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

No study has been performed on trisodium orthophosphate for the endpoint 'autoflammability'. An adaptation from the standard testing regime is justified on the following basis:
According to the guidance on information requirements and chemical safety assessment Chapter R.7a Section 7.1.12, the self-ignition test should be carried out using the standard test for relative self-ignition temperature in Annex V of 67/548/EEC which is performed by continuous heating of the substance until either the substance ignites or the limit value (400°C) is reached. A melting point study has been conducted up to a limit of 450°C, no propensity for self-ignition was seen up to this temperature and therefore testing for this endpoint is considered to be scientifically unjustified.
