Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 biodegradability of polysulfide di-tert-nonyl has been read across from polysulfide di-tert-dodecyl. Polysulfide di-tert-dodecyl is not readily biodegradable, with 0% degradation after 28 days.
Key value for chemical safety assessment
- Biodegradation in water:
- under test conditions no biodegradation observed
Additional information
The biodegradability of polysulfide di-tert-nonyl has been read across from polysulfide di-tert-dodecyl. Feil (2009) is a ready biodegradability manometric respiration test, following OECD guideline 301F. This is a GLP compliant, aerobic, activated sludge study. It did not fulfil the validity criteria as the oxygen demand of the inoculum control (medium and inoculum) was 20 mg O2/L rather than the 60 mg/L or above within 28 days as required. Polysulfide di-tert-dodecyl is not readily biodegradable, with 0% degradation after 28 days.
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.
