State rules require the use of ________ disinfecting solutions.

State rules require the use of ________ disinfecting solutions.

• A. Gas
• B. Foam
• C. Liquid
• D. Solid

Answer: (C)

Disinfectants in state rules are used as liquids because they need to wet surfaces and stay in contact long enough to kill microbes. Liquid solutions can be prepared to the proper concentration, applied evenly by wiping or soaking, and cling to irregular surfaces and tools to ensure thorough disinfection. Gas forms require specialized equipment and containment and aren’t practical for routine salon disinfection, while solids don’t provide reliable wet contact or easy preparation. Foam isn’t the standard format addressed by regulations, so the mandated form is liquid disinfecting solutions.
