Antimicrobial Test USP Method

Disinfectants are chemical agents used on inanimate surfaces and objects to destroy infectious fungi, viruses, and bacteria, but not necessarily their spores. Sporicidal and antiviral agents may be considered a special class of disinfectants. Disinfectants are often categorised as high-level, intermediate-level, and low-level based upon their efficacy against various microorganisms.

The effectiveness of a disinfectant depends on its intrinsic biocidal activity, the concentration of the disinfectant, the contact time, the nature of the surface disinfected, the hardness of the water used to dilute the disinfectant, the number of organic materials present on the surface, and the type and the number of microorganisms present.
