PBT status of the assessed substance:

Results of detailed PBT / vPvB assessment

Persistence

Evidence of non-P / non-vP properties

Screening criteria

Criteria based on Annex XIII of REACH

Further information for the PBT assessment is necessary

Remark:

A readily biodegradable study performed according to the guideline OCDE 301B in 2008 is the only study available for the substance, showing that the substance is not readily biodegradable with a degradation of 45% after 28 days. However, the test methodology used is stringent, and it does not necessarily mean that the substance will not be degradable under environmental conditions.
The substance is potentially P or vP. Further investigations are needed to evaluation if the P or vP criteria is fulfilled.

Conclusion

Conclusion on P / vP properties:

No conclusion can be reached based on available information

Bioaccumulation

Evidence of non-B / non-vB properties

Screening criteria

Criteria based on Annex XIII of REACH

Further information for the PBT assessment is necessary

Remark:

No data concerning bioaccumulation of the substance is available.
The substance is a UVBC with a molecular weight > 1400, a Log Kow between 7.54 and the infinite and is insoluble in water (< 0.0075 mg/l).
In case of missing data, the Log Kow is widely used to estimate the potential of a substance to bioconcentrate.
It is recognised that linear correlations are appropriate for substance with log Kow values in the range of 1 to 6. More hydrophobic substances can have lower BCF values than predicted with linear correlations methods.
However, the calculated Log Kow is not a reliable value (since it tends to the infinite) and the substance has surfactive properties, therefore Log Kow might not be a good indicator to estimate the potential of bioaccumulation of the substance.
If the P or vP criteria is confirmed, further information for the B/vB assessment will be needed

Conclusion

Conclusion on B / vB properties:

No conclusion can be reached based on available information

Toxicity

Evidence of non-T properties

Criteria based on Annex XIII of REACH

Further information for the PBT assessment is necessary

Remark:

Based on the available aquatic toxicity study with daphnia, the T criteria is probably met. However, due to incertainties of the results of the study, and if the P and B criteria are confirmed, further evaluation will be needed to evaluate this endpoint.
