PURPOSE:The titled germicide, containing 2,2-dibromo-3-nitrilopropionamide (DBNPA) and/or 2-bromo-2-nitrilopropane-1,3-diol (BNP) and tetrafluoroisophthalonitrile as active constituents, having antimicrobial activity against a wide range of microorganisms and capable of exhibiting improved germicidal effect with a lower concentration than the use of the single agent by the synergistic effect. CONSTITUTION:A nonmedical germicide containing 2,2-dibromo-3- nitrilopropionamide (DBNPA) and/or 2-bromo-2-nitrilopropane-1,3-diol (BNP) and tetrafluoroisophthalonitrile respectively known as antimicrobial agents as active constituents. The compounding weight ratio of the above-mentioned former to the latter is 1:4-4:1. Preferably, a carrier or adjuvant is added to the above-mentioned active constituents and formulated into water-soluble liquid solution, emulsifiable solution, wettable powder, etc., for use. The above- mentioned germicide is used as a slime controlling agent in paper manufacturing process, water treatment slime controlling agent in industrial cooling water system, air conditioning cooling water system, e.g. buildings, etc., preservative in metal working oil, etc. |
