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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
As the PNECs are based on the limit of solubility of the substance in the ecotoxicity tests and are based on doses at which E/LC50s were not reached they will overestimate the toxicity of the substance leading to an exaggerated expression of the risk in the risk assessment.
Conclusion on classification
9.1.3 Short-term toxicity testing on fish: Hooftman & de Wolf (2004), OECD 203 and EU method C.1; LC50>water solubility
9.1.1 Short-term toxicity on invertebrates: Hooftman & de Wolf (2004), OECD 202 and EU method C.2; EC50>water solubility
9.1.2 Growth Inhibition Study on Aquatic Plants: Rufli (1988), OECD 201; ErC50 > water solubility
In accordance with the criteria outlined in Regulation EC No. 1272/2008 (CLP) and Directive 67/548/EEC (DSD), the substance does not meet the critieria for classification as dangerous to the environment.
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.
