What is the active ingredient in chemical vapor sterilization?

In chemical vapor sterilization, the active antimicrobial is formaldehyde in the form of vapor. This method generates formaldehyde gas inside a sealed chamber, where the gas penetrates instruments and achieves sterilization at a relatively low temperature. The other substances listed play roles in different sterilization or disinfection processes, not the active gas in this method: glutaraldehyde is typically used as a liquid immersion sterilant, ethanol is mainly a surface disinfectant, and hydrogen peroxide is used in other low-temperature sterilization systems like vapor or plasma processes. So formaldehyde is the correct active ingredient for chemical vapor sterilization.
