Novel bis-quaternary ammonium salt compound having bactericidal activity

摘要

Formula (1) [In formula, R1 and R2 show a C6-C18 alkyl group each independently. R3 and R4 each independently represent a hydroxymethyl group or an alkyloxycarbonyl group. n1 and n2 each independently represent an integer of 1 to 3. X1- and X2- each independently represents an anion residue. And a bis-quaternary ammonium salt compound represented by formula (2): wherein R 1 and R 2 each independently represents an alkyl group having 6 to 18 carbon atoms. R5 and R6 each independently represent a hydroxymethyl group or an alkyloxycarbonyl group, at least one of which is a hydroxymethyl group. n1 and n2 each independently represent an integer of 1 to 3. X1- and X2- each independently represents an anion residue. A substance in which a bisquaternary ammonium salt compound represented by formula (1) is supported or immobilized, and a bisquaternary ammonium salt compound represented by formula (1) and a bisquaternary ammonium salt compound represented by formula (2) A bactericidal composition containing at least one substance selected from the group consisting of substances that carry or are immobilized.
