Abstract
Description
本発明は、殺菌消毒剤を含有するウェットワイパーに関する。 The present invention relates to a wet wiper containing a disinfectant.
従来より、第四級アンモニウム塩は防かび剤、防腐剤、消毒剤、脱臭剤として、主として病院及び食品加工場の消毒、繊維、塗料、及び化粧品などの防かび、並びに木材の防腐などに使用されている。
第四級アンモニウム塩の殺菌効果については、次の様に考えられている。第四級アンモニウム塩は陽電荷を有し、菌体の細胞膜は陰電荷を帯びているため、菌体表面に第四級アンモニウム塩が集積する。菌体表面に集積した第四級アンモニウム塩が、菌体タンパク質を変性させることにより、殺菌効果を発揮する。
具体的には、第四級アンモニウム塩の殺菌メカニズムとして、清浄作用や角質溶解作用、乳化作用により、第四級アンモニウム塩は、細胞壁に取り込まれ、細胞膜の表面張力を低下させて殺菌効果を発揮すると考えられている。
Traditionally, quaternary ammonium salts are used as fungicides, preservatives, disinfectants, deodorants, mainly for disinfection of hospitals and food processing plants, fungi such as textiles, paints and cosmetics, and wood preservatives. Has been.
The bactericidal effect of the quaternary ammonium salt is considered as follows. Since the quaternary ammonium salt has a positive charge and the cell membrane of the microbial cell is negatively charged, the quaternary ammonium salt accumulates on the surface of the microbial cell. The quaternary ammonium salt accumulated on the surface of the microbial cell exhibits a bactericidal effect by denaturing the microbial cell protein.
Specifically, as a sterilization mechanism of the quaternary ammonium salt, the quaternary ammonium salt is taken into the cell wall by the cleaning action, keratolysis action, and emulsification action, and exhibits the bactericidal effect by reducing the surface tension of the cell membrane. It is considered to be.
特許文献1及び特許文献2には、第四級アンモニウム塩の不織布基布への吸着を低減する目的で、キレート剤及びアミノ酸型界面活性剤などを含有する殺菌消毒剤が開示されている。 Patent Document 1 and Patent Document 2 disclose a disinfectant containing a chelating agent and an amino acid type surfactant for the purpose of reducing adsorption of a quaternary ammonium salt to a nonwoven fabric base fabric.
しかしながら、一般的にウェットワイパーに使用される、不織布のセルロース成分が負の電荷を帯びているために、第四級アンモニウム塩は吸着されやすく、不織布に均一に含浸できず防かび性を悪化させる原因となっている。特に、ロール巻きの形態であるウェットワイパーにおいて、殺菌消毒剤を含浸させる際に、ロールの下部まで殺菌消毒剤が浸透せずに保存期間中にかびが発生することも少なくない。
また、特許文献1及び特許文献2に開示された殺菌消毒剤においても、第四級アンモニウム塩を均一に含浸させることは困難である。
However, since the cellulose component of the nonwoven fabric, which is generally used for wet wipers, is negatively charged, the quaternary ammonium salt is easily adsorbed and cannot be uniformly impregnated into the nonwoven fabric, thereby deteriorating the antifungal property. It is the cause. In particular, in a wet wiper in the form of a roll, when the sterilizing agent is impregnated, the sterilizing agent does not penetrate to the lower part of the roll, and mold is often generated during the storage period.
Moreover, it is difficult to uniformly impregnate the quaternary ammonium salt even in the disinfectant disclosed in Patent Document 1 and Patent Document 2.
本発明が解決しようとする課題は、殺菌消毒剤を均一に不織布に含浸させ、優れた殺菌性能を有するウェットワイパーを提供することにある。 The problem to be solved by the present invention is to provide a wet wiper having an excellent sterilizing performance by uniformly impregnating a nonwoven fabric with a sterilizing and disinfecting agent.
