Cleaning and sterilization are critical Prerequisite Programs in sanitation management based on HACCP. Most food factories clean and sanitize equipment daily after production using detergents containing benzalkonium chloride (BAC). However, in factories that produce oil and fat-rich foods, it has been discovered that microbes can persist on production equipment.

Quaternary ammonium compounds (QACs) play crucial disinfectant roles in healthcare, industry, and domestic settings. Most commercially utilized QACs like benzalkonium chloride have a common architectural theme, leading to a rise in bacterial resistance and urgent need for novel structural classes. Some potent QACs such as chlorhexidine (CHX) and octenidine (OCT) feature a bolaamphiphilic architecture, comprised of two cationic centers at the molecular periphery and a non-polar region connecting them; these compounds show promise to elude bacterial resistance mechanisms.

Antiseptics have been used for infection control against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Ethanol (EtOH) was found to be effective against SARS-CoV-2, while chlorhexidine gluconate (CHG) was less effective. Therefore, virucidal activity may differ between different classes of antiseptic agents.

Pitting corrosion caused by sulfate-reducing bacteria (SRB) significantly shortens the lifespan of metallic pipelines. Antibacterial coatings containing S-responsive drug-loaded nanocontainers represent a promising method to mitigate SRB corrosion. However, the challenge of balancing rapid bactericide release with continuous antibacterial effect limits their practical application.

A representative surfactant, benzalkonium chloride (BAC) is used as a disinfectant, but sometimes causes serious side effects, including lung disorders such as interstitial pneumonia. However, its pathogenic mechanisms remain unexplained. In this study, we identified a novel mechanism by which BAC initiates inflammatory responses that may be responsible for its side effects.
