Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Remarks on result:
other: see Remarks
Remarks:
5 %

The measured lowest ignition temperatures of the main test are > 300 °C and do not differ by more than 20 °C, thus the test is satisfactory. The individual results are 455, 436, 438 °C respectively. The auto-ignition temperature is defined as the lowest temperature of all single results of the main test, but rounded down to multiples of 5 °C.


Auto-ignition temperature: 435 °C

Conclusions:
The auto-ignition temperatures of the 5% PAA products was 435 °C.
Executive summary:

The auto-ignition temperatures of the 5% PAA products was 435°C. Solutions with PAA concentrations not exceeding 15% PAA are regarded as not flammable under conditions where the liquid is open to the atmosphere. Solutions with more than 15% PAA exhibit both open and closed-cup flash points and vapours can be flammable. No derivation from the guideline.

The measured lowest ignition temperatures of the main test are < 300 °C and do not differ by more than 10 °C, thus the test is satisfactory. The individual results are 280, 280, 280 °C respectively. The auto-ignition temperature is defined as the lowest temperature of all single results of the main test, but rounded down to multiples of 5 °C.


Auto-ignition temperature: 280 °C

Conclusions:
The auto-ignition temperature of the 15% PAA products was 280 °C.
Executive summary:

The auto-ignition temperature of the 15% PAA products was 280 °C. Solutions with PAA concentrations not exceeding 15% PAA are regarded as not flammable under conditions where the liquid is open to the atmosphere. Solutions with more than 15% PAA exhibit both open and closed-cup flash points and vapours can be flammable. No derivation from the guideline. 

Description of key information

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.
