Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 assessment
Administrative data
PBT assessment: overall result
- PBT status:
- the substance is not PBT / vPvB
- Justification:
An assessment of the PBT status of the substance has been made using all available data. The information available suggests that the substance does not meet the PBT screening criteria as outlined in Directive 2006/121/EC (Appendix A).
Persistence Assessment
A manometric respirometry test (EU Method C.4-D) showed that the substance is ready biodegradableand therefore it can be regarded as not persistent.
BioaccumulationAssessment
In the absence of a measured BCF value, the log KOWcan be used as a screening criterion for bioaccumulative potential (i.e. >4.5). As the log KOWof the substance is below 4.5, the B/vB criterion is not met. Therefore the substance is identified as not B.
Toxicity Assessment
The acute effect information for all three trophic levels is much higher than the screening criterion of 0.1 mg/l. It can therefore be expected that the substance is not toxic towards aquatic organisms.
Summary and Overall Conclusions on PBT or vPvB Properties
The overall conclusions, based on the present available data, of the preliminary PBT assessment are that the (screening) criteria for PBT/vPvB are not met and that further testing in the scope of the final PBT assessment is not considered to be required.
Emission Characterisation
The substance is not a PBT/vPvB substance, therefore the emission characterisation does not need to be conducted.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
