Triclosan exerts broad-spectrum antibacterial effects by inhibiting enoyl-acyl carrier protein reductase (ENR), a key enzyme in bacterial fatty acid synthesis, disrupting cell membrane integrity and bacterial growth. Benzalkonium chloride is a cationic surfactant that damages microbial cytoplasmic membranes, causing leakage of cell contents and rapid bacterial death. Light liquid paraffin serves as an emollient, softening and moisturizing the skin, thereby maintaining the skin barrier and reducing irritation, which supports the antiseptic effects.
