Description of key information
Surrogate substance: ethoxypropoxypropanol: Measured logkow=0.16, Epiwin QSAR value=0.15.
Surrogate substance: methoxypropanol: Measured logkow=<1, Epiwin QSAR value=-0.47
QSAR value: 0.0
Other value available from secondary source: 0.3
Key value for chemical safety assessment
- Log Kow (Log Pow):
- 0
- at the temperature of:
- 20 °C
Additional information
There is no measured data available for the actual substance. Logkow measured values are available from two very similar substances of 0.16 and <1. Calculated values from the Epiwin QSAR model for these two substances are 0.15 and -0.49 respectively.
The QSAR seems to reasonably accurately predict the logKow for two closely related substances for which measured data is available. It therefore appears to be justified to use the QSAR predicted value for the substance to derive the key parameter for this end point.
An extensive justification for read across is contained in the read across justification attached to chapter 13 of this dossier.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
