Chemical disinfectants play a crucial role in preventing the spread of infectious diseases by eliminating harmful microorganisms on surfaces. Here are some key points about the prevention of infections by chemical products:

• Types of Chemical Disinfectants: Ethyl alcohol and isopropyl alcohol are two commonly used chemical disinfectants. They are water-soluble compounds with germicidal characteristics.

• Mode of Action: The antimicrobial action of alcohol is primarily due to the denaturation of proteins. This mechanism is supported by the observation that proteins are denatured more quickly in the presence of water.

• Microbicidal Activity: Ethyl alcohol, at concentrations of 60%–80%, is a potent virucidal agent inactivating all of the lipophilic viruses and many hydrophilic viruses.

• Use of Disinfectants: Chemical disinfectants can be used for prevention as well as intervention. They are the ideal first line of defense against bacteria and viruses.

• Safety Measures: While chemical disinfectants are effective, they can also pose health risks if not used properly. Therefore, it’s important to follow manufacturer’s instructions and safety guidelines when using these products
