Microbial countermeasures for water-containing industrial raw materials such as coating color and starch slurry have become important. In order to avoid this microbial damage, various industrial bactericides are used, but 5-chloro-2-, which is effective in terms of both efficacy and stability, is used.
Methyl-4-isothiazolin-3-one (hereinafter abbreviated as CMT) is used in various industrial fields such as adhesives, paints, papers, fibers, and building materials alone or as a mixture with other fungicides. Very often it is added to prevent decomposition of water-containing industrial raw materials such as synthetic resin latex and products. However, the use of the same component does not provide sufficient efficacy because it is resistant to microorganisms that are intended to prevent spoilage, and often the amount of bactericide used increases and the cost often increases. It was Further, methylenebisthiocyanate is known as a bactericide having excellent antibacterial activity and bacteriostatic activity, but when used alone, there is a problem that stability becomes a problem and the efficacy does not last.

組成物である。Means for Solving the Problems As a result of intensive studies to supplement the antibacterial activity of the present inventor, the present inventor has found that CMT-resistant bacteria when methylenebisthiocyanate is used in combination with 1,2-benzisothiazolin-3-one. It has been found that it is also effective against the above-mentioned effects, and that it has an effective effect even for a long period of time when the use of methylenebisthiocyanate alone does not show sufficient antiseptic effect. That is, the present invention is an industrial sterilizing composition containing methylenebisthiocyanate and 1,2-benzisothiazolin-3-one as active ingredients.
