Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 of the representative of the Terpene Hydrocarbon Alcohols has been determined as log P = 3.5 - 5.5 at 25°C in a study equivalent to OECD Guideline 117 (HPLC Method). In this study the lower Kow values represent the Alcohol-type, Ketone type and Ether type. The higher log Kow represents the solely hydrocarbon type constituents of which Terpinolene is the key constituent. On the ECHA website the measured log Kow of Terpinolene is between 4.2 and 4.5, with 4.33 as the arithmetical mean value. As for environmental exposure assessment data on Terpinolene will be used, 4.33 is used as key value.

Additional information
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
