Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Pine needle oil undergoes 70% biodegradation after 28 days under a 301F study. Pine needle oil failed the 10-day window. But due to the fact that the substance is identified as an UVCB , the 10-day window condition may be waived and the pass level applied at 28 days according to section 4.1.2.9.5 of CLP COMMISSION REGULATION (EU) No 286/2011 of 10 March 2011.
The curves obtained with the reference substance alone and with Pine needle oil + reference substance show no toxic effect of Pine needle oil on the micro-organisms at the test concentration.
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
Pine needle oil undergoes 70% biodegradation after 28 days under a 301F study. Pine needle oil failed the 10-day window. But due to the fact that the substance is identified as an UVCB , the 10-day window condition may be waived and the pass level applied at 28 days according to section 4.1.2.9.5 of CLP COMMISSION REGULATION (EU) No 286/2011 of 10 March 2011. The curves obtained with the reference substance alone and with Pine needle oil + reference substance show no toxic effect of Pine needle oil on the micro-organisms at the test concentration.
Therefore Pine needle oil is considered as ready biodegradable.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
