Microbicidal composition
A synergistic microbicidal composition comprising a non-ionic surfactant and glutaraldehyde and a method for inhibiting the growth of microorganisms in an aqueous medium.
1. 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; and (b) glutaraldehyde; wherein a weight ratio of the glutaraldehyde to nonionic surfactant is from 17:1 to 1:4.
2. A method for controlling the growth of microorganisms in an aqueous medium; the method comprising adding to the aqueous medium the synergistic microbicidal composition of claim 1 .
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) 5 H
where R 2 is a mixture of C 8 -C 14 linear alkyl groups; and (b) glutaraldehyde; wherein a weight ratio of glutaraldehyde to nonionic surfactant is from 17:1 to 3:1.
4. A method for controlling the growth of microorganisms in an aqueous medium; the method comprising adding to the aqueous medium the synergistic microbicidal composition of claim 3 .
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) 13 H
where R 2 is a mixture of C 8 -C 14 linear alkyl groups; and (b) glutaraldehyde; wherein a weight ratio of glutaraldehyde to nonionic surfactant is from 8:1 to 1:1.
6. A method for controlling the growth of microorganisms in an aqueous medium; the method comprising adding to the aqueous medium the synergistic microbicidal composition of claim 5 .
