Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Boiling point
Administrative data
Link to relevant study record(s)
- Endpoint:
- boiling point
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because the substance is a solid which melts above 300°C

Description of key information
Boiling point: HEDP-H melts above 450°C.
Key value for chemical safety assessment
Additional information
The requirement to conduct a boiling point study for the substance is waived because the substance has a melting temperature of >450°C. This statement is supported by a recent, reliable DSC test which demonstrates that HEDP acid does not melt below 450°C. The DSC thermograms show evidence of loss of water at about 100°C.
In available secondary sources to which reliability could not be assigned, initial boiling point values of approximately 100°C, 104°C, 105°C AND >100°C were reported for the substance.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
