Description

Technical Field

[0001] The present disclosure relates to an insecticidal composition, and more specifically, to a stable oil-in-water microemulsion composition containing at least one of cedarwood oil, lemongrass oil, peppermint oil, rosemary oil and sesame oil, isopropyl alcohol and water.

[0002] [Cross-reference to Related Applications] This application claims priority to U.S. Provisional Application No. 63 / 465,435, filed on May 10, 2023, entitled "Stable Oil-in-Water Microemulsion Composition". The entire disclosure of the above application is incorporated herein by reference.

Background Art

[0003] Insecticidal compositions have been used for many years to prevent pest attacks on humans, animals and crops. In recent years, consumers tend to prefer insecticidal products containing active ingredients derived from natural essential oils rather than synthetic or other pesticide-containing products including products with inert ingredients. Among insecticides containing essential oils, aqueous products generally have a mild odor compared to oily products and are less likely to leave residues or stains on the application surface, so they tend to be preferred by consumers. However, most commercially available aqueous insecticidal products require more than 5% emulsifiers, surfactants and co-surfactants, especially sodium lauryl sulfate, to form stable oil-in-water microemulsions. The use of such high concentrations of emulsifiers, surfactants and co-surfactants may cause undesirable foaming during product application.

[0020] This disclosure also describes a method for controlling pests, which includes applying a composition comprising at least one active ingredient, a total surfactant component including a main surfactant and a secondary surfactant, alcohol, a salt, and water to a surface to be treated. [Modes for carrying out the invention]

[0021] In the field of pest control, it is known that consumers demand products that have low content of synthetic insecticides and inert components, and that have high efficacy in knocking down and / or killing insects. Furthermore, it is desirable that pest control products be water-based, have a milder odor compared to oil-based products, and leave less residue on the application surface. In addition, in water-based pest control products, it is preferable to use low concentrations of emulsifiers, surfactants, and auxiliary surfactants in order to reduce undesirable foaming. This specification discloses a reversible emulsion composition for pest control comprising at least one active ingredient, a total surfactant component including a main surfactant and an auxiliary surfactant, alcohol, salt, and water.

[0022] While specific values ​​for ranges set in various embodiments are described, it should be understood that within the scope of this disclosure, the concentration of each component may vary depending on the application, and that any individual value falling within these ranges is explicitly considered herein.

[0023] One aspect of this disclosure includes an emulsion composition. An emulsion is defined as a mixed system in which two or more liquids that are not normally miscible (i.e., miscible or incompatible) separate by liquid-liquid phase separation. In some embodiments, the emulsion composition may be reversible. In this disclosure, “reversible emulsion” means that the composition has the property of undergoing a reversible phase change (emulsification and / or deemulsification). In some cases, the emulsion composition may be deemulsified at high or low temperatures, i.e., at temperatures about 10°C or more above or about 10°C or more below room temperature, or at temperatures about 20°C or more above or about 20°C or more below room temperature. A “reversible emulsion” or “stable emulsion” composition has the property of returning to a nearly transparent and homogeneous phase at room temperature with little or no physical stirring, such as stirring or shaking. In contrast, an unstable emulsion may not return to a transparent and homogeneous phase at room temperature (23°C). Furthermore, unstable emulsions may revert to a clear, homogeneous phase at room temperature only under continuous and / or strong physical stirring.

[0024] One aspect of this disclosure comprises at least one active ingredient. An active ingredient is a component that produces the intended effect of the composition. In this specification, the intended effect of the composition includes pest control by knockdown and / or insecticidal action of pests. In some embodiments, at least one active ingredient may include an essential oil. An essential oil is defined as a concentrated hydrophobic liquid containing volatile chemical compounds of plant origin. In some embodiments, at least one active ingredient may include cedarwood oil, lemongrass oil, rosemary oil, peppermint oil, sesamin oil, or any combination thereof.

[0025] In certain circumstances, the composition may contain one or more ingredients that are approved for use in minimum-risk pesticide products that are exempt from the Federal Insecticide, Fungicide, and Rodenticide Act (hereinafter referred to as "FIFRA") based on the minimum-risk exemption provisions of FIFRA (40 CFR § 152.25(f)). For example, this includes, but is not limited to, the ingredients listed in the "Active Ingredients Permitted in Minimum-Risk Pesticide Products Exempt from Registration" set forth in 40 CFR § 152.25(f).

[0026] The compositions and their active ingredients according to the present disclosure may further contain other active ingredients in addition to, or in place of, essential oils.

The concentration range of peppermint oil will vary based on the concentrations of other components of the insecticidal composition, such as the total surfactant components including the main and secondary surfactants, alcohol, salt, and water.

[0032] Another aspect of this disclosure is the total surfactant component. The total surfactant component includes a primary surfactant and a secondary surfactant. A surfactant is defined as a compound that reduces surface tension or interfacial tension between two liquids, a gas and a liquid, or a liquid and a solid.

In other embodiments, the secondary surfactant may include polyglyceryl-4-oleate, polyglyceryl oleate, decaglycerol monostearate, or any combination thereof.

[0033] To produce stable oil-in-water emulsion compositions, surfactants are typically used at concentrations exceeding 5%. This is demonstrated in U.S. Patent Nos. 10,752,785, 8,778,910, U.S. Patent Publication Nos. 2010 / 0173782, 10,980,888, 11,535,793, and 2006 / 0165739, all of which are incorporated herein by reference in their entirety. However, unexpectedly, stable emulsion compositions were obtained even when the total surfactant content was less than about 5% by weight. Even more surprisingly, stable emulsion compositions were obtained even when the total surfactant content was less than about 3% by weight. In one embodiment, the composition may contain about 2.80% to about 4.50% by weight of total surfactant components, based on the total weight of the composition. The stable emulsion compositions disclosed herein can be used in combination with a variety of active ingredients. Furthermore, the stable emulsion compositions of this disclosure have lower viscosity compared to compositions containing more than 5% surfactant, and therefore, the stable emulsion compositions of this disclosure are applicable to various delivery systems such as aerosols, trigger sprays, and mists. In addition, the low concentration of surfactant used in the stable emulsion compositions disclosed herein has the effect of suppressing foaming of the composition during use.

In some embodiments, the composition may contain at least one additive in an amount from about 1% to about 7% by weight, based on the total weight of the composition. In some embodiments, the composition may contain at least one additive in an amount from about 2% to about 5% by weight, based on the total weight of the composition. In some embodiments, the composition may contain at least one additive in an amount from about 2.5% to about 4% by weight, based on the total weight of the composition. Although specific values ​​are described in exemplary embodiments, it should be understood that within the scope of this disclosure, the concentration of at least one additive may vary depending on the application. The concentration range of at least one additive will vary based on the concentrations of other components of the composition, such as at least one active ingredient, total surfactant components including a main surfactant and a secondary surfactant, alcohol, salt, and water.

[0041] In some embodiments, the composition may contain about 60% to about 90% by weight of water based on the total weight of the composition. In some embodiments, the composition may contain about 63% to about 88% by weight of water based on the total weight of the composition. In some embodiments, the composition may contain about 65% to about 85% by weight of water based on the total weight of the composition. In some embodiments, the composition may contain about 70% to about 83% by weight of water based on the total weight of the composition. In some embodiments, the composition may contain about 75% to about 82% by weight of water based on the total weight of the composition. In exemplary embodiments, water may be present in amounts of about 81.64% by weight, about 75.77% by weight, about 78.52% by weight, about 76.02% by weight, about 77.02% by weight, or about 80.14% by weight relative to the total weight of the composition. Although certain values ​​are described in these embodiments, it should be understood that within the scope of this disclosure, the concentration of water may vary depending on the application. The concentration range of water varies based on the concentrations of other components of the composition, such as at least one active ingredient, a total surfactant component including a main surfactant and a secondary surfactant, alcohol, and salts.

[0042] Unexpectedly, it was found that a stable emulsion composition could not be formed if the main surfactant, secondary surfactant, salt, or alcohol was not present in the composition. Even more surprisingly, a stable emulsion composition was formed by adding one, two, or three active ingredients. Examples of combinations of active ingredients in a stable emulsion composition in some embodiments are as follows: i) Cedarwood oil, lemongrass oil, and sesamin oil ii) Cedarwood oil, peppermint oil, and sesamin oil iii) Cedarwood oil, rosemary oil, and sesamin oil iv) Cedarwood oil and sesamin oil v) Rosemary oil vi) Lemongrass oil and rosemary oil vii) Cedarwood Oil

[0043] Furthermore, a stable emulsion composition is formed when the weight percentage of at least one active ingredient, or the cumulative weight percentage of two or more active ingredients, is in the range of about 5.80% to about 9.00% by weight relative to the total weight of the composition.

[0044] In another aspect of this disclosure, the emulsion composition may be used for pest control. Surprisingly, the aforementioned emulsion composition has been found to exhibit knockdown or insecticidal activity (i.e., insecticidal activity) against a wide range of insects. The emulsion composition has a knockdown or killing effect against one or more pests, including flies, ants, cockroaches, spiders, mosquitoes, fruit flies, moths, or any combination thereof. In some embodiments, the emulsion composition may exhibit pest control effects against the Florida ant (Campanotus floridanus), the German cockroach (Blatella germanica), the Aedes aegypti mosquito, the house fly (Musca domestica), the chestnut tick (Rhipicephalus sanguineus), the earwig (Euborellia annulipes), the spotted silverfish (Thermobia domestica), the house ant (Monomorium pharaonic), the Argentine ant (Linepithema humile), the giant house spider (Parasteatoda tepidariorum), the American cockroach (Periplaneta americana), the yellow fruit fly (Drosophila melanogaster), the Indian meal moth (Plodia interpunctella), or any combination thereof.

[0045] In some embodiments, the emulsion composition may be applied to a person, surface, area, or animal requiring pest control.

[0046] Unexpectedly, an insecticidal composition comprising at least one active ingredient, a total surfactant component including a main surfactant and a secondary surfactant, alcohol, salt, and water was found to protect both humans and pets and provide a stable oil-in-water microemulsion effective against target insects such as ants, fleas, ticks, mosquitoes, and other pests. Furthermore, the composition is reversible; even if a phase change occurs at low and / or high temperatures, it returns to a clear, homogeneous phase at room temperature by standing or light stirring. Generally, to form a stable oil-in-water microemulsion, it is necessary to use emulsifiers or surfactants, such as sodium lauryl sulfate, at concentrations well over 5%. However, as described in this disclosure, a stable oil-in-water microemulsion was formed even with a total surfactant component (i.e., the total emulsifier / surfactant concentration as described herein) of only about 4.2%. Furthermore, the composition described in this disclosure is pH stable and exhibits equivalent efficacy against target insects. Finally, the compositions described herein are low viscosity and can be used in various delivery systems, such as aerosols, trigger sprays, and mists.

[0047] The compositions described herein provide stable oil-in-water microemulsions with high efficacy in knocking down and killing pests. In particular, the compositions described herein achieve a maximum pest knockdown rate of 100% within 30 seconds and a maximum pest mortality rate of 100% within 24 hours. In one embodiment, the composition, when measured by the method described below, has an insect knockdown rate of about 90% or more at 30 seconds and an insect mortality rate of about 100% at 24 hours. In some embodiments, the composition demonstrated an insect / arthropod knockdown rate of approximately 90% or more in 30 seconds and an insect mortality rate of approximately 100% in 24 hours against Indian meal moth, fruit fly, mosquito, carpenter ant, Argentine ant, Pharoah ant, firebrat, earwig, house fly, and German cockroach, as measured by the Insect / Arthropod Knockdown and Mortality Test. In other embodiments, the composition demonstrated an arthropod mortality rate of approximately 100% in 24 hours against cat flea, as measured by the Flea Direct Spray Test. In some embodiments, the composition, as measured by the Tick Direct Spray Test, resulted in a 24-hour arthropod mortality rate of approximately 100% against the brown dog tick. In some embodiments, the composition, as measured by the Cockroach Direct Spray Test, resulted in an insect knockdown rate of over 90% in 30 seconds against the German cockroach, a 24-hour insect mortality rate exceeding 90% against the American cockroach, and 100% against the German cockroach.In other embodiments, the composition demonstrated an insect / arthropod knockdown and mortality test result of approximately 100% insect mortality over 24 hours for Indian meal moth, housefly, fruit fly, mosquito, carpenter ant, Argentine ant, Pharaoh ant, firebrat, common house spider, earwig, and German cockroach. In further embodiments, the composition demonstrated an insect knockdown rate of approximately 90% or more in 30 seconds against Indian meal moth, fruit fly, carpenter ant, Argentine ant, Pharaoh ant, firebrat, earwig, house fly, and German cockroach, as measured by the same test.

[0048] This disclosure also describes a method of killing insects, which includes applying a reversible emulsion composition for pest control to a surface where needed. The reversible emulsion composition comprises a total surfactant component including at least one active ingredient, a main surfactant and a secondary surfactant, a salt and water. "Apply" here includes wiping, spraying, pouring, or bringing a surface into close proximity to the composition, or any other act of exposing a surface to the composition.

[0076] [Experimental Procedure] [Insect / Arthropod Knockdown and Mortality Tests] Test room: Temperature: 80±7°F (27±4℃), relative humidity: 50±20%.

[0077] Treatment containers in the test system: For ants, silverfish, and earwigs, use plastic cups with filter paper at the bottom and fitted with appropriate lids. For mosquitoes, spiders, moths, fruit flies, and houseflies, use annular plastic containers with mesh screens on both sides that are suitable for holding insects.

[0078] Test Design: For each test substance, five replicate tests were conducted with groups of 10 insects, and 35 replicate tests were conducted with groups of 1 spider. The number of knockdowns was measured at predetermined time intervals based on the test systems shown below. In all test systems, the number of deaths was measured 24 hours after treatment. The same procedure was applied to the control group. The target spray distance was approximately 12-18 inches to ensure that the insect's body surface was sufficiently wet.

[0079] Preparation: The large carpenter ants were kept in plastic containers equipped with food, water, and hiding places. Immediately before the test, individual ants were collected and placed in plastic cups by shaking them out. The Argentine ants and house ants were collected directly from their rearing trays and transferred to test cups.

[0080] Before the start of the experiment, the insects and arthropods were confirmed to be in good health and transferred to appropriate test containers. Test procedure: The inside walls of the bottles were lightly greased, and filter paper was placed at the bottom of the bottles. The target spray distance was set to approximately 12-18 inches to ensure the insects' bodies were sufficiently moistened. The test system was introduced into the spraying apparatus by placing the treatment containers one by one on the spraying apparatus's wire platform.

[0081] For ants, beetles, earwigs, and silverfish, the opening of the plastic cup was positioned facing the spray source of the test substance. For mosquitoes, flies, moths, and spiders, annular plastic containers covered on both sides with wire mesh were secured to retaining clamps, with the wire mesh side facing the spray source of the test substance.

[0082] After spraying the test substance, each test system was transferred to a glass bottle (intermediate container) lined with clean filter paper, and knockdown observation was performed. Spiders were transferred to a clean, annular plastic container covered on both sides with wire mesh. Small insects were transferred using soft tweezers, a spoon, or a paintbrush, depending on their size and species.

[0083] Observation / Knockdown Count: Knockdown refers to a state in which the test system exhibits abnormal behavior. Specifically, it refers to cases where the insect is lying on its back or side, unable to maintain a normal posture even after being returned to the correct position, and / or exhibits leg spasms or other involuntary movements seen in dying insects, but with the possibility of recovery. Knockdown observations were made at the following time intervals: Carpenter ants: 30 seconds, 3 minutes, and 5 minutes. Pharaoh ants, Argentine ants, silverfish, and earwigs: 30 seconds, 1 minute, 3 minutes, and 5 minutes. Houseflies, fruit flies, and moths: 10 seconds, 20 seconds, 30 seconds, 40 seconds, 50 seconds, 60 seconds, and 120 seconds. Mosquitoes: 10 seconds, 20 seconds, 30 seconds, 40 seconds, 50 seconds, and 60 seconds. Spiders: 30 seconds, 5 minutes, and 2 hours.

[0084] Death counts were performed 24 ± 2 hours after treatment. Death in a test system refers to insects or spiders that do not move at all when stimulated. The test was terminated when all treated test systems reached 100% death rate within 24 hours.

[0085] [Direct spray test on cockroaches] The tests were conducted in a laboratory environment with a temperature of 80±7°F (27±4°C) and a relative humidity of 50±20%. A spraying platform with a surrounding wall allowing cockroaches to move freely after spraying, a platform with a low surrounding wall to confine German cockroaches during spraying, or a platform with a high surrounding wall to confine American cockroaches were used. Grease was applied to the surrounding walls and sides of the containers of all platforms.

[0086] Test Design: For each test substance, 5 replicates were performed for German cockroaches and 10 replicates for American cockroaches, and the number of knockdowns was measured at 30 seconds, 2 minutes, and 5 minutes. After spraying, the cockroaches were released from the restraint platform by removing the enclosure wall. Mortality was measured at 24, 48, 72, and 96 ± 2 hours after treatment. The spraying distance was approximately 12 to 18 inches from the test system, and the test substance was sprayed directly into the test system.

[0087] Preparation: The inside of the holding containers (i.e., plastic cups with lids) was lightly coated with grease, and the cockroaches were exposed to carbon dioxide (CO2). Then, the cockroaches were sorted by sex, and 10 adult male German cockroaches and 5 adult male American cockroaches were placed in their respective holding cups. The cups for the American cockroaches were covered with screen-like lids.

[0088] Test Procedure: The sides of the platform enclosure wall were lightly greased, and the test platform was set up. A large enclosure wall was placed on the platform, and a suitable enclosure wall was placed on the vinyl panel in the center. The spray distance was approximately 12 to 18 inches. The weight of the test substance was measured before and after spraying to calculate the actual dose.

[0089] Before spraying the test substance, the cockroaches were moved from their holding containers to the restraint platform. Twenty seconds after spraying the test substance, the enclosure walls of the platform were lifted to allow the cockroaches to move freely on the platform.

[0090] Observation / Knockdown Measurement: Cockroach knockdown refers to a state in which a cockroach exhibits abnormal behavior, such as falling over on its back or side, is unable to maintain a normal posture, or shows involuntary movements characteristic of a dying state, such as leg spasms. Cockroach knockdown was measured at time intervals of 30 seconds, 2 minutes, and 5 minutes. After a maximum of 15 minutes, the cockroaches were transferred to a clean, greased holding container, covered with a screen-like lid, and given food and a water-soaked wick.

[0091] The classification of observation results consists of the following three categories.

[0092] Surviving cockroaches: Surviving cockroaches are individuals that show a reaction by moving when poked.

[0093] Knocked-down cockroaches: Knocked-down cockroaches are individuals that, after exposure to insecticide products, are unable to perform coordinated movements or maintain a normal posture (for example, lying on their backs with only slight leg spasms).

[0094] Dead cockroach: A dead cockroach is an individual that does not show any reaction, such as movement, even when poked.

[0095] [Direct spray test for dust mites] The test was conducted under the following conditions: temperature 80±7°F (27±4°C) and relative humidity 50±20%.

[0096] The tests were conducted in five replicates for each test substance. Mortality was measured at 24, 48, 72, and 96 ± 2 hours after treatment. Mites were reared in plastic containers equipped with water and hiding places. Prior to the tests, mites were individually collected and transferred to plastic cups.

[0097] Test Procedure: Spraying was performed targeting a distance of approximately 12 to 18 inches from the test system. The weight of the test substance was measured before and after spraying to determine the actual dose. The test system was introduced into the spray device by placing each processing container on the wire mesh platform of the spray device and positioning the opening of the plastic cup facing the direction of spraying of the test substance.

[0098] Mortality was measured at 24, 48, 72, and 96±2 hours after treatment. Mite death (mites that did not move when poked or blown on) was defined as individuals that did not move when poked or blown on.

[0099] [Flea direct spray test (Cat flea (Ctenocephalides felis))] The test was conducted under the following conditions: temperature 80±7°F (27±4°C) and relative humidity 50±20%.

[0100] The tests were conducted in four replicates for each test substance, and mortality was measured at 24, 48, 72, and 96±2 hours after treatment. The spray distance was targeted to approximately 3 inches from the top of the bucket, i.e., approximately 18 inches from the insects at the bottom.

[0101] Insect preparation: Fleas were placed in vials and exposed to carbon dioxide. Twenty fleas were counted and transferred to another vial. For each test sample, five vials containing 20 fleas each were prepared (four test samples and one control sample).

[0102] Test Procedure: The test substance was sprayed directly into the test system. The weight of the test substance was measured before and after spraying to calculate the actual dose. Immediately before spraying the test substance, the contents of the vial containing fleas were emptied into a plastic bucket. The bucket was positioned at an angle of approximately 45° to the spray source. After treatment, the bucket was removed and temporarily stored in preparation for measuring the number of deaths. One hour after treatment, a circular piece of filter paper cut to the same size as the bottom of the bucket was placed inside the bucket. To measure the number of deaths, the filter paper was lifted and gently tapped or shaken to dislodge the fleas back into the bucket.

[0103] Death determination: A dead insect is defined as an individual that does not move at all even when stimulated.

In summary, Formulations K to N demonstrate that compositions lacking any one of the main surfactant, auxiliary surfactant, alcohol, or salt form unstable emulsions that cannot form a clear, thermodynamically stable, homogeneous phase at room temperature.

[0118] Formulation K, lacking a main surfactant, separates into two heterogeneous phases. Of the two phases, the larger volume phase is cloudy white, while the smaller volume phase is located on top of it and exhibits an amber color.

[0119] Formulation L, lacking auxiliary surfactants, separates heterogeneously into two phases. Of the two phases, the larger volume phase is colorless and contains a white precipitate. The smaller volume phase is located on top of it and exhibits an amber color.

[0120] Alcohol-free formulation M separates into two heterogeneous phases. Of the two phases, the larger volume phase appears cloudy. The smaller volume phase is located on top of it and exhibits a pale amber color. A white precipitate is observed at the interface between the two phases. In addition, air bubbles are present inside and on the surface of the smaller, upper phase.

[0121] Preparation N, lacking salt, separates heterogeneously into two phases. Of the two phases, the larger volume phase is colorless and contains a white to yellow precipitate throughout. A white precipitate is observed at the interface between the two phases. The smaller volume phase is located on top of it, is amber in color, and is turbid.
