Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Waiver: low potential for bioaccumulation based on log Kow <3.

Key value for chemical safety assessment

Additional information

Reliable measured bioconcentration information is not available for KEL 3587, therefore a waiver is justified. 

In accordance with Column 2 of REACH annex IX, the bioaccumulation test on terrestrial organisms need not be conducted if the substance has a low potential for bioaccumulation (for instance a log Kow <3) and/or a low potential to cross biological membranes or if direct and indirect exposure of the aquatic compartment is unlikely. The partition coefficient of KEL 3587 was determined in a reliable study (Frischman 2012) where the measured Kow is <=- 0.46. Therefore, KEL 3587 is considered to have low potential for bioaccumulation. Additionally, the substance is rapidly biodegradable and therefore, exposure to terrestrial organisms is unlikely. No further testing is required.
