Benzalkonium chloride is a cationic surfactant classified as a non-oxidizing bactericide. It exhibits broad-spectrum and high-efficiency bactericidal and algaecidal capabilities, effectively inhibiting the reproduction of bacteria, algae, and the growth of slime in water systems. Additionally, it possesses excellent slime stripping properties, moderate dispersion and penetration effects, as well as certain oil-removing, deodorizing, and corrosion-inhibiting functionalities. Benefiting from its superior antimicrobial performance, benzalkonium chloride is widely applied in the medical and healthcare sector.

1. Skin Disinfection – Basic Clinical Disinfection Scenarios

• Preoperative skin preparation

• Disinfection of injection sites

• Daily skin cleansing around wounds

2. Mucosal Disinfection & Cavity Irrigation – Infection Prevention/Adjuvant Therapy

• Disinfection of mucosal surfaces (e.g., oral cavity, urethra, nasal cavity)

• Adjuvant treatment for inflammation in mucosal areas

3. Medical Device Disinfection (Non-invasive/Semi-invasive Devices)

• Disinfection of thermometers, blood pressure cuff sleeves, ultrasound probes, endoscopes (non-sterile type), dental instruments, etc.

4. Environment & Object Surface Disinfection (Hospital Infection Control)

• Disinfection of high-touch surfaces in hospitals, such as ward floors, walls, hospital beds, treatment tables, and door handles

5. Special Medical Scenario Applications

• Wound care

• Ocular disinfection

• Antimicrobial treatment of medical dressings

◆  Warm Reminder from Shandong Fengquan:

Benzalkonium chloride should be stored in a cool, dry place, protected from fire, direct sunlight, and rain.
