Hydrogen Peroxide
Hydrogen Peroxide is a sterilant chemical used in hospitals and aseptic filling lines in food processing. The concentrations used for sterilization are much higher than the H₂O₂ in the brown bottle you are used to buying at the drugstore. Sterilant chemicals are selected for their ability to kill all forms of microbial life, including bacteria in the very resistant spore form. H₂O₂ has the advantage that it is environmentally friendly, but both the liquid and the colorless vapor are highly reactive and potentially hazardous.
