Bactericidal Compositions Including 3-isothiazolones and glutaraldehyde

摘要

A sterilizing composition comprising 3-isothiazolone and glutaraldehyde, wherein 2-methyl-4-isothiazolone-3-one of formula 1a and 5-chloro-2-methyl-4- of formula 1b Bactericidal compositions comprising 3-isothiazolones and glutaraldehyde in which isothiazolone-3-ones are mixed from 1:20 to 20: 1 are used to control bacteria and fungi in the control of microorganisms in contaminated industrial water and living environments. It is more effective than single compound, superior in instantaneous sterilization and persistence, and because glutaraldehyde and 3-isothiazolone have different mechanisms for killing microorganisms, the effect of lowering the frequency of resistant strains is lowered than when used alone.
