Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Type of information:
experimental study
Adequacy of study:
key study
Study period:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
according to guideline
other: GB/T 261-2008 “Determination of flash point. Pensky-Martens closed cup method”
Version / remarks:
GB/T 261-2008
Principles of method if other than guideline:
The test portion is placed into the test cup of a Pensky-Martens apparatus and heated to give a constant temperature increase with continuous stirring. An ignition source is directed through an opening in the test cup lid at regular temperature intervals with simultaneous interruption of stirring. The lowest temperature at which the application of the ignition source causes the vapor of the test portion to ignite and flame propagate over the surface of the liquid is recorded as the flash point at the absolute barometric pressure. This temperature is corrected to standard atmospheric pressure using a specified formula.
GLP compliance:
not specified
Type of method:
closed cup
Flash point apparatus:
Pensky-Martens apparatus
Flash point:
ca. 47 °C
Atm. press.:
101.3 kPa
Based on the determination results, the flash point of sample is 47.0 °C.
Executive summary:

Report the flash point, corrected to standard atmospheric pressure, rounded to the nearest 0.5 °C.

Based on the determination results, the flash point of sample is 47.0 °C.

Description of key information

The flash point was determined according to " Pensky-Martens closed cup method" in GB/T 261-2008 “Determination of flash point".

Key value for chemical safety assessment

Flash point at 101 325 Pa:
47 °C
