Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The ready biodegradability of the substance is considered as a screening study to consider the persistence of the substance in the aquatic environment.

Key value for chemical safety assessment

Biodegradation in water:
under test conditions no biodegradation observed

Additional information

As an organometallic compound, the substance could never be considered to undergo complete biodegradation to CO2 and water. The molecule does, however, include long aliphatic chains that could, in principle, degrade abiotically. In fact, several of the studies available demonstrate a small amount of biodegradation that is likely to be attributable to these aliphatic chains. It is, therefore, considered that while the substance is not readily biodegradable there is evidence of a partial degradation that further demonstrates that the substance is not unduly toxic to the activated sewage organisms.
