Biocides for Agrochemicals

Benzalkonium chloride: Product description At Quimiconsult we offer Benzalkonium Chloride 80 %, an industrial disinfectant and biocidal agent belonging to the quaternary ammonium salt family, widely used in professional sanitization and microbiological control processes. It comes as a colorless to slightly yellow liquid with a minimum active content of 80 %, designed for concentrated formulations that require high efficacy, chemical stability and easy dosing. Benzalkonium chloride is a non-volatile biocide, effective against a broad range of bacteria, fungi, algae and enveloped viruses. It acts mainly by interacting with the cell membranes of microorganisms, which inactivates them. For this reason, it is used as an active ingredient in industrial, institutional and livestock disinfectants, as well as in sanitizing solutions for surfaces, equipment and process areas. For those asking what benzalkonium chloride is used for, or looking for a reliable benzalkonium chloride disinfectant, o…
