Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The partition coefficient was determined in a Weight of Evidence approach. 
The partition coefficient of terpinolene monoconstituent is 4.33 (arithmetical mean value of 3 results).

Key value for chemical safety assessment

Log Kow (Log Pow):
4.33

20 °C

Additional information

A weight of evidence approach was applied to determine the partition coefficient of terpinolene monoconstituent.

Two literature data and one valid QSAR value have been gathered (very similar values). A mean value is calculated to give a representative

estimation of the partition coefficient of terpinolene monoconstituent. This arithmetical mean value can be retained as key value for chemical safety assessment.
