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

log Pow: -0.68

Key value for chemical safety assessment

Log Kow (Log Pow):
-0.68

Additional information

The log Pow for methoxyacetic acid has been estimated with the (Q)SAR method EPIWIN 4.00 provided by US EPA.

The result is well below of any regulatory critical value.

There is a wide range of similar substances with known experimental data giving adequate results by EPIWIN with deviations of < 0.3 log Pow units. See table below.

The (Q)SAR prediction could thus be seen as sufficiently reliable and may be used instead of a experimental value.
