Description of key information
boiling/decomposition at 290°C
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 290 °C
Additional information
In the Klimisch 1 non-GLP study from Kintrup (2012) the boiling point of Butanedioic acid, sulfo-, 4-C12-14-alkyl esters, disodium saltswas determined with the DSC method according to OECD 103 and EU method A.2. The test item shows a boiling and /or decomposition at ca. 290 °C (at 1022 mBar) (a decomposition is most likely due to the strong residue in the crucible at ca. 600 °C) according to the definition in the OECD Guideline 103 (mean value from repeat determinations; 1st heating run).From 290 °C the test item shows a boiling and/or thermal decomposition with evaporation of the decomposition products.
For the risk assessment, the lowest possible value will be used, i.e., 290°C. This value was determined at 1022 mbar (102200 Pa). The expected difference of the boiling point from 102200 Pa to101325 Pa is within the measurement accuracy of the method. Therefore, the boiling point as determined at 1022 mbar can be used also for 101 325 Pa.
For the risk assessment a boiling point of 290°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.
