- Type of method:
- method to determine freezing temperature
- Key result
- Melting / freezing pt.:
- < -40 °C
- Atm. press.:
- 993.4 mBar
- Decomposition:
- no
- Conclusions:
- At the end of the measurement (-40°C) the test item was still liquid.The freezing point of test item was stated at <-40°C.
- Executive summary:
The study was performed in order to determine the freezing point of test item according to OECD 102, resp. EU A.1 guideline.
At the end of the measurement (-40°C) the test item was still liquid.The freezing point of test item was stated at <-40°C.
Reference
The temperature of test item decreased continuously in the main test. The test item was cooled down to approximately -40 °C.
A freezing point according to the criteria of the guidelines could not be determined down to approximately -40 °C. No typical observation concerning a phase transition was observed. At the end of the measurement the test item was liquid. The atmospheric pressure was 997.8 mbar (start) to 993.4 mbar (end).
Description of key information
The freezing point of test item was stated as < -40°C.
The test item was still liquid at -40°C.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- -40 °C
Additional information
A fully reliable experimental study, conducted according to a recognized OECD/EC method and under GLP, is available. It is considered as a key study.
