MAQUAT® 4450-CTM is a formulation based on quaternary ammonium compounds, primarily didecyldimethylammonium chloride (DDAC), designed for industrial microbiological control applications in aqueous systems. It is characterized by its high efficacy as a broad-spectrum biocide, acting against algae, slime-forming bacteria, and sulfate-reducing bacteria, helping to prevent biofouling and microbiological contamination.
