Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 method:
method to determine freezing temperature
Key result
Melting / freezing pt.:
< -25 °C
Remarks on result:
not determinable

In a trial determination, the test material did not solidify as the temperature was decreased from ambient temperature down to -25 °C. No further testing was necessary, as the test material was still liquid at -25 °C.

Conclusions:
The freezing temperature of the test material was determined to be less than -25 °C.
Executive summary:

The freezing point of the test material was determined in accordance with the standardised guidelines OECD 102 and EU Method A.1 under GLP conditions using a suitable apparatus (Seta Freezing Point Apparatus, Stanhope Seta Ltd.).

Under the conditions of this study, the freezing temperature of the test material was determined to be less than -25 °C.

Description of key information

Under the conditions of this study, the freezing temperature of the test material was determined to be less than -25 °C.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-25 °C

Additional information

The freezing point of the test material was determined in accordance with the standardised guidelines OECD 102 and EU Method A.1 under GLP conditions using a suitable apparatus (Seta Freezing Point Apparatus, Stanhope Seta Ltd.). The study was awarded a reliability score of 1 in accordance with the criteria set forth by Klimisch et al. (1997).

Under the conditions of this study, the freezing temperature of the test material was determined to be less than -25 °C.
