User Asked Question:
Q: What are the differences between benzalkonium chloride (BAC) and alcohol-based disinfectants?
A: Mechanism of Action: BAC is a cationic surfactant that works by disrupting the microbial cell membrane, while alcohol kills microorganisms by denaturing proteins.
Duration of Effect: BAC provides longer-lasting antimicrobial effects, whereas alcohol acts quickly but offers no residual protection.
Impact on Skin: BAC is generally less irritating to the skin compared to high-concentration alcohol solutions.
