Administrative data
Link to relevant study record(s)
- Endpoint:
- melting point/freezing point
- Type of information:
- experimental study
- Adequacy of study:
- key study

- Type of method:
- method to determine freezing temperature
- Melting / freezing pt.:
- < -20 °C
- Atm. press.:
- 1 013 hPa
- Decomposition:
- no
- Sublimation:
- no
- Melting / freezing pt.:
- < 253 K
- Atm. press.:
- 1 013 hPa
- Decomposition:
- no
- Sublimation:
- no
- Conclusions:
- No further testing required (<-20°C).
- Executive summary:
The freezing point of the test substance was determined under GLP according to OECD 102/EU A1 guidelines; the test substance being a liquid at room temperature, the method described in Standard BS4633 for the determination of crystallising point was used.
No freezing point was observed down to -20°C.
Reference
The freezing temperature of the test material has been determined to be less than 253± 0.5 K (< - 20 ± 0.5 °C).
Description of key information
Freezing point < -20 °C.
No further testing is required.
Key value for chemical safety assessment
Additional information
A fully reliable experimental study, conducted under GLP according to a recognized OECD/EU/BS method, is available.
It is considered as a key study. As no crystallisation was observed down to -20°C, the result is expressed as a limit value, and cannot be retained as key data.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
