Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
Regarding all available data on biotic and abiotic degradation, bioaccumulation and toxicity it can be stated that the substance does not fulfill the PBT criteria (not PBT) and not the vPvB criteria (not vPvB).
The UVCB substance fulfils the screening criterion for persistence. However, as the criteria for toxicity and bioaccumulation are not fulfilled it is not a PBT or vPvB substance. No emission characterisation is performed.
Additional dat on the constituent Monoalkylated DPA:
For the PBT assessment the single constituents were analysed for their bioaccumulation potential. The constituent Monoalkylated DPA (CAS: 36878-20-3 or 27177-41-9) of the registered substance was identified to have the highest bioaccumulation potential of all constituents of the registered UVCB substance.
Monoalkylated DPA revealed in a bioaccumulation study according a BCF <2000 (see chapter 5.3.1). Therefore, based on the results of this study as the (worst case) constituent, it is concluded that also the registered UVCB substance has therefore a BCF <2000.
In conclusion, according to Annex XIII of regulation 1907/2006/EC and the ECHA Guidance on information requirements and chemical safety assessment Chapter R.11 (PBT assessment) this UVCB substance does not fulfil the criterion “bioaccumulative (B)” or “very bioaccumulative (vB)”.
Additional acute data (Monoalkylated DPA):
Additional data for the constituent Monoalkylated DPA indicate that the constituent is neither toxic nor harmful for aquatic organisms in the range of the water solubility (see supporting studies under the respective ecotoxicological endpoints fish , daphnia, algae).
Conclusion on PBT of the registered substance:
In an overall conclusion, the data for the constituent Monoalkylated DPA indicate that the constituent with a BCF < 2000 is not bioaccumulative in terms of the PBT criteria and is neither toxic nor harmful for aquatic organisms in the range of the water solubility.
Therefore, Monoalkylated DPA, identified to be the worst case constituent of the registered substance, does not fulfil the criteria for PBT and therefore also the registered substance is concluded to fulfil not the criteria for PBT.
- Likely routes of exposure:
Regarding all available data on biotic and abiotic degradation, bioaccumulation and toxicity it can be stated that the substance does not fulfill the PBT criteria (not PBT) and not the vPvB criteria (not vPvB).
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).
