Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Applicant's summary and conclusion

Conclusions:
Observed peaks were between -10.5 to 27.1 oC and this range has been reported here for melting point.
Executive summary:

A range of thermal events were observed, possibly indicating inhomogeneity of the tets item when tested. The test item did appear to be multi-phased on standing, with both a solid phase and an oily phase being visually observed, but was mixed before testing. Two main thermal events were measured, one at -10.5 oC abd then a broader event, encompassing three measurements, with the maxima giving a temperature measurement of 17.1 oC. The temperatures quoted do correspond with both solid and liquid phases being observed at ambient lab temperature (app. 21 to 25 oC). Observed peaks were between -10.5 to 27.1 oC and this range has been reported here for melting point.
