- Conclusions:
- No melting and (upon cooling) no crystallization (freezing) temperature was determined for the test substance, using differential scanning calorimetry in accordance with EC A.1 and OECD 102. A glass transition was observed at -40 °C.
Reference
The test item C-SAT 090103 shows no area of melting temperatures (in the 1st and 2nd heating run) up to 100 °C (at ambient temperature the sample is a fluid) according to the definition in the OECD Guideline 102. The heating run shows a glass transition temperature (amorphous components) at -40°C (1st and 2nd heating run). The cooling run shows no crystallisation.
DSC curves: see attached document.
Description of key information
No melting and (upon cooling) no crystallization (freezing) temperature was determined.
A glass transition was observed at -40 °C.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- -40 °C
Additional information
Determined in a study performed in accordance with OECD 102, by differential scanning calorimetry.
