Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
According to Regulation (EC) No. 1907/2006, a substance must fulfil all three criteria for persistence, bioaccumulation and toxicity to be considered as PBT, as listed in part 1 of Annex XIII, and it must fulfil the criteria for persistence and bioaccumulation stated in part 2 of Annex XIII to be considered vPvB. Data for the definitive conclusion on the PBT or vPvB properties according to the criteria set in Regulation (EC) No. 1907/2006, Annex XIII, parts 1 and 2, are not available for all three criteria. Thus, the screening criteria given in the ‘Guidance on information requirements and chemical safety assessment - Chapter R.11: PBT assessment’ (ECHA, 2008) are used as surrogate information to decide whether the substance
may potentially fulfil the PBT or vPvB criteria.
Biodegradation/persistence:
Based on a test result the substance is concluded to be poorly biodegradable. Therefore, it is concluded that the substancedoes fulfil the sreening criteria for persistent (P) or very persistent (vP) as laid down in Annex XIII of the REACH Regulation.
Bioaccumulation:
The recommended BCF models show values significant lower than 2000 L/kg. It can be concluded that the substance does not fulfill the screening criteria for bioaccumulating (B) or very bioaccumulating (vB) as laid down in Annex XIII of the REACH Regulation.
Toxicity:
Based on test results it can be concluded that the L(E)C50 and NOEC values for the substance are not toxic for the environment. It is also concluded that the substance does not need to be classified for CMR or repeated dose toxicity. From this it can be concluded that the toxicity criteria as laid down in Annex XIII of the REACH regulation have not been fulfilled.
Conclusion:
It can be concluded that CAS 94277-77-7 does not fulfill theP(ersistence), B(ioaccumulation) and T(toxicity) criteria as laid down in Annex XIII of the REACH regulation. It can be concludedthat the substanceis not a PBT nor a vPvB substance.
- Likely routes of exposure:
Because the substance does not fulfill the PBT and vPvB criteria, no emission characterisation is performed.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
