What is the active ingredient in bleach that is commonly used as a disinfectant in salons?

5.25% sodium hypochlorite
Hydrogen peroxide
Ammonium hydroxide
Isopropyl alcohol

The correct answer is: 5.25% sodium hypochlorite

The active ingredient in bleach that is widely used as a disinfectant in salons is sodium hypochlorite, specifically in a concentration of 5.25%. Sodium hypochlorite is effective at killing bacteria, viruses, and fungi on surfaces, which is essential in maintaining a hygienic environment in any salon setting. This concentration is often used because it provides an effective level of disinfection while being safe for various salon materials when properly diluted. Other options like hydrogen peroxide, ammonium hydroxide, and isopropyl alcohol are also disinfectants but serve different purposes and may not provide the same broad-spectrum antimicrobial action as sodium hypochlorite in the context of salon disinfection. Understanding the specific uses and effectiveness of these various disinfectants is crucial for estheticians to comply with health and safety regulations.
