Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information
Weight of evidence approach, 1975 and 2008: The melting/freezing temperature is documented in published literature (handbooks/data-tables). The melting temperature of the test item has been reported to be greater than 298 K or greater than 25 °C at 1 atmosphere pressure (reported melting point 42.8 - 43.8 °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).
