Reference
Endpoint:
melting point/freezing point
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
study well documented, meets generally accepted scientific principles, acceptable for assessment
Principles of method if other than guideline:
Column II of REACH Annex VII provides the adaptation that "The study does not need to be conducted below a lower limit of -20°C". Therefore, a limit test is performed to check that the melting point of the substance is lower than -20°C.
GLP compliance:
no
Type of method:
method to determine freezing temperature
Key result
Melting / freezing pt.:
< -20 °C
Remarks on result:
not determinable
Remarks:
Limit test at -20°C

The substance was observed to be a clear liquid at 20°C, and after 48h at -20°C.

Conclusions:
Melting point < -20°C
Executive summary:

The melting point of the test item was determined using a limit test at -20°C; as a sample stored at -20°C for 48h remained liquid, the melting point is < -20°C.

Description of key information

The study does not need to be conducted below a lower limit of - 20 °C according to Regulation (EC) No. 1907/2006, Annex VII, column 2

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-20 °C

Additional information

A limit test was performed and showed that the substance remains a liquid after 48h at -20°C.
