Description
본 발명은 폭넓은 적용 범위를 갖는 분무식 살충제 조성물에 관한 것이다.The present invention relates to spray insecticidal compositions having a wide range of applications.
더욱 상세히, 본 발명은 가정위생 해충 구제, 가정용 원예 및 식물 해충 구제, 애완동물 기생해충 구제 등의 여러가지 목적에 적합한 살충제로서, 살충 효과가 우수한 피레스로이드계 살충제인 퍼메스린(Permethrin)을 미세 유화시킨 수성제제임을 특징으로 하는 분무식 살충제 조성물에 관한 것이다.More specifically, the present invention is a pesticide suitable for various purposes, such as home hygiene pest control, home horticulture and plant pest control, pet parasitic pest control, fine emulsification permethrin (Permethrin), a pyrethroid insecticide excellent in insecticide effect It relates to a spray insecticide composition characterized in that the aqueous formulation.
기존의 살충제 제품중에서 가정용으로 사용되는 분무식 살충제는 유성용제에 살충원제를 용해시킨 유성제제가 대부분이고, 가정용 원예 및 식물 해충 구제용으로 사용되는 분무식 살충제는 그러한 특정 용도로 개발된 것이 없고 통상 농약을 희석시켜 사용하는 것이 대부분이다. 또한, 애완동물 기생해충 구제 살충제는 대부분 애완동물용 샴푸 등에 살충원제를 첨가하여 사용하는 제품이 주류를 이루고 있다.Most conventional pesticides used in household pesticide products are oil-based preparations in which insecticides are dissolved in oil-based solvents. Spray insecticides used for household horticulture and plant pest control have not been developed for such specific uses. Most of them are diluted with pesticides. In addition, most of the parasitic pest control pesticides are products that use pesticide additives, such as pet shampoo.
이와 같이 각각의 용도별로 사용되는 살충제들은 타용도로 사용되기 어렵다. 예를들어 가정용으로 사용되는 유성 제형의 분무식 살충제는 식물 해충 구제용으로 사용될 수 없는데, 그 이유는 식물 해충 구제용으로 사용될 경우 가정용 유성 분무식 살충제에 함유되어 있는 기름 성분이 식물의 기공을 막아 식물을 말라 죽게 하기 때문이다. 또한 가정용 분무식 살충제는 애완동물 구제용으로도 역시 기름 성분이 많을 때는 적용이 곤란하다. 한편, 가정용 유성제형 분무식 살충제를 본래의 목적인 가정용으로 사용할 경우에도 역시 유성 용제를 사용할 때는 얼룩 및 오염을 유발시킬 수 있으므로 불편한 점이 있다.As such, the pesticides used for each use are difficult to use for other purposes. For example, spray pesticides in oil-based formulations for home use cannot be used for plant pest control because, when used for plant pest control, the oils contained in household oil spray pesticides block the pores of the plant. This is because the plants dry out and die. In addition, household spray insecticides are difficult to apply when pets are also rich in oil. On the other hand, even when the domestic type oil-based spray insecticide is used as a home for the original purpose, there is also an inconvenience because it can cause stains and contamination when using the oil-based solvent.
따라서 가정용, 식물해충 구제용 및 애완동물 기생해충 구제용 등의 다목적 용으로 사용하기 위한 분무식 살충제는 연속상이 물인 수성제제가 되어야 하고, 식물기공의 폐쇄 방지를 위해 미세 유화 상태로 존재하여야 하며, 분무식 가정용 살충제의 주요 방제 해충인 모기, 파리, 바퀴벌레, 식물해충인 진딧물, 애완동물 기생충인 이, 벼룩 등에 효과가 우수한 살충 원제를 함유하고 있어야 하고, 인간 및 애완동물 등의 가축에 대한 이 살충 원제의 독성은 매우 낮아야 하는 등 여러가지 조건을 만족시켜야 한다.Therefore, spray insecticides for multi-purpose use, such as home, plant pest control and pet parasitic pest control, should be an aqueous formulation with a continuous phase of water, and must exist in a fine emulsified state to prevent the closure of plant pores. It should contain excellent insecticides such as mosquitoes, flies, cockroaches, plant aphids, pet parasites, teeth and fleas, which are the main control pests of spray household pesticides, and these insecticides on livestock such as humans and pets. Toxicity of the original agent must be very low and various conditions must be satisfied.
이에, 본 발명자들은 선행 기술의 여러가지 문제점을 해결함으로써 상기한 바와 같은 장점을 지닌 살충제 조성물을 제조하고자 오랫동안 노력해 온 결과, 본 발명을 완성하게 되었다.Thus, the present inventors have long been trying to produce a pesticide composition having the advantages described above by solving various problems of the prior art, the present invention has been completed.
본 발명의 구성에 대해 좀더 자세히 설명하면 다음과 같다.Hereinafter, the configuration of the present invention will be described in more detail.
본 발명은 상기에 언급한 조건을 만족시키는 분무식 살충제로서, 사람 및 가축에 대한 독성이 낮고 모기, 파리, 바퀴벌레, 개미, 진딧물, 이, 벼룩 등에 살충 효력이 우수하다고 알려져 있는 피레스로이드계 살충제인 퍼메스린을 살충 성분으로 사용하여 이를 유기용매인 정제 등유에 용해시키고 여기에 유화제를 첨가 한 후, 추가로 필요에 따라 결빙 방지제 및 방부제를 첨가하여 물과 미세 유화시킨 살충제 조성물을 제공하는 것을 목적으로 한다.The present invention is a spray insecticide that satisfies the above-mentioned conditions, and is a pyrethroid insecticide known to have low toxicity to humans and livestock and has excellent insecticidal effects on mosquitoes, flies, cockroaches, ants, aphids, teeth, fleas, and the like. The purpose of the present invention is to provide a pesticide composition finely emulsified with water by using permethrin as a pesticide component, dissolving it in refined kerosene, an organic solvent, adding an emulsifier thereto, and further adding an antifreezing agent and a preservative as necessary. It is done.
본 발명에 따른 살충제 조성물에서 유효한 살충 성분으로 사용하는 퍼메스린은 0.10 내지 0.35중량(w/v)% 사용하는 것이 바람직하다. 퍼메스린을 0.10중량(w/v)% 이하로 사용할 경우에는 유화성이 우수하여 미세 유화가 이루어지나 바퀴벌레와 같이 저항성이 강한 위생 해충에 대해서는 효과적인 살충력을 발휘할 수 없고, 0.35중량(w/v)% 이상으로 사용할 때는 미세 유화가 이루어지지 않아 식물에 대한 약해를 유발 시키기 때문이다. 이러한 살충성분의 함량은 보건 사회부의 살충성분 함량고시에 따른 유효 약량을 적용하였다.Permethrin used as an effective pesticide component in the pesticide composition according to the present invention is preferably used 0.10 to 0.35% by weight (w / v)%. When permethrin is used at less than 0.10 weight (w / v)%, fine emulsification is achieved due to its excellent emulsification, but it does not exhibit effective insecticidal effects against hygienic pests such as cockroaches, and 0.35 weight (w / v). This is because when used at more than)%, fine emulsification does not occur, causing harm to plants. The content of these pesticides was applied effective amount according to the notice of pesticide content of the Ministry of Health and Social Affairs.
또한, 본 발명에 따라 미세 유화시킨 살충제 조성물은, 예를들어 유화 입자 크기가 평균 250㎜ 이하의 미세유화를 시켜야만 식물에 약해를 주지 않게 되는 등 유화 상태가 매우 중요하며, 이렇게 유화 상태에 있어 엄격히 조정된 조성물을 제조하기 위해서는 유화재의 종류 및 함량이 매우 중요하므로, 유화 안정성 및 유화 정도가 바람직하게 되는 범위내에서 그 종류 및 함량을 결정하였다. 또한, 용제의 종류 및 함량도 유화 상태에 영향을 미칠 수 있으므로 살충성분을 잘 용해시키는 동시에 유화상태도 바람직하게 유지하기 위해서 유화 실험에 의해 용제의 종류와 함량을 결정하였다. 한편, 결빙 방지제 및 방부제는 영하의 온도에서 살충제의 결빙을 방지하고 미생물의 번식을 막아 제품의 안정성을 증대시키기 위해 경우에 따라 사용된다.In addition, the insecticide composition finely emulsified according to the present invention, for example, the emulsified state is very important, such that the emulsified particle size must be microemulsified with an average particle size of 250 mm or less, so as not to harm the plant. Since the type and content of the emulsifier are very important for preparing the adjusted composition, the type and content were determined within the range in which the emulsion stability and the degree of emulsification are preferred. In addition, since the type and content of the solvent may also affect the emulsification state, the type and content of the solvent were determined by the emulsification experiment in order to dissolve the pesticides well and maintain the emulsification state. Antifreeze and preservatives, on the other hand, are sometimes used to prevent freezing of insecticides at sub-zero temperatures and to prevent the growth of microorganisms to increase product stability.
상기한 바의 엄격한 조건을 만족시킴으로써 본 발명에서 사용된 유화제의 종류 및 함량은 친유성 유화제인 폴리옥시에틸렌노닐페닐에테르 3.8(Polyoxyethylene Nonylphenyl Ether 3.8) 0.06 내지 0.08중량(w/v)% 및 친수성 유화제인 폴리옥시에틸렌노닐페닐에테르 10(Polyoxyethylene Nonylphenyl Ether 10) 0.045 내지 0.055중량(w/v)%이다. 유화제의 함량에 있어서, 폴리옥시에틸렌노닐페닐에테르 3.8이 0.06 내지 0.08중량(w/v)% 범위를 벗어나게 되면 안정한 유화가 이루어지지 않으며 역시 폴리옥시에틸렌노닐페닐에테르 10도 0.045내지 0.055중량(w/v)% 범위를 벗어날 때, 유화가 잘 이루어지지 않고 상이 분리된다.By satisfying the stringent conditions described above, the type and content of the emulsifier used in the present invention are 0.06 to 0.08 weight (w / v)% of a lipophilic emulsifier and a hydrophilic emulsifier. Phosphorus polyoxyethylene nonylphenyl ether 10 is 0.045 to 0.055% by weight (w / v)%. As for the content of the emulsifier, if the polyoxyethylene nonylphenyl ether 3.8 is out of the range of 0.06 to 0.08 weight (w / v)%, stable emulsification is not achieved, and the polyoxyethylene nonylphenyl ether 10 is also 0.045 to 0.055 weight (w / When out of the v)% range, the emulsification is poor and the phases separate.
결빙 방지제 및 방부제는 디아세톤알콜(Diaceton Alcohol), 이소프로필알콜, 벤질알콜, 및 메틸파라벤 중에서 1종 이상을 선택하여 함유할 수 있으며, 0.001 내지 0.003중량(w/v)% 함유하는 것이 바람직하다. 결빙 방지제 및 방부제를 0.001중량(w/v)% 이하로 함유하게 되면 영하 10℃ 이하에서 장기 보존시 결빙이 생기며 0.003중량(w/v)% 이상으로 함유하게 되면 유화에 나쁜 영향을 미치므로 바람직하지 않다.Anti-icing agent and preservative may contain one or more selected from diaceton alcohol, isopropyl alcohol, benzyl alcohol, and methyl paraben, preferably 0.001 to 0.003 weight (w / v)%. . If it contains less than 0.001 weight (w / v)% of anti-freezing agent and preservative, it is preferable to freeze at long term storage below minus 10 ℃, and if it contains more than 0.003 weight (w / v)%, it has a bad effect on emulsification. Not.
한편, 용제로는 정제 등유를 0.51 내지 0.55중량(w/v)% 사용할 수 있는데, 본 발명에서는 엑슨(Exxon, 미국)사 제품인 엑솔 D 80(EXXSOL D 80)을 바람직하게 사용하였다. 유기용제를 0.51중량(w/v)% 이하로 사용하게 되면 살충 성분을 완전히 용해시키기 어려우며 상분리가 일어나고, 0.55중량(w/v)% 이상일 때는 역시 용제량이 너무 많아 미세 유화가 완전히 이루어지지 않는다.On the other hand, as a solvent, 0.51 to 0.55 weight (w / v)% of refined kerosene may be used. In the present invention, Exxon D 80 (EXXSOL D 80) manufactured by Exxon (USA) is preferably used. When the organic solvent is used at 0.51% by weight (w / v) or less, it is difficult to completely dissolve the pesticidal components, and phase separation occurs. When the amount is 0.55% by weight (w / v) or more, the amount of solvent is too large so that fine emulsification is not completed.
본 발명에 따른 분무식 살충제 조성물을 구성하고 있는 살충 성분의 종류 및 함량, 유화재의 종류 및 함량, 용제의 종류 및 함량 등은 유화 상태에 있어 모두 밀접하게 상호 관련되어 있기 때문에 본 발명의 목적을 달성하는데 있어 중요한 구성요건이 된다.The type and content of the pesticidal component, the type and content of the emulsifier, the type and content of the solvent, etc., which constitute the spraying pesticide composition according to the present invention are all closely related to each other in the emulsified state. It is an important component in achieving this.

살충원액 100ml 중In insecticide 100ml
퍼메스린 0.25그람을 엑솔 D 80에 용해시켜 100ml로 조정한 후 분무기에 충진시켜 제조한다.0.25 grams of permethrin is dissolved in Axol D 80, adjusted to 100 ml, and filled into a nebulizer.
실험예 :Experimental Example:
20ℓ 투명 플라스틱 용기의 밑바닥에 각각 실시예와 비교예에서 제조된 살충제를 동일량 분사시킨 후 수컷 성충 바퀴벌레를 20마리 넣어 두어 1일 후 치사율을 관찰함으로써 살충 효력 실험을 수행하였다. 실험은 5회 반복함으로써 그 평균치를 구하였고 그 결과는 하기 표 1에 나타내었다.Insecticide effect experiment was performed by spraying the same amount of pesticides prepared in Examples and Comparative Examples at the bottom of a 20L transparent plastic container, and then putting 20 adult cockroaches and observing lethality after 1 day. The experiment was repeated five times to obtain the average value and the results are shown in Table 1 below.
표 1. 실시예 및 비교예에 의한 조성물의 살충 효력Table 1. Insecticidal effects of the compositions according to Examples and Comparative Examples
통상 살충 성분에 대한 효과는 동일량 적용시 동일 효과를 나타내는 것이 상식이나 제재의 유형을 달리하여 적용시킬 경우 구제 해충의 기피 정도에 따라 효력의 차이가 날 수 있다. 예를들어, 바퀴를 구제 대상으로 하는 분무식 살충제의 경우에는 표면에 살충제를 분사시켜 두고 바퀴가 분사면 위를 지나갈 때 배면에 살충 성분이 묻어 치사에 이르게 되는데, 바퀴에게는 기름 성분이 뿌려진 부분을 피하려는 성향이 있기 때문에 수성제제와 유성제제의 효력 차이가 발생하게 되며 이러한 차이는 상기 표 1에서 통상의 유성제제인 비교예의 경우 평균 치사율이 80%로서 본 발명에 따른 미세 유화 제재에 비해 20%나 효과가 떨어지는 것으로 부터도 명백해진다.In general, the effect on the pesticidal components may have a different effect depending on the degree of avoidance of the exterminating pest when the same effect is applied when the same amount is applied. For example, in the case of spray insecticides for wheels, insecticides are sprayed on the surface, and when the wheels pass over the spray surface, insecticides are put on the back, which leads to fatalities. Due to the tendency to avoid, a difference in the efficacy of the aqueous preparation and the oil preparation occurs, and this difference is 20% compared to the fine emulsifying agent according to the present invention with an average mortality of 80% in the comparative example of the conventional oil preparation in Table 1 above. It becomes clear from me that the effect falls.
또한, 식물 안전성 실험은 관상 식물(드라세나)에 실시예 및 비교예에서 제조된 살충제를 동일량 분사시킨 후 1주일간 방치하여 식물의 고사 정도를 관찰함으로써 수행되었다. 이 실험 역시 5회 반복함으로써 그 평균치를 구하였고 실험 결과는 하기 표 2에 나타내었다.In addition, the plant safety experiment was carried out by spraying the same amount of pesticides prepared in Examples and Comparative Examples to the tubular plants (drasena) and left for one week to observe the degree of death of the plant. This experiment was also repeated five times to obtain the average value and the experimental results are shown in Table 2 below.
표 2. 실시예 및 비교예에 의한 조성물의 식물 안정성 실험Table 2. Plant Stability Experiments of Compositions According to Examples and Comparative Examples
상기 표 1 및 2의 결과로부터 명백히 알 수 있듯이 본 발명에 따라 제조된 살충제 조성물은 유성 살충제에 비해 효력도 우수하며 식물에 거의 무해하다.As can be clearly seen from the results of Tables 1 and 2, the pesticide composition prepared according to the present invention is also excellent in efficacy compared to oily insecticides and is almost harmless to plants.
