Description
本発明は、エタノール製剤組成物及びスプレー剤に関する。 The present invention relates to an ethanol pharmaceutical composition and a spray agent.
エタノール80体積%(約74質量%、15℃)溶液のエタノール製剤(消毒用エタノール)は、優れた殺菌力を示し、後処理が容易なことから、食品工場等で汎用されている。エタノール80体積%溶液は、消防法で危険物第4類のアルコール類危険物に該当するので、危険物貯蔵所に保管する等の管理が必要となる。
そこで、エタノール濃度を非危険物である60質量%(約68体積%、15℃)未満のエタノール製剤とすることが望まれている。
Ethanol preparations (ethanol for disinfection) in an 80% by volume (about 74% by mass, 15 ° C.) solution of ethanol show excellent bactericidal activity and are easy to post-treat, and are therefore widely used in food factories and the like. Since the ethanol 80% by volume solution falls under the category of dangerous goods Class 4 alcoholic dangerous goods under the Fire Service Act, it is necessary to manage it by storing it in a dangerous goods storage.
Therefore, it is desired to prepare an ethanol preparation having an ethanol concentration of less than 60% by mass (about 68% by volume, 15 ° C.), which is a non-dangerous substance.
エタノールは、80体積%前後で優れた殺菌力を示すが、エタノール60質量%溶液の殺菌力は80体積%溶液に比べて弱く、エタノール濃度がさらに低下すると殺菌力は極端に低下する。こうした問題に対し、エタノール濃度を50質量%以上60質量%未満として、脂肪酸グリセリンエステル等の添加剤を含む、殺菌剤組成物(エタノール製剤組成物)が開発されている(例えば、特許文献1)。
特許文献1のエタノール製剤組成物によれば、食品、食品製造機器及び食品加工機器に対する殺菌効果の向上が図られている。
Ethanol exhibits excellent bactericidal activity at around 80% by volume, but the bactericidal activity of the 60% by volume ethanol solution is weaker than that of the 80% by volume solution, and the bactericidal activity is extremely reduced when the ethanol concentration is further reduced. To solve these problems, a bactericidal agent composition (ethanol preparation composition) containing an additive such as a fatty acid glycerin ester has been developed with an ethanol concentration of 50% by mass or more and less than 60% by mass (for example, Patent Document 1). ..
According to the ethanol pharmaceutical product composition of Patent Document 1, the bactericidal effect on foods, food manufacturing equipment and food processing equipment is improved.
ところで、まな板等の調理器具は、水道水や食材に由来する水分で濡れた状態となっている。例えば、木製まな板の片面を水道水で洗い流すと、約10gの水分が木製まな板に付着する。木製まな板上に0.5gのエタノール製剤組成物が均一に噴霧されるとすると、約20倍に希釈されたことになる。エタノール製剤組成物が約20倍に希釈されると、殺菌力が著しく低下する。そこで、水分が残留する調理器具や食器に対しても優れた殺菌力を示すエタノール製剤組成物が求められている。 By the way, cooking utensils such as cutting boards are in a state of being wet with tap water or water derived from foodstuffs. For example, when one side of a wooden cutting board is washed away with tap water, about 10 g of water adheres to the wooden cutting board. If 0.5 g of the ethanol preparation composition is uniformly sprayed on a wooden cutting board, it means that the composition is diluted about 20 times. When the ethanol-formulated composition is diluted about 20 times, the bactericidal activity is significantly reduced. Therefore, there is a demand for an ethanol-formulated composition that exhibits excellent bactericidal activity even for cooking utensils and tableware in which water remains.
加えて、肉汁等食材由来の有機物が付着する調理器具においては、ノロウイルス等のウイルス汚染防止が極めて重要である。殺ウイルス剤は有機物の存在によってその効果が低減する。そのため、有機物が存在しても優れた殺ウイルス効果を示すエタノール製剤組成物が求められている。
さらに、エタノール製剤組成物は、低温(例えば、5℃)時に沈殿物を生じる場合がある。エタノール製剤組成物に沈殿物が生じると、スプレーによるエタノール製剤組成物の噴霧が困難となる。冬場の厨房等、低温環境下でエタノール製剤組成物を取り扱うために、エタノール製剤組成物には、低温時に沈殿物が析出しないこと(低温時の液体安定性)が求められている。
In addition, it is extremely important to prevent virus contamination such as norovirus in cooking utensils to which organic substances derived from foodstuffs such as gravy adhere. The effectiveness of virus-killing agents is reduced by the presence of organic matter. Therefore, there is a demand for an ethanol pharmaceutical composition that exhibits an excellent virus-killing effect even in the presence of an organic substance.
In addition, the ethanol pharmaceutical composition may form a precipitate at low temperatures (eg, 5 ° C.). Precipitation of the ethanol-formulated composition makes it difficult to spray the ethanol-formulated composition by spraying. In order to handle the ethanol-formulated composition in a low-temperature environment such as a kitchen in winter, the ethanol-prepared composition is required to have no precipitate (liquid stability at low temperature) at low temperature.
そこで本発明は、低温時の液体安定性に優れ、希釈されても、殺菌力及び殺ウイルス力に優れるエタノール製剤組成物及びこれを充填したスプレー剤を目的とする。 Therefore, an object of the present invention is an ethanol-formulated composition having excellent liquid stability at low temperatures and excellent bactericidal and virus-killing power even when diluted, and a spray agent filled with the same.
本発明者等は、鋭意検討を重ねた結果、特定の脂肪酸グリセリンエステルと特定の有機酸と特定の脂肪酸とを特定の質量比で混合することで、希釈されても、殺菌力及び殺ウイルス力に優れるエタノール製剤組成物を調製できることを見出した。
このエタノール製剤組成物は、低温時の液体安定性に優れ、スプレー剤として好適に用いられることを見出し、本発明に至った。
As a result of diligent studies, the present inventors have conducted a mixture of a specific fatty acid glycerin ester, a specific organic acid, and a specific fatty acid in a specific mass ratio, so that even if diluted, the bactericidal activity and the virus-killing ability are achieved. It has been found that an excellent ethanol preparation composition can be prepared.
It has been found that this ethanol-formulated composition has excellent liquid stability at low temperatures and is suitably used as a spray agent, leading to the present invention.

ウシ胎児血清(シグマハイクロン社、FBS)10体積%及びペニシリンストレプトマイシン溶液(シグマ社)1体積%を含むRoswell Park Memorial Institute 1640培地(シグマ社、以下「RPMI 1640培地」ともいう。)をT-75フラスコ(イワキ社)に15mL添加した。このRPMI 1640培地にネコ腎細胞(ATCC CCL-94)を播種して37℃、炭酸ガス5体積%濃度の雰囲気で培養した。96穴マイクロプレート(イワキ社)について、各ウェルにRPMI 1640培地を0.1mL添加して、ネコ腎細胞を播種して、T-75フラスコの場合と同様に培養した。T-75フラスコで生育したネコ腎細胞にネコカリシウイルス(ATCC VR-782)を感染させて24時間培養して、培養液を得た。この培養液を3000rpmで5分間の遠心分離を行い、上清に肉エキス(ナカライテクス社)10質量%溶液を同量加えて、ウイルス液とした。
各例のエタノール製剤組成物を水で20倍に希釈した試料溶液0.9mLに上記ウイルス液を0.1mL添加して、25℃、10秒放置した。その後、Eagle's Minimal Essential Medium(シグマ社、EMEM培地)で10倍ずつ順次希釈した。96穴マイクロプレートで生育したネコ腎細胞をEMEM培地で洗浄し、希釈した反応液を0.1mL添加して37℃、炭酸ガス5体積%濃度の雰囲気で1時間培養した。1時間培養後の反応液にウシ胎児血清0.2体積%及びペニシリンストレプトマイシン溶液1体積%を含むEMEM培地を0.1mL添加し、37℃、炭酸ガス5体積%濃度の雰囲気で3日間培養した。3日間培養後の細胞の変性を顕微鏡で観察してウイルス感染の有無を判断し、TCID50法にて感染価(log TCID50)を求めた。なお、TCID50法とは、ウイルスに感染すると細胞の形状が変化する現象(細胞変性)を利用したウイルス量の測定法で、「感染価」は、50%の細胞に感染するウイルス量を意味する。感染価が小さいほど、殺ウイルス力に優れる。結果を表3に示す。
表中、「<2.0」は、感染価が2.0(log TCID50)未満であったことを示す。
<Evaluation of virus-killing power>
RPMI 1640 medium (hereinafter also referred to as "RPMI 1640 medium") containing 10% by volume of fetal bovine serum (Sigma Hycron, FBS) and 1% by volume of penicillin streptomycin solution (Sigma) is T-. 15 mL was added to 75 flasks (Iwaki). Cat kidney cells (ATCC CCL-94) were seeded in this RPMI 1640 medium and cultured in an atmosphere at 37 ° C. and a concentration of 5% by volume of carbon dioxide gas. For 96-well microplates (Iwaki), 0.1 mL of RPMI 1640 medium was added to each well, cat kidney cells were seeded, and the cells were cultured in the same manner as in the T-75 flask. Feline calicivirus (ATCC VR-782) was infected with feline kidney cells grown in a T-75 flask and cultured for 24 hours to obtain a culture solution. This culture solution was centrifuged at 3000 rpm for 5 minutes, and the same amount of a 10% by mass solution of meat extract (Nacalai Tesque) was added to the supernatant to prepare a virus solution.
0.1 mL of the above virus solution was added to 0.9 mL of a sample solution obtained by diluting the ethanol pharmaceutical composition of each example 20-fold with water, and the mixture was left at 25 ° C. for 10 seconds. Then, it was sequentially diluted 10-fold with Eagle's Minimal Essential Medium (Sigma, EMEM medium). Cat kidney cells grown on a 96-well microplate were washed with EMEM medium, 0.1 mL of diluted reaction solution was added, and the cells were cultured at 37 ° C. in an atmosphere having a concentration of 5% by volume of carbon dioxide for 1 hour. 0.1 mL of EMEM medium containing 0.2% by volume of fetal bovine serum and 1% by volume of penicillin streptomycin solution was added to the reaction solution after culturing for 1 hour, and the cells were cultured in an atmosphere of 37 ° C. and 5% by volume of carbon dioxide gas for 3 days. .. The presence or absence of virus infection was determined by observing the degeneration of cells after culturing for 3 days under a microscope, and the infectious titer (log TCID 50 ) was determined by the TCID 50 method. The TCID 50 method is a method for measuring the amount of virus using a phenomenon (cell degeneration) in which the shape of cells changes when infected with a virus, and "infection titer" means the amount of virus that infects 50% of cells. do. The smaller the infectious titer, the better the virus-killing power. The results are shown in Table 3.
In the table, "<2.0" indicates that the infectious titer was less than 2.0 (log TCID 50 ).
