Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 2 trophic levels (daphnia and algae). Based on valid studies the determined EC50 values are respectively, for Daphnia and algae, 11.09 and 15.4 mg/L. Since all EC50s are > 1mg/L the substance is not classified for short-term (acute) 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 (chronic) hazard has been assessed based on both:
a) The chronic aquatic toxicity data for algae (NOEC = 1.43 mg/L) which results in no chronic classification (> 1mg/L, not rapidly biodegradable), and
b) The acute aquatic toxicity data for daphnia (EC50 = 11.09 mg/l) and environmental fate data (not readily biodegradable and log Kow of >4.0), which results in a chronic classification Cat 3 and therefore classifies Givescone according to the most stringent outcome.
Thus it is concluded that the substance is classified for long-term (chronic) aquatic cat 3 (H412) hazard according to the CLP Regulation 1272/2008/EC & adaptation 286/2011/EC.
According to the old DSD regulation, Directive 67/548/EEC, the substance would be classified as R52/53 for environmental hazards.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
