- AHydrogen peroxide (3%)
- BIsopropyl alcohol (70%)
- CHousehold bleach solution
- DQuaternary Ammonium Compounds (Quats)
Show answer & explanationAnswer & explanation
Correct answer: D. Quaternary Ammonium Compounds (Quats)
Quaternary Ammonium Compounds (Quats) are widely used and approved for general salon disinfection of hard, non-porous surfaces. They are effective against a broad spectrum of pathogens and are safer than some other options for routine use.
Why the other options are wrong
- A. Hydrogen peroxide in 3% concentration is a weak disinfectant and not suitable for general salon disinfection of implements or surfaces.
- B. Isopropyl alcohol is generally not considered a broad-spectrum disinfectant for salon surfaces and has a rapid evaporation rate, limiting contact time.
- C. Household bleach is corrosive and can damage salon surfaces and equipment over time, and its efficacy is highly dependent on proper dilution.
