Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

flash point of flammable liquids
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
The study does not need to be conducted because the flash point for liquid organic peroxides is only relevant in the temperature range where the product is thermally stable. Above the SADT (self-accelerating decomposition temperature) of the product flash point determination is not relevant because decomposition products are evolved

Description of key information

The endpoint is waived as the fp is > SADT.

Key value for chemical safety assessment

Additional information

A guideline test with a well detailed study report is available.

The flash point of tert-amyl peroxy-2-ethylhexanoate is 58.5°C at atmospheric pressure (101.3 kPa).

The flash point is greater than the SADT (self-accelerating decomposition temperature), and therefore, the study is not relevant and the study is not used for classification.
