Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Koc of d-limonene has been estimated by 3
QSAR methods.
1. KOCWIN from EPISUITE 4.0 using CAS number as input and the Molecular
Connectivity Method (MCI): Koc = 1120 L/kg
2. KOCWIN from EPISUITE 4.0 using an experimental log Kow of 4.38 and
CAS number 5989 -27 -5 as input: Koc = 6324 L/kg
3. equation of Sabljic and Güsten (1995) for non hydrophobic susbtances
as reported in TGD (2003) using a log Kow of 4.38: Koc = 1984 L/kg
The geometric mean of the 3 Koc predicted values is considered as key value = 2413 L/kg.
Key value for chemical safety assessment
- Koc at 20 °C:
- 2 413
Additional information
ECHA Guidance (chapter R.7.a, paragraph R.7.1.15) recommends to calculate the Koc endpoint value as the geometric mean of results obtained by QSARs.
This geometric mean value is considered as the endpoint defining the substance for adsorption and is used as input parameter for Environmental Risk Assessment.
[LogKoc: 3.383]
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
