Two types of disinfectants used in a salon or spa are:

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

Answer: (D)

Disinfection in a salon hinges on using products that are proven to kill a broad range of pathogens on non-porous surfaces and implements. Hospital-grade disinfectants are EPA-registered products designed to provide broad-spectrum kill on these surfaces, suitable for everyday use in spas and salons. Tuberculocidal disinfectants represent a higher level of disinfection because they are capable of killing Mycobacterium tuberculosis, a tougher organism to eradicate. Using a hospital-grade disinfectant that is tuberculocidal ensures both wide coverage and a strong disinfecting standard, which is why this pairing is what you’d rely on in practice. Other options either describe chemical families or cleaning agents that don’t consistently meet the required disinfection level (for example, some are only sanitizers or detergents and don’t provide tuberculocidal efficacy), so they don’t fit the standard practice as well.
