Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 information is available for all three trophic levels (daphnia, algae, fish). The L(E)C50 values are respectively: daphnia 48h EC50 = 24mg/L, Algal 72h ErC50 = 76 mg/L, fish 96h LC50 = 3.22 mg/L. Since all E(L)C50 are > 1mg/L the substance is not classified for acute hazards to the aquatic environment according to the CLP Regulation 1272/2008/EC. 


 


Chronic aquatic toxicity data is not available (i.e. no NOEC or EC10 was determined from the algal inhibition study and chronic studies for daphnia and fish are not required for Annex VIII substances). Therefore, the long-term hazard has been assessed based on the acute aquatic toxicity data (i.e. lowest L(E)C50 value) and environmental fate data. The substance and its underlying constituents are considered readily biodegradable. However, the log Kow range for the constituents of the registered substance range from 3.9 to 5.4 (key study), with the majority of constituents (~89% w/w) have a log Kow > 4. Based on the latter, the substance is considered to have the potential to bioaccumulate for the purpose of classification and labelling. This in combination with the fish 96h LC50 of 3.22mg/L leads to an aquatic Chronic 2 (H411) classification according to the CLP Regulation 1272/2008/EC & adaptation 286/2011/EC.
