Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Type of information:
experimental study
Adequacy of study:
key study
Study period:
12/2007 to 03/2008
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
guideline study without detailed documentation
The study was conducted according to an internationally recognised method. The substance is adequately defined (with certificate of analysis). However, some experimental data are missing. Therefore validation applies with restrictions.
according to guideline
other: ASTM D87-87
equivalent or similar to guideline
other: BS 4695
equivalent or similar to guideline
OECD Guideline 102 (Melting point / Melting Range)
GLP compliance:
Type of method:
method to determine freezing temperature
Key result
Melting / freezing pt.:
< -9.5 °C
Remarks on result:
other: accuracy: +/-0.5 °C

No data on individual measurements (at least two repetitions required).

Executive summary:

According to ASTM D87-87 guideline (equivalent to OECD/EC), the freezing point of the test material was measured at a temperature of -9.5 °C.

Description of key information

Freezing (i.e. liquid-to-solid transition) occurs at the temperature of -9.5°C.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-9.5 °C

Additional information

A reliable study, conducted by the registrant according to a method equivalent to OECD/EC, is available. Despite restrictions due to missing details, it is considered as a key study, and the result is retained as key data.
