Microbicidal composition
A synergistic microbicidal composition having two components. The first component is a nonionic surfactant with structure: R 2 O(CH 2 CH(CH 3 )O) 3 (CH 2 CH 2 O) 5 H, where R 2 is a mixture of C 8 -C 14 linear alkyl groups. The second component is 2-bromo-2-nitropropane-1,3-diol. The weight ratio of the nonionic surfactant to 2-bromo-2-nitropropane-1,3-diol is from 1:0.08 to 1:0.12 or 1:0.2 to 1:1.8286.
1. A synergistic microbicidal composition comprising: (a) 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; and (b) a mixture of 4-(2-nitrobutyl)morpholine and 4,4′-(2-ethyl-2-nitrotrimethylene)dimorpholine in a weight ratio of 81:5; wherein a weight ratio of said nonionic surfactant to said mixture is from 1:0.0006 to 1:0.2743.
2. The synergistic microbicidal composition of claim 1 in which R 1 is 2-ethylhexyl.
