Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Type of information:
experimental study
Adequacy of study:
key study
Study period:
Test dates: July 24 to August 6, 2015
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
The study was conducted according to an internationally recognised method, and under GLP. No deviation affected the quality of the study. The substance is adequately characterised. Therefore full validation applies.
according to guideline
EU Method A.9 (Flash-Point)
GLP compliance:
yes (incl. QA statement)
issued 05 March 2015
Type of method:
equilibrium method closed cup
Flash point apparatus:
Setaflash apparatus
Dynamic viscosity of test material:
no data
Specific details on test material used for the study:
- Physical state: Colourless translucent liquid
- Storage condition: Room temperature protected from direct sun light.
Key result
Flash point:
110 °C
Atm. press.:
ca. 1 atm

In a first experiment, the temperature was increased by successive steps of +10°C, using 4 mL of sample: flashing occurred at 110°C.

The measurement was reproduced using a new 4 mL sample, and the temperature was increased by successive steps of +2°C: flashing occurred at 108°C.

Replicate tests showed that no flash was observed at 109°C, but flashing occurred twice at 110°C.

Interpretation of results:
GHS criteria not met
GHS and EU-CLP criteria not met
The flash point of the test substance is above the classification thresholds of 60 °C (CLP criteria) or 93°C (GHS criteria). Therefore, the test substance is NOT a flammable liquid according to CLP and GHS criteria.
Executive summary:

The flash point of the test substance was determined under GLP according to EU A.9 guideline, using a closed cup method with Setaflash apparatus.

After a screening determination, two main runs were performed, and found identical.

The flash point of the test substance was determined to be 110°C.

Description of key information

The substance is NOT classified as flammable liquid neither according to CLP Regulation criteria, nor to UN GHS.

Key value for chemical safety assessment

Flash point at 101 325 Pa:
110 °C

Additional information

A fully reliable experimental study, conducted according to a recognized EU method and under GLP, is available. Therefore it is considered as a key study, and the result is retained as key data.
