Quaternary ammonium compounds, often referred to as quats, are widely used as disinfectants in barber shops due to their effectiveness against a broad range of pathogens, including bacteria, viruses, and fungi. These compounds are favored in a barbering environment because they do not damage tools and equipment, are relatively safe for use on surfaces, and have a low level of toxicity compared to some other disinfectant options. Quats can also provide a residual effect, meaning they can continue to kill germs even after the initial application, enhancing the sanitation of the workspace.

In addition to their disinfecting properties, quats are often preferred for their ease of use; they can be diluted in water to create a solution that is both effective and economical. This versatility makes them a common choice for maintaining hygiene in barber shops, ensuring tools, surfaces, and equipment are adequately sanitized between uses to protect both clients and barbers.
