Characteristics of peracetic acid

Peracetic acid (PA) is a highly biocidal oxidizer that sterilizes even in the presence of organic soil. In several studies that compare germicidals, PA was found to be the most active against bacterial spores. In one test involving 23 agents, the antimicrobial activity of PA was the most efficacious against Bacillus thermoacidurans spores, including chlorine. When compared to a variety of disinfectants/sterilants, PA was the most effective against a wide range of bacteria, mycobacteria, viruses, yeasts and fungi.

Studies also show peracetic acid is more efficacious than hydrogen peroxide, formaldehyde, and glutaraldehyde. Additional advantages of PA are its rapid action, ability to remain effective at low temperatures, efficacy in the presence of organic material, and environmentally friendly by-products.
