Synergistic microbicidal compositions containing N-(n-butyl)-1,2-benzisothiazolin-3-one or N-methyl-1,2-benzisothiazolin-3-one.

Microbicidal composition

A method for reducing antimicrobial compound levels in a liquid composition containing at least one antimicrobial compound. The method comprises contacting said liquid composition with a functionalized resin. Antimicrobial compounds that may be removed by this method include isothiazolin-3-ones, e.g., 2-methyl-4-isothiazolin-3-one; 5-chloro-2-methyl-4-isothiazolin-3-one; 2-n-octyl-4-isothiazolin-3-one; 4,5-dichloro-2-n-octyl-4-isothiazolin-3-one; 1,2-benzisothiazolin-3-one and N-alkyl derivatives thereof, especially N-methyl and N-n-butyl; 2,2-dibromo-3-nitrilopropionamide (DBNPA); 2-bromo-2-nitropropanediol (BNPD); dithio-2,2'-bis(benzmethylamide) (DTBMA); hexetidine; chlorphenesin, C-Calkyl-4-hydroxybenzoates (alkyl parabens); 3-iodopropynylbutylcarbamate (IPBC); formaldehyde releasers and mixtures thereof.

Reduction of antimicrobial compound levels during product dispensing

Synergistic microbicidal compositions containing N-methyl-1,2-benzisothiazolin-3-one.

A microbicidal composition of 1,2-benzisothiazolin-3-one; and at least one of benzalkonium chloride, benzethonium chloride, benzyl alcohol, caprylyl glycol, chlorphenesin, diazolidinyl urea, ethylparaben, imidazolidinyl urea, methylparaben, phenoxyethanol, linoleamidopropyl PG-dimonium chloride phosphate, cocamidopropyl PG-dimonium chloride phosphate, propylparaben, cis-1-(3-chloroallyl)-3,5,7-triaza-1-azoniaadamantane chloride, dehydroacetic acid or its salts, benzoic acid or its salts, and sodium hydroxymethylglycinate.
