Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Key value for chemical safety assessment
- Biodegradation in water:
- under test conditions no biodegradation observed
Additional information
One study investigating the ready biodegradability of DiPE triisononanoate triethylhexanoate (CAS No. 68443-84-5) is available. Based on this GLP study according to OECD 301B a degradation of 18.5% after 28 days is observed (Muckle, 2012). The study was prolonged up to 60 days; the pass level of 60% CO2 evolution; however was not reached. After 60 days 28% biodegradation based on CO2 evolution was observed. Therefore in accordance with Regulation (EC) No. 1907/2006, the substance is regarded as very persistent (v P). The toxicity controls showed that no inhibition of aquatic microorganisms occurred (29 mg/L test material concentration).
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.
