Auto-ignition temperature: 435°C (5%), 280°C (15%)  (EU A.15)

Key value for chemical safety assessment

Additional information

The auto-ignition temperatures of the 5% and 15% peracetic acid products were 435°C and 280°C, respectively (Mekelburger, 2007). Solutions with concentrations not exceeding 15% peracetic acid are regarded as not flammable under conditions where the liquid is open to the atmosphere. Solutions with more than 15% peracetic acid exhibit both open and closed-cup flash points and vapours can be flammable.
