Two types of disinfectants used in a salon or spa are hospital and tuberculocidal.

• A. Alcohol-based and phenolic
• B. Chlorine-based and iodophor
• C. Quats and detergents
• D. Hospital and tuberculocidal

Answer: (D)

In salon practice, you think about disinfection levels in terms of how broadly and how rigorously the product has been tested. Hospital-grade disinfectants are registered for use in healthcare-like settings and provide broad-spectrum activity against many pathogens. Tuberculocidal disinfectants are specifically tested to kill Mycobacterium tuberculosis, indicating a higher level of disinfection. Many products can be labeled as both hospital-grade and tuberculocidal, but the key idea is that these two categories reflect the standard levels you’d rely on for surfaces and tools that may contact blood or bodily fluids and for tougher organisms like the tubercle bacillus. That is why the correct choice identifies hospital-grade and tuberculocidal as the two types used in a salon or spa setting. The other options describe particular chemical families or generic disinfectants, which don’t capture the specific category labels required in practice.
