Specific details on test material used for the study:
- Name of test material (as cited in study report): Jeffcat ZR50
- Physical state: Liquid
- Batch: PFW100207
- Composition of test material, percentage of components: contains 0.03% water
- Storage conditions: in cool, well-ventilated area
Key result
Melting / freezing pt.:
< -20 °C
Remarks on result:
other: The test was performed from ambient down to -20°C.
Remarks:
No freezing point was observed within the range of the test

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).

Conclusions:
The freezing point of the test substance was reported as < -20°C.

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).
