Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Remarks on result:
other: Determination carried out in duplicate

Cooling data were obtained in two determinations of melting point/freezing point. In the first determination, temperatures were dropped from 18.4 degrees C to -21.0 degrees C over a period of 0 to 1560 seconds. Readings were taken every 30 seconds. The test article was observed to become slightly viscous during cooling. In the second determination, temperatures were changed from 19.2 degrees C to -21.0 degrees C over 0 to 1830 seconds. Test article was again seen to become slightly viscous during cooling. The interpretation of the results was than the freezing temperature of the test material was less than -20.0 degrees C (253 K).

Conclusions:
Melting/Freezing temperature less than -20 degrees C (253K) for the test article.
Executive summary:

A test conducted using BS4633: Method for the Determination of Crystallizing Point”, designed to be compatible with Method A1 Melting/Freezing Temperature” of Commission Regulation (EC) No. 440/2008 of 20 May 2008 yielded a value of less than –20.0 degrees C (253K) for the test article..
