特許文献1の水解性シートは、原紙シートに薬液を含浸させて製造されている。そして、薬液は、特許文献2の抗菌性組成物の如く、一般的に塩化ベンザルコニウム(第四級アンモニウム塩)を水に溶解させて作製されている。
The water-disintegratable sheet of Patent Document 1 is manufactured by impregnating a base paper sheet with a chemical solution. The drug solution is generally prepared by dissolving benzalkonium chloride (quaternary ammonium salt) in water as in the antimicrobial composition of Patent Document 2.
しかしながら、塩化ベンザルコニウムを水に溶解させて沈澱を生じさせずに所定濃度の水溶液を作製するためには、製造条件をコントロールする必要があることから、通常、塩化ベンザルコニウムは、水に溶解させて水溶液とした上で供給されている。
However, it is usually necessary to control benzalkonium chloride in water, because it is necessary to control the preparation conditions in order to prepare benzalkonium chloride in water and prepare an aqueous solution of a predetermined concentration without causing precipitation. It is supplied after being dissolved to form an aqueous solution.
そのため、塩化ベンザルコニウムの輸送時において、水溶液に含まれる塩化ベンザルコニウム自体の含有量が少量であるにもかかわらず、塩化ベンザルコニウム水溶液の体積及び重量が大きくなり、輸送コスト及び保管コストがかさむという問題点を有している。
Therefore, at the time of transportation of benzalkonium chloride, the volume and weight of the aqueous benzalkonium chloride solution become large despite the small content of benzalkonium chloride itself contained in the aqueous solution, and the transportation cost and the storage cost It has the problem that it takes a long time.
本発明は、沈澱を殆ど生じさせることなく簡単に水に溶解させて薬液を製造することができ、輸送コスト及び保管コストを抑制することができる抗菌性組成物を提供する。
The present invention provides an antimicrobial composition which can be easily dissolved in water to produce a drug solution with little or no precipitation, thereby suppressing transportation and storage costs.
