Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
decomposition at 221 °C
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 221 °C
Additional information
In the Klimisch 1 non-GLP study from Kintrup (2012) the melting point of Butanedioic acid, sulfo-, 4-C12-14-alkyl esters, disodium salts was determined with the DSC method according to OECD 102 and EU method A.1. The test item did not show melting up to 221°C. Up to 221 °C the sample shows a weight loss of ca. 4-5 weight%. From 221 °C the test item shows most probably a thermal decomposition with melting (a melting > 300°C can not be excluded, due to the information of the capillary method, the decomposition products seem to start melting at temperatures > 300°C) and evaporation of the decomposition components. A vaporization of significant parts of the test item cannot be completely excluded.
For the risk assessment a melting point of 221°C will be used.
This information is considered to be relevant and reliable for the further risk assessment.
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.
