Product Application of Bropol
Bropol delivers potent inhibitory effects against a wide array of phytopathogenic bacteria and is primarily deployed as a seed treatment agent.
Thanks to its broad‑spectrum antibacterial traits, it has served as a disinfectant within the pharmaceutical sector since the 1960s. As the cosmetics industry expanded rapidly, its favorable water solubility and robust antimicrobial potency also facilitated its extensive adoption as a preservative in cosmetic products.
In recent years, Bropol has found rising utilization in feed additives, coating systems, fur preservation, circulating water disinfection for air conditioning units, sterilization of oilfield injection water, as well as sanitation treatment for aircraft, vehicles and vessels, driving sustained growth in market demand.
