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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Ecotoxicological Summary
Administrative data
Hazard for aquatic organisms
Hazard for air
Hazard for terrestrial organisms
Hazard for predators
Additional information
As the substance poses no hazard to aquatic organisms, and consequently not to the various environmental compartments (freshwater, marine water, STP, sediment (fresh and marine water), soil, air, predators), no classification is warranted.
Aquatic acute toxicity
48 h, EC50 (Daphnia magna): > 100 mg/L (nominal concentration)
72 h, ErC50 (Raphidocelis subcapitata): > 100 mg/L (nominal concentration)
Aquatic chronic toxicity
72 h NOEC (Raphidocelis subcapitata): 100 mg/L (nominal concentration)
Based on read-across from the source substance biodegradation study: not readily biodegradable: 1 % (based on % CO2 evolution after 28 days OECD 301 B)
Partition coefficient: log Kow = -2.36 at 20 °C
Classification according to CLP
The available experimental test data are reliable and suitable for classification purposes under Regulation (EC) No 1272/2008. The test substance was found to be not readily biodegradable under the test conditions. The most sensitive test for the aquatic compartment was the toxicity test to algae. This study revealed a 72 h EC50 of > 100 mg/L and the 72 h NOEC of a toxicity to alga and cyanobacteria test with the test substance was determined to be 100 mg/L. Based on these results, the substance is neither classified as short-term (acute) aquatic toxicity nor classified as long-term (chronic) aquatic toxicity according to Regulation (EC) No 1272/2008 (CLP), as amended for the fifteenth time in Commission Regulation (EU) 2020/1182.
Conclusion on classification
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.
