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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information

96h LC50 >100 mg/l
Key value for chemical safety assessment
Fresh water fish
Fresh water fish

Additional information
Data are available from three studies summarised as
Ciba-Geigy Ltd. 96hr EC50 >100 mg/l
NITE 48hr EC50 >100mg/l
Shell Chemie 96hr LC0 >1.2mg/l
The substance is highly insoluble in water and all data demonstrate a lack of effects above the limit of solubility. While the data from NITE demonstrate a lack of effects the experiment has been ended before the 96 hour exposure period has elapsed and hence the data from Ciba Geigy are included for CSA.
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.
