WebHow does benzalkonium chloride kill bacteria? Benzalkonium chloride (BAC) is a wide spectrum quaternary ammonium antibacterial agent that has been used in various dental composites. It is cationically charged and induces antibacterial action through attraction to the negatively charged bacterial membrane. The antimicrobial activity is dependent on the chain length. For example, yeast and fungi are most affected by C12, gram positive by C14, and gram negative by C16. The greatest biocidal activity is associated with the C12 dodecyl and C14 myristyl alkyl derivatives. The mechanism of bactericidal/microbicidal action is thought to be due to disruption of intermolecular interactions. This can cause dissociation of cellular membrane lipid bilayers, whic…
