Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
- Name:
- Legal entity composition
- Type of composition:
- legal entity composition of the substance
- Reference substance:
- Legal entity composition
- PBT status:
- the substance is not PBT / vPvB
- Justification:
Persistence:
The substance is readily biodegradable, but failing 10 -day window, and may therefore be considered to be “not P/vP”.
Bioaccumulation:
The substance has a log Kow of ≥4.5. As no experimentally determined BCF is available, the substance is assessed as potentially "B (and vB)” based on the log Kow screening criterion alone.
Toxicity:
There is no evidence of CMR properties or chronic toxicity as specified in REACH Annex XIII. The substance has E(L)C50 values above the solubility limit in test medium for 3 trophic species and a NOEC value of >0.01 mg/L. However, the substance has a log Kow of >4, and based on available short-term toxicity data it cannot be concluded that algae are significantly more sensitive than the other taxonomic groups. Therefore, no conclusion can be reached based on the currently available information.
Reference
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
