What is the minimum concentration of a quaternary ammonium compound needed for immersion?

The correct minimum concentration of a quaternary ammonium compound needed for immersion is 1,000 parts per million (ppm). This concentration is crucial for ensuring the effectiveness of the disinfectant in killing bacteria and other pathogens on surfaces. Quaternary ammonium compounds are widely used in the cosmetology industry for their antimicrobial properties, particularly in maintaining hygiene within salons and spas.

A concentration of 1,000 ppm has been established as effective for achieving adequate disinfection without posing risks of overexposure or damage to tools and equipment. Lower concentrations may not effectively eliminate harmful microorganisms, while higher concentrations could be unnecessary and potentially harmful to both the products being disinfected and the individuals using them. Understanding this standard helps practitioners make informed decisions regarding sanitation practices in compliance with Oregon state laws.
