Description
【0001】
【産業上の利用分野】
本発明は分岐シクロデキストリン類を配合してなる水に対して安定なイソチアゾロン系化合物含有組成物を提供することに関する。
【0002】
【従来の技術】
産業用水の需要の増加に伴い、再循環用水系の利用が盛んに行われているが、このような利用に際し、微生物の増殖の抑制と制御は重要な問題となってきている。また、これら産業用水以外にも産業資材の多様化に伴い、微生物の増殖による被害、及びかび発生による被害は広範にわたっている。とりわけ、製紙工程で用いられた排水、工業用冷却水、金属加工用潤滑油、水性エマルジョン、あるいは紙、木材、合板、糊、パルプ、繊維などに寄生する菌類、細菌類、酵母、藻類などのへどろ(スライム)問題、微生物被害等についてはその対策が急務とされている。
【0003】
最近、これら微生物の発生を防止し或いはこれらの微生物を除去するための工業用殺菌剤としてイソチアゾロン系化合物が注目され、このイソチアゾロン系化合物はその適用範囲が広く、優れた効果を有することが知られてきている。
【0004】
【発明が解決しようとする課題】
一般に、この種の工業用殺菌剤は液剤であることが好ましいが、これらイソチアゾロン系化合物は、還元性求核体などにより容易に分解することが知られている。そのため、水溶液製剤としては非常に不安定で品質変化が著しく、一方、液剤成分中の有機溶媒の割合を増やすと、消防法との関係において保管上の問題が生ずる等、液剤として安定した製品を供給することが困難であった。
【0005】
そこで製品として長期間安定なイソチアゾロン系化合物を含有する水溶液製剤が求められており、例えば特開昭59−78102号公報、特開昭59−78103号公報、特開昭59−78104号公報、特開昭59−78109号公報、特開昭63−35603号公報、特開昭63−50322号公報等においては水溶液製剤を安定化させるために、金属塩(MXn :Mはマグネシウム、カルシウム、カリウム、銅、鉄、亜鉛、マンガン、銀、コバルト、ニッケル等から選択された金属、Xは塩化物、臭化物、よう化物、硫酸塩、硝酸塩、亜硝酸塩、酢酸塩、過塩素酸塩、重硫酸塩、重炭酸塩、シュウ酸塩、炭酸塩、りん酸塩等から選択された陰イオンを、nは陰イオン、陽イオンの原子価を満たすための整数)による水溶液中のイソチアゾロン系化合物の安定化についての提案がなされている。しかしカルシウム、マグネシウムなどの金属イオンを含むものは対象品に濁りや沈殿を生じさせたりする原因となり好ましくない。特にこれらの金属イオンを含むものをアニオン性高分子系分散物中に添加した場合、共存する金属安定化剤に起因してアニオン性高分子系分散物が不安定になり、擬集物が発生して致命的な問題が生ずる等、上記公報に開示された水溶液製剤は製品としては十分満足できるものではなかった。また、上記以外の従来の金属塩は、安定化剤として十分な安定化効果を有していないか、あるいはマグネシウム塩等と同様な欠点を有しており、やはり製品として満足するものを提供するものではなかった。また特開平5−286815号公報においてはヨウ素酸または臭素酸のアルカリ塩が提案されているが、これら安定化剤は危険物第1類に属し、爆発する危険性があり、取り扱いが非常に難しい。特開平5−247011号公報においてはα、β、γシクロデキストリンを加えて包接化合物をつくり、皮膚刺激性および粘膜刺激性が著しく軽減された組成物が提案されているが、これは粉剤または懸濁剤としての用途に限られていた。

[Industrial applications]
The present invention relates to providing a water-stable isothiazolone-based composition containing a branched cyclodextrin.
[0002]
[Prior art]
With the increase in demand for industrial water, the use of recirculating water systems has been actively pursued. In such use, suppression and control of the growth of microorganisms have become an important problem. In addition to these industrial waters, with the diversification of industrial materials, the damage caused by the growth of microorganisms and the damage caused by mold generation are widespread. In particular, wastewater used in the papermaking process, industrial cooling water, lubricating oil for metalworking, aqueous emulsion, or bacteria, bacteria, yeast, algae, etc., which are parasitic on paper, wood, plywood, glue, pulp, fiber, etc. With regard to the problem of slime (slime), damage to microorganisms, etc., measures are urgently required.
[0003]
Recently, isothiazolone-based compounds have attracted attention as industrial germicides for preventing the generation of these microorganisms or removing these microorganisms, and these isothiazolone-based compounds are widely used and are known to have excellent effects. Is coming.
[0004]
[Problems to be solved by the invention]
Generally, this kind of industrial bactericide is preferably a liquid, but it is known that these isothiazolone compounds are easily decomposed by reducing nucleophiles and the like. Therefore, the quality of the aqueous solution is very unstable and the quality change is remarkable.On the other hand, if the proportion of the organic solvent in the liquid component is increased, a storage problem occurs in relation to the Fire Service Law. It was difficult to supply.
[0005]
Therefore, an aqueous solution containing an isothiazolone compound which is stable for a long period of time is required as a product. For example, JP-A-59-78102, JP-A-59-78103, JP-A-59-78104, and In JP-A-59-78109, JP-A-63-35603, JP-A-63-50322 and the like, in order to stabilize an aqueous solution preparation, a metal salt (MXn: M is magnesium, calcium, potassium, Metals selected from copper, iron, zinc, manganese, silver, cobalt, nickel, etc., X is chloride, bromide, iodide, sulfate, nitrate, nitrite, acetate, perchlorate, bisulfate, An anion selected from bicarbonate, oxalate, carbonate, phosphate, etc., where n is an integer satisfying the valency of the anion or cation) There have been proposals for stabilizing zolone compounds. However, those containing metal ions such as calcium and magnesium are not preferred because they cause turbidity and precipitation of the target product. In particular, when those containing these metal ions are added to the anionic polymer-based dispersion, the anionic polymer-based dispersion becomes unstable due to the coexisting metal stabilizer, and agglomerates are generated. For example, the aqueous solution formulation disclosed in the above publication was not sufficiently satisfactory as a product. In addition, conventional metal salts other than those described above do not have a sufficient stabilizing effect as a stabilizer or have the same drawbacks as magnesium salts and the like, and also provide products that are satisfactory as products. It was not something. Japanese Unexamined Patent Publication (Kokai) No. 5-286815 proposes alkali salts of iodic acid or bromic acid. However, these stabilizers belong to the class 1 dangerous substances, and there is a risk of explosion, which makes handling very difficult. . JP-A-5-247011 proposes a composition in which an inclusion compound is prepared by adding α, β, and γ-cyclodextrin to significantly reduce skin irritation and mucous membrane irritation. It was limited to use as a suspending agent.
[0006]
[Means for Solving the Problems]
In view of the above problems, the present inventors have conducted intensive studies, and as a result, have found that the incorporation of a branched cyclodextrin can stabilize an isothiazolone-based compound in water, and have completed the present invention. That is, the present invention relates to an isothiazolone-based compound-containing composition that is stable to water and contains a branched cyclodextrin, and to providing an aqueous preparation containing an isothiazolone-based compound that is excellent in storage stability and aqueous solution stability.
