Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Additional information
Aquatic toxicity data are available on all three trophic levels. Chronic toxicity data are available on Daphnia and Algae:
Fish:
In an acute toxicity test according to OECD 203 the LC50 after 96 h was determined to be 9 mg/L (measured). However, emulsifier were used (in concentration above 100 mg/L) and turbidity and partial precipitation was observed in the highest test concentration
Daphnia:
The acute toxicity to aquatic invertebrates was testes in a study according to OECD 203. It resulted in an EC50 after 24 h of 15.3 mg/L. The concentrations were analytically verified. However, emulsifier (in concentration above 100 mg/L) has been used. The chronic toxicity to aquatic invertebrates has been investigated in a GLP guideline study according to OECD 211. After 21 d the NOEC was determined to be 1 mg/L. The LOEC and EC10 after 21 d were 2.8 and 1.75 mg/L, respectively.
Algae:
An ErC50 after 72 h of 1.6 mg/L (mean measured) was determined in a GLP guideline study according to OECD 201 using Scenedesmus subspicatus. The NOEC and the ErC10 were determined to be 0.86 and 0.92 mg/L, respectively.
Therefore, in overall conclusion, the test substance is acutely toxic to aquatic organisms and chronically toxic to aquatic organisms based on long-term data.
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.
