Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Conclusion on classification
The following relevant key results are currently available for deriving the classification of the substance for the environment:
- Danio rerio: 96h-LC50: > maximum solubility in medium
- Daphnia magna: 48h-EC50: > maximum solubility in medium
- Pseudokirchneriella subcapitata: 72h-ErC50: > maximum solubility in medium; NOEC = maximum solubility in medium
- Not readily biodegradable in an OECD 301B study (read-across substance) and in QSAR
- Log Pow: 1.8 (estimated)
Acute (short-term) aquatic hazard
As the acute E(L)C50 values are >1 mg/L (>100 mg/L), the substance does not need to be classified for this hazard category according to Regulation (EC) No 1272/2008 on classification, labelling and packaging of substances and mixtures (CLP).
Chronic (long-term) aquatic hazard
One chronic value is available, for algae. As there are no chronic values available for fish and crustacea, the chronic classification has to be determined with the available chronic data for algae based on CLP Table 4.1.0 (b)(i), as the substance is not readily biodegradable, and with the available acute data for fish and daphnia magna based on CLP Table 4.1.0 (b) (iii). The most stringent classification is valid;
- CLP Table 4.1.0 (b)(i): As the NOEC is > maximum solubility in medium, the substance does not need to be classified based on this key result.
- CLP Table 4.1.0 (b)(iii): As the E(L)C50 values are > maximum solubility in medium, the substance does not need to be classified based on these key results.
It is therefore concluded that based on the currently available data, the substance does not need to be classified for environmental hazards according to CLP.
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).
