Abstract
Description
本発明は、ペット臭等の不快な生活臭を消臭する方法に関する。 The present invention relates to a method for deodorizing unpleasant living odors such as pet odors.
ポビドンヨード（povidon iodine）は、商品名をイソジン（登録商標）とした消毒剤として広く知られている。このポビドンヨードはヨウ素（Ｉ）をキャリアであるポリビニルピロリドン（ＰＶＰ）に結合させた水溶性の複合体である。 Povidon iodine is widely known as a disinfectant whose trade name is Isodine (registered trademark). This povidone iodine is a water-soluble complex in which iodine (I) is bound to polyvinylpyrrolidone (PVP) as a carrier.
上記のポビドンヨードに関する先行技術として、特許文献１及び特許文献２が知られている。
特許文献１は、３カ月以上に亘って有効ヨウ素及び遊離ヨウ素の量を維持することができる組成物として、約０．０１〜１．４重量％の有効ヨウ素、約１０〜１２５ｐｐｍの遊離ヨウ素、約０．００５〜０．５重量％のヨウ素酸イオン、溶液中の該有効ヨウ素を維持するのに十分な量の錯化剤、約０．００４〜０．５０重量％のヨウ化物イオンからなるｐＨが約２．０〜４．５の溶液を提案している。
Patent documents 1 and patent documents 2 are known as prior art about the above-mentioned povidone iodine.
Patent Document 1 discloses that about 0.01 to 1.4% by weight of effective iodine, about 10 to 125 ppm of free iodine, About 0.005 to 0.5 weight percent iodate ion, sufficient amount of complexing agent to maintain the effective iodine in solution, about 0.004 to 0.50 weight percent iodide ion A solution with a pH of about 2.0 to 4.5 is proposed.
特許文献２は、７〜３０質量％のヨウ素、およびこのヨウ素に対してモル比が０．５〜２であるヨウ化アルカリを溶解するアルコール類および多価アルコール類の少なくともいずれか一方の水溶液からなる消毒剤を提案している。 Patent Document 2 discloses an aqueous solution of at least one of alcohols and polyhydric alcohols that dissolve 7 to 30% by mass of iodine and an alkali iodide having a molar ratio of 0.5 to 2 with respect to the iodine. Has proposed a disinfectant.
非特許文献１にはポビドンヨードを消毒剤ではなく、ビタミンＣの定量剤として使用することが記載されている。
即ち、アスコルビン酸（ビタミンＣ）＋ヨウ素（Ｉ2）
→デヒドロアスコルビン酸＋ヨウ化水素（２ＨＩ）
の反応式において、ヨウ素（Ｉ2）は紫〜オレンジ色を呈するが、ヨウ化水素（２ＨＩ）は無色であるので、無色になるまでに滴下した量で、ビタミンＣの定量を行うことが記載されている。
Non-Patent Document 1 describes the use of povidone iodine as a vitamin C quantifier rather than a disinfectant.
That is, ascorbic acid (vitamin C) + iodine (I 2 )
→ Dehydroascorbic acid + hydrogen iodide (2HI)
In the above reaction formula, iodine (I 2 ) has a purple to orange color, but hydrogen iodide (2HI) is colorless, so that vitamin C is quantified in an amount dropped until it becomes colorless. Has been.
上記特許文献１及び特許文献２或いは従来から知られるポビドンヨードを消毒剤や消臭剤として噴霧すると衣服等がヨウ素の色（紫〜オレンジ）に着色させてしまう。このため、着色されるのを嫌う衣服、カーテン、室内或いは車の座席などに付着した悪臭を除去する消臭剤としてこれらを用いた事例はない。 When the above-mentioned Patent Document 1 and Patent Document 2 or the conventionally known povidone iodine is sprayed as a disinfectant or deodorant, clothes and the like are colored in iodine color (purple to orange). For this reason, there is no example which uses these as a deodorant which removes the bad odor adhering to the clothes which dislike coloring, a curtain, a room | chamber interior, or a car seat.
一方、ポビドンヨードに非特許文献１に示すようにビタミンＣを添加するか或いはハイポアルコール（チオ硫酸ナトリウム）を添加すると、中和されて無色透明になる。しかしながら、無色透明になった時点で有効ヨウ素（遊離ヨウ素）はヨウ化水素（ＨＩ）となっており、事実は別として消毒効果は消失するとされている。故に無色透明でしかも悪臭の除去に有効な消臭方法が望まれている。 On the other hand, when vitamin C is added to povidone iodine as shown in Non-Patent Document 1 or hypoalcohol (sodium thiosulfate) is added, it is neutralized and becomes colorless and transparent. However, when it becomes colorless and transparent, effective iodine (free iodine) is hydrogen iodide (HI), and apart from the fact, it is said that the disinfection effect is lost. Therefore, there is a demand for a deodorizing method that is colorless and transparent and that is effective in removing malodors.
上記課題を解決するため、本発明に係る消臭方法は、ポビドンヨードにアスコルビン酸（ビタミンＣ）またはチオ硫酸ナトリウムを添加して中和反応を起こさせてポビドンヨード溶液を無色透明とし、この無色透明なポビドンヨード溶液を水で希釈し、希釈した水溶液に振動などの物理的な刺激を与えることで、目に見えない程小さなミスト(水滴気流)として噴霧する。 In order to solve the above problems, the deodorizing method according to the present invention is to add ascorbic acid (vitamin C) or sodium thiosulfate to povidone iodine to cause a neutralization reaction to make the povidone iodine solution colorless and transparent. The povidone-iodine solution is diluted with water and sprayed as an invisible small mist (water stream) by giving the diluted aqueous solution a physical stimulus such as vibration.
前記ミストは、例えば水面に超音波振エネルギーを与えることで発生させることができる。また水によるポビドンヨード溶液の希釈倍率は好ましくは５００倍以上とする。 The mist can be generated, for example, by applying ultrasonic vibration energy to the water surface. The dilution ratio of the povidone iodine solution with water is preferably 500 times or more.
本発明に係る消臭方法によれば、消臭対象となる衣服、家具、室内、車のシート等を着色することなく、効果的に消臭することができる。 According to the deodorizing method of the present invention, it is possible to effectively deodorize without coloring clothes, furniture, indoors, car seats, and the like that are to be deodorized.
ポビドンヨードにアスコルビン酸（ビタミンＣ）またはチオ硫酸ナトリウムを添加すると中和され無色透明になるが、同時に遊離ヨウ素も消失し、酸化作用による消毒効果もなくなると言われている。しかしながら、本発明者の実験によれば中和反応によって無色透明になったポビドンヨード溶液を水で希釈し、この希釈水溶液をミスト気流にして噴霧拡散することにより、いくつかの消臭市販品よりも高い消臭効果を確認できた。
この理由は、中和反応によって生じたヨウ化水素（ＨＩ）を含む希釈水溶液をミストの気流にすることで各々がイオン化し、遊離ヨウ素と同じような性能を発揮するものと考えられる。
When ascorbic acid (vitamin C) or sodium thiosulfate is added to povidone iodine, it is neutralized and becomes colorless and transparent, but at the same time, free iodine is also lost, and it is said that the disinfection effect due to oxidation action is lost. However, according to the experiments of the present inventor, the povidone iodine solution that became colorless and transparent by the neutralization reaction was diluted with water, and the diluted aqueous solution was sprayed and diffused in a mist air stream, so that it was more effective than some deodorized commercial products. A high deodorizing effect was confirmed.
The reason for this is thought to be that each dilute aqueous solution containing hydrogen iodide (HI) generated by the neutralization reaction is ionized to exhibit the same performance as free iodine.
図１に示すように、ポビドンヨードにアスコルビン酸（ビタミンＣ）またはチオ硫酸ナトリウムを添加する。ポビドンヨードは強酸化剤、アスコルビン酸（ビタミンＣ）またはチオ硫酸ナトリウムは強還元剤であるので、これらを混合すると、中和反応が起こり、ポビドンヨード中のヨウ素（遊離ヨウ素）は無色透明のヨウ化水素（ＨＩ)に変化する。 As shown in FIG. 1, ascorbic acid (vitamin C) or sodium thiosulfate is added to povidone iodine. Povidone iodine is a strong oxidant, and ascorbic acid (vitamin C) or sodium thiosulfate is a strong reducing agent. When these are mixed, neutralization occurs, and iodine (free iodine) in povidone iodine is colorless and transparent hydrogen iodide. It changes to (HI).
市販のポビドンヨード(ポピドンヨード１ｍＬ中７ｍｇの有効ヨウ素)にアスコルビン酸（ビタミンＣ）またはチオ硫酸ナトリウムの添加量は中和（無色透明）になるのに必要な量（当量）とし、当量以上（過剰）は添加しない。 The amount of ascorbic acid (vitamin C) or sodium thiosulfate added to commercially available povidone iodine (7 mg of effective iodine in 1 mL of popidone iodine) should be the amount (equivalent) necessary for neutralization (colorless and transparent), and more than equivalent (excess) Is not added.
次に無色透明となった ポビドンヨードとアスコルビン酸（ビタミンＣ）またはチオ硫酸ナトリウムとの混合液を水で５００〜１０００倍程度に希釈する。このようにして希釈した水溶液を図２に示す容器内に充填する。 Next, a colorless and transparent mixture of povidone iodine and ascorbic acid (vitamin C) or sodium thiosulfate is diluted to about 500 to 1000 times with water. The aqueous solution diluted in this way is filled in the container shown in FIG.
容器はミスト霧化室１と給水室２に分けられ、霧化室１内にはガイド筒３が設けられ、給水室２には給水タンク４が着脱自在に収納され、また霧化室１の外側面にはエア導入通路５が設けられ、このエア導入通路５の底部にはファンモータ６が設けられている。 The container is divided into a mist atomization chamber 1 and a water supply chamber 2, a guide cylinder 3 is provided in the atomization chamber 1, and a water supply tank 4 is detachably stored in the water supply chamber 2. An air introduction passage 5 is provided on the outer side surface, and a fan motor 6 is provided at the bottom of the air introduction passage 5.
また、ミスト霧化室１の底部には圧電振動子７が配置され、この圧電振動子７を駆動する駆動回路８は容器の外側に配置されている。 A piezoelectric vibrator 7 is disposed at the bottom of the mist atomizing chamber 1, and a drive circuit 8 for driving the piezoelectric vibrator 7 is disposed outside the container.
上記容器内に上記の希釈した水溶液を充填し、圧電振動子７を振動させると水溶液表面に超音波の振動エネルギーが伝達され、水面から霧が発生し、この霧はエア導入通路５から霧化室１内に入り、更にガイド筒３の下端の隙間からガイド筒３内を通って室内に散布され、散布されたミスト中にはヨウ化水素（ＨＩ)が含まれているが、このように微細な水滴とすることによって、ヨウ化水素（ＨＩ)のイオン化が一層促進され繊維奥まで浸透容易な状態になり、遊離ヨウ素と同等以上の消臭（菌の不活化）効果を発揮する。 When the diluted aqueous solution is filled in the container and the piezoelectric vibrator 7 is vibrated, ultrasonic vibration energy is transmitted to the surface of the aqueous solution, and mist is generated from the water surface. The mist is atomized from the air introduction passage 5. It enters into the chamber 1 and is further sprayed into the chamber through the guide tube 3 from the gap at the lower end of the guide tube 3, and the sprayed mist contains hydrogen iodide (HI). By forming fine water droplets, ionization of hydrogen iodide (HI) is further promoted and the fiber can be easily penetrated to the back of the fiber, and exhibits a deodorizing effect (inactivation of bacteria) equal to or higher than that of free iodine.

Comparative Example Deodorization target is the interior space of 50 used cars with an odor level of 200 to 300 (230 on average), two deodorant beads (Kobayashi Pharmaceutical: unscented space) are placed in the passenger seat, and the interior is sealed. The engine was run for 10 minutes in the air conditioner circulation state, and after 10 minutes, the door was opened and the same ventilation was performed.
The odor at the foot of the passenger seat before and after the engine was stopped was measured with a portable odor sensor (manufactured by New Cosmos Electric Co., Ltd .: odor sensor mini XP-329m).
本発明方法による場合には、全て中古車内の臭気レベルはいずれも０になっていた。また、当該中古車を所有する顧客に消臭処理から９０日後の臭いの状況を問い合わせたところ、快適である、確実に不快臭が減じているとの連絡を得た。
一方、消臭ビーズを用いて消臭した場合には、平均２０５の臭気レベルが残っていた。また中古車所有者への問い合わせについても効果がないとの回答であった。
In the case of the method according to the present invention, all of the odor levels in the used cars were zero. In addition, when the customer who owned the used car was inquired about the state of odor 90 days after the deodorizing treatment, they were informed that it was comfortable and that the unpleasant odor was surely reduced.
On the other hand, when deodorizing using deodorizing beads, an average of 205 odor levels remained. In addition, it was answered that inquiries to used car owners were not effective.
図示例にあっては、定期的に散布することで室内空間に臭いが発生するのを未然に防止する消臭装置を示したが、衣服、シート、カバー等の特定の対象物に車塗装用のスプレーガンや手動式の噴霧器を用いて散布するようにしてもよい。 In the illustrated example, a deodorizing device that prevents odors from occurring in the indoor space by spraying regularly has been shown, but it is suitable for car painting on specific objects such as clothes, seats, covers, etc. You may make it spray using a spray gun or a manual sprayer.
