Description

本発明は、酸性電解水およびその製造方法、ならびに該酸性電解水を含む洗浄剤および殺菌剤に関する。   The present invention relates to acidic electrolyzed water and a method for producing the same, and a cleaning agent and a disinfectant containing the acidic electrolyzed water.

酸性電解水は、水と、塩化ナトリウムや塩酸等の電解質の溶液を電気分解して得られる電解水である。pH値が2.7以下の酸性電解水は一般に「強酸性水」と呼ばれ、強い殺菌作用を有することが知られている(特許文献1)。   The acidic electrolyzed water is electrolyzed water obtained by electrolyzing water and an electrolyte solution such as sodium chloride or hydrochloric acid. Acidic electrolyzed water having a pH value of 2.7 or lower is generally called “strongly acidic water” and is known to have a strong bactericidal action (Patent Document 1).

しかしながら、強酸性水は通常、殺菌力の保持期間が短いため、長期間の保存が困難である。また、強酸性水は浸透圧が低いため、例えば傷口の洗浄に使用すると、浸透圧の違いに起因して細胞にダメージを与えてしまう。   However, strong acidic water usually has a short sterilizing power retention period and is difficult to store for a long time. Moreover, since strongly osmotic water has a low osmotic pressure, for example, when used for cleaning wounds, the cells are damaged due to the difference in osmotic pressure.

図1は、本発明の酸性電解水における化学平衡式を示している。本発明の酸性電解水中では、図1の式(a)が平衡を保っている。また、塩化水素(HCl)は、図1の式(a)と図1の式(b)との間で矢印(1)および(2)にて平衡を保っており、次亜塩素酸(HClO)は、図1の式(a)と図1の式(c)との間で矢印(3)および(4)にて平衡を保っている。塩化水素は極めて強い酸であるので電離しやすく、矢印(2)が優位である。一方、次亜塩素酸は塩化水素の影響を受けてほとんど電離しないため、矢印(3)が優位である。   FIG. 1 shows a chemical equilibrium formula in the acidic electrolyzed water of the present invention. In the acidic electrolyzed water of the present invention, the equation (a) in FIG. 1 is kept in equilibrium. In addition, hydrogen chloride (HCl) is balanced between the formula (a) in FIG. 1 and the formula (b) in FIG. 1 by arrows (1) and (2), and hypochlorous acid (HClO ) Is balanced at the arrows (3) and (4) between the equation (a) in FIG. 1 and the equation (c) in FIG. Since hydrogen chloride is a very strong acid, it is easily ionized and the arrow (2) is dominant. On the other hand, since hypochlorous acid is hardly ionized under the influence of hydrogen chloride, the arrow (3) is dominant.

例えば、有効塩素濃度が50ppmである本実施形態に係る酸性電解水の浸透圧を285±50mOsmに調整するためには、例えば、無機酸がホウ酸の場合、ホウ酸の含有量は、14〜20.2g/Lであることが好ましく、無機塩がリン酸二水素ナトリウムの場合、含有量は15.7〜22.6g/Lであることが好ましく、無機塩がピロリン酸二水素二ナトリウムの場合、含有量は20.8〜31.0g/Lであることが好ましく、無機塩がヘキサメタリン酸ナトリウムの場合、含有量は60.5〜95.5g/Lであることが好ましい。   For example, in order to adjust the osmotic pressure of the acidic electrolyzed water according to this embodiment having an effective chlorine concentration of 50 ppm to 285 ± 50 mOsm, for example, when the inorganic acid is boric acid, the content of boric acid is 14 to It is preferably 20.2 g / L. When the inorganic salt is sodium dihydrogen phosphate, the content is preferably 15.7 to 22.6 g / L. The inorganic salt is disodium dihydrogen pyrophosphate. In this case, the content is preferably 20.8 to 31.0 g / L. When the inorganic salt is sodium hexametaphosphate, the content is preferably 60.5 to 95.5 g / L.

無機酸および無機塩は、本実施形態に係る酸性電解水を所定のpH値(例えばpH値3.0以上かつ7.0未満)に調整しやすい点で、弱酸性(例えばpH値3.0以上かつ7.0未満)であることが好ましい。本発明において、「弱酸性」とは、水に溶解させたときの水溶液が3.0以上かつ7.0未満のpH値を示すものをいう。   The inorganic acid and the inorganic salt are weakly acidic (for example, a pH value of 3.0) because the acidic electrolyzed water according to the present embodiment is easily adjusted to a predetermined pH value (for example, a pH value of 3.0 or more and less than 7.0). Above and below 7.0). In the present invention, “weakly acidic” means that the aqueous solution when dissolved in water exhibits a pH value of 3.0 or more and less than 7.0.

弱酸性無機酸および弱酸性無機塩は、水に溶解させたときの水溶液が3.0以上かつ7.0未満のpH値を示す。このため、本実施形態に係る酸性電解水が、弱酸性無機酸および/または弱酸性無機塩を含むことにより、該酸性電解水のpH値を、本実施形態に係る酸性電解水を調製する際のpH値の制御が容易である。   A weakly acidic inorganic acid and a weakly acidic inorganic salt have a pH value of an aqueous solution of 3.0 or more and less than 7.0 when dissolved in water. For this reason, when the acidic electrolyzed water according to the present embodiment contains a weakly acidic inorganic acid and / or a weakly acidic inorganic salt, the pH value of the acidic electrolyzed water is adjusted when the acidic electrolyzed water according to the present embodiment is prepared. It is easy to control the pH value.

弱酸性無機酸としては、例えば、ホウ酸が挙げられ、弱酸性無機塩としては、例えば、ピロリン酸二水素二ナトリウム、ヘキサメタリン酸ナトリウムが挙げられる。   Examples of the weakly acidic inorganic acid include boric acid, and examples of the weakly acidic inorganic salt include disodium dihydrogen pyrophosphate and sodium hexametaphosphate.

なお、有効塩素濃度を低下させないため、無機酸および/または無機塩は、塩化物でないことが好ましい。無機酸および/または無機塩が塩化物であると、酸性電解水中の塩化物イオン濃度が高くなる結果、図1の式(a)における平衡が左に偏り、酸性電解水から塩素が気体として蒸発するため、酸性電解水中の有効塩素濃度が低くなることがある。   In order not to reduce the effective chlorine concentration, the inorganic acid and / or the inorganic salt is preferably not a chloride. If the inorganic acid and / or the inorganic salt is chloride, the chloride ion concentration in the acidic electrolyzed water increases, and as a result, the equilibrium in the equation (a) in FIG. 1 is biased to the left, and chlorine evaporates from the acidic electrolyzed water as a gas. Therefore, the effective chlorine concentration in the acidic electrolyzed water may be lowered.

また、本実施形態に係る酸性電解水を歯磨き粉、口腔内洗浄剤等の歯科用洗浄剤に配合する場合、歯石の再付着を防止することができる点で、無機塩はピロリン酸二水素二ナトリウムであることが好ましい。この場合、有効塩素濃度が50ppmである本実施形態に係る酸性電解水中のピロリン酸二水素二ナトリウムの含有量が20.8〜31.0g/Lであることにより、長期間(少なくとも3週間以上、例えば約6か月以上)にわたって殺菌力を持続でき、かつ、歯石の再付着を防止できる。なお、本実施形態に係る酸性電解水は、本実施形態に係る酸性電解水の性質に影響を生じない範囲で、無機酸および/または無機塩以外の成分を含んでいてもよい。   In addition, when the acidic electrolyzed water according to the present embodiment is blended with a dental detergent such as a toothpaste or an intraoral cleaner, the inorganic salt is disodium dihydrogen pyrophosphate in that it can prevent reattachment of tartar. It is preferable that In this case, when the content of disodium dihydrogen pyrophosphate in the acidic electrolyzed water according to this embodiment having an effective chlorine concentration of 50 ppm is 20.8 to 31.0 g / L, a long period (at least 3 weeks or more) Sterilizing power can be maintained over a period of, for example, about 6 months or more, and calculus reattachment can be prevented. In addition, the acidic electrolyzed water according to the present embodiment may contain components other than the inorganic acid and / or the inorganic salt as long as the properties of the acidic electrolyzed water according to the present embodiment are not affected.

また、本実施形態に係る酸性電解水を医薬品、食品、化粧品等に配合する場合、保湿効果を有する点で、無機塩はヘキサメタリン酸ナトリウムであることが好ましい。   Moreover, when mix | blending the acidic electrolyzed water which concerns on this embodiment with a pharmaceutical, a foodstuff, cosmetics, etc., it is preferable that an inorganic salt is sodium hexametaphosphate at the point which has a moisturizing effect.

さらに、本実施形態に係る酸性電解水を医薬品(例えば、洗眼薬、目薬)、化粧品(例えば、入浴剤)等に配合する場合、殺菌作用を有する点で、無機酸はホウ酸であることが好ましい。   Furthermore, when the acidic electrolyzed water according to the present embodiment is blended in a pharmaceutical (for example, eye wash, eye drops), cosmetics (for example, bathing agent) or the like, the inorganic acid may be boric acid in that it has a bactericidal action. preferable.

1.5.塩素系電解質の含有量
本実施形態に係る酸性電解水は、金属の腐食を抑えることができ、かつ、本実施形態に係る酸性電解水から塩素ガスが遊離するのを抑えることができる観点から、塩素系電解質の含有量が塩化ナトリウム換算で0.1質量%以下であることが好ましく、塩化ナトリウム換算で0.05質量%以下であることがより好ましい。本実施形態に係る酸性電解水において、塩素系電解質の含有量(添加量)が塩化ナトリウム換算で0.1質量%を超えると、塩化物イオンと該酸性電解水に含まれる水素イオンとが結合する結果、図1に示される式(a)と式(b)との平衡が矢印(1)の方向に偏り、そして、図1に示される式(a)の平衡が左に偏る。その結果、塩化物イオンが塩素として系外に放出されることにより、該酸性電解水の有効塩素濃度が低下して、殺菌効果が低減することがある。
1.5. Content of chlorine-based electrolyte From the viewpoint that the acidic electrolyzed water according to the present embodiment can suppress the corrosion of the metal and can suppress the release of chlorine gas from the acidic electrolyzed water according to the present embodiment. The content of the chlorine-based electrolyte is preferably 0.1% by mass or less in terms of sodium chloride, and more preferably 0.05% by mass or less in terms of sodium chloride. In the acidic electrolyzed water according to the present embodiment, when the content (addition amount) of the chlorine-based electrolyte exceeds 0.1% by mass in terms of sodium chloride, chloride ions and hydrogen ions contained in the acidic electrolyzed water are combined. As a result, the balance between the formula (a) and the formula (b) shown in FIG. 1 is biased in the direction of the arrow (1), and the balance of the formula (a) shown in FIG. 1 is biased to the left. As a result, when chloride ions are released out of the system as chlorine, the effective chlorine concentration of the acidic electrolyzed water may be reduced, and the bactericidal effect may be reduced.

本実施形態に係る酸性電解水は、塩素系電解質を実質的に含まないことがより好ましい。なお、「本実施形態に係る酸性電解水は、塩素系電解質を実質的に含まない」とは、実施形態に係る酸性電解水における塩素系電解質の濃度が0.025質量%であることをいい、例えば、実施形態に係る酸性電解水塩素系電解質が配合されていないことをいう。   More preferably, the acidic electrolyzed water according to the present embodiment does not substantially contain a chlorine-based electrolyte. Note that “the acidic electrolyzed water according to the present embodiment does not substantially contain the chlorine-based electrolyte” means that the concentration of the chlorine-based electrolyte in the acidic electrolyzed water according to the embodiment is 0.025 mass%. For example, it means that the acidic electrolyzed water-based electrolyte according to the embodiment is not blended.

本発明において、「塩素系電解質」とは、水に溶解すると塩化物イオンを生じる電解質のことをいう。塩素系電解質としては、例えば、アルカリ金属の塩化物(例えば、塩化ナトリウム、塩化カリウム)、アルカリ土類金属(例えば、塩化カルシウム、塩化マグネシウム)の塩化物が挙げられる。   In the present invention, the “chlorine-based electrolyte” refers to an electrolyte that generates chloride ions when dissolved in water. Examples of the chlorine electrolyte include chlorides of alkali metals (for example, sodium chloride and potassium chloride) and alkaline earth metals (for example, calcium chloride and magnesium chloride).

また、一般に、有機酸や有機酸の塩等の有機物が酸性電解水中に存在すると、該有機物が塩素により酸化されて塩素が消費される結果、殺菌力が低下することがある。これに対して、無機酸の酸性塩は有機物でないため、塩素による酸化を受け難いので、殺菌力を長期間にわたって保持することができる。特に、本実施形態に係る酸性電解水が有機物を実質的に含まない場合、酸化力を長期間にわたって保持することができる。   In general, when an organic substance such as an organic acid or a salt of an organic acid is present in the acidic electrolyzed water, the organic substance may be oxidized by chlorine and consumed, resulting in a decrease in sterilizing power. On the other hand, since the acidic salt of an inorganic acid is not an organic substance, it is difficult to be oxidized by chlorine, so that the bactericidal power can be maintained for a long time. In particular, when the acidic electrolyzed water according to this embodiment does not substantially contain an organic substance, the oxidizing power can be maintained for a long period of time.
