Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
- ErCr50 (72h) algae = 0.00361 mg/L (geometric mean of the measured concentrations) with 95% confidence limits of 0.00287 - 0.00509 mg/L
- EC50 (48h) daphnies = 0.011 mg/L (measured concentrations) with 95% confidence limits of 0.0094 - 0.013 mg/L
- NOECchronic fish = 40 µg/L (nominal concentrations, based on measured concentrations showing a stable exposure concentration within 80 -120% of nominal over the entire exposure period)
- NOECchronic daphnids = 0.308 µg/L (geometric mean of the measured concentrations
- EC50 microorganisms: no study available, but during the biodegradation test, no microbiological toxicity was observed.
The results from the aquatic toxicity studies are as follows:
The classification for acute toxicity based on the lowest short term data for algae (ErC50 = 3.61 µg/l) is Aquatic Acute 1 H400 with a M factor of 100. With no biodegradation the classification Aquatic chronic 1 is also relevant with a M factor = 100.
Based on the results from the short-term aquatic toxicity tests and since the substance is not biodegradable, the substance is classified as Aquatic Acute 1 (Hazard statement H400 - Factor M = 100) and Aquatic Chronic 1 (Hazard statement: H410 - Factor M = 100) according to the CLP Regulation 1272/2008.
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).
