Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
- 0.436, 0.51 (measured values for very similar substances)
- 0.02 (QSAR prediction)
Source substance triethylene glycol butyl ether
QSAR prediction for 3,6,9,12-tetraoxahexadecan-1-ol : -0.26
Key value for chemical safety assessment
- Log Kow (Log Pow):
- 0.25
- at the temperature of:
- 20 °C
Additional information
A measured value is available for a the source substance triethylene glycol butyl ether. A reliable QSAR indicates that the partition coefficient will decrease with the increase in molecular size going from the source to the target substance. The QSAR can be used to bridge from the measured data on the source substance to the target substance. Since the QSAR seems to over predict by around 0.5, on this basis, the logKow for 3,6,9,12-tetraoxahexadecan-1-ol to be ~0.25. This is the value used for the key parameter for this end point.
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).
