What is the name of the chemical which kills most pathogenic organisms, but does not kill spores?

The term that refers to a chemical capable of killing most pathogenic organisms, while not being effective against spores, is a disinfectant. Disinfectants are used to reduce microbial count on inanimate surfaces and can significantly decrease the presence of dangerous pathogens, making them valuable for maintaining hygiene in various environments, especially in healthcare settings. However, they do not achieve the complete destruction of all microbial life, particularly bacterial spores, which are more resistant and require a different level of treatment, such as sterilization.

Antiseptics, while effective at reducing microbial load, are typically used on living tissue to prevent infection. Sterilants are potent chemicals that destroy all forms of microbial life, including spores. Cleansers are generally used for cleaning purposes and do not have specific antimicrobial effects. Thus, a disinfectant specifically fits the definition as it effectively addresses pathogenic organisms without achieving the higher standard of sterilization required to eliminate spores.
