Which disinfectant has the most potent viricidal properties?

The most potent viricidal properties are found in glutaraldehyde, which is a high-level disinfectant commonly used in healthcare settings for sterilizing instruments and equipment. Glutaraldehyde works effectively against a wide range of viruses, bacteria, and fungi. Its mechanism involves alkylation, which disrupts the cellular proteins and nucleic acids of microorganisms, leading to their inactivation.

Glutaraldehyde's efficacy is particularly noted in its ability to destroy even more resilient viruses, making it suitable for environments requiring strict infection control measures. Its use, however, is associated with certain safety concerns, such as the potential for toxicity and irritation, necessitating proper ventilation and personal protective equipment during application.

While sodium hypochlorite, chlorhexidine, and alcohol at 70% concentration are also effective disinfectants, they do not match the viricidal capabilities of glutaraldehyde in terms of breadth and potency. Sodium hypochlorite is effective against viruses but is more commonly recognized for its bactericidal properties. Chlorhexidine, on the other hand, is primarily bactericidal and has limited viricidal action. Alcohol, particularly at 70%, is effective against many viruses but is less reliable against certain types of non
