Description
本発明は、畜産、医療機関、食品工場などにおいて簡便に使用される殺菌消毒剤組成物に関する。 The present invention relates to a disinfectant composition that is easily used in livestock, medical institutions, food factories, and the like.
一般に、畜産、医療機関、食品工場などにおける施設や器具、或いは周辺機器の殺菌消毒に用いられている、例えば、塩化ジデシルジメチルアンモニウム、または、塩化ベンザルコニウムなどの４級アンモニウム塩化合物である殺菌消毒剤は、これらの有効成分を１０％前後含有する水溶液、またはアルコールを含む溶液として市販されているのが通常であり、使用時に用途に応じた希釈倍率で希釈する作業が必要であった。 In general, it is a quaternary ammonium salt compound such as didecyldimethylammonium chloride or benzalkonium chloride, which is used for sterilization and disinfection of facilities, instruments, and peripheral equipment in livestock, medical institutions, food factories, etc. The disinfectant is usually marketed as an aqueous solution containing about 10% of these active ingredients, or a solution containing alcohol, and it is necessary to dilute at a dilution ratio according to the application at the time of use. .
しかしながら、殺菌消毒する対象物によっては、一度に大量の殺菌消毒剤を使用することがあり、この場合、液状の殺菌消毒剤では計量や希釈作業などに困難を来すことがあり、また、使用済みの４級アンモニウム塩化合物溶液の容器の回収に、専門業者による格別の注意と手数を要し、コスト高となるものであった。 However, depending on the object to be sterilized, a large amount of sterilizing agent may be used at one time. In this case, the liquid sterilizing agent may make measurement and dilution work difficult. The collection of the used quaternary ammonium salt compound solution container requires special care and effort by a specialist, which increases the cost.
そこで、従来の不都合を解決するために、液状で提供されていた殺菌消毒剤を粉末化することが考えられ、例えば、塩化ジデシルジメチルアンモニウム溶液を可溶性デンプンで粉末化する技術（例えば特許文献１参照）や、塩化ジデシルジメチルアンモニウム溶液をアルカリ金属塩で固形化する技術（例えば特許文献２参照）が知られている。
解決しようとする問題点は、従来の粉末化法で得られる組成物は、水分含量が比較的高く、計量作業時にべとつきが生じて取り扱い難いものであり、しかも、希釈作業時に組成物が固まりやすい性質を有していることから、組成物の溶解に長時間を要しており、また、従来の固形化法で得られる組成物は、希釈液に沈殿物を生じるため、殺菌消毒用器具の配管などに残滓が詰まるなどのおそれを多分に有していたことである。 The problem to be solved is that the composition obtained by the conventional pulverization method has a relatively high moisture content and is difficult to handle due to stickiness during the weighing operation, and the composition tends to harden during the dilution operation. Because of its properties, it takes a long time to dissolve the composition, and the composition obtained by the conventional solidification method produces a precipitate in the diluted solution. It was that there was a lot of fear that the pipes were clogged with residues.
そこで本発明は、通常水溶液、またはアルコールを含む溶液として市販されている４級アンモニウム塩化合物を有効成分として含有する殺菌消毒剤組成物を高濃度の固形状とすることにより軽量化を図り、運搬保管を容易とすると共に、大量の殺菌消毒剤使用時の容器の回収問題を解決しようとするものである。
しかも、水への溶解性が優れ、残滓が生じることもなく、計量や希釈作業時にべとつきを生じない殺菌消毒剤を得ようとするものである。Therefore, the present invention aims to reduce the weight and transport the disinfectant composition containing a quaternary ammonium salt compound, which is usually marketed as an aqueous solution or a solution containing an alcohol, as an active ingredient in a high concentration solid form. It is intended to facilitate storage and to solve the problem of collecting containers when using a large amount of a disinfectant.
In addition, an object is to obtain a disinfectant having excellent solubility in water, no residue, and no stickiness during weighing and dilution operations.
