- Purity: contains 0.03% water
- Physical state: Liquid
STABILITY AND STORAGE CONDITIONS OF TEST MATERIAL
- Storage condition of test material: in cool, well-ventilated area - Key result
- Melting / freezing pt.:
- < -20 °C
- Atm. press.:
- 101.325 kPa
- Conclusions:
- The freezing point of the test substance was reported as < -20°C.
Reference
The test was performed from ambient down to -20°C. No freezing point was observed within the range of the test (identical results in duplicate test).
Description of key information
The freezing point of the test substance under ambient conditions was determined to be below -20°C in a GLP study according to test method EC A.1 (Younis S, 2012).
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- -20 °C
Additional information
The value used for the CSA is -20 °C, although the results of the test show an unbounded value (< -20 °C).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
