Abstract

<P>PROBLEM TO BE SOLVED: To provide a bactericide usable even in its vaporized condition, serving for preventing the outbreaks of harms by microbes seen in many sectors including medical institutions and the food industry. <P>SOLUTION: Disodium ethylenediaminetetraacetate as chelating agent and ferric chloride are dissolved in an aqueous common salt solution. Equal amounts of the resultant solution and 99.5% ethanol are mixed together followed by adding concentrated hydrochloric acid to the mixture to adjust the resulting pH to 0.3(solution A), or dissolving potassium iodide in the mixture so as to be 50 mM in the potassium iodide concentration(solution B). The solution A or B is absorbed into either one of paper, natural sponge, artificial sponge, cotton and chemical fiber or a combination of two or more of them, and then vaporized. Subsequently, Bacillus subtilis spores are exposed to the resultant vapor, thus enabling the spores to be killed completely. <P>COPYRIGHT: (C)2008,JPO&INPIT

従来、気相化状態で使用する殺菌剤としてエチレンオキサイドガスやホルムアルデヒドガスなどある。しかし、いずれの殺菌剤も人体に対しての発ガン性が指摘されてきており、加えて環境に対しても有害であることなどから、これらの殺菌剤の使用は強く制限される傾向にある。また、本申請者が研究してきた殺菌剤は液体の状態で使用するものであり、気相化状態では使用できなかった。  Conventionally, there are ethylene oxide gas, formaldehyde gas and the like as bactericides used in a vaporized state. However, since any of the bactericides has been pointed out to be carcinogenic to the human body and is also harmful to the environment, the use of these bactericides tends to be strongly restricted. . In addition, the disinfectant studied by the applicant is used in a liquid state and cannot be used in a vaporized state.

本発明は、これらの殺菌剤が有する問題を解決しようとするものであり、生体や環境に対してより安全性が高い殺菌剤を開発し、医療、公衆衛生、食品産業など多方面で発生する微生物による危害の発生予防に役立つのみならず、炭疽菌の芽胞をはじめとする微生物を用いたバイオテロに対する危機管理対策にも役立つ殺菌剤を提供することを目的としている。  The present invention is intended to solve the problems of these disinfectants, and develops disinfectants that are safer to living bodies and the environment, and occurs in various fields such as medical, public health, and food industries. The purpose of the present invention is to provide a bactericidal agent that is useful not only for preventing the occurrence of harm caused by microorganisms but also for risk management measures against bioterrorism using microorganisms such as spores of anthrax.

本発明は上記目的を達成するために、キレート剤、金属化合物、ハロゲン化合物、食塩、アルコールと水を組み合わせ、pHを極端に低くすることを特徴とする殺菌剤(1)、塩化ナトリウム、エタノール及び水を組み合わせ、pHを極端に低くすることを特徴とする殺菌剤(2)、殺菌剤(1)と塩化ナトリウム、エタノール及び緩衝液を混合させた殺菌剤(3)のいずれかを、自然蒸発、加温、加熱、超音波、プラズマ化、圧縮、真空、減圧又は攪拌のいずれか一つ又は複数の組み合わせで金属性の容器又は非金属性の容器内で気相化させることによって細菌芽胞を殺す効果が得られる。  To achieve the above object, the present invention combines a chelating agent, a metal compound, a halogen compound, sodium chloride, alcohol and water to make the pH extremely low, sodium chloride, ethanol and Natural evaporation of any of the bactericides (2), bactericides (1), and bactericides (3) mixed with sodium chloride, ethanol and buffer, characterized by combining water and making the pH extremely low Bacterial spores by vaporizing in a metallic container or non-metallic container in one or a combination of heating, heating, ultrasonic, plasma, compression, vacuum, reduced pressure or stirring The killing effect is obtained.

第2の課題解決手段は、殺菌剤(1、2又は3)を紙、天然海綿体、人工海綿体、綿、化学繊維のいずれか一つ又は複数の組み合わせによって吸収させてから、上記第1の課題解決手段を用いて気相化させることによっても細菌芽胞を殺す効果が得られる。  The second problem-solving means is that the disinfectant (1, 2, or 3) is absorbed by any one or a combination of paper, natural sponge body, artificial sponge body, cotton, and chemical fiber, and then the first. The effect of killing bacterial spores can also be obtained by vaporizing using the problem solving means.

第3の課題解決手段は、温度は10℃〜500℃の範囲で用いることによって強い殺芽胞効果が得られる。  The third problem solving means can obtain a strong sporicidal effect by using the temperature in the range of 10 ° C to 500 ° C.

第4の課題解決手段は、湿度は5%〜95%の範囲で用いることによって強い殺芽胞効果が得られる。  The fourth problem-solving means can obtain a strong sporicidal effect by using the humidity in the range of 5% to 95%.

第5の課題解決手段は、空間は必要であり、本剤と金属製の材質が接触する部分は、合成樹脂の材質で置き換えるか、金属性の材質を合成樹脂の材質の物によって被服することにより、殺菌剤(1、2又は3)による腐食を防ぐことができる。  The fifth problem solving means is that space is required, and the part where the agent and the metal material are in contact with each other is replaced with a synthetic resin material, or a metallic material is covered with a synthetic resin material. Thus, corrosion due to the disinfectant (1, 2 or 3) can be prevented.

上述したように、殺菌剤(1、2又は3)を気相化させることによって、屋内や空間に存在して危害を及ぼす可能性のある芽胞を含む微生物を殺すことができる。  As described above, by vaporizing the bactericidal agent (1, 2 or 3), it is possible to kill microorganisms containing spores that exist in the room or space and may cause harm.

以下、本発明の実施の形態を実験結果に基づいて説明する。  Hereinafter, embodiments of the present invention will be described based on experimental results.

These test carriers were placed on an inner side wall and an inner ceiling of a synthetic resin container (hereinafter referred to as a chamber) having a volume of about 95 liters (length 30 cm × width 53 cm × height 60 cm), respectively. A total of 24 non-absorbent materials (six polypropylene bars with serum and six polypropylene bars without serum) were attached. In order to heat and stir the solution (A) or (B), a stainless steel tray (length 13.5 cm × width 20 cm × depth 2 cm) is placed on the hot stirrer heating plate, and the solution (A or B) is placed on this tray. Pour 50 ml and cover the chamber. Turn on the hot stirrer and start heating and stirring. The solution (A) or (B) evaporates with the passage of time and fills the chamber after about 10 minutes. The humidity at this time is around 80%. About 20 minutes later, in a state where heating and stirring were stopped and left as it was, it was examined how many 24 test carriers could be sterilized after 24 hours by exposure to the gas phase of this drug. . As a result, as shown in Table 1, the solution (A) was able to sterilize all test carriers after 16 hours of exposure. On the other hand, as shown in Table 2, solution (B) was able to sterilize all test carriers after 6 hours of exposure.
