PURPOSE:To obtain an industrial antimicrobial agent composition, composed of a halogenated naphthyl ketone and a specific organic germicide, having excellent antimicrobial activity, capable of exhibiting effects at a lower concentration than that in use of the single ingredients and usable for a long period. CONSTITUTION:An antimicrobial agent composition is obtained by using (A) a halogenated naphthyl ketone, preferably a compound expressed by formula I (R1 is 1-4C halogenoalkyl), especially bromomethyl-1-naphthyl ketone and (B) a germicide selected from (B1) >=3C organohalogen compounds, e.g. 1,4-bis(bromoacetoxy)-2-butene and (B2) organosulfur compounds, e.g. methylene bisthiocyanate, compounds expressed by formula II (X<1> and X<2> are H or halogen), e.g. 4,5-dichlorodithiolan-3-one and compounds expressed by formula III (R<2> is H, methyl or 3-12C hydrocarbon group; X<3> and X<4> are H or halogen), e.g. 1,2-benzisothiazolone in combination at (1:20)-(20:1) weight ratio of the ingredients (A):(B). |
