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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Bioaccumulation study conducted in accordance with "Test method for new chemical substances" determined in Regulation Number 392 (1974).
Key value for chemical safety assessment
- BCF (aquatic species):
- 2 dimensionless
Additional information
The experimentally-determined log Kow of 0.05 is substantially below the criterion of log Kow ˂ 3 at which bioaccumulation testing is not indicated, as described in Regulation (EC) No.1907/2006, Annex IX, Column 2. In addition, the bioaccumulation study of the substance in carp indicated that bioconcentration is not of concern; the BCF value ≤ 2 from the low concentration test and BCF≤ 0.7 from the high concentration test are each substantially below the definitive criteria for both bioaccumulative (> 2,000 L/kg) and very bioaccumulative (>5,000 L/kg). Therefore, bioaccumulation is not expected in the aquatic compartment.
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.
