Specific details on test material used for the study:

SOURCE OF TEST MATERIAL
- Source and lot/batch number of test material: PFW100207
- 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

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).
