- Type of method:
- thermal analysis
- Remarks:
- differential scanning calorimetry
- Key result
- Melting / freezing pt.:
- < -80 °C
- Conclusions:
- No further testing required (freezing < -20°C).
- Executive summary:
The freezing/melting point of the test substance was determined under GLP according to OECD 102/EU A1 guideline, by Differential Scanning Calorimetry (DSC) method. The liquid was first cooled down to -80°C, and no endothermic effect was observed.
The test substance has no freezing/melting point down to a temperature of -80°C at atmospheric pressure.
Reference
The thermograms of the DSC runs are provided in the experimental report.
At ambient conditions, the test item is a liquid. Since no endothermic effects were observed down to a temperature of -80°C, the test item has no freezing/melting point within the investigated temperature range.
Description of key information
No freezing point down to -80 °C.
No further testing required (< -20°C).
Key value for chemical safety assessment
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. As no freezing was observed down to -80°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).
