となる患者への危険性が高まることになる。In recent years, glutaraldehyde has been used as a tanning agent for leather, a crosslinking agent for proteins, an agent for fixing and fixing oxygen, and a developer for photographic film, based on its high reactivity with amine groups, hydroxyl groups, etc. Particularly in recent years, glutaraldehyde has been highly evaluated for its chemical sterilization or disinfection effects against hospital infections caused by various viruses, microspores, and Gram-negative bacteria, such as serum hepatitis and sepsis, and its demand is rapidly increasing. At this time, glutaraldehyde is used as an aqueous solution with a concentration of about 2%, and sodium bicarbonate, etc. is added to increase the bactericidal efficacy, and the pi (pi) of the aqueous solution is adjusted to be slightly alkaline at 75 to 858 degrees. (e.g., U.S. Pat. No. 3 []
See No. 116328. In this way, when the pH of the glutaraldehyde aqueous solution is adjusted to be weakly alkaline, phenomena such as turbidity or precipitation may occur in the aqueous solution if the aqueous solution is left at room temperature or higher temperature flexibility.
often recognized. If a solid substance generated in such an aqueous solution gets mixed into the gap or adheres to the surface of an extremely expensive endoscope or medical equipment such as an endoscope sterilizer, This is very uneconomical as it requires time and labor costs for removal, or the device must be disassembled for repair or discarded if it cannot be removed, and if the deposit remains on the medical device, it poses a danger to the patient for whom the device is being used. Sexuality will increase.
この様な事情からグルタールアルデヒド水溶液を弱アル

本発明者らは今回、グルタールアルデヒド水溶液を弱ア
ルカリ性に調節する時に成る種の物質を同時に添加する
ことにより、水溶液の中に濁りもしくは沈澱が認められ
なくなることを発見した。Due to these circumstances, it has been desired to prevent the occurrence of turbidity or precipitation that is observed when a glutaraldehyde aqueous solution is adjusted to a weak alkalinity. It has been discovered that by simultaneously adding a variety of substances to the aqueous solution, no turbidity or precipitate is observed in the aqueous solution.
従って本発明は弱アルカリ性に調節したグルタールアル
デヒド水溶液中にしばしば認められるで蜀りもしくは沈
澱現象を防止する安定化剤を提供することを目的とする
。Accordingly, an object of the present invention is to provide a stabilizer that prevents the sludge or precipitation phenomenon often observed in aqueous solutions of glutaraldehyde adjusted to be slightly alkaline.
本発明の安定化剤はアルデヒド基と反応性を有する物質
のうち、特にその構造中に亜硫酸基、アミ7基あるいは
水酸基を有する物質の1種または2種以上より成るもの
である。The stabilizer of the present invention is composed of one or more substances having a sulfite group, an amide group, or a hydroxyl group in its structure, among substances that are reactive with aldehyde groups.

上の視点からすれば殺菌効力の低下はほとんど認められ
ない。By adding a substance that reacts with aldehyde groups in this way, the bactericidal efficacy of the glutaraldehyde aqueous solution depends on the glutaraldehyde concentration, so there is a risk that the bactericidal efficacy will decrease. Since the amount added is as low as about 10 to 10% relative to the glutaraldehyde concentration Q, and glutaraldehyde is a bifunctional substance with two aldehyde groups in one molecule, the calculated amount disappears by the reaction. is half of that amount, or about 5%, and from a practical point of view, there is hardly any decrease in bactericidal efficacy.

調節した後に添加する方法がある。In the present invention, the stabilizing agent is added to an aqueous solution of glutaraldehyde in a powdered form, and the pH of the aqueous solution is adjusted to 8.
There is a method in which it is added by first mixing it with sodium hydrogen carbonate or the like to adjust the pH of the aqueous solution to be slightly alkaline, or it is added alone as a stable french after adjusting the pH of the aqueous solution to be slightly alkaline. Alternatively, there is a method in which the pH of the glutaraldehyde aqueous solution is adjusted to weak alkalinity before adding it in solid or liquid form.

るだめ問題とはならない。In the slightly alkaline aqueous glutaraldehyde solution of pH 7.5 to 90 prepared according to the present invention, no phenomenon of turbidity or precipitation was observed even after 3 to 4 weeks at room temperature. If the phenomenon of turbidity or precipitation is not observed in the aqueous solution during this period, the period during which the bactericidal efficacy of the glutaraldehyde aqueous solution is maintained will be exceeded.
Even if there is a possibility that precipitation etc. may be observed after that,
In practical terms, this does not pose a problem since aqueous solutions cannot be used as sterilizing agents.

。100ml of the sample solution in a volume of 100+x? Place it in a glass beaker, cover the beaker with a watch glass, and heat to 40℃.
After being left in an air constant temperature bath set at 4 days, the turbidity of the aqueous solution was measured, and the prevention rate obtained was determined according to the following formula.
即ち、防止率(%)がOもしくは負の直となる場合には
、安定化剤に防止能力の無いことを意味し、100なら
