Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

log Pow = 6.74 - >10

Key value for chemical safety assessment

Additional information

The log Pow of the substance fatty acids, C5 -10 (linear and branched), tetraesters with pentaerythritol (CAS 68424 -31 -7) was determined by QSAR calculation with KOWWIN (v1.68) for the two exemplary components covering both ends of the substance specification.

As the result of the second component (C10 tetra: log Pow = 16.56) exceeds the applicability domain of the model, the value is reported as log Pow >10
