本発明に使用または供給される電解水等の水溶液は、 有効塩素濃度が、 20〜 1000 p p mであり、 かつ p H 5〜 8の電解水等の水溶液であれば、 その製造 方法は特に限定されず、 アノードと力ソードの間に隔膜を有する電解槽、 または 隔膜を有さなレ、電解槽を用 V、て少量の電解質の溶解した溶液を電気分解する方法 等の公知の方法で製造することができる。 The production method of the aqueous solution such as electrolyzed water used or supplied in the present invention is not particularly limited as long as the effective chlorine concentration is 20 to 1000 ppm and the aqueous solution such as electrolyzed water having a pH of 5 to 8 is used. Using an electrolytic cell with a diaphragm between the anode and the power source, or a method without a diaphragm, using an electrolytic cell, and electrolyzing a solution in which a small amount of electrolyte is dissolved. be able to.
また、 市販等されている次亜塩素酸及び/またはその塩またはその水溶液を、 有効塩素濃度が 20〜： L 000 p pmの範囲になるように希釈し、 11が5〜8 の範囲に入るように調整することによつても得ることができる。 Also, dilute commercially available hypochlorous acid and / or a salt thereof or an aqueous solution thereof so that the effective chlorine concentration is in the range of 20 to: L 000 ppm, and 11 falls in the range of 5 to 8. It can also be obtained by adjusting as described above.
電解水を得る具体的な方法としては、 蒸留水または水道水に塩化ナトリゥムを 0. 2〜0. 8重量0 /0添加した水溶液、 または、 pHが 7〜8の電解水を得るた めに電解によつて生成する酸を中和するために該水溶液にさらに必要量の重炭酸 ナトリゥムまたは水酸化ナトリゥムを添カロし、 アノード側とカソード側の間に隔 膜を有さない無隔膜電解槽を用いて電解する方法を例示することができる。 隔膜を有する電解槽を用いた場合、 陽極側に酸性電解水、 陰極側にアルカリ性 電解水が生成されるので、 必要に応じて両者を混合して p H調整した電解水溶液 を本発明に用いることもできる。 As a specific method for obtaining electrolytic water, distilled water or an aqueous solution Natoriumu chloride in tap water was added from 0.2 to 0.8 weight 0/0, or, in order that pH was obtained electrolyzed water of 7-8 A required amount of sodium bicarbonate or sodium hydroxide is further added to the aqueous solution to neutralize the acid generated by electrolysis, and a non-diaphragm electrolytic cell having no diaphragm between the anode side and the cathode side. Can be exemplified. When an electrolytic cell having a diaphragm is used, acidic electrolyzed water is produced on the anode side and alkaline electrolyzed water is produced on the cathode side. Can also.
本発明に用いられる電解水等の水溶液の有効塩素濃度は、 2 0〜； Ι Ο Ο Ο ρ ρ mの範囲が好ましい。 2 0 p p m未満では、 密閉保存したとしても有効塩素濃度 の低下により使用時に充分な殺菌活性をしめさず、 容器詰めして運搬する場合に 容器本数が増え不便である。 また、 有効塩素濃度が高ければ保存する点では好ま しいが、 1 0 0 0 p p mより高い濃度場合、 運搬、 保存上の安全の問題、 活性ィ匕 剤を添加した際に発熱により一時的に発生する塩素ガス等の酸性ガスの臭気が強 くなるという問題がある。 The effective chlorine concentration of the aqueous solution such as electrolyzed water used in the present invention is preferably in the range of 20 to; Ι Ο Ο ρ ρ m. If it is less than 20 ppm, even if it is stored tightly, it will not have sufficient bactericidal activity at the time of use due to a decrease in the effective chlorine concentration, and the number of containers will be increased when packing and transporting, which is inconvenient. In addition, if the effective chlorine concentration is high, it is preferable to preserve it, but if the concentration is higher than 100 ppm, it is a problem of safety in transportation and storage, and it is temporarily generated due to heat generation when adding an active ingredient. There is a problem that the odor of acidic gas such as chlorine gas becomes stronger.
以上のように調整した電解水等の本発明水溶液を保存する容器としては、 密閉 できるものであれば特に制限されないが、 p Hが 7以下の場合には、 耐酸性を有 する材質の容器、 p Hが 8以上の場合には耐アル力リ性を有する材質の容器を用 いるのが好ましく、 持ち運ぶための重量を考慮した場合に、 樹脂製容器が好まし レ、。 また、容器の容量は、 1度に使用する量によって任意に選択することができ、 例えば、 5 0 0 m 1〜 1 L詰め程度の容量で提供し、 5〜 1 0倍に希釈すれば、 一度に電解水として、 2 L〜： L 0 L程度を調整でき、 個人病院等で治療行為に使 用した 1日分の医療器具の殺菌に使用する場合に、 ある程度充分な量であるとい える。 The container for storing the aqueous solution of the present invention such as electrolyzed water adjusted as described above is not particularly limited as long as it can be sealed, but when the pH is 7 or less, a container made of an acid-resistant material, When the pH is 8 or more, it is preferable to use a container made of a material having resistance to heat resistance, and a resin container is preferable in consideration of the weight for carrying. In addition, the volume of the container can be arbitrarily selected depending on the amount used at a time, for example, if provided in a volume of about 500 m 1 to 1 L packed and diluted 5 to 10 times, 2L ~: L 0L can be adjusted at a time as electrolyzed water. It can be said that it is a sufficient amount when used for sterilization of medical equipment for one day used for medical treatment at private hospitals. .
保存方法は、 有効成分の一つである次亜塩素酸の分解を防ぐため、 冷暗所に保 存するのが好ましく、 紫外線等を遮光するために着色した容器を用いた方が好ま しい場合がある。 The storage method is preferably to store in a cool and dark place in order to prevent the decomposition of hypochlorous acid, which is one of the active ingredients, and it may be preferable to use a colored container to shield ultraviolet rays and the like.
本発明に用いられる電解水等の水溶液中の塩素成分の活性ィ匕を促進する活性ィ匕 剤は、 化学的に安定な型で保存されていた塩素成分を、 殺菌作用がもっとも強く 現れる型に変化させる剤をいう。 なお、 塩素成分とは、 塩素原子を含み、 殺菌効 果を有する化合物群をいい、 具体的には、 次亜塩素酸、 亜塩素酸、 塩素酸、 また は、 それらの無機塩等を例示することができ、 特に、 次亜塩素酸、 次亜塩素酸塩 を好ましく例示することができる。 The activating agent for promoting the activating effect of the chlorine component in an aqueous solution such as electrolyzed water used in the present invention is a type in which the chlorine component stored in a chemically stable form is converted into a type in which the bactericidal action appears most strongly. Refers to an agent that changes. The chlorine component refers to a group of compounds containing a chlorine atom and having a bactericidal effect, and specific examples thereof include hypochlorous acid, chlorous acid, chloric acid, and inorganic salts thereof. In particular, hypochlorous acid and hypochlorite can be preferably exemplified.
上記活性化剤として、 具体的には、 p H調節剤を例示することができ、 特に、 p Hを 1〜3、 好ましくは 1〜2の強酸 I"生にする調整する剤を例示することがで きる。 具体的には、 有機酸、 無機酸等例示することができ、 中でも、 クェン酸、 りん酸、 塩酸等を好ましく例示することができる。 As the activator, specifically, a pH regulator can be exemplified. Examples of the agent that adjusts the pH to 1 to 3, preferably 1 to 2, a strong acid I "can be exemplified. Specific examples include organic acids and inorganic acids. Preferred examples include acids, phosphoric acid, and hydrochloric acid.
調整剤を添加した後の p Hが 1より低い場合には、 塩素成分の分解が速く、 p Hが 3より大きい場合には、 希釈して使用するする際 p Hの上昇が見られ充分な 殺菌効果が得られないというおそれがある。 If the pH after addition of the regulator is lower than 1, the chlorine component is decomposed rapidly, and if the pH is higher than 3, the pH increases when diluted and used. There is a possibility that a bactericidal effect cannot be obtained.
提供する電解水等の本発明水溶液は、 一定の品質管理のもと工業的にある程度 大量に製造され密閉保存されるため、 容器単位で、 活性化剤の必要量をあらかじ め把握することができるので、 一定量の電解水に対して、 必要量の活性化剤を容 器づめして提供することにより、 使用する側は、 p H計等を用いて p Hを管理す る必要がなく、 使用時に両者を混合して希釈するだけで、 殺菌効果の高いしかも 安全な電解水等の本発明水溶液を簡便に入手することができるので好ましい。 上記活性化剤を密閉保存された高有効塩素濃度を有する電解水等の水溶液に添 加する時期は、 実際に使用する前であれば特に制限されないが、 塩素成分は徐々 に分解するため、 使用直前に添加するのが好ましい。 活性化剤を添加後、 特に攪 拌等を行うことなく、 上水で希釈して使用することができる。 The aqueous solution of the present invention such as electrolyzed water to be provided is industrially manufactured in a certain amount in large quantities under a certain quality control and stored tightly, so that it is possible to grasp in advance the required amount of the activator for each container. By providing a required amount of activator in a container for a certain amount of electrolyzed water, the user does not need to control the pH using a pH meter or the like. It is preferable that the aqueous solution of the present invention such as electrolyzed water having a high bactericidal effect and safe can be easily obtained simply by mixing and diluting the two at the time of use. The timing of adding the above-mentioned activator to an aqueous solution such as electrolyzed water having a high effective chlorine concentration which is stored tightly is not particularly limited as long as it is not actually used, but since the chlorine component is gradually decomposed, it is used. It is preferably added immediately before. After the addition of the activator, it can be used after being diluted with tap water without any particular stirring.
本発明の電解水等の水溶液は、 活性剤添加後、 所定温度の水で希釈して用いる ことを特徴とする。 とくに、 従来の電解水製造装置では、 実現か困難であった電 解水等の水溶液の温度調整を、 本発明の使用方法では、 希釈に用いる水の温度を 適度に調整することによって容易に行うことができる。 The aqueous solution of the present invention, such as electrolyzed water, is characterized in that, after the addition of the activator, it is diluted with water at a predetermined temperature before use. In particular, in the method of the present invention, the temperature of an aqueous solution such as electrolytic water is easily adjusted by appropriately adjusting the temperature of the water used for dilution, which is difficult to realize in a conventional electrolytic water production apparatus. be able to.
本発明の水で希釈した後の使用時の電解水等の水溶液中の有効塩素濃度は、 2 〜4 0 p p m、 p Hが 2 . 0〜3 . 0の範囲であるのが好ましい。 有効塩素濃度 が 2 p p m未満では、充分な殺菌効果が得られず、 4 0 p p mを超える濃度では、 生体への刺激性が発現される。 また、 P H 2未満では、 塩素成分の分解が速く、 p H 3を超えると、 前記有効塩素濃度では、 充分な殺菌効果が得られない。 すな わち、 p Hを 2〜 3の比較的低い範囲で使用することにより、 2〜4 0 p p mと いう低い有効塩素濃度でも充分な殺菌効果が得られ、 それ故に、 任意の温度に設 定した水で希釈することによつて多少塩素成分が分解、 揮散したとしても充分な 殺菌効果が得られるため、 本発明のような使用方法が可能になったといえる。 電 解水を所定温度に調整できることにより、 特に、 外気温の低い冬の季節において 電解水等の本発明水溶液を皮膚等の殺菌に用いる場合には、 低い水温による刺激 が少なく効果的に使用することができるといえる。 The effective chlorine concentration in the aqueous solution such as electrolyzed water after use after dilution with the water of the present invention is preferably 2 to 40 ppm, and the pH is preferably in the range of 2.0 to 3.0. If the effective chlorine concentration is less than 2 ppm, a sufficient bactericidal effect cannot be obtained, and if it exceeds 40 ppm, irritation to the living body will be exhibited. Further, it is less than P H 2, fast decomposition of chlorine component, exceeds p H 3, in the effective chlorine concentration, sufficient bactericidal effect. In other words, by using a relatively low pH range of 2-3, a sufficient bactericidal effect can be obtained even at an effective chlorine concentration as low as 2-40 ppm, and therefore, it can be set at any temperature. Even if the chlorine component is decomposed and volatilized to some extent by dilution with constant water, a sufficient bactericidal effect can be obtained, and thus it can be said that the use method as in the present invention has become possible. Electric The ability to adjust the bleeding water to a predetermined temperature enables effective use, especially when the aqueous solution of the present invention such as electrolyzed water is used for disinfection of skin and the like in the winter season when the outside air temperature is low, with little irritation due to low water temperature. It can be said that it can be done.
また、 低い有効塩素濃度で使用できるため、 人体への影響がまったくなく、 電 解水で殺菌後、 水洗い等の別の処理をすることなく、 殺菌されたものを使用する ことができ、 食品であれば、 そのまま食用に供することもできる。 In addition, since it can be used at a low effective chlorine concentration, it has no effect on the human body, and after sterilization with electrolytic water, it can be used sterilized without any other treatment such as washing with water, and it can be used in foods. If available, they can be used as is for food.
また、 本発明の使用方法または供給方法は、 有効塩素濃度が 2 0〜1 0 0 0 p p mでありかつ p H 5〜 8の電解水等の水溶液を容器内に密閉保存し、 使用時ま での間にさらに、あらかじめ次亜塩素酸で処理した香料を添加することもできる。 本発明の電解水等の水溶液は、 器具等の殺菌のみならず、 皮膚、 粘膜または創傷 面の殺菌、 口腔内の殺菌等の医療行為に使用されている。 その場合、 塩素系臭気 の問題が生じる場合がある。 Further, the method of use or supply of the present invention is that an aqueous solution such as electrolytic water having an effective chlorine concentration of 20 to 100 ppm and a pH of 5 to 8 is sealed and stored in a container, and used until the time of use. During the period, a fragrance previously treated with hypochlorous acid can be added. The aqueous solution such as electrolyzed water of the present invention is used not only for sterilization of instruments and the like, but also for medical activities such as sterilization of skin, mucous membrane or wound surface, and sterilization of oral cavity. In that case, the problem of chlorine odor may occur.
このような問題を解決する手段として、 香料を用いることはよく行われるが、 通常使用される香料を前記電解水等の本発明水溶液に添加して使用すると多くの 場合に、 有効塩素成分が香料と反応し、 殺菌効果を著しく低下させるという問題 があった。 この問題に対して、 電気分解法等で生成された有効塩素成分である次 亜塩素酸またはその塩であらかじめ処理された香料を用レ、ることで解決すること ができた。 As a means for solving such a problem, a fragrance is often used. However, when a commonly used fragrance is used by adding it to the aqueous solution of the present invention such as the electrolytic water, the effective chlorine component often becomes a fragrance. And there was a problem that the bactericidal effect was significantly reduced. This problem could be solved by using a perfume pretreated with hypochlorous acid or its salt, which is an effective chlorine component produced by electrolysis or the like.
用いる香料は、 次亜塩素酸またはその塩で処理した場合に香気成分が変質する ものは好ましくないが、 多くのものはこの種の変質が見られない。 具体的には、 ロース、 ラベンダー、 ペパーミント等の香料を用いることができる。 香料の処理 方法は、 例えばアルコール等の水溶性溶媒の香料溶液に、 次亜塩素酸またはその 塩及び酸を添加する方法、 または香料の含まれる電解質含有水溶液を用いて電気 分角军する方法等例示することがきる。 The fragrance used is preferably not one in which the odor component changes when treated with hypochlorous acid or a salt thereof, but many do not show this kind of deterioration. Specifically, flavors such as loin, lavender, and peppermint can be used. The method of treating the fragrance may be, for example, a method of adding hypochlorous acid or a salt thereof and an acid to a fragrance solution of a water-soluble solvent such as alcohol, or a method of performing electrical angle separation using an electrolyte-containing aqueous solution containing the fragrance. It can be illustrated.
以上のように調整された香料を前記した高濃度の電解水等の本発明水溶液、 活 性化剤添加後の電解水等の本発明水溶液、 または希釈後の電解水等の本発明水溶 液に添加して使用することにより、 臭気の問題を解決することができ、 治療に用 いる場合には、 香気成分による治療効果をプラスすることもできる。 The fragrance adjusted as described above is added to the aqueous solution of the present invention such as the above-mentioned high-concentration electrolytic water, the aqueous solution of the present invention such as electrolytic water after adding an activating agent, or the aqueous solution of the present invention such as electrolytic water after dilution. By using it in addition, the problem of odor can be solved, and when used for treatment, the therapeutic effect of the odor component can be added.
本発明の電解水等の水溶液、 または添加用香料には、 必要に応じて他の成分を 添加することもできる。 例えば、 口腔内洗浄用として、 薬用成分であるダルコン 酸クロルへキシン、 フッ化ナトリウム等、 甘味成分としてキシリトール、 保湿剤 としてのグリセリン等を添加することができる。 以下、 本発明を実施例を用いて更に詳細に説明するが、 本亮明は実施例に限定 されるものではない。 実施例 1 The aqueous solution such as electrolyzed water of the present invention, or the flavor for addition may contain other components as necessary. It can also be added. For example, a medicinal ingredient such as chlorhexine dalconate, sodium fluoride, etc., a mouthwash, xylitol as a sweetener, glycerin as a humectant, etc. can be added for washing the mouth. Hereinafter, the present invention will be described in more detail with reference to Examples, but the present invention is not limited to the Examples. Example 1
水道水 4 0 0 O m 1も 1 6 gの塩化ナトリゥムを力 fJえ、 単層平板型電解槽にて 3 0分間通電して電気分解を行つたところ、 P H 7 . 2、 酸化還元電位 5 6 O m V、 活性塩素濃度 2 2 0 p p mの電解水を得た。 これら電解水を 1 0 0 O m 1容 量の角型プラスチック容器に 4本に分注し密栓した。 そのうち、 2本を室温で暗 所に保存し、 表 1に示す各経過日数において 1部を採取し、 希塩酸を用いて p H を調整し水で 1 0倍に希釈した後、 有効塩素濃度、 酸化還元電位を測定した。 そ の結果を表 1にまとめて示す。 比較例 1 Tap water 400 mO1 also applied 16 g of sodium chloride and electrolyzed by applying electricity for 30 minutes in a single-layer flat-type electrolytic cell.PH 7.2, oxidation-reduction potential 5 Electrolyzed water having an active chlorine concentration of 6 O mV and an active chlorine concentration of 220 ppm was obtained. These electrolyzed waters were dispensed into four 100-Om1 square plastic containers and sealed. Two of these were stored in the dark at room temperature, and one part was collected at each elapsed day shown in Table 1, adjusted to pH using dilute hydrochloric acid, and diluted 10 times with water. The oxidation-reduction potential was measured. Table 1 summarizes the results. Comparative Example 1
実施例 1で 1 Lプラスチック容器に分注した電解水に希塩酸を加え p H 2. 2 に調整後、 密栓し、 室温で暗所に保存した。 表 1に示す経過日数において 1部採 取し 1 0倍に希釈した後、 有効塩素濃度、 酸化還元電位を測定した。 その結果を 表 1にまとめて示す。 Dilute hydrochloric acid was added to the electrolyzed water dispensed into the 1-L plastic container in Example 1 to adjust the pH to 2.2, and then sealed and stored at room temperature in a dark place. One part was sampled over the number of days shown in Table 1 and diluted 10-fold, and then the available chlorine concentration and the oxidation-reduction potential were measured. Table 1 summarizes the results.
表 1の結果から、 低い P Hで保存した場合には有効塩素濃度の低下が見られ、 長期保存が困難であるのに対して、 高い： pHで保存した後、 有効塩素濃度に変化 は見られず長期保存が可能であった。 実施例 2 The results in Table 1 show that when stored at low pH, the available chlorine concentration decreased. Long storage is difficult, but high: After storage at pH, there was no change in available chlorine concentration, and long-term storage was possible. Example 2
実施例 1と同様にして製造、 分注して 28曰間保存した後、 希塩酸 （濃塩酸 4 m 1を適当に希釈したもの）を加え、さらに 10倍に希釈して電解水を調整した。 その時の p Hは 2. 6であり、 有効塩素濃度は、 15 p p mであった。 表 2に示 す各菌液 0. 1mlを 0. 9mlの調整した前記電解水で 3分間処理した後、 n u t r i e n t b r o t hで 10倍段階希釈して生菌数を求めた。 尚、 比較の ために電解水未処理区を設けた。 After manufacturing, dispensing and storing for 28 hours in the same manner as in Example 1, diluted hydrochloric acid (appropriately diluted 4 ml of concentrated hydrochloric acid) was added, and further diluted 10 times to prepare electrolytic water. At that time, the pH was 2.6, and the available chlorine concentration was 15 ppm. After 0.1 ml of each bacterial solution shown in Table 2 was treated with 0.9 ml of the adjusted electrolytic water for 3 minutes, the number of viable bacteria was determined by serially diluting the solution with nut triene t b ro th 10 times. For comparison, an electrolyzed water untreated section was provided.
