Microbicidal composition
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 4,4-dimethyloxazolidine. The weight ratio of the nonionic surfactant to 4,4-dimethyloxazolidine is from 1:0.0286 to 1:0.1143 or 1:0.32 to 1:0.9143.
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;
and (b) 4,4-dimethyloxazolidine; wherein a weight ratio of said nonionic surfactant to 4,4-dimethyloxazolidine is from 1:0.0286 to 1:0.1143 or 1:0.32 to 1:0.9143; and wherein R 1 is 2-ethylhexyl.
2. A synergistic microbicidal composition comprising: (a) 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; and (b) 4,4-dimethyloxazolidine; wherein a weight ratio of said nonionic surfactant to 4,4-dimethyloxazolidine is from 1:0.06 to 1:0.6857;
and wherein said mixture of C 8 -C 14 linear alkyl groups comprises from 60 to 75 wt % C 8 -C 10 linear alkyl groups and 25 to 40 wt % C 12 -C 14 linear alkyl groups.
