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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

EC number: 223-786-9 | CAS number: 4073-98-7
Endpoint summary
Administrative data
Description of key information
Based on QSAR results and experiemental study on the registered substance, the key ecotoxicity values are as follow:
- Aquatic Invertebrates: 48-h EC50 was 8.885 mg test material/L (experimental value)
- Aquatic algae: 72-h EC50 was 5.87488 mg test material/L (QSAR)
The lowest acute E(L)C50 is higher than 1 mg/L.
Therefore, the substance would not be classified as acute 1 to aquatic organisms in accordance with the classification of the CLP.
Additional information
Short-term toxicity to fish was not provided in the dataset since the tonnage band (1 -10 tonnes/year) does not require that endpoint.
Acute toxicity to aquatic invertebrates (Daphnia magna) has been determined during an experimental study performed under GLP compliance in accordance with OECD 202 guideline.
Acute toxicity to algae has been investigated using using two QSAR models (Leadscope and SciQSAR) incorporated into Danish QSAR Database that replace an OECD 201 study.
CLP Classification proposal
It is proposed to compare submission substance dataset to CLP environmental criteria laid down in CLP Regulation (including 2nd Adaptation to Technical Progress, Com Reg No 286/2011).
Acute aquatic hazard: not classified. Reasoning: lowest EC50 higher than 1 mg/L.
Chronic aquatic hazard: category 2. Reasoning: adequate chronic toxicity data are not available, lowest acute EC50 value is between 1 and 10 mg/L, not readily biodegradable substance.
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.
