【0007】 消毒薬の分野で使用されている次亜塩素酸ナトリウムは、消毒部位に直接噴霧または浸漬すると、手荒れ等の皮膚への刺激が強く、直接的な使用は好ましくない。次亜塩素酸ナトリウムは、医薬品承認において有効塩素濃度0.01~0.05%(100ppm~500ppm)で使用することが用法用量で定められているが、この濃度は、細胞毒性の出る最小濃度0.001%(10ppm;Japanese Journal of Infectious Diseases Vol.71(2018),No.5 pp.333-337)よりも高く、医薬品としての使用はごく限られた場合に限定されるが、本開示の亜塩素酸水はそのような制約がないことが見出された。消毒薬の分野で使用されているポビドンヨード製剤は、ヨウ素過敏症である場合や、甲状腺機能に問題がある場合には使用は好ましくなく、皮膚の刺激性や、着色(褐変)があり、手術切開前の皮膚の消毒(スワブ法:脱脂綿に含浸させ、清拭)で使用されるのみであるが、本開示の亜塩素酸水はそのような制約がないことが見出された。消毒薬の分野で使用されているアルコール類も皮膚に対して刺激性を有するものであるが、本開示の亜塩素酸水は刺激性が極めて低いことが判明した。また、アルコール類に関しては、皮膚刺激性の他、危険物(第四類アルコール)である為、保管·設置箇所や、場合によっては数量に制限があり、本開示の亜塩素酸水は、ノロウイルスや、アルコール耐性菌に対する消毒効果があるという効果がある。また、アルコールの使用は、ハラームとされるおそれがあり、アルコールを使わないことが求められているが、本開示の亜塩素酸水はそのような制約はない。消毒薬の分野で使用されているベンザルコニウム塩化物(塩化ベンザルコニウム)は、低水準消毒薬であり、一般細菌や酵母様真菌などに有効で、抗菌スペクトルの狭い消毒薬であるが、本開示の亜塩素酸水は、広い抗菌スペクトルに対する消毒効果があることが判明した。
