How Quaternary Ammonium Compounds Work?

Quaternary ammonium compounds work by denaturing the proteins of the bacterial or fungal cell, affecting the metabolic reactions of the cell and causing vital substances to leak out of the cell, causing death.

How does quaternary ammonium kill bacteria?

Quats are cationic (positively charged) ions which bind to the negatively charged outer membranes of germs; breaking down the membrane resulting in the killing or inactivation of those germs.

What is the mechanism of action of Quats as a disinfectant?

Mode of Action: The bactericidal action of the quaternaries has been attributed to the inactivation of energy-producing enzymes, denaturation of essential cell proteins, and disruption of the cell membrane.
