Peroxygen

Definition

Peroxygen compounds are a class of chemicals that release oxygen, making them effective disinfectants and sterilants. They are often used to control microbial growth in various settings, including healthcare and food industries.

5 Must Know Facts For Your Next Test

1. Peroxygens like hydrogen peroxide and peracetic acid are strong oxidizing agents that disrupt cell membranes and denature proteins.
2. Hydrogen peroxide can be used at different concentrations for antiseptic (3%) or sterilization purposes (>30%).
3. Peracetic acid is effective against a broad spectrum of microorganisms, including bacteria, fungi, viruses, and spores.
4. Peroxygen compounds break down into non-toxic byproducts such as water and oxygen, making them environmentally friendly.
5. The effectiveness of peroxygens can be influenced by factors such as concentration, contact time, temperature, and presence of organic matter.
