Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

No existing harmonised classification in CLP Regulation Annex VI.


Environmental classification and labelling of a substance is based on data from short-term aquatic toxicity results, and long-term aquatic toxcity results if available, the ready biodegradability of the substance and an experimentally determined BCF (or if absent the measured octanol/water partition coefficient).


 


Data available :


- lowest E(L)C50 value at 2.9 mg/L;


- single EC10 value for algal growth rate > 4.15 mg/L (considered to correspond to the maximum saturation concentration);


- rapidly biodegradable;


- no valid experimental BCF data;


- log Kow > 4.0


 


Short-term aquatic toxicity data is available for all three trophic levels (daphnia, algae and fish). Since all LC50/EC50 values are > 1mg/L, the substance is not classified for short-term hazards to the aquatic environment.


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 ErC10 > 4.15 mg/l), which results in no Chronic classification because the EC10 is > 1mg/L


b) The acute aquatic toxicity data for daphnia and fish (lowest value for fish with a 96 hr LC50 at 2.9 mg/L, so > 1 and < 10 mg/L) and environmental fate data (not rapidly biodegradable) with a log Kow > 4.0, which results in a Chronic 2 classification, and classifying according to the most stringent outcome.


Thus, based on the above data and according to the CLP Regulation 1272/2008/EC & adaptation, the registered substance is classified as Aquatic Chronic 2 (H411) for the environment, without M-factor.
