Chemical Agents for Microbial Control

Alcohols are widely used as antiseptics and disinfectants due to their ability to disrupt lipid membranes.

Phenols and their derivatives denature proteins, disrupt cell membranes, and remain effective longer in organic matter, making them potent disinfectants.

Hydrogen peroxide, a strong oxidizer, is a topical antiseptic for wound care.

Similarly, halogen-releasing antiseptics like povidone-iodine oxidize and damage macromolecules, including DNA and membranes.

Chlorine-based agents like chloramines and sodium hypochlorite disinfect medical instruments, water, and surfaces, while chlorine dioxide gas decontaminates large buildings.

Aldehydes, such as glutaraldehyde, act as crosslinking agents that inactivate microbial proteins, making them effective medical sterilants.

Ethylene oxide gas, a potent alkylating agent, sterilizes temperature-sensitive materials like plastics.

Quaternary ammonium compounds, found in some Lysol formulations, disrupt plasma membranes and are used in the food industry to sanitize utensils and surfaces.

Pine oils are natural detergents that serve as effective general-purpose household disinfectants.
