MASON® CS-125
68391-01-5 (Alt. 53516-76-0)MASON® CS-125 is a cationic surfactant based on alkyldimethylbenzylammonium chloride (benzalkonium), formulated as a clear liquid solution ranging from colorless to straw-colored. It belongs to the quaternary ammonium compound family and is characterized by its high efficacy as a biocidal agent in industrial systems.
It stands out for its broad-spectrum activity against sulfate-reducing bacteria, acid-producing bacteria, algae, and biofilm formation, acting through disruption of microbial cell membranes. Its cationic nature enables strong adsorption onto surfaces, providing efficient and long-lasting microbiological control.
