Product Application
Bropol exhibits potent activity against a wide spectrum of phytopathogenic bacteria and is primarily employed for seed dressing.
Thanks to its broad‑spectrum bactericidal performance, it has served as a disinfectant within the pharmaceutical sector dating back to the 1960s. As the cosmetics industry expanded swiftly, its favorable water solubility and robust antimicrobial capacity also made it a popular preservative for cosmetic formulations.
Over recent years, Bropol has found rising adoption across many fields: animal feed, coatings, fur conservation, circulating water sterilization for air‑conditioning systems, biocidal treatment for oilfield injected water, as well as sanitization for aircraft, vehicles and vessels, which drives steady expansion of its market demand.
