Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Reference
To determine the melting behaviour (three independent single measurements), the test item was measured by DSC between -90 °C and 100 °C with a heating /cooling rate of 10 K/min in 2 cycles. For the measurement a capsulated crusible was used.
6 °C - 16 °C (from first measurement)
6 °C - 15 °C (from second measurement)
6 °C - 17 °C (from third measurement)
The cooling run shows a begin of crystallization at ca. 6 °C. Additionally the heating runs show a glass transition temperature at -48 °C (1st heating run). In the 2nd heating run the test item shows a melting although. The pasty substance is not completely molten at room temperatures.
Description of key information
6 °C - 16 °C at ca. 1013 hPa (OECD 102)
Key value for chemical safety assessment
Additional information
The melting point of the substance was determined by Differential Scanning Calorimetry. The temperature range represents the melting area of crystalline subcomponents. It is not completely molten at room temperature. The cooling run shows a beginning of cristallization at ca. 6 °C.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
