Antimicrobial composition based on the synergistic combination of 2-methyl-3-isothiazolone and 1,2-dibromo-2,4-dicyanobutane where the composition is substantially free of halogenated 3-isothiazolone, are disclosed. This combination provides enhanced microbicidal efficacy at a combined active ingredient level lower than that of the combined individual 3-isothiazolone and 1,2-dibromo-2,4-dicyanobutane effective use levels. |
