Description

本発明は、ノロウイルス不活性化剤に関するものである。 The present invention relates to a norovirus inactivating agent.

大腸菌O−157による食中毒事件の多発に始まり、その後、新型肺炎SARSが猛威を振い、ここ数年はノロウイルスによる食中毒が多発している。2009年の春には新型インフルエンザが発生してパンデミック寸前の状態になり、除菌衛生に対する関心は高まる一方である。
大腸菌O−157による食中毒事件が多発した1996年以降、多くの家庭用品で抗菌性が付与されており、使用される薬剤としては、銀、銅などの金属化合物を利用したものが多い。例えば、銀ブロム又はヨード錯体の塩を含有する抗菌性繊維(特許文献1:特開2008−338481号公報)が知られているが、その防カビ効果は小さく、ウイルスに対する効果も十分でない。
Beginning with frequent occurrences of food poisoning caused by Escherichia coli O-157, the new type of pneumonia SARS has been rampant, and food poisoning due to norovirus has been frequent in recent years. In the spring of 2009, an outbreak of new influenza was on the verge of a pandemic, and interest in sanitary sanitation is increasing.
Since 1996, when many cases of food poisoning due to E. coli O-157 occurred, many household products have been given antibacterial properties, and many of the drugs used use metal compounds such as silver and copper. For example, although an antibacterial fiber containing a salt of silver bromide or an iodine complex (Patent Document 1: Japanese Patent Application Laid-Open No. 2008-338481) is known, its antifungal effect is small and the effect on viruses is not sufficient.

一方、抗ウイルス剤もしくは抗ウイルス効果を謳った製品も、いくつか提案されている。例えば、少なくとも一箇所にフェノール性水酸基を有する、非水溶性の芳香族ヒドロキシ化合物を有効成分とする抗ウイルス剤を塗布あるいは混合させてなる繊維(特許文献2:特開2005―112748号公報)、濾材の少なくとも1層に水酸基とカルボキシル基を同時に有するヒドロキシ酸が含有されてなる抗ウイルスマスク(特許文献3:特開2005−198676号公報)、ポリ−オキシエチレン(ジメチルイミノ)エチレン(ジメチルイミノ)エチレンジクロライドを含有する繊維用抗ウイルス加工剤(特許文献4:特開2008−115506号公報)、2−ピリジンチオール亜鉛−1−オキシド、2−ピリジンチオール銅−1−オキシド、又はこれらの両方を含む抗ウイルス剤で処理された抗ウイルス性繊維(特許文献5:特開2009−7736号公報)等が知られている。 On the other hand, some antiviral agents or products with an antiviral effect have been proposed. For example, a fiber formed by applying or mixing an antiviral agent having a water-insoluble aromatic hydroxy compound having a phenolic hydroxyl group in at least one place (Patent Document 2: JP-A-2005-112748), Antiviral mask (Patent Document 3: Japanese Patent Laid-Open No. 2005-198676), poly-oxyethylene (dimethylimino) ethylene (dimethylimino), wherein at least one layer of the filter medium contains a hydroxy acid having a hydroxyl group and a carboxyl group at the same time An antiviral processing agent for fibers containing ethylene dichloride (Patent Document 4: JP 2008-115506 A), 2-pyridinethiol zinc-1-oxide, 2-pyridinethiol copper-1-oxide, or both Antiviral fiber treated with an antiviral agent (Patent Document 5) JP 2009-7736 JP), and the like.

ところで、特許文献6(特開2008−214268号公報)は、分子末端に2個のピリジン環またはキノリン環を有し、該ピリジン環またはキノリン環の窒素原子が第4級アンモニウム基となっている抗ウイルス剤を開示する。しかしながら、特許文献6に記載されている抗ウイルス効果は、インフルエンザウイルスに対する効果に留まり、ノロウイルスに効果があるとの記載はない。
ノロウイルスは、エンベロープを持たないウイルスであり、通常の抗ウイルス剤はインフルエンザウイルスに有効でもノロウイルスに効きにくいというのが従来の知見であった。
By the way, Patent Document 6 (Japanese Patent Laid-Open No. 2008-214268) has two pyridine rings or quinoline rings at the molecular ends, and the nitrogen atom of the pyridine ring or quinoline ring is a quaternary ammonium group. Antiviral agents are disclosed. However, the antiviral effect described in Patent Document 6 is limited to the effect against influenza virus, and there is no description that it is effective against norovirus.
Norovirus is a virus that does not have an envelope, and it has been a conventional finding that ordinary antiviral agents are effective against influenza viruses but are less effective against noroviruses.

従って、ノロウイルスを不活性化しようとすると、煮沸や塩素系消毒剤の使用に頼るしかなかったが、反応性の高い酸化剤である塩素系薬剤は、安全性の点で問題が多いし、例えば、繊維処理に用いることは技術的にも難しい。
最近の特許文献7(特開2008−189645号公報)によれば、低級アルコール、アルカリ性物質及びカチオン界面活性剤を含む組成物がノロウイルスに有効である旨開示されているが、この組成物にしても、アルカリ性物質を使用するため、安全性に対する危惧は避けられない。
このように、安全性が高くかつノロウイルスに有効なノロウイルス不活性化剤は未だ知られていない。
本発明者らは、特許文献6の一般式に包含される化合物群のうち、1,4―ビス(3,3’―(1―デシルピリジニウム)メチルオキシ)ブタンジブロマイドに着目し、この化合物がインフルエンザウイルスのみならず、ノロウイルスに対しても特異的に有効であることを知見して本発明を完成するに至ったものである。
Therefore, in order to inactivate norovirus, we had to rely on boiling or the use of chlorinated disinfectants, but chlorinated drugs that are highly reactive oxidizing agents have many problems in terms of safety, for example, It is technically difficult to use for fiber processing.
According to recent patent document 7 (Japanese Patent Laid-Open No. 2008-189645), it is disclosed that a composition containing a lower alcohol, an alkaline substance and a cationic surfactant is effective against norovirus. However, since alkaline substances are used, there is an unavoidable concern about safety.
Thus, norovirus inactivating agents that are highly safe and effective for norovirus have not yet been known.
The present inventors paid attention to 1,4-bis (3,3 ′-(1-decylpyridinium) methyloxy) butanedibromide among the compounds included in the general formula of Patent Document 6, and this compound. Has been found to be specifically effective against not only influenza viruses but also noroviruses, and the present invention has been completed.

本発明は、安全性が高くかつノロウイルスに有効なノロウイルス不活性化剤を提供することを目的とする。 An object of the present invention is to provide a norovirus inactivating agent that is highly safe and effective for norovirus.

本発明は、以下の構成が上記目的を達成するために優れた効果を奏することを見出したものである。
(1)(a)1,4―ビス(3,3’―(1―デシルピリジニウム)メチルオキシ)ブタンジブロマイドを0.01〜5.0質量%と、(b)エタノール及びイソプロパノールの1種以上である低級アルコールを20〜60質量%と、(c)水を配合したノロウイルス不活性化剤。
(2)更に、(d)サトウキビエキス、緑茶抽出エキス、チャ乾留物、柿抽出エキス、グレープフルーツ抽出エキス、モウゾウチク抽出エキス、ユズ種子抽出エキス、レンギョウ抽出エキスから選ばれる1種又は2種以上の植物抽出消臭剤を0.01〜2.0質量%配合した(1)記載のノロウイルス不活性化剤。
The present invention has been found that the following constitution has an excellent effect for achieving the above-mentioned object.
(1) 0.01-5.0% by mass of (a) 1,4-bis (3,3 ′-(1-decylpyridinium) methyloxy) butanedibromide, and (b) one of ethanol and isopropanol The norovirus inactivating agent which mix | blended 20-60 mass% of the lower alcohol which is the above, and (c) water.
(2) Further, (d) one or more plants selected from sugarcane extract, green tea extract, tea dry extract, koji extract, grapefruit extract, mozochiku extract, yuzu seed extract, forsythia extract The norovirus inactivating agent according to (1), wherein 0.01 to 2.0% by mass of an extraction deodorant is blended.

本発明のノロウイルス不活性化剤は、安全性が高くかつノロウイルスに優れた効果を示すので非常に有用である。 The norovirus inactivating agent of the present invention is very useful because it is highly safe and exhibits an excellent effect on norovirus.

本発明で用いる化合物、1,4―ビス(3,3’―(1―デシルピリジニウム)メチルオキシ)ブタンジブロマイド[以降、化合物Aと称す]は、特許文献6の一般式に包含され、抗ウイルス剤として公知であるが、本発明者らは鋭意試験を繰り返し、化合物Aが特許文献6の化合物群のなかでも特異的に、インフルエンザウイルスのみならずノロウイルスに対しても効果を奏することを新たに見出したのである。
化合物Aは、本発明のノロウイルス不活性化剤中に0.01〜5.0質量%配合される。0.01質量%より少ないと確実な効果が得られないし、一方、5.0質量%を超えると製剤の物性に影響を及ぼす恐れがある。コスト、安全性等を考慮し、0.05〜1.0質量%の配合が好ましい。
The compound used in the present invention, 1,4-bis (3,3 ′-(1-decylpyridinium) methyloxy) butanedibromide [hereinafter referred to as Compound A], is included in the general formula of Patent Document 6, Although known as a virus agent, the present inventors have repeated intensive studies, and it has been renewed that Compound A is effective not only for influenza virus but also for norovirus in the compound group of Patent Document 6. I found it.
Compound A is blended in an amount of 0.01 to 5.0% by mass in the norovirus inactivating agent of the present invention. If the amount is less than 0.01% by mass, a certain effect cannot be obtained. On the other hand, if it exceeds 5.0% by mass, the physical properties of the preparation may be affected. In consideration of cost, safety, etc., 0.05 to 1.0% by mass is preferable.

また、ノロウイルス不活性化剤は、低級アルコールを20〜60質量%と水の配合を必須とする。低級アルコールとしては、エタノールやイソプロパノールがあげられるが、細菌、カビ、ウイルスに対する即効性を付与する効果を考慮して、エタノールが好ましい。エタノールの使用は、例えば、繊維製品に噴霧処理した時にノロウイルス不活性化剤が速やかに乾燥しベタツキを生じないというメリットも有する。
なお、水は化合物Aの溶解剤として配合される。
In addition, the norovirus inactivating agent requires the blending of 20-60 mass% of lower alcohol and water. Examples of the lower alcohol include ethanol and isopropanol, and ethanol is preferable in consideration of the effect of imparting immediate effects on bacteria, molds and viruses. The use of ethanol also has an advantage that, for example, when a textile product is sprayed, the norovirus inactivating agent is quickly dried and does not cause stickiness.
Water is added as a solubilizer for compound A.

本発明では、更に、植物抽出消臭剤を0.01〜2.0質量%を配合するのが好ましい。即ち、植物抽出消臭剤は、試験の結果、消臭効果だけでなく、化合物Aのノロウイルス不活性化作用を助長することが見出され、併用することによって、より優れた組成物が提供される。
かかる植物抽出消臭剤としては、サトウキビエキス、緑茶抽出エキス、チャ乾留物、柿抽出エキス、グレープフルーツ抽出エキス、モウゾウチク抽出エキス、ユズ種子抽出エキス、レンギョウ抽出エキス等があげられるが、なかんずくサトウキビエキスが好適である。
In this invention, it is preferable to mix | blend 0.01-2.0 mass% of plant extraction deodorizers further. That is, as a result of the test, the plant-extracted deodorant was found to promote not only the deodorizing effect but also the norovirus inactivating action of Compound A, and by using it together, a more excellent composition is provided. The
Examples of such a plant extract deodorant include sugarcane extract, green tea extract, tea dried product, koji extract, grapefruit extract extract, mozochiku extract extract, yuzu seed extract, forsythia extract, etc. Is preferred.

本発明のノロウイルス不活性化剤には、更に、抗菌効果、防藻効果、あるいは防錆効果、洗浄効果、撥水効果、防汚効果等を付与するために、銀系、銅系等の無機抗菌剤やポリリジン、キトサン等の有機抗菌剤、防藻剤、防錆剤、界面活性剤、撥水剤、防汚剤、溶剤等を適宜配合したり、あるいは、香料等を配合して芳香性を付与するようにしてもよい。 The norovirus inactivating agent of the present invention further includes an antibacterial effect, an algal control effect, or an antirust effect, a cleaning effect, a water repellent effect, an antifouling effect, etc. Organic antibacterial agents such as antibacterial agents, polylysine, chitosan, algae-proofing agents, rust-preventing agents, surfactants, water repellents, antifouling agents, solvents, etc. May be given.

こうして得られた本発明のノロウイルス不活性化剤は、安全性に優れたものであり、台所、流し台、冷蔵庫等の食品を取り扱う場所、居室や寝室、トイレ等の居住空間、ソファー、クッション、寝具、カーテン、マスク等の繊維製品等の処理に効果的で有用性が高い。 The norovirus inactivating agent of the present invention thus obtained is excellent in safety and is used for food handling such as kitchens, sinks, refrigerators, living spaces such as living rooms and bedrooms, toilets, sofas, cushions, bedding It is effective and highly useful for treating textile products such as curtains and masks.

ノロウイルスの不活性化処理に際しては、本発明のノロウイルス不活性化剤を、トリガースプレイヤーやボタン付きディスペンサーを備えたボトルに収容するか、もしくはエアゾールとして、随時、必要に応じて噴霧すればよい。
なお、本発明のノロウイルス不活性化剤の処理量は、1m2あたり化合物Aとして、0.01〜2.0g程度が適当である。

In addition, the treatment amount of the norovirus inactivating agent of the present invention is suitably about 0.01 to 2.0 g as Compound A per 1 m 2 .

次に、具体的な実施例に基づき、本発明のノロウイルス不活性化剤について更に詳細に説明するが、本発明はこれらに限定されるものではない。 Next, the norovirus inactivating agent of the present invention will be described in more detail based on specific examples, but the present invention is not limited thereto.

表1に示す組成の実施品並びに比較品の試験液を作製し、以下の抗ウイルス試験に供した。なお、化合物Bは、塩化ベンザルコニウムである。 Test solutions of the practical products and comparative products having the compositions shown in Table 1 were prepared and subjected to the following antiviral tests. Compound B is benzalkonium chloride.

[試験1:インフルエンザウイルス及びノロウイルスに対するウイルス不活性化試験]
各試験液1mlにウイルス浮遊液0.1mlを滴下し、室温で30分後のウイルス感染価の低下を調べた。ウイルス感染価はウイルス浮遊液を接種した培養細胞の形態変化を観察し、50%組織培養感染量から算出した。
また、ノロウイルスに対する効果は、ノロウイルスに対する代替ウイルスとして広く使用されているネコカリシウイルスを用いた。結果を表2に示す。
[Test 1: Virus inactivation test against influenza virus and norovirus]
0.1 ml of the virus suspension was dropped into 1 ml of each test solution, and the decrease in virus infectivity after 30 minutes at room temperature was examined. The virus infectivity titer was calculated from the 50% tissue culture infectious dose by observing the morphological changes of the cultured cells inoculated with the virus suspension.
Moreover, the effect with respect to a norovirus used the feline calicivirus widely used as an alternative virus with respect to a norovirus. The results are shown in Table 2.

本発明の実施品では、すべて、ノロウイルスに対して効果があり、なかでも、サトウキビ抽出エキスあるいは緑茶抽出エキスを配合した実施品3及び4の効果が高かった。一方、化合物Aを含まないか、あるいは、低濃度しか含有しない比較例1及び3では、ノロウイルスに対して全く無効であった。また、化合物Aを含有しても、エタノールを配合しない比較例2の場合、ノロウイルスに対する不活性化効果は満足のいくものでなかった。 The products of the present invention were all effective against norovirus, and the effects of the products 3 and 4 containing the sugarcane extract or green tea extract were particularly high. On the other hand, Comparative Examples 1 and 3 containing no compound A or containing only a low concentration were completely ineffective against norovirus.
