    Study Notes

    Chemical Disinfectants

    • Types of Chemical Disinfectants:
      • Quaternary Ammonium Compounds (Cationic detergents): Kill all microorganisms, including spores
      • Alcohols: Effective against bacteria, fungi, and some viruses

    Alcohols

    • Effectiveness: Destroy bacteria, fungi, and some viruses
    • Common Use: Small surfaces and hand sanitizers
    • Examples: Ethanol and isopropanol are common alcohol-based disinfectants
    • Key Fact: Alcohols are used in settings that require infection control

    Chemical Disinfectants

    • Chemical disinfectants are important for infection control.
    • Chemical disinfectants kill harmful microorganisms on surfaces and equipment.
