Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Environmental classification and labelling of a substance is generally based on data from short-term aquatic toxicity results, the ready biodegradability of the substance and an experimentally determined BCF (or if absent the measured octanol/water partition coefficient). Available adequate chronic toxicity data is also relevant for the assessment of long-term aquatic hazards (Regulation 286/2011/EC).

              

Short-term aquatic toxicity data is available for two trophic levels (daphnia and algae). The lowest short-term EC50 is for daphnia, which is a 48-hour EC50 of 27.0 mg/l. Since the EC50 is > 1mg/L the substance is not classified for short-term hazards to the aquatic environment according to the CLP Regulation 1272/2008/EC.

 

Chronic aquatic toxicity data is only available for one trophic level (algae). Therefore, the long-term hazard has been assessed based on both:

a) The chronic aquatic toxicity data for algae (72 hr EC10 = 279.03 mg/l), which results in non chronic classification because the value is >= 1 mg/L and substance readily biodegradable,

and

b) The acute aquatic toxicity data for daphnia (EC50 = 27.0 mg/L) and environmental fate data (readily biodegradable and log Kow 2.8). This results in a non chronic classification,

and classifying according to the most stringent outcome.

 

Thus it is concluded that the substance is non classified for the environment according to the CLP Regulation 1272/2008/EC & adaptation 286/2011/EC.
