Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
Biodegradation data for the substance itself and read across to Phenol, 4-nonyl-,branched (CAS 84852-15-3) indicate that Benzaldehyde, 2-hydroxy-5-nonyl, oxime, branched (CAS 174333-80-3) is not biodegradable according to OECD criteria. Inherent biodegradability after adaption of inoculum is assumed in water and sediment based on test results with adapted inoculum and simulation test data with branched 4-nonylphenol. In soil, branched nonylphenol is rapidly integrated into organic matter, such as humin, but slowly mineralized. Therefore, in order to apply a very conservative environmental risk assessment approach, persistence of the substance is assumed in the environment.
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.
