Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 algae acute toxicity study cannot be considered as a relevant study for classification of chronic toxicity. Indeed, the study duration (3 days) is much shorter than the lag phase before biodegradation starts to occur (at least 5 days based on the biodegradation study). Under actual environmental conditions of chronic exposure, biodegradation by adapted environmental bacteria would permanently limit exposure concentrations and thus algal toxicity. This protective effect is absent in the available algal toxicity study, preventing a relevant conclusion to be drawn from this study concerning chronic toxicity.
- There are no relevant chronic toxicity data in algae, fish and invertebrates, but as the substance is easily biodegradable and has a log Kow of -1, chronic toxicity is not expected.
Aquatic acute:
No classification required in EU/CLP as all LC50/EC50 were > 1 mg/L.
Aquatic chronic:
No classification required for the following reasons:
