Peracetic acid is never bought in unstabilized methods Which explains why it is thought to be eco-friendly.[51] Peracetic acid is often a colorless liquid and the molecular components of peracetic acid is C2H4O3 or CH3COOOH.[fifty two] Much more lately, peracetic acid is getting used throughout the environment as more and more people are making use of fumigation to decontaminate surfaces to cut back the risk of COVID-19 and other disorders.[fifty three] Potential for chemical sterilization of prions[edit]
