Question 1

Which disinfectant concentration of isopropyl alcohol is considered effective for sanitizing salon implements?

Accepted Answer

70%

Answer

70% isopropyl alcohol is the most effective concentration because it allows slower evaporation, giving it more time to kill pathogens.

Question 2

Stylists must decline services on clients with open sores or infectious conditions and refer them to a medical professional.

Question 3

What does the term 'bacteriostatic' mean in the context of salon disinfectants?

Accepted Answer

Answer

Most EPA-registered disinfectants require a 10-minute contact time to effectively disinfect metal salon tools.
