MICROORGANISM CONTROLLER ENHANCED IN DURABILITY OF STERILIZING POWER AND MICROORGANISM CONTROLLING METHOD

摘要

PROBLEM TO BE SOLVED: To provide an improvement method which allows keeping the sterilizing power of 5-chloro-2-methyl-4-isothiazolin-3-one, poly[oxyethylene(dimethyliminio)ethylene(dimethyliminio)ethylene dichloride] or their combination for a long period without frequent re-additions.SOLUTION: A microorganism controller contains 5-chloro-2-methyl-4-isothiazolin-3-one, poly[oxyethylene(dimethyliminio)ethylene(dimethyliminio)ethylene dichloride] and 2-bromo-2-nitropropane-1,3-diol.
