Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

- Justification:
Persistence
A ready biodegradability study (OECD 301F) on BPA 2PO (used as a basis for read across to BPA 3PO) showed a long initial lag period consistent with poorly soluble materials. However, once the biodegradation started (approximately Day 9), there was a steady increase in degradation and by the end of the 28 day test period biodegradation had reach 66% and no plateaux was reached. The test substance was therefore considered to be inherently biodegradable but not readily biodegradable. It can be concluded that the substance does not meet the screening criteria for P or vP.
Bioaccumulation
The partition coefficient of the BPA 3PO was determined in accordance with the OECD Guideline for Testing of Chemicals 117. The partition coefficient was calculated for the three major components of the test substance. The results showed a Log Kow of 2.96 (Peak 1), 3.5 (Peak 2) and 3.62 (Peak 3). As these values are all below the threshold of log Kow value of 4.5 it can be concluded that the substance is not B or vB.
Toxicity
The substance is not considered be Toxic in accordance with REACH Annex XIII as
1. Results from acute aquatic toxicity tests from three trophic levels indicate the substance has an EC50 value >0.1 mg/L
2. The substance is not classified as a CMR
3. The substance is not classified as STOT RE category 1 or 2
Conclusion
BPA PO does not meet the criteria for PBT or 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).
