Antiseptic and disinfectant

Affect permeability of the microbe cell membrane

Should only be used as disinfectant

Effective against gram -positive and negative bacteria, fungi, and viruses

Can be used as both disinfectants and antiseptics

Halogens used as antiseptics

Halogens used as disinfectants

Dissolve lipids in the cell wall and membrane

Affect the protein structure of microbes

Destroys DNA and microbial proteins

Dissolve membrane lipids and coagulate microbial proteins

Interfere with proteins and enzymes of the microbes

Denature microbial proteins

Works best against anaerobic bacteria, can be used as either a disinfectant or an antiseptic

Halogens as Disinfectants and Antiseptics

Halogens are effective against a wide range of microorganisms, including gram-positive and negative bacteria, fungi, and viruses.
They can be used as both disinfectants and antiseptics, depending on the context.

Mechanism of Action

Halogens affect the permeability of the microbe cell membrane.
They dissolve lipids in the cell wall and membrane, disrupting the structural integrity of the microbe.
Halogens also denature microbial proteins, interfering with their function and ultimately leading to the destruction of the microbe.
Additionally, they can destroy DNA and microbial proteins, further contributing to their antimicrobial effects.

Uses of Halogens

Halogens can be used as disinfectants, effective against a broad range of microorganisms.
They can also be used as antiseptics, with some halogens being more effective in this context than others.
Specifically, halogens work well against anaerobic bacteria, and can be used as either a disinfectant or an antiseptic in these cases.
