Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
In a reliable study, performed according to standard method ASTM D-93, the flash point of DIDS was determined to be 226 °C, using the Pensky Martens Closed Cup method (INEOS Enterprises, 2013b). A different standard (closed cup) method (ASTM D-92) found a similar flash point of 252 °C (INEOS Enterprises, 2009b).
Key value for chemical safety assessment
- Flash point at 101 325 Pa:
- 226 °C
Additional information
In a reliable study, performed according to standard method ASTM D-93 (without mention of GLP), the flash point of DIDS was determined to be 226 °C, using the Pensky Martens Closed Cup method (INEOS Enterprises, 2013b). A different standard (closed cup) method (ASTM D-92) found a similar flash point of 252 °C (INEOS Enterprises, 2009b). As DIDS has a flash point above 200 °C, it can be considered as a liquid non-flammable in air, according to chapter R.7a of the IR&CSA guidance (ECHA, 2012b).
Relevant read-across data:
The flash point of DIDA was determined to be 221 °C in a test conducted according to standard (closed cup) method ASTM D-92 (Brassington, 2010b). A value of 223 °C has also been reported for DIDA, calculated by the same method (INEOS Enterprises, 2009b). In an open cup test [with no further details given in the citing source], a flash point of 224 °C was observed (ICI, 1989).
DEHS and DOS have also both been reported to have flash points of greater than 200 °C (INEOS Enterprises, 2009b, c; CHRIP, 2008).
The similarity between the observed flash points supports the use of DIDA, DEHS and DOS for read-across to DIDS.
