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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information
Daphnia is the most sensitive species in acute and chronic aquatic ecotoxicity tests. Therefore the PNEC freshwater is derived from the chronic NOEC 21d Daphnia of 2 mg/L.
Conclusion on classification
All acute and chronic aquatic toxicity values L(E)C50 for the registration are >1 mg/Land the lowest chronic value is the NOEC reproduction (21d) daphnia of 2 mg/L. All three chronic values have a NOEC > 1mg/L) and this is the basis for the environmental classification under CLP 2nd ATP 2011/286/EC.
The registration substance is not readily biodegradable and not bioaccumulative (log Kow = 1.1, low BCF see IUCLID Chapter 5.3).
Short-term effects
Proposed classification according DSD 67/548/EEC:
no classification required as lowest acute EC50 is > 1 mg/L
Proposed classification according CLP (2nd) ATP 2011/286/EC:
no classification required as lowest acute EC50 is > 1 mg/L
Long-term (chronic) effects
Proposed classification according DSD 67/548/EEC:
classification required as the lowest acute toxicity value is EC50 (48h) Daphnia = 11.8 mg/L and the registration substance is not readily biodegradable: R52/53.
Proposed classification according CLP (2nd) ATP 2011/286/EC:
no classification required as lowest chronic value NOEC reproduction (21d) daphnia is > 1 mg/L.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
