Remarks on result:
other: see the comments on "any other information on results incl. tables"

No crystals evidence have been noticed in all measurements. According to Guidance on information requirements and chemical safety assessment Chapter R.7a: Endpoint specific guidance, May 2008, Guidance for the implementation of REACH the study does not need to be conducted below the determination lower limit of -20 °C. The freezing point was determined to be below of -30 °C.

Conclusions:
The freezing point of the test substance was determined to be < -30 ºC.
Executive summary:

A freezing point determination test was performed in accordance with EU Method A.1 and OECD Guideline 102 (PN-ISO 1392:2002). The freezing point of the test substance was determined to be lower than -30 ºC since no crystal evidence were noticed in all three measurements.

Description of key information

Key study: EU Method A.1 and OECD Guideline 102. GLP study. The freezing point was determined to be < -30 ºC.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-30 °C
