A technician is preparing to disinfect non-porous implements after a service. Which type of disinfectant is generally considered most effective for killing a broad spectrum of pathogens, including bacteria, viruses, and fungi, in a salon setting?
- AQuaternary Ammonium Compounds (Quats)
- BHousehold bleach (sodium hypochlorite)
- CPhenolics
- DAlcohol (70% isopropyl)
Show answer & explanationAnswer & explanation
Correct answer: A. Quaternary Ammonium Compounds (Quats)
Quaternary Ammonium Compounds (Quats) are widely used and approved salon disinfectants. They are effective, relatively safe, and designed to kill a broad spectrum of bacteria, viruses, and fungi on non-porous surfaces when used according to manufacturer's instructions.
Why the other options are wrong
- B. Bleach is a strong disinfectant but can be corrosive to implements, irritating to skin/respiratory system, and requires specific dilutions for efficacy and safety.
- C. Phenolics are strong disinfectants but can be skin irritants, toxic, and are often reserved for specific applications due to their potential hazards.
- D. Alcohol is a good antiseptic but less effective as a broad-spectrum disinfectant for salon implements, especially against some viruses and spores.
Salon Disinfectants
Chemical solutions used to destroy most bacteria, fungi, and viruses on non-porous surfaces and implements in a salon.
- Must be EPA-registered.

- Quats are a common and effective choice.
Memory trick: Quats are Quality Killers.
