C11E13: Chemical Control Part 1

Chapter 11, Episode 13Chemical control methods work by targeting key cellular structures such as the cell wall, membrane, proteins, or nucleic acids, resulting in either microbial death or growth inhibition. The effectiveness of a chemical agent depends on factors like concentration, contact time, and presence of organic material. Common agents introduced include halogens, phenolic compounds, and chlorhexidine, which primarily disrupt membranes and proteins. These agents are widely used in healthcare and everyday settings, with selection based on effectiveness, safety, and the level of microbial control required.
