Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 adsorption coefficient (log Koc) was estimated by three QSAR models:
- KOCWIN v2.00 in EPI Suite (v4.0) - MCI method using log Kow
- KOCWIN v2.00 in EPI Suite (v4.0) - log Kow method
- A model described in Technical Guidance on Risk Assessment (European Chemicals Bureau, 2003) - Part III, Chapter 4, table 4, equation for non hydrophobic substances
The estimated Koc of delta-3-carene is 2339 L/kg (geometric mean of three QSAR models: 1020 L/kg, 6324 L/kg and 1984 L/kg).
