Key result
Melting / freezing pt.:
< -20 °C
Atm. press.:
1 atm
Decomposition:
no
Remarks on result:
other: applicant assessment: FP < -20 ±0.5 °C or < 253.15 ±0.5 K

Applicant assessment indicates: Freezing point: < -20 ±0.5 °C or < 253.15 ±0.5 K, based on freezing of the test items experimentally observed at temperatures << -20 °C or << 253.15 ±0.5 K

Conclusions:
The freezing temperature of the test item has been determined to be < 253.15 ± 0.5 K or < -20 ± 0.5 °C.
Executive summary:

The melting/freezing temperature was determined using EU Method A.1 and OECD TG 102 crystallisation point / freezing temperature method under GLP. The freezing temperature of the test item has been determined to be approximately -41.3°C. The test item has a freezing point (and melting point) significantly < 253.15 ± 0.5 K or < -20 ± 0.5 °C at 1 atmosphere pressure.

Additional information

Key Study : EU Method A.1, 2000: The melting/freezing temperature was determined using EU Method A.1 and OECD TG 102 crystallisation point / freezing temperature method under GLP. The freezing temperature of the test item has been determined to be approximately -41.3°C. The test item has a freezing point (and melting point) significantly < 253.15 ± 0.5 K or < -20 ± 0.5 °C at 1 atmosphere pressure.
