Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Key value for chemical safety assessment
Additional information
A collection of the aquatic toxicity data and biodegradation in water is available for category members. All found values are listed below.
EC number |
Short-term toxicity to aquatic invertebrates |
Toxicity to aquatic algae and cyanobacteria |
Degradation |
S1 - EC: 918-984-3 |
EC5048 h Daphnia magna: 45 mg/l |
EC50 ca. 76 mg/L
|
readily biodegradable |
S2 - EC: 927-837-2 |
The results obtained on the ecotoxicological endpoint "immobilisation" give an EC5048h superior to the highest tested concentration (i.e 100 mg/l), value expressed in mg/l of the nominal item concentration. No sign of stress was observed on the daphnids during the 48 hours of the experiment. |
ErC50= 136.6 mg/l (extrapolated value expressed in nominal concentration) ErC50= 1.33 g/l (extrapolated value expressed in nominal concentration) NOEC= 10.0 mg/l LOEC = 100.0 mg/l |
readily biodegradable |
Overall, considering (i) aquatic toxicity values for invertebrates and algae and (ii) that the substances are readily biodegradable the registered substance is not expected to be toxic.
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.
