Name two common EPA-registered disinfectants used in salons and their active ingredients.

• A. Hydrogen peroxide-based products and alcohol-based products.
• B. Chlorine bleach and quats such as benzalkonium chloride.
• C. Sodium chloride and acetic acid.
• D. Sodium hypochlorite and quaternary ammonium compounds.

Answer: (B)

Two common EPA-registered disinfectants you’ll see in salons are chlorine bleach products and quats (quaternary ammonium compounds). Chlorine bleach relies on sodium hypochlorite as the active ingredient, and when used at proper dilutions and with the recommended contact time, it provides broad-spectrum disinfection for nonporous surfaces and tools. Quats, with benzalkonium chloride as a representative active ingredient, are another widely used option that effectively disinfects many bacteria and viruses on similar surfaces and implements. These two categories are favored in salons because they’re widely available, have clear EPA labeling with usage instructions, and cover a broad range of pathogens. While other disinfectants like hydrogen peroxide or alcohol exist, the combination of chlorine bleach (sodium hypochlorite) and quats (benzalkonium chloride) is the most commonly encountered duo in salon sanitation. Always follow the product label for dilution, contact time, and safety.
