WebPeroxyacetic acid is a combination of two important and versatile compounds: hydrogen peroxide and acetic acid. The two chemicals combine to form a new compound, peroxyacetic acid. This is an equilibrium reaction where over a period of hours, peroxyacetic acid is formed in situ by assuming elements of both reagents to form the new compound. Webwater. However, commercial peroxyacetic acid solutions are primarily multi-component mixtures of peroxyacetic acid, acetic acid, hydrogen peroxide, and water. During the process of water treatment, peroxyacetic acid and hydrogen peroxide (H 2O 2) often coexist, which limits further investigation on the properties of peroxyacetic acid.
WebPeracetic acid will inactivate gram-positive and gram-negative bacteria, fungi, and yeasts in <5 minutes at <100 ppm. In the presence of organic matter, 200-500 ppm is required. For viruses, the dosage range is wide (12-2250 ppm), with poliovirus inactivated in yeast extract in 15 minutes with 1500 to 2250 ppm.
