Description

[Technical Field]

[0001] The present invention relates to a spray-type insect repellent product. More specifically, the present invention relates to a spray-type insect repellent product in which an insect repellent composition containing essential oils and organic solvents is filled and a nozzle is formed, and which exhibits excellent application discriminability, uniformity of application, and adhesion when the insect repellent composition is sprayed. [Background technology]

[0002] Insect repellents containing N,N-diethyl-m-toluamide (DEET), picaridin, ethyl 3-(Nn-butyl-N-acetyl)aminopropionate, p-menthane-3,8-diol, etc. have been known for some time. (Patent Documents 1, 2, etc.)

[0003] Among these, DEET has restrictions on the number of times it can be used when used by children under 12 years of age. Therefore, some parents want to avoid using DEET or reduce the amount used, and there is research being done on insect repellents that use safer essential oils as the active ingredient instead of DEET (Patent Document 3). [Prior art documents] [Patent Documents]

[0004] [Patent Document 1] Japanese Patent Publication No. 2018-118922 [Patent Document 2] Japanese Patent Publication No. 2018-35150 [Patent Document 3] Japanese Patent Publication No. 2002-173407 [Overview of the Initiative] [Problems that the invention aims to solve]

[0005] However, even with insect repellents that use these highly safe essential oils as active ingredients, spray-type insect repellent products are generally used by parents or guardians to spray and apply them to children (especially preschoolers) to prevent accidental ingestion or inhalation due to misuse. Therefore, when parents or guardians use spray-type insect repellent products on children, it is important to be able to properly identify the applied area, spray the repellent evenly, and ensure that a sufficient amount of the repellent is stably applied during spraying, in order to avoid excessive use of the insect repellent ingredient, uneven application, or missed spots.

[0006] The present invention has been made in view of the above problems, and aims to provide a spray-type insect repellent product in which an insect repellent composition containing essential oils and organic solvents is filled and a nozzle is formed, and which exhibits excellent application discriminability, application uniformity, and application adhesion when the insect repellent composition is sprayed.

[0007] The present inventors conducted diligent studies to solve the above problems and, as a result, found that by filling a spray-type insect repellent product with a nozzle with an insect repellent composition containing essential oils and organic solvents, such that the weight ratio of essential oils to organic solvents is within a certain range, the applicability of the sprayed insect repellent composition is improved, and furthermore, the uniformity and adhesion of the application are also excellent, leading to the completion of the present invention.

[0020] <ph> Furthermore, from the viewpoint of component stability and low irritation to skin and mucous membranes, the insect repellent composition of this embodiment only needs to have a pH (20°C) of 4.3 to 9.0. Preferably, the pH is 4.5 to 9.0, more preferably 5.0 to 9.0, and even more preferably 5.5 to 8.0, making it a weakly acidic or neutral insect repellent composition. The pH of the insect repellent composition can be adjusted as appropriate using a pH adjusting agent such as sodium bicarbonate or sodium hydroxide. The pH of the insect repellent composition can be easily measured using a commercially available pH meter. If the insect repellent composition does not contain water, the pH is defined as the value measured after diluting the insect repellent composition 20 times with purified water.

[0021] <Pump container> The spray-type insect repellent product of this embodiment is an insect repellent product in which the above-mentioned insect repellent composition is filled into a pump container. The material of the pump container is not particularly limited, but examples include polyethylene terephthalate (PET) containers, polyethylene (PE) containers, polypropylene (PP) containers, glass containers, etc. From the viewpoint of handling, polyethylene terephthalate (PET) containers, polyethylene (PE) containers, and polypropylene (PP) containers are preferred, and polyethylene terephthalate (PET) containers are more preferred. The container may be transparent or opaque, colorless or colored, and may contain glitter. If the container is colored, the color of the container is not particularly limited, but examples include green, blue, pink, red, yellow, etc. Also, when using a transparent container, part or all of the container may be covered with a film or the like. For example, the transparent area is not particularly limited as long as there is a transparent area in which the contents can be seen, such as a container in which the label / printed part for content indication is opaque or semi-transparent and the rest is transparent, or an opaque container that has only a transparent part the size of a viewing window.

[0022] <Actuator> The actuator is a component that closes the opening of the pump container and sprays the insect repellent composition filled inside the pump container. The actuator has a valve mechanism for dispensing the insect repellent composition filled inside the pump container, a stem mechanism for operating the valve mechanism, and a nozzle that works in conjunction with the stem mechanism to spray the insect repellent composition dispensed by the valve mechanism. The spraying component also has a trigger that is operated by the user.

[0023] In this embodiment, the spray-type insect repellent product is activated by the user operating the trigger, which activates the stem mechanism and valve mechanism, allowing the insect repellent composition to be dispensed from the pump container and sprayed from the nozzle of the spraying member.

[0024] The shape of the actuator is not particularly limited, but examples include trigger type and finger pump type. The size of the nozzle of these actuators is, for example, 0.05 to 1.0 mm in diameter, and there may be one or more nozzles. The inner diameter of the dip tube is, for example, 1.0 to 10.0 mm, with 1.0 to 5.0 mm being preferred. The amount injected per injection is, for example, 0.05 to 3.0 mL, with 0.05 to 1.5 mL being preferred. In the case of a pressurized pump, the amount injected per second is, for example, 0.1 g to 5.0 g.

[0025] The method for manufacturing the spray-type insect repellent product of this embodiment is not particularly limited. For example, the spray-type insect repellent product can be manufactured by filling a pump container with an insect repellent composition and closing the opening of the transparent container with an actuator.

[0026] The pest repellent composition sprayed by the spray-type insect repellent product of this embodiment has a median particle size (D) at a distance of 15 cm from the nozzle. 50 The lower limit of r15 is preferably 30 μm or more, more preferably 50 μm or more, and even more preferably 60 μm or more, from the viewpoint of obtaining the desired effects of this embodiment in a significant manner. Also, the median particle size (D 50 The upper limit of r15 is preferably 160 μm or less, more preferably 150 μm or less, and even more preferably 100 μm or less, from the viewpoint of obtaining the desired effect of this embodiment in a significant manner. Note that the median particle size (D) of the insect repellent composition at a position 15 cm away from the nozzle of the spray-type insect repellent product. 50 r15 can be measured using the Spraytec laser light scattering particle size distribution analyzer (manufactured by Malvern Panalytical).

[0027] The target area for spraying the insect repellent spray of this embodiment is not particularly limited, but examples include the human body and clothing. Considering the spirit of the present invention, which is excellent in application discriminability, application uniformity, and application adhesion, it can be suitably sprayed on the human body, and more suitably sprayed on the arms or ankles. Furthermore, the target age for use of the insect repellent spray of this embodiment is not particularly limited, but it can be used by both adults and children. In particular, it can be suitably used by children aged 0 to 12 years, and more suitably used by children aged 0 to 6 years.

[0028] [Second Embodiment] In this embodiment, one example of a spray-type insect repellent product is described in which the spray-type insect repellent product is an aerosol product. The spray-type insect repellent product of this embodiment is an aerosol product comprising an aerosol container pressurized and filled with an insect repellent composition and a propellant, and an actuator attached to the aerosol container and having a nozzle formed thereon.

[0029] <Insect repellent composition> The insect repellent composition is the contents that are pressurized and filled into an aerosol container together with a propellant, as described later, and contains (a) essential oil and (b) an organic solvent, and the weight ratio of component (a) to component (b), (b) / (a), is adjusted so that 1 ≤ (b) / (a) ≤ 350. In the first embodiment, it is the same as the insect repellent composition described above.

[0030] <propellant> The propellant is the contents that are pressurized and filled into the aerosol container together with the insect repellent composition. The propellant is sprayed together with the insect repellent composition when an actuator, described later, is activated. At that time, the propellant provides the propulsion force for spraying the insect repellent composition and also atomizes the insect repellent composition.

[0031] The propellants are not particularly limited, but examples include liquefied petroleum gas (LPG) such as propane, n-butane, and isobutane; liquefied gases such as n-pentane, isopentane, dimethyl ether (DME), and hydrofluoroolefins such as trans-1,3,3,3-tetrafluoropropane-1-ene, trans-2,3,3,3-tetrafluoropropane-1-ene, and HFO1234ze; and compressed gases such as nitrogen gas, carbon dioxide, nitrous oxide, and compressed air. The above propellants can be used alone or in mixtures, and liquefied gases and compressed gases may be used in combination.

[0032] When liquefied gas is used as a propellant, the amount of liquefied gas to be filled is not particularly limited. For example, the amount of liquefied gas filled is 20 to 80% by volume relative to the total amount of the insect repellent composition and the propellant. Furthermore, it is preferable that the amount of liquefied gas filled is such that the pressure inside the aerosol container at 25°C is 0.1 to 0.7 MPa.

[0033] When compressed gas is used as a propellant, the amount of compressed gas to be filled is not particularly limited. For example, the amount of compressed gas to be filled is such that the pressure inside the aerosol container at 25°C is 0.1 to 1.0 MPa.

[0034] <Aerosol container> In this embodiment, the insect repellent composition is pressurized and filled into an aerosol container. The aerosol container is not particularly limited, but one example is a substantially cylindrical pressure-resistant container with an opening formed at the top. The opening is a filling port for filling with the insect repellent composition, and after the insect repellent composition is filled, it is closed by an actuator described later.

[0035] The material of an aerosol container is not particularly limited, but examples include metal containers such as aluminum or tinplate, polyethylene terephthalate (PET) containers, and pressure-resistant glass containers.

[0036] <Actuator> The actuator is a component that closes the opening of the aerosol container and sprays the insect repellent composition filled in the aerosol container together with the propellant. The actuator comprises a valve mechanism for dispensing the insect repellent composition and propellant filled in the aerosol container, a stem mechanism for operating the valve mechanism, and a spraying member that works in conjunction with the stem mechanism to spray the insect repellent composition dispensed by the valve mechanism together with the propellant. The spraying member has a nozzle formed therein for spraying the insect repellent composition together with the propellant. The spraying member also includes a trigger that is operated by the user.

[0037] In this embodiment of the spray-type insect repellent product, the trigger is operated by the user, which activates the stem mechanism and valve mechanism, creating communication between the inside and outside of the aerosol container. As a result, the insect repellent composition and propellant inside the aerosol container are drawn out of the aerosol container according to the pressure difference between the inside and outside of the container and sprayed from the nozzle of the spraying member.

[0038] The method for manufacturing the spray-type insect repellent product of this embodiment is not particularly limited. For example, the spray-type insect repellent product can be manufactured by filling an aerosol container with an insect repellent composition, opening and closing the aerosol container with an actuator, and pressurizing and filling the propellant through the nozzle or stem mechanism of the actuator's spraying member.

[0039] The pest repellent composition sprayed by the spray-type insect repellent product of this embodiment has a median particle size (D) at a distance of 15 cm from the nozzle. 50 The lower limit of r15 is preferably 30 μm or more, more preferably 50 μm or more, and even more preferably 60 μm or more, from the viewpoint of obtaining the desired effects of this embodiment in a significant manner. Also, the median particle size (D 50 The upper limit of r15 is preferably 160 μm or less, more preferably 150 μm or less, and even more preferably 100 μm or less, from the viewpoint of obtaining the desired effect of this embodiment in a significant manner. Note that the median particle size (D) of the insect repellent composition at a position 15 cm away from the nozzle of the spray-type insect repellent product. 50 r15 can be measured using the Spraytec laser light scattering particle size distribution analyzer (manufactured by Malvern Panalytical).

[0040] The target area for spraying the insect repellent spray of this embodiment is not particularly limited, but examples include the human body and clothing. Considering the spirit of the present invention, which is excellent in application discriminability, application uniformity, and application adhesion, it can be suitably sprayed on the human body, and more suitably sprayed on the arms or ankles. Furthermore, the target age for use of the insect repellent spray of this embodiment is not particularly limited, but it can be used by both adults and children. In particular, it can be suitably used by children aged 0 to 12 years, and more suitably used by children aged 0 to 6 years. [Examples]

[0041] The present invention will be described in detail below with reference to examples, but the present invention is not limited to these examples.

[0042] [1] Efficacy Test 1 (a) 2.0 g (2.0 w / v%) of peppermint oil, (b) 45 g (45 w / v%) of anhydrous ethanol, and purified water were mixed to prepare a total volume of 100 mL of insect repellent composition. The insect repellent composition was filled into a spray container A equipped with a push-down actuator and a nozzle, and the spray-type insect repellent product of Example 1 was manufactured. The median particle size (D) of the insect repellent composition at a distance of 15 cm from the nozzle of the spray-type insect repellent product was measured. 50 ) The r15 was 60 to 80 μm.

[0043] Furthermore, as described in Tables 1 and 2, each component was blended, and the other procedures were the same as in Example 1 to produce spray-type pest repellent products of Examples 2 to 14 and Comparative Examples 1 to 3. The median particle diameter (D) of the pest repellent composition at a position 15 cm away from the nozzle of each spray-type pest repellent product 50 ) The r15 was measured by a laser light scattering method particle size distribution measuring device Spraytec (manufactured by Malvern Panalytical). In the present invention, by properly using the following spray containers A to E, the particle size distribution range could be generally adjusted. Spray container A: 60 - 80 μm [[ID=!1]]Spray container B: 80 - 95 μm Spray container C: 100 - 145 μm Spray container D: 150 - 160 μm Spray container E: 30 - 50 μm

[0044] [Coating Discrimination Test] Using the spray-type pest repellent product of Example 1, it was randomly applied to several of the four locations on the left and right ankle and forearm of the mannequin. After 30 minutes, three researchers were asked to answer whether the pest repellent composition was applied without touching each of the four locations, and the average value of the correct answer rate of each subject was obtained and evaluated in three levels according to the following criteria. The same test was also conducted on the spray-type pest repellent products of Examples 2 to 14 and Comparative Examples 1 to 3. (The test results are described in Tables 1 and 2.) [[ID=!4]] [Evaluation Criteria] A; 90% < (correct answer rate) ≤ 100% B; 80% < (correct answer rate) ≤ 90% C; (correct answer rate) ≤ 80%

[0045] [Coating Uniformity Test] It should be noted that there was a small error in the original text where "!1" and "!4" were used instead of "11" and "24" respectively. These have been corrected in the translation for clarity.0.1 g of 7-hydroxycoumarin was added as a fluorescent component to the spray-type insect repellent product of Example 1. The nozzle was set approximately 15 cm away from the arm opposite the dominant arm, and one spray was applied. Afterwards, the room lights were turned off, and the sprayed arm was illuminated with a 20 W black light to observe the spraying pattern. The uniformity of the application was evaluated on a three-point scale according to the following criteria. The evaluation was decided by discussion among all five researchers. Similar tests were conducted on the spray-type insect repellent products of Examples 2-14 and Comparative Examples 1-3. (The test results are shown in Tables 1 and 2.) (Evaluation Criteria) A; evenly applied, B; somewhat uneven, C; Non-uniform

[0046] [Coating adhesion test] A 20cm x 20cm filter paper was placed upright in a tray, and the spray-type insect repellent product of Example 1 was sprayed horizontally from 15cm away from the filter paper. After 30 seconds of spraying, the filter paper was collected, and the weight of the product adhering to the filter paper and the spray weight of the insect repellent product were determined by weight measurement. The adhesion rate was calculated using the following formula (Adhesion rate (%) = Weight adhering to filter paper / Spray weight of sample × 100). The test was repeated 5 times to determine the average adhesion rate and the minimum adhesion rate. The adhesion properties were evaluated on a 3-point scale according to the following criteria. Similar tests were performed on the spray-type insect repellent products of Examples 2-14 and Comparative Examples 1-3. (Test results are shown in Tables 1 and 2.) (Evaluation Criteria) A;[(average adhesion rate)-(minimum adhesion rate)]×100 / (average adhesion rate)≦5%, B;5%<[(average adhesion rate)-(minimum adhesion rate)]×100 / (average adhesion rate)≦10%, C;10%<[(average adhesion rate)-(minimum adhesion rate)]×100 / (average adhesion rate)

[0047] [Table 1]

[0048] [Table 2]

[0049] From the above test results, in Comparative Example 1, where component (a) is not an essential oil, the application discrimination was insufficient. In Comparative Example 2, where (b) / (a) was less than 1, the application uniformity was insufficient, and in Comparative Example 3, where (b) / (a) was greater than 350, both the application uniformity and application adhesion were insufficient.

[0050] On the other hand, in Examples 1 to 14, where the combined weight ratio (b) / (a) of component (a) to component (b) was within the range of 1 ≤ (b) / (a) ≤ 350, it was found that good results were obtained in terms of application discriminability, application uniformity, and application adhesion (one or more A's and the rest B's). In particular, the median particle size (D) of the insect repellent composition at a distance of 15 cm from the nozzle was found to be good. 50 In Examples 1-4, 6-8, 10, and 12, where r15 is 60-100 μm and the combined weight ratio of component (a) to component (b) (b) / (a) is in the range of 2 ≤ (b) / (a) ≤ 100, it was found that even better results (all A) were observed in terms of coating discriminability, coating uniformity, and coating adhesion.< / ph>
