Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Biodegradation in water:
not biodegradable

Additional information

The key studies for Biodegradation are considered to have a reliability rating of 1, however these are being used as read across to a structurally similar substance (EC 701-249-4) as there was no available data to fulfil this endpoint for the test material and so the reliability rating will be reduced to 2, according to the criteria of Klimisch, 1997. 


See category assessment attached in section 13 for justification of read across for this endpoint. Briefly, the analog substance has the same functional group (highly branched alkyl chain attached to the phenate). Therefore, biodegradation will be similar as the additional calcium carbonate will not be relevant for the biodegradation.
