Applications
Medical & Disinfection Industry (Core Application)
Core active ingredient for medical skin disinfectants, wound cleansers, surgical instrument disinfectants and surface sanitizers. It provides broad-spectrum sterilization against Gram-positive and Gram-negative bacteria, fungi and enveloped viruses, with low irritation to skin and mucous membranes, widely used in hospitals, clinics and public health disinfection.
Daily Chemical & Cosmetics
Widely used as preservative and antibacterial agent in hand sanitizers, wet wipes, shampoos, skin care products and oral care products. It inhibits microbial growth, extends product shelf life, and meets global cosmetic and pharmaceutical safety regulations.
Water Treatment Industry
High-efficiency bactericidal algaecide for swimming pools, industrial circulating water, cooling towers, oilfield water injection and wastewater systems. It effectively kills bacteria, fungi and algae, inhibits biofilm formation, with long duration and good compatibility with water treatment chemicals.
Agriculture & Animal Husbandry
Used as farm environmental disinfectant, livestock drinking water disinfectant and aquaculture water purifier. It controls pathogenic microorganisms, reduces disease transmission and improves breeding environment safety.
Textile & Paper Industry
Applied as antibacterial finishing agent for textiles, non-woven fabrics, medical dressings and paper products. It endows materials with long-lasting antibacterial, anti-mildew and deodorant properties, suitable for medical textiles and food packaging papers.
Other Industrial Applications
Used as bactericidal preservative for wood, leather and coating products. Also applied in oilfield drilling, metalworking fluids and industrial circulating systems to control microbial contamination.
