Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Readily biodegradable: 85.6% (inorganic carbon analysis) in 28 days
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
One ready biodegradation study is available for isopropyl isostearate (CAS No. 68171 -33 -5).
This key ready biodegradability study was carried out with isopropyl isostearate (CAS No. 68171-33-5), following a procedure similar to OECD Guideline 310 and according to GLP (King, 1994). Secondary effluent from an activated sludge plant was used as inoculum. During the 28-day test period, biodegradation reached 85.6%, based on inorganic carbon analysis, and the 10-day window criterion was met.
In conclusion, isopropyl isostearate (CAS No. 68171-33-5) can be considered as readily biodegradable according to OECD criteria.
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.
