Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information
Conclusion on classification
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.
Short-term Toxicity:
Short-term toxicity to fish (Danio rerio), 96-h LC50 > 100 mg/L (nominal; reference 6.1.1-1)
Short-term toxicity to aquatic invertebrates (Daphnia magna), 48-h EC50 > 100 mg/L (nominal; reference 6.1.3-1)
Toxicity to aquatic algae (Pseudokirchneriella subcapitata), 72-h EC50 > 100 mg/L (nominal, based on growth rate; reference 6.1.5-1)
Long-term toxicity:
Toxicity to aquatic algae (Pseudokirchneriella subcapitata), 72-h EC10 > 100 mg/L (nominal, based on growth rate; reference 6.1.5-1)
Ready biodegradation: readily biodegradability (reference 5.2.1-1)
Bioaccumulation: log Pow = - 0.7 (reference 4.7-1)
Classification according to CLP
The available experimental test data are reliable and suitable for classification purposes under Regulation (EC) No 1272/2008. Based on the data above, the substance has not to be classified for short-term (acute) or long-term (chronic) aquatic toxicity according to Regulation (EC) No 1272/2008 (CLP), as amended for the eighteenth time in Regulation (EU) 2022/692.
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.
