Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 all three trophic levels. The L(E)C50 values are 2.4mg/l, 2.7mg/L and 3.6 mg/L in fish, invertebrates and algae respectively. Since all EC50 values are > 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 NOEC = 0.26 mg/l), which for a non-rapidly degradable substance results in a Chronic 2 classification, and

b) The acute aquatic toxicity data for the other 2 trophic leves (Daphnia 48h EC50 = 2.7 mg/L, Fish 96h LC50 = 2.4mg/L) and environmental fate data (not readily but inherently biodegradable; log Kow of 3.1 -3.2), which results in a Category Chronic 2 classification,

and classifying according to the most stringent outcome.

Thus it is concluded that the substance is classified Aquatic Chronic 2 (H411) according to the CLP Regulation 1272/2008/EC & adaptation 286/2011/EC.

Under the old DSD regulation the substance would be classified as R51/53 (toxic to aquatic organisms and may cause long-term adverse effects in the aquatic environment).
