Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
For the test substance the base set data are available. A guideline study for short-term toxicity is available for freshwater fish. The critical acute effect concentration is a 96-h LC50 value of >1000 mg/L in zebrafish (Danio rerio) (CG, 1987). A guideline short-term toxicity study is available for aquatic invertebrates. The critical effect concentration is a 24-h EC50 value of >1000 mg/L in Daphnia magna (RCC, 1987). A guideline growth inhibition study is available for freshwater algae. The critical effect concentrations are a 72-h ErC50 value of >100 mg/L and a 72 -h NOErC of 100 mg/L in Scenedesmus subspicatus (RCC, 1996). The ErC50 value of 100 mg/L is used for calculation of the aquatic PNECs. As no data on the toxicity towards freshwater or marine sediments or soil are available, the PNECs for sediments and soil are calculated with the Equilibrium Partitioning Method (using EUSES v2.1). Long-term studies with fish and invertebrates are not available. For the assessment of toxicity to microorganisms, a guideline respiration inhibition study with a mixed culture of bacteria is available. The critical effect concentration is a 3-h IC50 value of >100 mg/L (CG, 1987). This value is used for calculation of the PNEC-STP.
Conclusion on classification
Based on all available data for fish, aquatic invertebrates and algae, the test substance needs not to be classified according to Directive 67/548/EEC - Classification, Packaging and Labelling of Dangerous Substances or according to Regulation (EC) No. 1272/2008 on Classification, Labelling and Packaging of Substances and Mixtures (CLP))
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
