Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

For the substance 3, 6, 9, 12-tetraoxotridecanol: 14.86 by QSAR

For the substance 3,6,9,12,15 -pentaoxahexadecanol: 14.86 by QSAR

These are the predicted results for the two components of this multi-constituent substance.

Key value for chemical safety assessment

pKa at 20°C:

Additional information

There is information available from a QSAR prediction to conclude that dissociation is not a significant property of the components of this multi-constituent substance under any conceivable environmental or biological conditions. This agrees with a qualitative assessment of the molecular structures which suggests that there are no readily dissociable groups within the structures and the substance will not dissociate under any conceivable environmental conditions (taken as pH4 -9). The QSAR suggests that there is no effect of molecular weight on dissociation and the key parameter is representative of the components of the substance that is the subject of this dossier.
