Abstract
Official abstract text for this publication.
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 2-decylthioethylamine. The weight ratio of the nonionic surfactant to 2-decylthioethylamine is from 1:0.004 to 1:0.0137 or 1:0.016 to 1:0.4571.
First claim

The invention claimed is: 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 2-ethylhexyl; and (b) 2-decylthioethylamine; wherein a weight ratio of said nonionic surfactant to 2-decylthioethylamine is from 1:0.004 to 1:0.0137 or 1:0.016 to 1:0.4571. 2. A method for inhibiting the growth of microorganisms in an aqueous medium; said method comprising adding to said aqueous medium: (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 2-ethylhexyl; and (b) 2-decylthioethylamine; wherein a weight ratio of said nonionic surfactant to 2-decylthioethylamine is from 1:0.004 to 1:0.0137 or 1:0.016 to 1:0.4571. 3. 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) 7 H where R 2 is a mixture of C 8 -C 14 linear alkyl groups which 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; and (b) 2-decylthioethylamine; wherein a weight ratio of said nonionic surfactant to 2-decylthioethylamine is from 1:0.0023 to 1:0.4571. 4. A method for inhibiting the growth of microorganisms in an aqueous medium; said method comprising adding to said aqueous medium: (a) a nonionic surfactant with structure: R 2 O(CH 2 CH(CH 3 )O) 3 (CH 2 CH 2 O) 7 H where R 2 is a mixture of C 8 -C 14 linear alkyl groups which 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; and (b) 2-decylthioethylamine; wherein a weight ratio of said nonionic surfactant to 2-decylthioethylamine is from 1:0.0023 to 1:0.4571. 5. 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 which 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; and (b) 2-decylthioethylamine; wherein a weight ratio of said nonionic surfactant to 2-decylthioethylamine is from 1:0.0023 to 1:0.3657.
