Glutaraldehyde based biocidal compositions and methods of use
View Patent ↗Provided are biocidal compositions comprising glutaraldehyde and a compound selected from the group consisting of 1-(3-chloroallyl)-3,5,7-triaza-1-azoniaadamantane; tris(hydroxymethyl)-nitromethane; and a hexahydrotriazine compound. The compositions are useful for controlling microorganisms in aqueous or water-containing systems.
1. A synergistic combination effective for killing anaerobic bacteria comprising:
glutaraldehyde; and
tris(hydroxymethyl)-nitromethane
wherein the synergistic glutaraldehyde to tris(hydroxymethyl)-nitriomethane weight ratio is between 9:1 and 1:3.
2. A composition according to claim 1 further comprising one or more surfactantants, ionic/nonionic polymers, scale and corrosion inhibitors, oxygen scavengers or additional or additional biocides.
3. A method for controlling microorganisms in an aqueous or water-containing system, the method comprising treating the system with an effective amount of a composition according to claim 1 .
