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. WebHowever, pH and temperature do influence peractetic acid activity. Peracetic acid is more effective when the pH value is 7 than at a pH range between 8 and 9. At a temperature of 15 °C and a pH value of 7, five times more peracetic acid is required to affectively deactivate pathogens than at a pH value of 7 and a temperature of 35 °C.
