Abstract
Official abstract text for this publication.
A biocidal composition comprising a synergistic ratio of 2,2-dibromomalonamide and hydroxymethyl-substituted phosphorus compound, and its use for the control of microorganisms in aqueous and water-containing systems.
First claim
Opening claim text (preview).
What is claimed is: 1. A biocidal composition comprising a synergistic blend of 2,2-dibromomalonamide and tetrakis(hydroxymethyl)phosphonium sulfate wherein the weight ratio of 2,2-dibromomalonamide to the tetrakis(hydroxymethyl)phosphonium sulfate is between 1:4 and 1:16 and further wherein the synergistic blend is synergistically effective against anaerobic bacteria. 2. The biocidal composition according to claim 1 which is: paint, coating, aqueous emulsion, latex, adhesive, ink, pigment dispersion, household or industrial cleaner, detergent, dish detergent, mineral slurry polymer emulsion, caulk, adhesive, tape joint compound, disinfectant, sanitizer, metalworking fluid, construction product, personal care product, textile fluid, spin finish, industrial process water, oil and gas field injection/fracturing, flowback and produced water and fluids as well as functional fluids, fuel, air washer, wastewater, ballast water, filtration systems, swimming pool or spa water. 3. A method for controlling microorganism growth and metabolic activities in an aqueous or water-containing system, the method comprising treating the aqueous or water-containing system with an effective amount of a composition according to claim 1 . 4. The method according to claim 3 wherein the aqueous or water-containing system is paint, coating, aqueous emulsion, latex, adhesive, ink, pigment dispersion, household or industrial cleaner, detergent, dish detergent, mineral slurry polymer emulsion, caulk, adhesive, tape joint compound, disinfectant, sanitizer, metalworking fluid, construction product, personal care product, textile fluid, spin finish, industrial process water, oil and gas field injection/fracturing, flowback and produced water and fluids as well as functional fluids, fuel, air washer, wastewater, ballast water, filtration system, swimming pool or spa water.
