Quaternary ammonium compounds (QUATS) are primarily used for their effectiveness in reducing microbial load rather than eliminating all pathogens or providing complete sterilization. They work by disrupting the microbial cell membrane, which leads to the inactivation of many bacteria and some viruses, thus decreasing the overall number of microorganisms present.

In non-critical areas, such as those where items may come into contact with intact skin but not directly into sterile body areas, the goal is typically to maintain hygiene and reduce the potential transmission of infections. This focus aligns with the use of QUATS, as they are practical for daily cleaning and disinfection routines where achieving complete sterilization is unnecessary.

Complete surgical sterilization is reserved for critical areas where instruments come in direct contact with sterile tissues. Meanwhile, prions, which are misfolded proteins implicated in certain neurodegenerative diseases, require far harsher conditions for destruction than what QUATS can provide, thus underscoring the specific applicability of QUATS in reducing microbial load in appropriate settings.
