Benzalkonium Chloride, better known as BZK, is a quaternary ammonium. It is used for antiseptic and disinfectant. The chemical usage is similar to that of a Clorox Wipe to kill germs. In simpler terms, BZK is a chemical compound used to kill bacteria and germs. Quaternary ammonium compounds, also known as Quats, are found in all types of disinfectants. BZK is also classified as a cationic surfactant. The word surfactant means a surface-active agent. Surfactants are molecules that stir up activity on the surface you are cleaning to help trap bacteria and remove it from the surface.



It is time for a biology lesson- Hydrophilic vs. Hydrophobic. Hydrophilic means water-loving whereas hydrophobic means water-hating. The surfactants have hydrophilic heads and hydrophobic tails. The hydrophilic heads pull the surrounding soils off the surface and into the cleaning solution. This is how BZK works to get rid of bacteria and viruses. With BZK’s antimicrobial properties, the molecules trap the germs, allowing the chemical compounds (the quats) to penetrate and kill the germs.

How BZK Diminishes Viruses

BZK has historically helped battle E.coli, influenza, and other bacteria that cause illnesses like pneumonia. A new study from researchers at Brigham Young University found that BZK is just as effective as alcohol when it comes to breaking down germs. The study also showed that the BZK substance wiped out 99.9% of the novel coronavirus within 15 seconds of the experiment. The fight against germs also lasts longer, up to 120 seconds of sanitization. 

BZK Sanitizers and Wipes

According to both doctors and scientists, BZK is highly effective in both sanitizers and wipes. Dr. Sidney Bondurant, the chief medical officer for Three Kings, reported that BZK is more gentile on the hands than alcohol. BZK is also FDA approved, making it safe sanitation for your skin and home. You can purchase alcohol free, BZK products here by Tazza.
