the term "pest" typically does not include any organism that causes infection or disease to humans or animals. Additionally, the term "pesticides," as used herein, typically does not include any human or animal drugs or medicines, any articles that are "novel animal drugs" as defined in the art, any liquid sterilants applied to devices used inside the human body, and / or any products intended for use against fungi, bacteria, viruses, or other microorganisms in or on living humans or other living animals. Furthermore, pesticides of the present disclosure typically do not include drugs or medicines used to control disease in humans or animals (such as livestock and pets).

[0033] As used herein, the term "plant growth regulator" means a compound that, through a physiological action, accelerates or retards the rate of growth or maturation, or otherwise alters the behavior of ornamental plants or crop plants or their products.

[0051] 6.How to use The concentrated pesticide formulations of the present disclosure may be in the form of a liquid at room temperature and atmospheric pressure in which the agriculturally active ingredients are dissolved.

[0052] Concentrated pesticide formulations are intended to be mixed with an aqueous medium, typically tap water, before final use. The concentrated composition is added to the tank before, simultaneously with, or after the aqueous medium (water) is added to the tank. The concentrated pesticide composition is thereby diluted to the appropriate concentration of agricultural active ingredient.

[0053] The water content in the diluted pesticide formulation of the present disclosure may be about 75% by weight or more, about 90% by weight or more, about 99% by weight or more, or about 99.9% by weight or more, based on the total weight of the diluted composition, and ultimately depends on the amount of water required to dilute the agricultural active ingredients in the concentrated pesticide formulation of the present disclosure to the desired concentration of the ready-to-use composition.

[0054] When mixed with an aqueous medium and diluted, the agriculturally active ingredient is uniformly distributed in the aqueous medium in the form of a solution or fine emulsion, and can be substantially diluted without any crystal growth occurring.

[0055] Plants may be treated with diluted, ready-to-use pesticide formulations by contacting the plants to be treated with the diluted composition in any conventional manner. As used herein, the term "plant" refers to the stems of plants that are visible above ground level. This refers to not only the roots, leaves, and fruits, but also the roots and even the seeds. The amount of active ingredient contacted with the plant is preferably sufficient, i.e., an effective amount, for the active ingredient to exert its pesticidal or plant growth regulating activity.

[0068] 4. Carrier agent The fungicide formulations of the present disclosure may contain a carrier agent. As used herein, the term "carrier" refers to a substance, natural or synthetic, organic or inorganic, that, when combined with the active ingredient, facilitates its application to plants, seeds, or soil. Therefore, the carrier is usually inert, but at the same time, must be agriculturally acceptable, particularly for the plants to be treated. The carrier may be a solid (such as clay, natural or synthetic silicates, silicon dioxide, resins, waxes, or solid fertilizers) or a liquid (such as water, alcohol, ketone, petroleum fractions, aromatic or paraffinic hydrocarbons, chlorinated hydrocarbons, liquefied gases, etc.).

[0069] 5. Other additives Fungicide formulations may contain other additives such as stabilizers, penetrants, spreading agents, wetting agents, builders, extenders, emulsifiers, dispersants, suspending agents, plant penetrants, translocators, oils, activators, foliar nutrients, compatibilizers, shatter retardants, foam retardants, buffers, phase inversion agents, soil penetrants, stabilizers, UV filter substances, feeding stimulants, detergents, sedimentation agents, binders, liquid carriers, dry carriers such as attapulgite, kaolinite, vermiculite, starch polymers, corncob, and combinations thereof. Pesticide formulations may also contain additional chemical compounds that are not pesticides, such as activators, feeding deterrents, antifouling agents, attractants, sterilizers, disinfectants, fumigants, pheromones, repellents, defoliants, desiccants, insect growth regulators, plant growth regulators, synergists, adjuvants, and combinations thereof.

[0070] These additives may be present in the pesticide formulation, independently, in an amount of about 0% by weight or more, about 5% by weight or more, about 10% by weight or more, about 15% by weight or more, or about 20% by weight or less, about 25% by weight or less, about 30% by weight or less, or within any range using these endpoints.

[0071] 6. Fungicide emulsion Liquid fungicide formulations can be added to water or another solvent to form an agricultural emulsion at the point of sale and / or use. Typically, a well-formed agricultural emulsion is milky white, blooms (i.e., forms) naturally, and has sufficient viscosity for effective application. However, the disinfectant emulsions of the present disclosure are not limited to such parameters. They may also have other characteristics indicative of good emulsion formation.

[0072] The present disclosure provides an aqueous fungicide formulation comprising the fungicide formulation described above and water. The liquid fungicide formulation can be combined with water in a spray tank or in a separate tank before being added to the spray tank. For example, the liquid fungicide formulation can be added to a separate container and / or spray tank that contains or is separated from water. The term "diluted" refers to the fact that the agricultural liquid fungicide formulation contains water.

[0073] The water in the diluted disinfectant formulation can be present in an amount of about 5% by weight or more, about 10% by weight or more, about 20% by weight or more, about 30% by weight or more, about 40% by weight or more, about 50% by weight or more, or about 60% by weight or less, about 70% by weight or less, about 80% by weight or less, about 90% by weight or less, about 99% by weight or less, about 99.5% by weight or less, or within any range using these endpoints, of the diluted disinfectant formulation.

[0074] The disinfectant may be present in the diluted disinfectant formulation in an amount of about 0.00001% by weight or more, about 0.0001% by weight or more, about 0.0001% by weight or more, about 0.001% by weight or more, about 0.01% by weight or more, about 0.1% by weight or more, about 1% by weight or more, or about 2% by weight or less, about 4% by weight or less, about 6% by weight or less, about 8% by weight or less, about 10% by weight or less, or within any range using these endpoints.

[0075] The fungicide may be present in an amount of about 100 g / hectare or more, about 200 g / hectare or more, about 300 g / hectare or more, about 400 g / hectare or more, about 500 g / hectare or more, or about 600 g / hectare or less, about 700 g / hectare or less, about 800 g / hectare or less, about 900 g / hectare or less, about 1000 g / hectare or less, or any range using these endpoints (or the equivalent thereof).

[0076] 7. Emulsion concentrate The present disclosure provides fungicide emulsions that can be formed using emulsifiable concentrates (also known in the art as "EC"). The liquid fungicide compositions described above may or may not be EC. The emulsifiable concentrates may be liquids having a viscosity at 25°C of about 1 cps or more, 20 cps or more, 40 cps or more, 60 cps or more, 80 cps or more, 100 cps or more, or 120 cps or less, 140 cps or less, 160 cps or less, 180 cps or less, 200 cps or less, or any range using these endpoints, up to 200 cps, 50-200 cps, 100-200 cps, or about 200 cps or less. While not intending to be bound by any particular theory, it is believed that a viscosity of about 200 cps or less at 25°C promotes bloom and efficient formation of emulsions when emulsifiable concentrates are used.

[0077] The emulsion concentrate itself may be anhydrous, i.e., contain no water. Alternatively, the emulsion concentrate may contain water. The emulsion concentrate may contain water in an amount of 5% by weight or less, 2.5% by weight or less, 1% by weight or less, 0.5% by weight or less, or 0.1% by weight or less. The emulsion concentrate may contain less than 15, 14, 13, 12, 11, 10, 9, 8, 7, 6, 5, 4, 3, 2, or 1 part by weight of water per 100 parts by weight of the emulsion concentrate. The emulsion concentrate is a single oil-like phase, e.g., a hydrophobic phase, that does not contain water. As described in more detail below, when added to water or another solvent, the emulsion concentrate may bloom to form a milky white agricultural emulsion with little or no phase separation.

[0078] An emulsion concentrate may comprise a single phase. In other words, an emulsion concentrate may not comprise a distinct non-polar phase and a distinct polar phase, but instead may comprise a single phase comprising the active ingredient (fungicide), surfactant system, optional co-surfactant, and / or optional water-insoluble solvent. The single phase may comprise partial phase separation, but typically is completely separated. It should be understood that this does not include complete phase separation. At lower temperatures, phase separation may occur. The emulsion concentrate may be described as including or being the surfactant system and biocide described above (e.g., excluding optional solvents and / or optional co-surfactants).

[0079] 8. Solid dosage forms For solid compositions, powders or dispersions suitable for dusting, especially extruded Solid formulations can be formed by impregnating an active agent into a carrier powder or by granulation of a powder.

[0080] The amount of active agent in these granule compositions can be about 1% by weight or more, 10% by weight or more, 20% by weight or more, 30% by weight or more, or about 40% by weight or less, about 50% by weight or less, about 60% by weight or less, about 70% by weight or less, about 80% by weight or less, or within any range using these endpoints.

[0081] Wettable powder formulations (or spray dusts) can contain the active agent in an amount of about 20% by weight or more, about 30% by weight or more, about 40% by weight or more, or about 50% by weight or more, about 60% by weight or less, about 70% by weight or less, about 80% by weight or less, about 90% by weight or less, about 95% by weight or less, or within any range using these endpoints.

[0082] Wettable powder formulations may include a wetting agent, such as a surfactant, which may include a surfactant of the present disclosure, in an amount of about 0% by weight or more, about 1% by weight or more, about 2% by weight or more, or about 3% by weight or less, about 4% by weight or less, about 5% by weight or less, or within any range using these endpoints.

[0083] Wettable powder formulations may include a dispersing agent, such as a surfactant, which may include a surfactant of the present disclosure, in an amount of about 3% by weight or more, about 4% by weight or more, about 5% by weight or more, about 6% by weight or more, or about 7% by weight or less, about 8% by weight or less, about 9% by weight or less, or about 10% by weight or less, or within any range using these endpoints.

[0084] Wettable powder formulations may contain a solid carrier, which may include any solid carrier known in the art, in an amount of about 0% by weight or more, about 1% by weight or more, about 2% by weight or more, about 3% by weight or more, about 4% by weight or more, about 5% by weight or more, or about 6% by weight or less, about 7% by weight or less, about 8% by weight or less, about 9% by weight or less, about 10% by weight or less, or within any range using these endpoints.

[0085] Wettable powder formulations may contain one or more stabilizers and / or other additives such as pigments, colorants, penetrants, adhesion promoters, or anticaking agents.

[0086] To prepare these wettable powder formulations or spray powders, the active ingredient is intimately mixed with other ingredients in a suitable mixing device, and the resulting mixture is ground in a mill or other suitable grinding equipment.This results in spray powders that are wettable and suspendable.Therefore, they can be suspended in water at any concentration, and these suspensions are particularly useful for treating seeds.

[0087] In addition to wettable powder formulations, pastes can also be prepared. The conditions and methods for preparation and use of pastes, as well as their use, are similar to those for wettable powders or spray dusts.

[0088] Dispersible granular compositions may be prepared by agglomeration in a suitable granulating system to provide dust compositions similar to wettable powder formulations.

The herbicide formulations of the present disclosure can be applied to weeds or their locus, for example, by using conventional ground or aerial sprayers, by addition to irrigation water, and by other conventional means known to those skilled in the art.

[0115] The herbicide formulations of the present disclosure may comprise one or more herbicidal compounds having single or multiple modes of action. and can be used in suppressing undesirable vegetation in crops with single, multiple, or stacked genetic traits that confer resistance to chemicals and / or inhibitors. .

[0129] The insecticide formulation may contain an antifreeze agent in an amount, measured by weight per volume, of about 0% or more, about 1% or more, about 2% or more, about 3% or more, about 4% or more, about 5% or more, or about 6% or less, about 7% or less, about 8% or less, about 9% or less, about 10% or less, or within any range using these endpoints.

[0132] The viscosity modifier may be present in the pesticide formulation in any amount suitable to modify the viscosity to the desired level.

[0133] The insecticide formulations of the present disclosure may also include a preservative. Suitable preservatives include methylparaben.

[0134] Preservatives shall not be present in the pesticide formulation in a concentration of less than 0.0% and less than 0.1%, measured by weight per volume. It may be present in an amount above, or below, 0.2%, or within any range using these endpoints.

[0135] V. Adjuvants In addition to the uses described above, the surfactants of the present disclosure can also be used as adjuvants in the formulation of agricultural active agents such as pesticides, plant growth regulators, herbicides, fungicides and insecticides.The adjuvant compounds can be used to improve one or more properties of the formulation of agricultural active agents, such as storage stability, ease of handling, and control effect on target organisms.

[0136] VI. Spray reduction agents Spray drift refers to the unintentional dispersion of pesticides and other agricultural active agents, including off-target contamination.This can lead to human health hazards, environmental pollution, and land damage.The surfactant of the present disclosure can be used to reduce the amount of driftable fine particles of agricultural active agent formulations in both aerial and ground spray applications.

[0137] The surfactants and mixtures thereof of the present disclosure can be incorporated into aqueous spray mixtures, for example, by direct tank mixing, with a diluted formulation of an agriculturally active agent such as a pesticide, plant growth regulator, fungicide, herbicide, or insecticide.

[0138] The optimal spray droplet size depends on the application in which the composition is used. If the droplets are too large, the spray coverage will be reduced; for example, large droplets will land in certain areas, while the areas in between will receive little or no spray coverage. The maximum acceptable droplet size may depend on the amount of composition applied per unit area and the required uniformity of the spray coverage. Smaller droplets provide more uniform coverage, but are more prone to drift during spraying. Therefore, application parameters such as the uniformity of the spray coverage must be balanced against the tendency of smaller droplets to drift. For example, if the wind is particularly strong during spraying, larger droplets may be required to reduce drift, while smaller droplets may be acceptable on calmer days. In addition to the physical properties of a particular aqueous composition, the spray droplet size may also depend on the spray equipment, such as the size and configuration of the nozzle.

[0139] The reduction in spray overspray can be attributed to a variety of factors, including a reduction in the production of fine spray droplets (smallest diameter <150 μm) and an increase in the volume median diameter (VMD) of the spray droplets. In either case, for any given spray device, application, and conditions, and based on the surfactant used, the median size of multiple spray droplets produced using the surfactants described herein will be increased over the surfactant-free spray compositions of the present disclosure.

[0140] VII. Surfactants The present disclosure provides surfactants for use in agricultural products that are in the form of derivatives of amino acids. The amino acids may be natural or synthetic, or may be obtained from the ring-opening reaction of lactams such as caprolactam. The compounds of the present disclosure have been shown to have surface-active properties and can be used, for example, as surfactants and wetting agents. In particular, the present disclosure provides compounds of formula I:

[0153] [ka]

[0154] These surfactants can be synthesized by various methods. One such method involves ring-opening a lactam to obtain an amino acid having an N-terminus and a C-terminus. The N-terminus can be reacted with one or more alkylating agents and / or acids to obtain a quaternary ammonium salt. Alternatively, the N-terminus can be reacted with an oxidizing agent to obtain an amine N-oxide. The C-terminus can be reacted with an alcohol in the presence of an acid to obtain an ester.

[0155] The amino acids may be natural or synthetic, or may be derived from the ring-opening reaction of a lactam such as caprolactam. The ring-opening reaction may be acid or alkali catalyzed, an example of an acid catalyzed reaction is shown in Scheme 1 below.

[0156] [ka]

[0157] The amino acid may have as few as one or as many as 12 carbons between the N-terminus and C-terminus. The alkyl chain may be branched or straight. The alkyl chain may be interrupted by nitrogen, oxygen, or sulfur. The alkyl chain may be further substituted with one or more substituents selected from the group consisting of hydroxyl, amino, amido, sulfonyl, sulfonate, carboxyl, and carboxylate. The N-terminal nitrogen may be acylated or alkylated with one or more alkyl groups. For example, the amino acid may be 6-(dimethylamino)hexanoic acid.

[0158] Surfactant 1 can be synthesized as shown in Scheme 2 below. As shown, 6-aminohexanoic acid is treated with formaldehyde in formic acid under reflux to give 6-(dimethylamino)hexanoic acid. The free carboxylic acid is then treated with an alcohol such as dodecanol in the presence of p-toluenesulfonic acid (PTSA) in toluene to give the corresponding The ester, dodecyl 6-(dimethylamino)hexanoate, is obtained. The N-terminus is then alkylated with methyl iodide in the presence of sodium carbonate.

[0159] [ka]

[0160] Surfactant 2 can be synthesized as shown in Scheme 3 below. As shown, 6-aminohexanoic acid is treated with formaldehyde in formic acid under reflux to give 6-(dimethylamino)hexanoic acid. The free carboxylic acid is then treated with an alcohol such as dodecanol in the presence of p-toluenesulfonic acid (PTSA) in toluene to give the corresponding ester, dodecyl 6-(dimethylamino)hexanoate. The N-terminus is then oxidized with hydrogen peroxide to give the amine oxide.

[0161] [ka]

[0162] Surfactant 3 can be synthesized as shown in Scheme 4 below. As shown, 6-aminohexanoic acid is treated with formaldehyde in formic acid under reflux to give 6-(dimethylamino)hexanoic acid. The free carboxylic acid is then reacted with p-toluenesulfonyl ether in toluene to give 6-(dimethylamino)hexanoic acid. Treatment with an alcohol such as dodecanol in the presence of benzoyl sulfonic acid (PTSA) gives the corresponding ester, dodecyl 6-(dimethylamino)hexanoate. The N-terminus is then alkylated with methyl iodide in the presence of sodium carbonate.

[0163] [ka]

[0164] Surfactant 4 can be synthesized as shown in Scheme 5 below. As shown, 6-aminohexanoic acid is treated with formaldehyde in formic acid at reflux to give 6-(dimethylamino)hexanoic acid. The free carboxylic acid is then treated with an alcohol such as dodecanol in the presence of p-toluenesulfonic acid (PTSA) in toluene to give the corresponding ester, dodecyl 6-(dimethylamino)hexanoate. The N-terminus is then treated with 1,4-butanesultone in ethyl acetate at reflux to give the desired sulfonate.

[0165] [ka]

[0166] Surfactant 5 can be synthesized as shown in Scheme 6 below. As shown, 6-aminohexanoic acid is treated with an alcohol in the presence of p-toluenesulfonic acid (PTSA) in toluene to give the corresponding ester, dodecyl 6-aminohexanoate. The N-terminus is protonated with hydrochloric acid to give the desired hydrochloride salt.

[0167] [ka]

[0168] The compounds of the present disclosure exhibit surface active properties. These properties can be measured and expressed by various methods. One way to express surfactants is by the critical micelle concentration (CMC) of the molecule. CMC can be defined as the concentration of surfactant that forms micelles, and at a higher concentration, all additional surfactants are incorporated into the micelles.

[0169] As surfactant concentration increases, surface tension decreases. When the surface is completely covered with surfactant molecules, micelles begin to form. This point represents the CMC, or minimum surface tension. Adding more surfactant does not further affect the surface tension. The CMC can therefore be measured by observing the change in surface tension as a function of surfactant concentration. One such method for measuring this value is the Wilhelmy plate method. A Wilhelmy plate is typically a thin iridium-platinum plate attached to a balance by wires and positioned perpendicular to the air-liquid interface. The balance is used to measure the force exerted on the plate by wetting. This value is then used to calculate the surface tension (γ) according to Equation 1: Equation 1: γ = F / l cosθ where l is equal to the wetted perimeter (2w+2d, where w and d are the thickness and width of the plate, respectively), and for cosθ, the contact angle between the liquid and the plate is assumed to be 0 in the absence of an existing literature value.

[0170] Another parameter used to evaluate the performance of surfactants is dynamic surface tension. Dynamic surface tension is the value of the surface tension of a particular surface or interface over time. For liquids to which surfactants have been added, this may differ from the equilibrium value. Immediately after the surface is created, the surface tension is equal to that of the pure liquid. As mentioned above, surfactants reduce surface tension, so the surface tension decreases until it reaches an equilibrium value. The time required to reach equilibrium depends on the diffusion and adsorption rates of the surfactant.

[0171] One method for measuring dynamic surface tension is with a maximum bubble pressure tensiometer. This device measures the maximum internal pressure of a bubble formed in a liquid by a capillary. The measured value corresponds to the surface tension at a specific surface elapsed time, which is the time from the start of bubble formation to the maximum pressure. The dependence of surface tension on surface elapsed time can be measured by varying the rate at which the bubbles are generated.

[0172] Surface-active compounds can also be evaluated by their ability to wet on solid substrates, as measured by contact angle. When a liquid droplet contacts a solid surface in a third medium, such as air, a three-phase line is formed between the liquid, the gas, and the solid. The angle between the surface and the unit vector of surface tension, which is tangent to the droplet and plays a role in the three-phase line, is expressed as the contact angle. The contact angle (also known as the wetting angle) is a measure of the wettability of a solid by a liquid. In complete wetting, the liquid spreads completely on the solid, and the contact angle is 0°. Wetting properties are typically measured at concentrations between 1 and 100 x CMC for a given compound, but since it is not a concentration-dependent property, measurements of wetting properties may be measured at higher or lower concentrations.

[0173] In one method, an optical contact angle goniometer can be used to measure contact angles. This instrument uses a digital camera and software to determine the contact angle by analyzing the contour shape of a sedentary drop of liquid on a surface.

[0174] Potential applications for the surface-active compounds of the present disclosure include formulations for use as shampoos, hair conditioners, detergents, spot-free rinse solutions, floor and carpet cleaners, cleaners for graffiti removal, wetting agents for crop protection, adjuvants for crop protection, and wetting agents for aerosol spray coatings.

[0175] Those skilled in the art will appreciate that small differences between compounds can lead to significantly different surfactant properties, and therefore different compounds may be used with different substrates in different applications.

[0176] The following non-limiting examples are provided to illustrate the different properties of different surfactants. Table 1 below associates surfactant abbreviations with their corresponding chemical structures.

[0177] [Table 1]

[0178] Each of the five compounds is effective as a surfactant and is useful as a wetting or foaming agent, dispersing agent, emulsifier, and detergent, among other uses.

[0179] Surfactant 1, Surfactant 3, and Surfactant 5 are cationic. These surfactants are useful in both the applications mentioned above and in some further specialty applications, such as surface treatments, personal hair care products, and can also be used to create water-repellent surfaces.

[0180] Surfactant 4 is non-ionic and can be used in shampoos, detergents, hard surface cleaners, and a variety of other surface cleaning formulations.

[0181] Surfactant 5 is zwitterionic. These surfactants are useful as co-surfactants in all of the applications mentioned above.

[0182] Example Nuclear magnetic resonance (NMR) spectroscopy was performed on a Bruker 500 MHz spectrometer. The critical micelle concentration (CMC) was determined by the Wilhelmy plate method using a tensiometer (DCAT 11, DataPhysics Instruments GmbH) equipped with a Pt-Ir plate. The dynamic surface tension was determined at 23°C using a maximum bubble pressure tensiometer (Kruss BP100, Kruss GmbH). The contact angle was determined using an optical contact angle goniometer (OCA 15 Pro, DataPhysics GmbH) equipped with a digital camera.

[0183] Example 1a: Synthesis of 6-(dodecyloxy)-N,N,N-trimethyl-6-oxohexane-1-aminium iodide (surfactant 1) 6-(Dimethylamino)hexanoic acid (11.99 g, 75.36 mmol) was dissolved in toluene (50 mL) in a round-bottom flask equipped with a Dean-Stark trap. Next, dodecanol (12.68 g, 75.36 mmol) and p-toluenesulfonic acid monohydrate (PTSA) (14.33 g, 75.36 mmol) were added. The reaction was heated to reflux for 24 hours until no water was observed in the Dean-Stark trap. The solvent was removed under vacuum, and the resulting solid was washed with hexane. The solid was dissolved in dichloromethane (200 mL) and washed with saturated sodium carbonate to give dodecyl 6-(dimethylamino)hexanoate in 51% yield. 1H NMR(DMSO)δ 4.00(t,J=6.5Hz,2H),2.27(t,J=7.3Hz,2H),2.13-2.16(m,2H),2.01(s,6H),1.54-1.53(m,6H),1.27-1.18(m,20H),0.86(t,3H).

[0184] Dodecyl 6-(dimethylamino)hexanoate (1.0 g, 3.05 mmol) was dissolved in acetonitrile (10 mL). Sodium carbonate (0.388 g, 3.66 mmol) was then added, and the reaction was stirred at room temperature for 10 minutes. Methyl iodide (0.57 mL, 9.16 mmol) was added, and the reaction mixture was heated to 40° C. for 24 hours and then cooled to room temperature. The mixture was filtered and concentrated to give 6-(dodecyloxy)-N,N,N-trimethyl-6-oxohexan-1-aminium iodide as a yellow solid in 92% yield. 1 H NMR(DMSO)δ 4.00(t,J=6.7Hz,2H),3.30-3.22(m,2H),3.04(s,9H),2.34(t,J=7.4Hz,2H),1 .70-1.63(m,2H),1.62-1.46(m,4H),1.31-1.20(m,20H),0.86(t,J=6.9Hz,3H).

[0185] Example 1b: Identification of the critical micelle concentration (CMC) of surfactant 1 The critical micelle concentration (CMC) was determined. From the change in surface tension with concentration in water, the CMC was determined to be approximately 1 mmol. The plateau value of the minimum surface tension achievable with this surfactant is approximately 33 mN / m, i.e., 33 mN / m ± 3.3 mN / m. Figure 1 is a plot of these results, showing surface tension versus concentration. The plot shows that the surface tension is approximately 34 mN / m at the CMC and approximately 33.8 mN / m at concentrations above 1.0 mmol.

[0186] Example 1c: Determining the dynamic surface tension of surfactant 1 Dynamic surface tension was determined with a maximum bubble pressure tensiometer, which measures the change in surface tension of a newly created air-water interface over time. Figure 2 presents a plot of the results as surface tension versus time, showing that over the time interval from 1 ms to 75 ms, the surface tension rapidly decreases from approximately 55.5 mN / m to approximately 39.9 mN / m. Over the time interval from 75 ms to 50,410 ms, the surface tension decreases more slowly from approximately 39.9 mN / m to approximately 34 mN / m, asymptotically approaching the saturated value of surface tension at the CMC.

[0187] Example 1d: Identification of the wetting properties of surfactant 1 In addition to surface tension and surface kinetics, the wetting properties of the compounds were tested on various surfaces. For example, hydrophobic substrates such as polyethylene-HD exhibit surface wetting with a contact angle of 32°. On oleophobic and hydrophobic substrates such as Teflon®, the measured contact angle was 67.1°, much lower than that of water (Table 2).

[0188] [Table 2]

[0189] Example 2a: Synthesis of dodecyl 6-(dimethylamino)hexanoate N-oxide (surfactant 2) 6-(Dimethylamino)hexanoic acid (11.99 g, 75.36 mmol) was dissolved in toluene (50 mL) in a round-bottom flask equipped with a Dean-Stark trap. Next, dodecanol (12.68 g, 75.36 mmol) and p-toluenesulfonic acid monohydrate (PTSA) (14.33 g, 75.36 mmol) were added. The reaction was heated to reflux for 24 hours until no water was observed in the Dean-Stark trap. The solvent was removed under vacuum, and the resulting solid was washed with hexane. The solid was dissolved in dichloromethane (200 mL) and washed with saturated sodium carbonate to give dodecyl 6-(dimethylamino)hexanoate in 51% yield. 1H NMR(DMSO)δ 4.00(t,J=6.5Hz,2H),2.27(t,J=7.3Hz,2H),2.13-2.16(m,2H),2.01(s,6H),1.54-1.53(m,6H),1.27-1.18(m,20H),0.86(t,3H).

[0190] Dodecyl 6-(dimethylamino)hexanoate (1.0 g, 3.05 mmol) was dissolved in distilled water (80 mL). Hydrogen peroxide (50% solution, 1.04 g, 30.5 mmol) was added. The reaction was heated to reflux for 12 hours, and then the solvent was removed in vacuo. The resulting solid was washed with acetone to give the desired N-oxide in 90% yield. 1 H NMR(500MHz,DMSO)δ 4.00(t,J=6.6Hz,2H),3.30-3.26(m,2H),3.18(s,6H),2.31(t,J=7.4Hz,2H),1 .76-1.73(m,2H),1.54-1.57(m,4H),1.30-1.24(m,22H),0.86(t,J=6.9Hz,3H).

[0191] Example 2b: Identification of the critical micelle concentration (CMC) of surfactant 2 The critical micelle concentration (CMC) was determined. From the change in surface tension with concentration in water, the CMC was determined to be approximately 0.08 mmol. The plateau value of the minimum surface tension achievable with this surfactant is approximately 28 mN / m, i.e., 28 mN / m ± 2.8 mN / m. Figure 3 is a plot of these results, showing surface tension versus concentration. The resulting plot indicates that the surface tension at the CMC is approximately 30 mN / m or less. The plot further indicates that at concentrations of 0.08 mmol or greater, the surface tension is 30 mN / m or less.

[0192] Example 2c: Determining the dynamic surface tension of surfactant 2 Dynamic surface tension was determined using a maximum bubble pressure tensiometer, which measures the change in surface tension of a newly created air-water interface over time. Figure 4 shows a plot of surface tension versus time, showing that the compound fully saturated the surface in approximately 7.6 seconds. As can be seen from the plot, the dynamic surface tension is below 40 mN / m for surface dwell times of over 4900 ms.

[0193] Example 2d: Identification of the wetting properties of surfactant 2 In addition to surface tension and surface kinetics, the wetting properties of the compounds were tested on various surfaces. For example, hydrophobic substrates such as polyethylene-HD exhibit surface wetting with a contact angle of 39.3°, which is significantly lower than that of water. On oleophobic and hydrophobic substrates such as Teflon, the measured contact angle was 57.4°, significantly lower than that of water (Table 3).

[0194] [Table 3]

Next, dodecanol (12.68 g, 75.36 mmol) and p-toluenesulfonic acid monohydrate (PTSA) (14.33 g, 75.36 mmol) were added. The reaction was heated to reflux for 24 hours until no water was observed in the Dean-Stark trap. The solvent was removed under vacuum, and the resulting solid was washed with hexane. The solid was dissolved in dichloromethane (200 mL) and washed with saturated sodium carbonate to give dodecyl 6-(dimethylamino)hexanoate in 51% yield. 1H NMR(DMSO)δ 4.00(t,J=6.5Hz,2H),2.27(t,J=7.3Hz,2H),2.13-2.16(m,2H),2.01(s,6H),1.54-1.53(m,6H),1.27-1.18(m,20H),0.86(t,3H).

[0197] Example 3b: Identification of the critical micelle concentration (CMC) of surfactant 3 The critical micelle concentration (CMC) was determined. From the change in surface tension with concentration in water, the CMC was determined to be approximately 1.4 mmol. The minimum surface tension plateau achievable with this surfactant is approximately 30 mN / m, i.e., 30 mN / m ± 3 mN / m. Figure 5 is a plot of these results, showing surface tension versus concentration. The resulting plot shows that the surface tension at the CMC is approximately 30 mN / m or less. The plot also shows that at concentrations of 2.7 mmol or greater, the surface tension is 33 mN / m or less.

[0198] Example 3c: Determining the dynamic surface tension of surfactant 3 Dynamic surface tension was determined using a maximum bubble pressure tensiometer, which measures the change in surface tension over time at a newly created air-water interface. Figure 6 shows a plot of surface tension versus time, showing that over the time interval of 1 to 100 ms, the surface tension rapidly decreases from approximately 50 mN / m to approximately 40 mN / m. Over the time interval of 100 to 50,000 ms, the surface tension decreases more slowly from 40 mN / m to approximately 34 mN / m, asymptotically approaching the saturated value of surface tension at the CMC.

The plateau value of the minimum surface tension achievable with this surfactant is approximately 38 mN / m, i.e., 38 mN / m ± 3.8 mN / m. Figure 7 is a plot of these results, showing surface tension versus concentration. The resulting plot shows that the surface tension is approximately 38 mN / m at the CMC, and at concentrations of 1 mmol or greater, the surface tension is 37 mN / m or less.

[0204] Example 4c: Determining the dynamic surface tension of surfactant 4 Dynamic surface tension was determined using a maximum bubble pressure tensiometer, which measures the change in surface tension of a newly created air-water interface over time.
