Claims the benefit and priority of US Provisional Patent Application No. 61 / 526,149.
本発明は、次亜塩素酸(HOCl)等の次亜ハロゲン酸の安定化溶液および製剤、ならびにその生成および使用のための方法に関する。この溶液は、表面、食品、例えば果物、野菜および作物等、または哺乳動物組織(創傷を含む)を清浄化および/または消毒するための使用が見出される。溶液は、さらに、農産物および切り花の保存における使用が見出される。 The present invention relates to stabilized solutions and formulations of hypohalous acid such as hypochlorous acid (HOCl), and methods for their production and use. This solution finds use for cleaning and / or disinfecting surfaces, foods such as fruits, vegetables and crops, etc., or mammalian tissues (including wounds). The solution will also find use in the preservation of agricultural products and cut flowers.
次亜塩素酸は、感染に抵抗するために人間の体の自然の免疫系により生成される、酸化剤および殺生物剤である。次亜塩素酸は、酸化的バースト経路の最終工程として生成され、大量の次亜塩素酸が食胞内に放出されて、侵入する微生物を破壊する。次亜塩素酸は、表面および原形質膜タンパク質を攻撃し、溶質の輸送および細菌細胞の塩類バランスを損なうことにより、その殺生物作用を発揮する(Pietersonら、Water SA、22(1):43-48(1996))。次亜塩素酸に暴露されたEscherichia coliは、多くの生命系の不活性化により、100ms未満で生存能力を失う(Fairら、40 J. Am. Water Works Assoc. 1051-61(1940))。2.6ppmの次亜塩素酸は、希釈細菌懸濁液中、約5分でE.coliの100%成長阻害をもたらした(Chesneyら、178 J. Bacteriol. 2131-2135(1996))。Chemistry of Water Treatment(第2版)、S.D.FaustおよびO.M.Aly(1998)によれば、5分間で100%死滅させるのに、A.aerogenesに対しては0.08ppm、S.typhosaに対しては0.06ppm、S.dysenteriaeに対しては0.05ppm、およびE.coliに対しては0.03ppmしか必要ない。 Hypochlorous acid is an oxidant and biocide produced by the human body's natural immune system to resist infection. Hypochlorous acid is produced as the final step in the oxidative burst pathway, and large amounts of hypochlorous acid are released into the phagosome to destroy invading microorganisms. Hypochlorous acid exerts its biocidal action by attacking surface and plasma membrane proteins and impairing solute transport and salt balance in bacterial cells (Pieterson et al., Water SA, 22 (1): 43 -48 (1996)). Escherichia coli exposed to hypochlorous acid loses viability in less than 100 ms due to inactivation of many life systems (Fair et al., 40 J. Am. Water Works Assoc. 1051-61 (1940)). 2.6 ppm of hypochlorous acid was found in approximately 5 minutes in a diluted bacterial suspension. resulted in 100% growth inhibition of E. coli (Chesney et al., 178 J. Bacteriol. 2131-2135 (1996)). Chemistry of Water Treatment (2nd edition), S.C. D. Faust and O. M.M. According to Aly (1998), it was found that A. 0.08 ppm for S. aerogenes; 0.06 ppm for S. typhosa 0.05 ppm for dysenteriae, and E. coli. Only 0.03 ppm is required for E. coli.
次亜塩素酸は微生物に対する殺生物剤であるが、人間または動物細胞には著しく毒性ではなく、これは、少なくとも1つには、人間および動物細胞が抗酸化防御系(ADS)として知られる広範囲にわたる極めて効果的な防御メカニズムを有するためである。 Hypochlorous acid is a biocide against microorganisms but is not significantly toxic to human or animal cells, which is, at least in part, a wide range of human and animal cells known as the antioxidant defense system (ADS). This is because it has a very effective defense mechanism.
次亜ハロゲン酸は、例えば創傷のケアおよび管理、医療用もしくは歯科用機器等の硬質表面の消毒、食品の安全性および加工、水処理、ならびに他の工業または農業用途等の、微生物汚染を制御することが重要となる広範な用途を有する。 Hypohalous acid controls microbial contamination, such as wound care and management, disinfection of hard surfaces such as medical or dental equipment, food safety and processing, water treatment, and other industrial or agricultural applications It has a wide range of uses where it is important to do so.
次亜塩素酸の溶液に関連する1つの制限はその安定性であり、これによって、商業的な使用の多くは、比較的即時的な使用のために溶液がオンサイトで作製され得るような状況に制限されている。既存の選択肢には、創傷ケアのためのデーキン液が含まれるが、これは、次亜塩素酸ナトリウム(5.25%)、重炭酸/炭酸ナトリウム(1%)および清浄な水道水を混合することにより調製される希釈次亜塩素酸ナトリウム溶液(0.5%)である。しかしながら、デーキン液は高いpHを有し、したがって、創傷処置において、発疹、掻痒、腫脹、蕁麻疹、および/または水脹れと共に、疼痛および灼熱感をもたらす。さらに、デーキン液は不安定であり、より低いpH(<8.5)における臨床的使用には不適切である。別の選択肢は、Microcyn(商標)溶液である。Microcynは2年の保存期間を有するが、約80ppm(pH7.4)の遊離有効塩素(AFC)の限られたレベル、および殺生物の有効性を制限し得るより低いパーセントの次亜塩素酸が問題である。EcaFlo(商標)は、硬質表面消毒に利用可能である。この溶液は、高い塩化ナトリウム含量に加えて、等モル量の次亜塩素酸塩および次亜塩素酸を含有する。溶液のpHは約7.5であり、溶液は、約460ppmのAFC含量を有する。溶液は、30日という比較的短い保存期間を有する。 One limitation associated with solutions of hypochlorous acid is its stability, which allows many commercial uses in situations where solutions can be made on-site for relatively immediate use. Is limited to. Existing options include Dakin for wound care, which mixes sodium hypochlorite (5.25%), bicarbonate / sodium carbonate (1%) and clean tap water. Dilute sodium hypochlorite solution (0.5%). However, Dakin's solution has a high pH and therefore causes pain and a burning sensation, along with rashes, pruritus, swelling, urticaria, and / or blisters in wound treatment. In addition, Dakin's solution is unstable and unsuitable for clinical use at lower pH (<8.5). Another option is a Microcyn ™ solution. Although Microcyn has a shelf life of 2 years, it has a limited level of free available chlorine (AFC) of about 80 ppm (pH 7.4) and a lower percentage of hypochlorous acid that can limit the effectiveness of biocides. It is a problem. EcaFlo ™ can be used for hard surface disinfection. This solution contains equimolar amounts of hypochlorite and hypochlorous acid in addition to a high sodium chloride content. The pH of the solution is about 7.5 and the solution has an AFC content of about 460 ppm. The solution has a relatively short shelf life of 30 days.
高いAFC含量を有し、十分な安定性ならびに/または医療および他の商業的環境において商業的に有用となるために必要な他の特性を有し、また人間に対し刺激性または有害でない次亜ハロゲン酸溶液の必要性が、未だに満たされていない。特許請求の範囲に記載した本発明は、これらのおよび他の目的を達成する。 Hypoxia with high AFC content, sufficient stability and / or other properties necessary to become commercially useful in medical and other commercial environments, and not irritating or harmful to humans The need for a halogen acid solution has not yet been met. The claimed invention achieves these and other objectives.

For example, sodium bicarbonate has a molar ratio of about 1: 1, about 1: 2, or about 1: 3, or more (ie, more diluted) to AFC content (eg, hypohalous acid content). May be added at levels of In certain embodiments, sodium bicarbonate is incorporated into the solution at a level of about 1: 1 to about 1: 2 relative to the AFC content.

次亜ハロゲン酸溶液は、塩化ナトリウム等のハロゲン化物塩の電気分解により生成されてもよく、また、主に次亜塩素酸および次亜塩素酸ナトリウム等の酸化種の混合物を含んでもよい。次亜塩素酸および次亜塩素酸塩は平衡状態にあり、平衡の位置は、主にpHにより決定される(すなわち、pHが各成分の濃度をもたらす)。pH5.1〜6.0の電気分解された塩化ナトリウム溶液は、約95%以上の次亜塩素酸の純度を有する。したがって、供給される電気分解された溶液は、約4.0〜約7.5のpHを有し得るが、ある特定の実施形態において、約4.4〜約7.0のpH、または約5〜約7のpH、または約5.4〜約6.4のpH、または約5.0〜約6.4のpHを有する。約5.4のpHにおいて、溶液は、次亜塩素酸塩に対してほとんど(100%に近い)次亜塩素酸を含有する。 The hypohalous acid solution may be produced by the electrolysis of a halide salt such as sodium chloride, and may mainly contain a mixture of oxidizing species such as hypochlorous acid and sodium hypochlorite. Hypochlorous acid and hypochlorite are in equilibrium and the position of the equilibrium is mainly determined by the pH (ie, the pH results in the concentration of each component). The electrolyzed sodium chloride solution at pH 5.1-6.0 has a purity of hypochlorous acid of about 95% or more. Thus, the supplied electrolyzed solution may have a pH of about 4.0 to about 7.5, but in certain embodiments a pH of about 4.4 to about 7.0, or about It has a pH of 5 to about 7, or a pH of about 5.4 to about 6.4, or a pH of about 5.0 to about 6.4. At a pH of about 5.4, the solution contains almost (close to 100%) hypochlorous acid relative to hypochlorite.
溶液は、活性薬剤として次亜塩素酸を含むか、または本質的に次亜塩素酸からなってもよく、いくつかの実施形態において、溶液は、他の次亜ハロゲン酸(例えば、HOBr、またはその混合物)を含有してもよい。いくつかの実施形態において、溶液は、中でも次亜ハロゲン酸塩(例えば、次亜塩素酸塩)、水酸化物、H2O2およびO3等の他の酸化種またはラジカル生成種を含有する。 The solution may comprise hypochlorous acid as the active agent or consist essentially of hypochlorous acid, and in some embodiments, the solution may contain other hypohalous acids (eg, HOBr, or A mixture thereof). In some embodiments, the solution contains other oxidizing or radical generating species such as, among others, hypohalite (eg, hypochlorite), hydroxide, H 2 O 2 and O 3. .
溶液の殺生物活性は、遊離有効塩素またはAFCに関して表現することができる。本発明は、約10〜約10,000ppm(または〜約5000ppm)のAFC範囲に適用することができるが、ある特定の実施形態において、溶液は、比較的高いAFC含量を有し、哺乳動物組織または農産物との使用に好適である。例えば、溶液は、約100〜1000ppm、または100〜500ppm、または約150〜約250ppmのAFC含量を有してもよい。他のAFCレベルを使用してもよく、また意図される用途に基づいて選択されてもよい。例えば、限定されないが、表面消毒のために、AFCは、約140〜約2000ppm、または約400〜約1000ppmの範囲であってもよい。 The biocidal activity of the solution can be expressed in terms of free available chlorine or AFC. Although the present invention can be applied to an AFC range of about 10 to about 10,000 ppm (or to about 5000 ppm), in certain embodiments, the solution has a relatively high AFC content and mammalian tissue Or it is suitable for use with agricultural products. For example, the solution may have an AFC content of about 100 to 1000 ppm, or 100 to 500 ppm, or about 150 to about 250 ppm. Other AFC levels may be used and may be selected based on the intended application. For example, without limitation, for surface disinfection, the AFC may range from about 140 to about 2000 ppm, or from about 400 to about 1000 ppm.
次亜塩素酸は、いくつかの実施形態に従い化学的に(例えば、次亜塩素酸塩の酸性化により)生成され得るが、次亜ハロゲン酸はまた、電気化学的にも生成され得る。次亜ハロゲン酸の電気化学的生成は、隔膜式電解槽におけるハロゲン化物系電解質の処理によるものである。食塩水の電気化学的処理は、例えば、参照することによりその全体が本明細書に組み込まれる、米国特許第7,303,660号、米国特許第7,828,942号、および米国特許第7,897,023号に記載されている。 Hypochlorous acid can be produced chemically (eg, by acidification of hypochlorite) according to some embodiments, but hypohalous acid can also be produced electrochemically. The electrochemical production of hypohalous acid is due to the treatment of the halide electrolyte in the diaphragm type electrolytic cell. Electrochemical treatment of saline solution is described, for example, in US Pat. No. 7,303,660, US Pat. No. 7,828,942, and US Pat. No. 7, which are incorporated herein by reference in their entirety. , 897,023.
溶液は、例えばナトリウム、カリウム、カルシウム、またはマグネシウム等のアルカリまたはアルカリ土類金属の重炭酸塩または炭酸塩であってもよい、安定量のDICを使用する。いくつかの実施形態において、重炭酸塩または炭酸塩は、(例えば、電気化学的処理による)次亜ハロゲン酸の形成前に添加され、他の実施形態において、重炭酸塩または炭酸塩は、次亜ハロゲン酸の形成後に溶液に添加される。例えば、重炭酸塩(複数種可)または炭酸塩(複数種可)は、前駆体溶液、電解質、および/または最終溶液に添加されてもよい。 The solution uses a stable amount of DIC, which may be an alkali or alkaline earth metal bicarbonate or carbonate such as, for example, sodium, potassium, calcium, or magnesium. In some embodiments, bicarbonate or carbonate is added prior to the formation of hypohalous acid (eg, by electrochemical treatment), and in other embodiments, bicarbonate or carbonate is It is added to the solution after the formation of halous acid. For example, bicarbonate (s) or carbonate (s) may be added to the precursor solution, electrolyte, and / or final solution.
DICは、経時的な溶液のpHまたはAFC含量の変化に基づき決定され得る「安定量」で組み込まれる。一般に、溶液は、AFCの量が約6ヶ月の期間にわたり初期値の約75%を下回らない場合に、安定化されているとみなされる。ある特定の実施形態において、AFC含量は、溶液の製造日から少なくとも1年間安定化されている。さらに、溶液の安定性は、pHに基づき決定され得る。一般に、溶液は、pHが約6ヶ月の期間にわたり1単位変動しない場合に安定化されているとみなされる。ある特定の実施形態において、pHは、溶液の製造日から少なくとも1年間安定化されている。溶液は、より高い安定性のために、25℃または20℃以下で保管されるべきである。25℃および20℃は、安定性の決定のための基準温度である。安定性試験のために、溶液は、HDPE瓶にパッケージされ、暗所に保管され、未開封で保持される。 The DIC is incorporated in a “stable amount” that can be determined based on changes in solution pH or AFC content over time. In general, a solution is considered stabilized if the amount of AFC does not fall below about 75% of the initial value over a period of about 6 months. In certain embodiments, the AFC content is stabilized for at least one year from the date of manufacture of the solution. Furthermore, the stability of the solution can be determined based on the pH. In general, a solution is considered stabilized if the pH does not vary by 1 unit over a period of about 6 months. In certain embodiments, the pH is stabilized for at least one year from the date of manufacture of the solution. The solution should be stored at 25 ° C. or below 20 ° C. for higher stability. 25 ° C. and 20 ° C. are reference temperatures for stability determination. For stability testing, the solution is packaged in HDPE bottles, stored in the dark and kept unopened.
DIC(例えば添加される炭酸塩または重炭酸塩として)の安定量は、AFC含量に基づき決定され得る。例えば、ある特定の実施形態において、安定量の炭酸塩または重炭酸塩は、AFCレベルに対して約5:1〜1:5のモル比で溶液中に組み込まれる。いくつかの実施形態において、重炭酸塩または炭酸塩は、AFC含量(例えば、次亜塩素酸含量)に対して少なくとも等モル量で溶液中に組み込まれる。さらに他の実施形態において、DIC(例えば、重炭酸塩または炭酸塩)は、AFC含量に対して約5:1、約2:1、約1:1、約1:2、約1:3、または約1:5で組み込まれる。様々な実施形態において、リン酸緩衝液等の他の緩衝成分は使用されないか、または最小限で使用される。例えば、約200ppm〜約500ppmのAFC含量を有する溶液の場合、炭酸塩または重炭酸塩は、溶液を安定化するために、約300mg/L〜約1500mg/Lの量で組み込まれてもよい。ある特定の実施形態において、そのような溶液は、約400〜約1000mg/Lの炭酸塩または重炭酸塩を組み込むことにより安定化される。 The stable amount of DIC (eg as added carbonate or bicarbonate) can be determined based on the AFC content. For example, in certain embodiments, a stable amount of carbonate or bicarbonate is incorporated into the solution in a molar ratio of about 5: 1 to 1: 5 relative to the AFC level. In some embodiments, the bicarbonate or carbonate is incorporated into the solution in at least an equimolar amount relative to the AFC content (eg, hypochlorous acid content). In yet other embodiments, the DIC (eg, bicarbonate or carbonate) is about 5: 1, about 2: 1, about 1: 1, about 1: 2, about 1: 3, relative to the AFC content, Or about 1: 5. In various embodiments, other buffer components such as phosphate buffer are not used or minimally used. For example, in the case of a solution having an AFC content of about 200 ppm to about 500 ppm, carbonate or bicarbonate may be incorporated in an amount of about 300 mg / L to about 1500 mg / L to stabilize the solution. In certain embodiments, such solutions are stabilized by incorporating about 400 to about 1000 mg / L of carbonate or bicarbonate.
理論に束縛されないが、一般に炭酸塩、重炭酸塩、炭酸および溶解CO2を含む溶解無機炭素(DIC)は、本明細書に記載の溶液および組成物が目標とするpH範囲において、低い、または最小限の緩衝能力を提供する。それにもかかわらず、これらの溶液は、溶液および組成物が「要求に応じた」生成に依存しないように、効果的に安定化される。安定化効果は、1つには、それによりHOCLの分解を減速するDICのフリーラジカル捕捉能力に起因し得る。さらに、重炭酸塩が豊富な塩化ナトリウム溶液の電気化学的処理により調製された溶液は(等量の炭酸塩/重炭酸塩で安定化された次亜塩素酸ナトリウムの化学的酸性化とは対照的に)、DICに関連した明確に異なる特性を有し、安定化効果が明確に異なり得る。 Without being bound by theory, in general carbonate, bicarbonate, dissolved inorganic carbon containing carbonate and dissolved CO 2 (DIC), in solution and the pH range in which the composition is targeted as described herein, low, or Provide minimal buffering capacity. Nevertheless, these solutions are effectively stabilized so that the solutions and compositions do not depend on production “on demand”. The stabilizing effect may be due, in part, to the free radical scavenging ability of DIC, thereby slowing down HOCL degradation. In addition, solutions prepared by electrochemical treatment of sodium chloride solution rich in bicarbonate (as opposed to chemical acidification of sodium hypochlorite stabilized with an equivalent amount of carbonate / bicarbonate) In particular, it has distinctly different properties associated with DIC and the stabilization effect can be distinctly different.
いくつかの実施形態において、図5に示されるように、アルカリまたはアルカリ土類金属の重炭酸塩または炭酸塩の添加は、特に高有機負荷の存在下で、微生物または生物膜の処理のための向上した殺生物の有効性を提供する。 In some embodiments, as shown in FIG. 5, the addition of an alkali or alkaline earth metal bicarbonate or carbonate is particularly useful in the presence of high organic loads for the treatment of microorganisms or biofilms. Provides improved biocidal effectiveness.

表面上の細菌胞子および真菌の活性集団を死滅させる、不活性化する、または別様に低減することは、特に困難である。細菌胞子は、増殖期細菌よりも、化学的および物理的な物質の抗菌効果に対してより耐性とする胞子層の独特な化学組成を有する。同様に、真菌細胞、特に黴胞子の独特な化学組成は、他の微生物よりも、化学的および物理的物質に対してより耐性とする。この耐性は、胞子または真菌が、食品、食品接触部位、食器、病院および獣医施設、手術器具、ならびに病院および手術用のリネンおよび衣類等の表面上に存在する場合、特に厄介となり得る。 It is particularly difficult to kill, inactivate, or otherwise reduce the active population of bacterial spores and fungi on the surface. Bacterial spores have a unique chemical composition of the spore layer that makes them more resistant to the antimicrobial effects of chemical and physical substances than vegetative bacteria. Similarly, the unique chemical composition of fungal cells, particularly spore spores, makes them more resistant to chemical and physical substances than other microorganisms. This resistance can be particularly troublesome when spores or fungi are present on surfaces such as food, food contact sites, dishes, hospitals and veterinary facilities, surgical instruments, and hospital and surgical linens and clothing.
黴Chaetomium funicola、およびBacillus種の細菌胞子形成微生物の制御は、とりわけ、食品パッケージングの間、特に食品および飲料製品の低温または高温無菌充填の間、重要となり得る。Bacillus種の微生物は、Bacillus cereus、Bacillus mycoides、Bacillus subtilis、Bacillus anthracis、およびBacillus thuringiensisを含む。これらの後者の微生物は、多くの表現型特性を共有し、高レベルの染色体配列類似性を有し、エンテロトキシン産生微生物として知られる。Bacillus cereusは、環境表面を汚染除去するために使用される殺菌性化学物質に対する増加した耐性を有することが特定されているため、Bacillus cereusは、最も厄介なものの1つである。 Control of bacterial sporulating microorganisms of Chaetomium funicola and Bacillus species can be important, inter alia, during food packaging, especially during cold or hot aseptic filling of food and beverage products. Bacillus species of microorganisms include Bacillus cereus, Bacillus mycoides, Bacillus subtilis, Bacillus anthracis, and Bacillus thuringiensis. These latter microorganisms share many phenotypic characteristics, have a high level of chromosomal sequence similarity and are known as enterotoxin producing microorganisms. Bacillus cereus is one of the most troublesome because it has been identified that it has increased resistance to bactericidal chemicals used to decontaminate environmental surfaces.

図1および2は、2つの環境条件、すなわち低温(C)および室温(R)における、時間の関数としての次亜塩素酸創傷処置溶液のAFCおよびpH測定の5サイクルを示す。示されるように、pHおよびAFC含量の両方が、長期にわたり安定化されなかった。例えば、溶液は、約1週間超の間、安定化されなかった。 Example 1
Stabilized hypochlorous acid solution FIGS. 1 and 2 show five cycles of AFC and pH measurement of hypochlorous acid wound treatment solution as a function of time at two environmental conditions: low temperature (C) and room temperature (R). Indicates. As shown, both pH and AFC content were not stabilized over time. For example, the solution was not stabilized for more than about a week.
溶液を安定化するために、NaCl 4.2g/LおよびNaHCO3 400mg/Lを含む電解質の電気化学的処理により次亜塩素酸を生成した。試料を、pH5.6の重炭酸ナトリウム(NaHCO3)、pH6.7のリン酸二ナトリウム(Na2HPO4)と組み合わせた重炭酸ナトリウム(NaHCO3)、またはpH5.6の重炭酸ナトリウム(NaHCO3)、リン酸二ナトリウムおよび二リン酸ナトリウム(9NaH2PO4:1Na2HPO4)の混合物で緩衝した。AFCを測定する前に、溶液をHDPE瓶内で暗所に1ヶ月保管した。 In order to stabilize the solution, hypochlorous acid was produced by electrochemical treatment of an electrolyte containing NaCl 4.2 g / L and NaHCO 3 400 mg / L. Samples were washed with sodium bicarbonate (NaHCO 3 ) at pH 5.6, sodium bicarbonate (NaHCO 3 ) in combination with disodium phosphate (Na 2 HPO 4 ) at pH 6.7, or sodium bicarbonate (NaHCO 3 ) at pH 5.6. 3 ) buffered with a mixture of disodium phosphate and sodium diphosphate (9NaH 2 PO 4 : 1Na 2 HPO 4 ). The solution was stored in the HDPE bottle for 1 month in the dark before measuring AFC.
図3は、時間の関数としてのAFC降下を示す。結果は、リン酸緩衝液を含有しない溶液は、Na2HPO4緩衝(約25%損失)および9NaH2PO4:1Na2HPO4緩衝溶液(約20%損失)と比較して大幅により安定であった(約8%損失)。 FIG. 3 shows the AFC drop as a function of time. The results show that the solution without phosphate buffer is much more stable compared to Na 2 HPO 4 buffer (about 25% loss) and 9NaH 2 PO 4 : 1Na 2 HPO 4 buffer solution (about 20% loss). (Approximately 8% loss).
時間の関数としての安定化溶液の安定性を試験した。NaCl 4.2g/LおよびNaHCO3 400mg/Lを含む電解質の電気化学的処理により、次亜塩素酸を生成した。溶液は5.3のpH、ゼロ(0)のアルカリ度、および約250ppmのAFCを有していた。この溶液を、HDPE瓶内にパッケージし、暗所に保管した。390日を超える期間にわたり未開封試験瓶におけるpHおよびAFC含量を測定することにより、時間の関数としての溶液の殺生物活性および安定性を試験した。結果を図4に示すが、これは、AFC含量およびpHに関して、1年を超える期間にわたり溶液が安定化されていることを示している。 The stability of the stabilizing solution as a function of time was tested. Hypochlorous acid was generated by electrochemical treatment of an electrolyte containing NaCl 4.2 g / L and NaHCO 3 400 mg / L. The solution had a pH of 5.3, a zero (0) alkalinity, and an AFC of about 250 ppm. This solution was packaged in HDPE bottles and stored in the dark. The biocidal activity and stability of the solution as a function of time were tested by measuring pH and AFC content in unopened test bottles over a period of over 390 days. The results are shown in FIG. 4, which shows that the solution is stabilized over a period of more than one year with respect to AFC content and pH.
一般に、次亜塩素酸ナトリウム溶液は、最初の6ヶ月でその滴定可能な塩素の約20%、および1年以内に最大60%を失うことが、NaOCl製造者により想定されている。ある研究では、50℃および70℃において行われた安定性試験およびアレニウスの式による計算に基づき、20℃における25mg/mLの次亜塩素酸ナトリウム溶液の溶液が20mg/mLの遊離残留塩素に達するのに166日を要することが特定された(Nicolettiら、「Shelf-Life of a 2.5% Sodium Hypochlorite Solution as Determined by Arrhenius Equation」、Braz Dent J (2009) 20(1): 27-31を参照されたい)。他の研究でも同様の結果が示されている(「Product Characteristics, Sodium Hypochlorite-Stability PCH-1400-0007」 PCH-1400-0007-W-EN (WW)、第1号-2005年5月、Solvay Chemicals International SA出版を参照されたい)。これらの想定とは対照的に、特許請求の範囲に記載した本発明のNaHCO3緩衝次亜塩素酸溶液は、1年の期間にわたり1単位未満のpHシフトと共に、滴定可能な塩素の初期レベルの75%超を維持した。 In general, it is assumed by the NaOCl manufacturer that sodium hypochlorite solution loses about 20% of its titratable chlorine in the first 6 months and up to 60% within one year. In one study, a solution of 25 mg / mL sodium hypochlorite solution at 20 ° C. reaches 20 mg / mL free residual chlorine, based on stability tests performed at 50 ° C. and 70 ° C. and calculations with the Arrhenius equation (See Nicoletti et al., “Shelf-Life of a 2.5% Sodium Hypochlorite Solution as Determined by Arrhenius Equation”, Braz Dent J (2009) 20 (1): 27-31). Wanna) Other studies have shown similar results ("Product Characteristics, Sodium Hypochlorite-Stability PCH-1400-0007" PCH-1400-0007-W-EN (WW), No. 1-May 2005, Solvay (See Chemicals International SA publication). In contrast to these assumptions, the claimed NaHCO 3 buffered hypochlorous acid solution of the claimed invention has an initial level of titratable chlorine with a pH shift of less than 1 unit over a period of 1 year. Maintained over 75%.

安定化HOCl溶液の殺生物活性
異なる濃度の次亜塩素酸を含む3種の溶液を生成した。NaCl 4.2g/LおよびNaHCO3 400mg/Lを含む電解質の電気化学的処理により、250ppmの次亜塩素酸を含有する第1の溶液を生成した。同様に電気化学的処理で生成された第2の溶液は、480ppmの次亜塩素酸を含有したが、NaHCO3は含有しなかった。最後の溶液は、480ppmの次亜塩素酸を含有したが、それに加えてNaHCO3 1000mg/Lを組み込んでいた。 (Example 2)
Biocidal activity of stabilized HOCl solutions Three solutions containing different concentrations of hypochlorous acid were produced. Electrochemical treatment of the electrolyte containing NaCl 4.2 g / L and NaHCO 3 400 mg / L produced a first solution containing 250 ppm hypochlorous acid. Similarly, the second solution produced by the electrochemical treatment contained 480 ppm hypochlorous acid but no NaHCO 3 . The last solution contained 480 ppm hypochlorous acid but in addition incorporated 1000 mg / L NaHCO 3 .
最悪の事態をシミュレートするために、高い抗生物質耐性を有する細菌株であるC.difficileの胞子を、ブタからの均質化皮膚細胞、ムチン、およびウシ血清アルブミンからなる高濃縮有機媒体中に懸濁させた。微生物を有機液中に懸濁させた後、それらをプラスチック担体上に植菌し、乾燥させて、0分、4分、6分、8分、10分または30分間、各溶液に2回暴露した。既存の消毒剤のいずれも、この有機負荷(漂白を含む)に耐えられなかったことから、2つの異なる濃度の次亜塩素酸を試験した。 To simulate the worst case, C. a bacterial strain with high antibiotic resistance. difficile spores were suspended in a highly concentrated organic medium consisting of homogenized skin cells from pig, mucin, and bovine serum albumin. After suspending the microorganisms in an organic solution, they are inoculated on a plastic carrier, dried and exposed twice to each solution for 0 min, 4 min, 6 min, 8 min, 10 min or 30 min. did. Since none of the existing disinfectants could withstand this organic load (including bleaching), two different concentrations of hypochlorous acid were tested.
結果(図5)は、重炭酸ナトリウムを含む溶液が、高有機負荷条件下でC.difficile胞子に対するより高い殺生物活性を有することを実証している。 The results (FIG. 5) show that the solution containing sodium bicarbonate is C.I. under high organic loading conditions. It has demonstrated higher biocidal activity against difficile spores.

長期安定性試験
図6は、ポリエチレンテレフタレート(PET)容器内に瓶詰めされ、室温で保管された、目標pH5.4のNaHCO3が豊富なNaCl溶液の電気化学的処理により生成されたHOClの、長期安定性試験の結果を示す。NaHCO3のモル含量は、この製剤中の1モルのHOCl当たり1モルのNaHCO3と等価である。保管期間にわたり、隔月にHOCl安定化溶液の4つの新たな試料を開封し、次いで1ヶ月後に再び開封し、週1回試験した。最初に開封された試料のpHおよびAFCを、最後に開封された、その月の間週1回開封された試料と比較することにより、重炭酸ナトリウムで安定化されたHOClの安定性が確認された。 (Example 3)
Long-Term Stability Test FIG. 6 shows the long-term stability of HOCl produced by electrochemical treatment of a NaCl solution rich in NaHCO 3 with a target pH of 5.4, bottled in polyethylene terephthalate (PET) containers and stored at room temperature. The result of a stability test is shown. Molar content of NaHCO 3 is equivalent to NaHCO 3 in 1 mole per mole of HOCl in this formulation. Over the storage period, four new samples of HOCl stabilizing solution were opened every other month, then opened again after one month and tested once a week. The stability of HOCl stabilized with sodium bicarbonate was confirmed by comparing the pH and AFC of the first opened sample with the last opened sample once a week for the month. It was.

添加された重炭酸ナトリウムによるHOClの安定性
乾燥重炭酸ナトリウムを含む容器に加えられたHOClの安定性を、図7Aおよび7Bに示す。イオン強度または溶液塩分は、重炭酸ナトリウムの添加により影響されなかった。結果は、安定剤としての重炭酸塩が、pHおよびAFC安定性の両方に影響することを実証している。いかなる理論にも束縛されないが、pHが約5.5であり、重炭酸塩の緩衝能力が最小限である場合、重炭酸塩は、1つには次亜塩素酸の解離により生成されるフリーラジカルを捕捉することにより、安定剤として作用し得る。その結果、pHおよびAFCの経時的な降下は最小限である。 Example 4
Stability of HOCl with added sodium bicarbonate The stability of HOCl added to a vessel containing dry sodium bicarbonate is shown in FIGS. 7A and 7B. Ionic strength or solution salinity was not affected by the addition of sodium bicarbonate. The results demonstrate that bicarbonate as a stabilizer affects both pH and AFC stability. Without being bound by any theory, when the pH is about 5.5 and the buffering capacity of the bicarbonate is minimal, the bicarbonate is partly free produced by the dissociation of hypochlorous acid. By scavenging radicals, it can act as a stabilizer. As a result, the pH and AFC drop over time is minimal.
(実施例5)
農業用途のHOCl組成物の安定性
電気化学的に生成され、さらに目標pHのためにリン酸二ナトリウムおよび一ナトリウムで緩衝された次亜塩素酸溶液(農業用途における実用性を有する)におけるpHおよび溶液安定性に対するDIC含量の効果を、図8に示す。リン酸塩添加剤を含む次亜塩素酸の組成物を、重炭酸塩あり、およびなしで試験した。結果は、リン酸塩単独よりも、重炭酸塩の存在下で次亜塩素酸がより良好に安定であることを示した。DICおよびリン酸緩衝液の組合せは、全溶解固形分を著しく増加させることなく、より良好な溶液安定性を提供した。 (Example 5)
Stability of HOCl compositions for agricultural applications pH in hypochlorous acid solutions (with utility in agricultural applications) that are electrochemically generated and buffered with disodium and monosodium phosphate for the target pH and The effect of DIC content on solution stability is shown in FIG. Hypochlorous acid compositions containing phosphate additives were tested with and without bicarbonate. The results showed that hypochlorous acid was better stable in the presence of bicarbonate than phosphate alone. The combination of DIC and phosphate buffer provided better solution stability without significantly increasing total dissolved solids.

ヒドロゲル製剤
安定化次亜塩素酸溶液を含有する、ヒドロゲル製剤を開発した。本発明による重炭酸塩または溶解無機炭素の使用は、溶液のイオン強度または電気伝導率に対し最小限の影響を有するにすぎない。したがって、約4〜約7.5のpH範囲(例えば約6.0)でHOCl溶液を安定化することに加えて、重炭酸塩または炭酸塩は、目標pHにおいてイオン強度に影響せず、特に低イオン強度が製剤に重要である場合に、ゲル製剤中の分散媒体としての200ppmを超える遊離有効塩素を有する次亜塩素酸の使用を可能にする。 (Example 6)
Hydrogel formulation A hydrogel formulation containing a stabilized hypochlorous acid solution was developed. The use of bicarbonate or dissolved inorganic carbon according to the present invention has only a minimal effect on the ionic strength or electrical conductivity of the solution. Thus, in addition to stabilizing the HOCl solution in a pH range of about 4 to about 7.5 (eg, about 6.0), bicarbonate or carbonate does not affect ionic strength at the target pH, especially When low ionic strength is important to the formulation, it allows the use of hypochlorous acid with more than 200 ppm free available chlorine as the dispersion medium in the gel formulation.
低イオン強度次亜塩素酸溶液(伝導率≦1mS/cm(すなわち、センチメートル当たりのミリジーメンス))、AFC=300ppm、pH5.3を、3%のフルオロケイ酸ナトリウムマグネシウムを含有するヒドロゲル製剤に使用した。等しいpHおよびAFC含量を有する8mS/cmのHOClから作製された等しい粘度のヒドロゲルを生成するには、4%を超えるフルオロケイ酸ナトリウムマグネシウムが必要であった。分散媒体としてのより低いイオン強度のHOCl溶液は、物理的外観および生成物安定性に悪影響を及ぼすことのない、最終生成物におけるpH最適化のための他の緩衝剤の添加を可能にする。ゲル化剤は、それ自体乾燥した緩衝剤であることから、最終生成物におけるpH最適化のための他の緩衝剤を添加する能力は有益となり得る。 Low ionic strength hypochlorous acid solution (conductivity ≦ 1 mS / cm (ie, milliSiemens per centimeter)), AFC = 300 ppm, pH 5.3 to a hydrogel formulation containing 3% sodium magnesium fluorosilicate used. Over 4% sodium magnesium fluorosilicate was required to produce an equal viscosity hydrogel made from 8 mS / cm HOCl with equal pH and AFC content. The lower ionic strength HOCl solution as the dispersion medium allows the addition of other buffers for pH optimization in the final product without adversely affecting the physical appearance and product stability. Since the gelling agent is itself a dry buffer, the ability to add other buffers for pH optimization in the final product can be beneficial.
別の例において、次亜塩素酸溶液、AFC350ppm、pH5.3、塩分4g/l(伝導率8mS/cm)を、4%のF12MgNa2Si2(フルオロケイ酸ナトリウムマグネシウム)を含有するヒドロゲルの生成に使用した。生成されたヒドロゲルは、330センチポアズ(cP)の粘度および8.2のpHを有していた。pHを「皮膚に優しい」範囲とするために、緩衝剤としてリン酸を添加した。図9に見られるように、最終ヒドロゲルは、pH6から6.8への経時的なpHシフトを有していた。追加的な緩衝剤は、粘度が10mS/cmへの伝導率の増加と共に220cPにシフトするため、ゲル粘度により制限される。 In another example, a hydrogel containing hypochlorous acid solution, AFC 350 ppm, pH 5.3, salinity 4 g / l (conductivity 8 mS / cm), 4% F 12 MgNa 2 Si 2 (sodium magnesium fluorosilicate) Used to generate The resulting hydrogel had a viscosity of 330 centipoise (cP) and a pH of 8.2. Phosphoric acid was added as a buffer to bring the pH into the “skin-friendly” range. As can be seen in FIG. 9, the final hydrogel had a pH shift over time from pH 6 to 6.8. The additional buffering agent is limited by the gel viscosity as the viscosity shifts to 220 cP with increasing conductivity to 10 mS / cm.
実質的に米国特許第7,897,023号(参照することにより本明細書にその全体が組み込まれる)に記載のように、低イオン強度の次亜塩素酸、AFC=370ppmを、塩化ナトリウムの電気化学的処理により生成し、溶解無機炭素(DIC)の初期形態として500ppmのNaHCO3に等しい乾燥重炭酸ナトリウムを有する容器内に採取した。このプロセスにより生成された、pH5.2および伝導率0.8mS/cmのHOClは、ゲル調製のための分散媒体であり、また分散媒として使用された。3%のフルオロケイ酸ナトリウムマグネシウムは、ゲル化剤として使用された。ヒドロゲルは、8.4の初期pHおよび約1mS/cmの伝導率で、約10,000cPの粘度で25分未満に形成した。ヒドロゲルのpHを皮膚に優しい範囲(約pH5.5〜5.8)に低下させるために、リン酸を0.25%未満の量で添加した。2,000cPを超える粘度を有するヒドロゲルが形成された。 Low ionic strength hypochlorous acid, AFC = 370 ppm, of sodium chloride, substantially as described in US Pat. No. 7,897,023 (incorporated herein by reference in its entirety). It was produced by electrochemical treatment and collected in a container with dry sodium bicarbonate equal to 500 ppm NaHCO 3 as the initial form of dissolved inorganic carbon (DIC). HOCl produced by this process with a pH of 5.2 and a conductivity of 0.8 mS / cm was the dispersion medium for gel preparation and was used as the dispersion medium. 3% sodium magnesium fluorosilicate was used as the gelling agent. The hydrogel formed in less than 25 minutes with a viscosity of about 10,000 cP with an initial pH of 8.4 and a conductivity of about 1 mS / cm. Phosphoric acid was added in an amount of less than 0.25% in order to lower the pH of the hydrogel to a skin-friendly range (about pH 5.5-5.8). A hydrogel having a viscosity greater than 2,000 cP was formed.
