Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

- Conclusions:
- The melting temperature of Acetic acid, oxo-, sodium salt, reaction products with ethanolamine and phenol, sodium hydroxide and ferric chloride was tested by DSC.
Reaction and/or decomposition of the test item was observed during DSC experiment starting at 175°C (448K). Melting of the test item was not observed below the temperature at which reaction and/or decomposition started. Based on this, the test item has no melting temperature. - Executive summary:
The melting temperature of Acetic acid, oxo-, sodium salt, reaction products with ethanolamine and phenol, sodium hydroxide and ferric chloride was tested by DSC.
Reaction and/or decomposition of the test item was observed during DSC experiment starting at 175°C (448K). Melting of the test item was not observed below the temperature at which reaction and/or decomposition started. Based on this, the test item has no melting temperature.
Reference
An endothermic effect was observed between 25°C and 175°C directly followed by an endothermic and exothermic effect (starting at 175°C). Based on the weight loss observed during the preliminary test between 50°C and 200°C and according to test item information, the first endothermic effect was due to evaporation of volatile components (i.e. water). The second endothermic effect and exothermic effect were due to reaction and/or decomposition of the test item.
After the experiment, a black residue remained in the sample container (original colour: dark purple to black). The change of the colour indicated reaction and/or decomposition of the test item.
Description of key information
Reaction and/or decomposition of the test item was observed during DSC experiment starting at 175°C (448K). Melting and/or boiling of the test item was not observed below the temperature at which reaction and/or decomposition started. Based on this, the test item has no melting and/or boiling temperature.
Key value for chemical safety assessment
Additional information
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.
