Description

Spray composition for arthropod control

[0001] The present invention relates to a spray composition for controlling arthropods.

[0002] Among arthropods such as insects, flying pests such as mosquitoes and flies transmit pathogens to humans and other animals, causing infectious diseases and dermatitis. In particular, some mosquitoes are extremely harmful insects from a hygienic standpoint because they transmit pathogens such as dengue fever, Zika fever, yellow fever, encephalitis, and malaria. Furthermore, harmful arthropods also include agricultural pests that cause damage to agricultural crops.

[0003] Spray-type pesticides are known as pesticides for controlling these pests. For example, Patent Document 1 describes that a spray composition containing a benzoate ester, a nonionic surfactant, alcohol, and water to form a homogeneous phase can be sprayed with a uniform composition and is less likely to cause choking to the user.

[0004] (Patent Document 1) JP 2020-94106 A

[0005] The present invention relates to the following: [1] A spray composition for arthropod control, comprising component (A): a nonionic surfactant, component (B): a preservative, component (C): a thickener, and component (D): water. [2] A spray for arthropod control, comprising filling a spray container or a spray device with the spray composition according to [1]. [3] A method for controlling arthropods, comprising a step of contacting arthropods with the spray composition of [1]. [4] Use of a composition comprising component (A): a nonionic surfactant, component (B): a preservative, component (C): a thickener, and component (D): water as a spray composition for arthropod control.

[0007] However, the spray composition disclosed in Patent Document 1 still leaves room for improvement in terms of good spray characteristics, such as spraying the composition evenly and uniformly over a wide area to effectively capture and control arthropods, thereby enabling droplets of the composition to properly reach arthropods. The present invention relates to the provision of a spray composition for arthropod control that reduces discomfort during use, has excellent spray uniformity, and can be sprayed over a wide area, allowing spray droplets to properly reach arthropods present in a wide area.

[0008] The present inventors have discovered that the above problems can be solved by a composition containing a nonionic surfactant, a preservative, a thickener, and water.

[0009] According to the present invention, it is possible to provide a spray composition for arthropod control that reduces discomfort during use, has excellent spray uniformity, and can be sprayed over a wide area, thereby allowing spray droplets to reach arthropods present over a wide area appropriately.

[0010] [Definitions] As used herein, the term "arthropod control composition" refers to a composition that can be applied to the body surface of arthropods to reduce their mobility, thereby preventing and reducing damage caused by arthropods. Arthropods are described below. The term "spray composition" refers to a composition that is filled into a spray container or spray device to prepare a spray and then sprayed onto a target. The term "discomfort during use of the spray composition" refers to the irritation felt by the user in the nose or throat when inhaling the spray composition during spraying. The term "excellent spray uniformity" refers to the ability to spray the spray composition evenly over a vertical wall, leaving a substantially circular spray mark on the wall without uneven spray or gaps. The term "capable of being sprayed over a wide area" refers to the ability to spray the spray composition over a large area when sprayed from a certain distance toward a vertical wall. The term "allowing spray droplets to reach arthropods appropriately" refers to the ability to efficiently allow spray droplets of the spray composition to reach the target arthropods. The reach of spray droplets to arthropods and the resulting arthropod control effect can be evaluated, for example, by the ability of mosquitoes to fall off when the spray composition is sprayed. The discomfort felt when using the spray composition, the uniformity of spraying, the spray area, and the ability of mosquitoes to fall off can be specifically evaluated by the methods described in the Examples.

[0011] [Spray composition for controlling arthropods] The arthropod control spray composition of the present invention (hereinafter also simply referred to as the "(spray) composition of the present invention") contains component (A): a nonionic surfactant, component (B): a preservative, component (C): a thickener, and component (D): water. By having the above-mentioned configuration, the spray composition of the present invention can suppress discomfort during use. Furthermore, since it has excellent spray uniformity and can be sprayed over a wide area, droplets of the composition can be directed appropriately to arthropods, and as a result, arthropods present over a wide area can be controlled.

[0012] The reason why the composition of the present invention exhibits the above-mentioned effects is unclear, but is thought to be as follows. The composition of the present invention contains component (A): a nonionic surfactant as an active ingredient for arthropod control. Furthermore, since the composition of the present invention further contains component (D), water, as a solvent for component (A), component (B), a preservative is added to improve the storage stability of the aqueous composition. However, the present inventors have discovered that when a composition containing both components (A) and (B) is sprayed, users inhale and experience irritation in the nose and throat. One reason for this is thought to be that component (A), the active ingredient for arthropod control, reduces the surface tension of the composition. Specifically, when a low-surface-tension spray composition is discharged from the nozzle of a spray container or spray device, a swirling flow is generated near the nozzle, breaking the mist into smaller particles. The more the mist is broken up, the more easily it diffuses, and because the mist contains component (B), users who inhale the mist may experience discomfort.

[0013] Here, the spray composition of the present invention contains a thickener as component (C). It is believed that the inclusion of a thickener in the composition improves the viscosity of the composition, controls the size of the spray droplets, and prevents excessive fragmentation and diffusion of the mist near the nozzle of the spray container or spray device. Since the spray droplets of a spray composition containing component (C) are larger than those not containing component (C), the spray droplets are less likely to diffuse during spraying, and a higher proportion of them are sprayed straight from the nozzle, achieving good spray uniformity while maintaining a certain degree of spray range. As a result, it is believed that good reach of the spray droplets to arthropods can be achieved.

[0014] The term "arthropods" as used herein primarily refers to arthropods that are harmful to humans, livestock, their living spaces, and agricultural or horticultural plants. Arthropods include insects, crustaceans, spiders, centipedes, etc., and are typically insects.

[0015] Specific examples of arthropods include mosquitoes, black flies, flies, horseflies, midges, bees, cockroaches, ants, pill bugs, spiders, millipedes, centipedes, house centipedes, and larvae (caterpillars) of the order Lepidoptera, as well as agricultural pests such as grasshoppers, locusts, planthoppers, moths, stink bugs, thrips, cucumber beetles, and aphids.

[0016] The components contained in the spray composition of the present invention are described below. <Component (A): Nonionic Surfactant> Component (A) acts as an active ingredient for arthropod control. From the viewpoint of spraying the composition of the present invention on arthropods to control them, the nonionic surfactant used as component (A) is preferably a nonionic surfactant with low surface tension. Specifically, component (A) is a nonionic surfactant whose surface tension at 25°C of a 3 mmol / kg aqueous solution is preferably 27 mN / m or more and 50 mN / m or less. From the viewpoint of improving the spray uniformity and spray area of ​​the composition, the surface tension of a 3 mmol / kg aqueous solution of component (A) at 25°C is preferably 27.5 mN / m or more, more preferably 28 mN / m or more. Furthermore, from the viewpoint of improving arthropod control, the surface tension is preferably 45 mN / m or less, more preferably 40 mN / m or less, even more preferably 33 mN / m or less, and even more preferably 31 mN / m or less. The surface tension of a 3 mmol / kg aqueous solution of component (A) at 25°C is preferably 27 mN / m or more and 45 mN / m or less, more preferably 27.5 mN / m or more and 40 mN / m or less, even more preferably 28 mN / m or more and 33 mN / m or less, and still more preferably 28 mN / m or more and 31 mN / m or less.

[0017] The surface tension is the surface tension value of a 3 mmol / kg aqueous solution of component (A) measured by the Wilhelmy method in a 25°C environment, and can be measured specifically by the following method. Furthermore, when component (A) consists of two or more components, the surface tension value of component (A) is calculated as a weighted average based on the surface tension values ​​of the 3 mmol / kg aqueous solutions of each component, with the blending ratio of each component used as the weight. [Method for measuring the surface tension of a 3 mmol / kg aqueous solution of component (A) at 25°C] A 3 mmol / kg aqueous solution of component (A) is prepared in a 25°C environment, poured into a glass Petri dish with a diameter of 6.4 cm and a depth of 3.8 cm, and measurement is performed after removing air bubbles from the water surface and leaving it to stand for 10 minutes or more. In this measurement, a surface tensiometer "K100" (manufactured by KRUSS) is used, and the surface tension value is measured 1 minute after immersing a platinum plate 1 mm into the aqueous solution.

[0069] The present invention will be described below with reference to examples, but is not limited to the scope of the examples. In the examples, various evaluations and measurements were carried out by the following methods.

[0070] (pH) The pH of the spray composition was measured at 25°C using a pH meter (electrode: 6367-10D (manufactured by Horiba, Ltd.)).

[0071] (Viscosity) The viscosity of the spray composition was measured at 25°C at 100 rpm using a viscometer TVB-10M (manufactured by Toki Sangyo Co., Ltd.) with a low viscosity adapter or a rotor appropriate for the measurement range from rotors No. 1 to 4.

[0072] (Proportion of spray droplets with a particle size of less than 20 μm) The volume particle size distribution of the spray droplets was measured by laser diffraction at room temperature (25°C) using a Spraytec laser diffraction system (Malvern Panalytical, model number: STP5921 equipped with a 300 mm lens from the same company). The spray was filled with each composition in a trigger spray container (trigger type: pressure-accumulating, capacity 370 mL, nozzle diameter 0.8 mm, discharge rate: 0.9 g / time) (a trigger sprayer for Lysol Disinfectant EX (manufactured by Kao Corporation)) so that the tip of the spray nozzle of the spray container was located 15 cm horizontally from the measurement area of ​​the laser diffraction system. The composition was sprayed by operating the trigger once, and the volume particle size distribution of the spray droplets detected in the measurement area with a laser length of 34 cm and a laser width of 1.8 cm was measured. The measurement range of the volume particle size distribution using this measuring instrument is 1 to 1000 μm. In the trigger operation, the trigger was pulled at a full stroke with a substantially constant pressure so that the spray direction from the nozzle of the spray container was horizontal to the ground, and the trigger operation time (the time from when the trigger was first pulled to when it was finished) was 0.38 seconds, the liquid discharge time (the time from when the liquid started to be discharged to when it was finished) was 0.22 seconds, and the spray rate (discharge amount / liquid discharge time) was 4.0 g / second. From the measurement results of the volumetric particle size distribution obtained, the proportion of spray droplets with a particle size of less than 20 μm was calculated, and the results are shown in Table 1.

[0073] (Discomfort upon spraying) 100 mL of the spray composition prepared in each example was filled into the trigger spray container (trigger type: pressure-accumulating, capacity 370 mL, nozzle diameter: 0.8 mm, discharge rate: 0.9 g / time) to prepare a spray. The spray composition was sprayed into a sink measuring 55 cm x 140 cm x 25 cm in volume by operating the trigger of the spray five times with a full stroke. Immediately after spraying, the panelists rated the discomfort they felt when they put their faces into the sink and breathed, using the following criteria, and the results are shown in Table 1. The lower the score, the less discomfort there was and the better the result. <Evaluation criteria> 1: No discomfort, no discomfort or irritation felt in the nose and throat 2: Slight discomfort felt in the throat, no irritation felt in the nose and throat 3: Slight discomfort felt in the nose and throat, slight irritation felt 4: Discomfort felt in the nose and throat, irritation felt 5: Great discomfort felt in the nose and throat, considerable irritation felt

[0074] (Spray Uniformity) The spray was placed at a position where the nozzle was 30 cm from the wall and 25 cm from the floor. A 24 cm x 33.5 cm piece of water-sensitive paper was attached to the wall, and the spray was sprayed by operating the trigger of the sprayer once with a full stroke, aiming the spray at the water-sensitive paper. The spray uniformity was evaluated based on the spray marks recorded on the water-sensitive paper using the following criteria, and the results are shown in Table 1. <Evaluation Criteria> A: The spray marks are circular and evenly sprayed. C: Other than the above (the spray marks are non-circular (including doughnut-shaped), the spray is not evenly sprayed, etc.)

[0075] (Spray Area Width) The area of ​​the spray marks obtained in the above "Spray Uniformity" evaluation was subjected to image processing using image analysis software (ImageJ, manufactured by the National Institutes of Health, USA), and the area was calculated using the image conversion function. From the results, the spray area width was evaluated according to the following criteria, and the results are shown in Table 1. <Evaluation Criteria> AA: 400 cm 2 More than A: 200cm 2 More than 400cm 2 Less than B: 100cm 2 More than 200cm 2 Less than C: 100cm 2 less than

[0076] (Mosquito Drop Performance) Three acrylic boxes (6 x 6 x 4 cm) each containing four female Aedes albopictus mosquitoes were prepared and covered on both sides with mesh cloth (nylon, 15D, mesh shape: hexagonal, mesh size: 1.5 mm), and stacked as shown in Figure 1. The spray composition of each example, filled in the trigger spray container, was sprayed onto the stacked acrylic boxes by operating the trigger once with a full stroke from a distance of 40 cm. Of the total of 12 Aedes albopictus mosquitoes, the number of Aedes albopictus mosquitoes that had fallen was counted, and the value of the number of Aedes albopictus mosquitoes that had fallen / 12 x 100 (%) is shown in Table 1. The higher the value, the higher the mosquito drop performance.

[0077] Examples 1 to 9 and Comparative Examples 1 to 4 (Preparation and Evaluation of Spray Compositions) The components shown in Table 1 were blended and mixed with a stirrer to prepare arthropod control spray compositions. The amounts listed in the table are the active ingredient amounts (mass%) of each component. Using the resulting compositions, pH and viscosity were measured by the methods described above. The prepared compositions were also filled into the trigger spray container (trigger type: pressure-accumulating, volume 370 mL, nozzle diameter: 0.8 mm, discharge rate: 0.9 g / time) to produce sprays. Using the resulting sprays, the proportion of spray droplets with a particle size of less than 20 μm, discomfort during spraying, spray uniformity, spray area, and mosquito repelling performance were evaluated by the methods described above. The evaluation results are shown in Table 1.
