Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information

not self-heating, not self-ignitable 

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
302 °C

Additional information

The substance is a solid with a melting point > 160 °C. Not self-ignitable is also the high water content (ca. 73%) formulation of the substance: in a test according to ASTM E 659-78 (2005), there was no auto-ignition up to 450 °C at 101.5 kPa.

For a chemical safety assessment, the read-across value of 302 °C can be taken from a similar alkyl sulfate: Sulfuric acid, mono-C12-14-alkyl esters, sodium salts (CAS 85586-07-8, guideline VDI 2263), as in this case water was eliminated prior to the experiment.
