A new publication from Beatriz Pereira and Dr. Ilias Tagkopoulos reviewing benzalkonium chlorides (BACs). The review overviewed the current market and regulations of BACs as well as available safety data and the correlation between BACs and increasing of microbial tolerance to chemicals. The work suggested a role of BACs in generating selective environments that favor microbial cross-resistance to multiple compounds.
