Microbicidal composition

Abstract

A synergistic microbicidal composition having two components. The first component is a nonionic surfactant with structure: R 1 O(CH 2 CH(CH 3 )O) 5 (CH 2 CH 2 O) 9 H, where R 1 is a C 8 alkyl group. The second component is cis-1-(3-chloroallyl)-3,5,7-triaza-1-azoniaadamantane chloride. The weight ratio of the nonionic surfactant to cis-1-(3-chloroallyl)-3,5,7-triaza-1-azoniaadamantane chloride is from 1:0.2 to 1:1.1429.
