Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

- PBT status:
- the substance is not PBT / vPvB
- Justification:
Persistence (P) Assessment:
In a ready biodegradation test, Ocimene PQ never reached 60% and therefore, it is considered to be not readily biodegradable. The default position according to the ECHA information requirements R11 is that in the absence of further information the substance must be classified as P and vP. Further information on the degradation potential of Ocimene PQ in the environment is required so, if technically feasible, a hydrolysis study is planned to be undertaken. As such, Ocimene PQ is by default considered Persistent (P) and/or very Persistent (vP) until more data is available.
Bioaccumulation (B) Assessment:
The log Kow of Ocimene PQ is 5.5 and the default position according to the ECHA information requirements R11 is that in the absence of further information the substance must be classified as B and vB. QSARs based on the 4 consituents of this substance were derived using the EPISUITE BCFBAF (2011) models. None of the consituents are considered bioaccumulative as the highest BCF derived was 890 L/kg. As such, this substance is not considered B/vB.
Toxicity (T) Assessment:
As Ocimene PQ is potentially P/vP but not B/vB, a toxicity assessment is not required.
Conclusion of PBT/vPvB assessment
The available data showed that Ocimene PQ is potentially classified as P/vP but is not B/vB. An assessment of T is therefore not required.
