Antimicrobial system and method

Abstract

An antimicrobial system comprising (a) an antimicrobial compound according to Formula I (I) and (b) a stabilised chlorine compound, wherein the compounds are separate compounds or comprise a unitary composition; wherein R1, R2 and R3 independently represent a hydrogen atom; halogen atom; hydroxy group; amino group; alkylamino group, alkyl group, hydroxyalkyl group, acyl group, haloalkyl group or alkoxy group having 1 to 4 carbon atoms; or an acylamido group having 1 to 10 carbon atoms; and A represents 2-thiazolamine; 2-propenenitrile; 2-propenoic acid; alkyl ester or hydroxyalkyl ester of 2-propenoic acid having 1 to 4 carbon atoms; or —CHCHCONR5R6 group, where R5 and R6 represent independently hydrogen atom, alkyl or hydroxyalkyl having 1 to 4 carbon atoms; and wherein the stabilised chlorine compound comprises the reaction product of a reaction between active chlorine and a nitrogenous reactant selected from ammonium, urea, carbamate and dimethylhydantoin.
