Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The results from the aquatic toxicity studies are as follows:
LC50 (96 h) fish = >100 mg/L (74.96 mg/L measured concentration)
EC50 (48 h) Daphnia = >100 mg/L
ErC50 (72 h) algae = 98 mg/L
EC50 microorganisms was determined to be >1000 mg/L
and the substance is not readily biodegradable
Acute toxicity
LC/EC50 values are all greater than 1 mg/L therefore, according to Table 4.1.0(a) of the CLP regulation, the substance is not classified for acute (short-term) aquatic hazard.
Chronic toxicity
No chronic data available therefore classification is based on acute (short-term) data for three tropic levels in according with CLP table 4.1.0(b)(iii).
The lowest short-term E(C)50 value is 98 mg/l for algae and the substance is not rapidly degradable, thus meeting the criteria for classification as Category Chronic 3 (ErC50 10 -100mg/l + not rapidly degradable).
Hazardous to the atmospheric environment
The substance is not a chlorofluorocarbon or halogenated substance and is not included in the European list of ozone depleting chemicals (Annex I to regulation (EC) No. 1005/2009. It has a melting point (>360°C) and a low vapour pressure (<9.5 x 10-6 Pa at 25 °C) and therefore will not be present in the atmosphere at concentrations likely to present a danger to the ozone layer.
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.
