Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
In the CLP regulation the identification of acute (short-term) and long-term hazards is based on the aquatic toxicity of the substance, although this shall be modified by taking account of further information on the degradation and bioaccumulation behaviour, if appropriate.
The substance does not meet the criteria for classification under the CLP regulations for short-term hazardous to the environment based on acute fish, daphnia and algal studies, which gave EC/LC50 values of 6.3 mg/L in fish, 1.4 mg/L in Daphnia and 2.5 mg/L in algae.
The substance does meet the criteria for Category chronic 2. The EC/LC50 values for fish, Daphnia and algae are within the range > 1 to ≤ 10 mg/L, and although the substance is readily biodegradable the Log Pow is ≥ 4 (Log Pow = 4.082).
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.
