Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

- Physical state: Liquid
- Lot/batch No.: PFW100241
- Other: Sample stored in cool well-ventilated area prior to testing
Key result
Melting / freezing pt.:
< -20 °C
Remarks on result:
other: Atmospheric pressure not reported; ambient conditions are anticipated.
The freezing temperature of the test substance was concluded to be below -20 °C under ambient conditions.

Description of key information

The freezing point of the test substance under ambient conditions was determined to be below -20°C in a GLP study according to test method EC A.1 (Younis, 2011).

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-20 °C

Additional information

The value used for the CSA is -20 °C, although the results of the test show an unbounded value (<-20 °C)
