Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
An experimental data is available for the partition coefficient of d-limonene.
log Kow of d-limonene was determined using HPLC method: 4.38 at 37°C.
Supporting results were obtained at 25°C using shake-fllask method.
Key value for chemical safety assessment
- Log Kow (Log Pow):
- 4.38
- at the temperature of:
- 25 °C
Additional information
log Kow of d-limonene has been measured in a study by RP HPLC (purity above 95%), giving a precise result of 4.38 at 37 °C.
This result was confirmed by supporting studies conducted with d-limonene, but without any information on substance purity. A first study using the shake-flask method has been conducted with d-limonene, giving a range from 4.34 to 4.46 and a mean log Kow of 4.40 at 25 °C . In the second study conducted in the same conditions, log Kow was measured to be 4.5.
Therefore the key value is 4.38.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
