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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information
Aquatic toxicity data is available for aquatic plants (algae), inverebrates (Daphnia sp.), and vertebrates (fish). PNEC aqua for freshwater, marine water, and for intermittent releases were derived from the most sensitive LC/EC value of the freshwater aquatic toxicity test results. The PNEC STP is based upon a NOEC value from an OECD 209 activated sludge respiration inhibition study utilizing sewage treatment plant microorganisms. There are no toxicity data available for sediment or terrestrial organisms. The PNECs for soils and sediment have been calculated using the the equilibrium partitioning method. A PNEC oral was not calculated as the substance has a low potential for bioaccumulation based upon its octanol-water partition coefficent.
Conclusion on classification
Based upon a fish acute toxicity value of 23 mg/L (>10 and ≤ 100 mg/L) and the substance not meeting the strict requirements to be considered as readily biodegradable, the substance should be classified as Chronic Category 3 under the CLP Regulation.
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).
