Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Based on read-across to studie with blown linseed oil and blown rapeseed oil, blown castor oil is considered to be readily biodegradable.
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
Studies are available for blown linseed oil (BLO) and blown rapeseed oil (BRO). For BLO, one key study and two supporting studies are available. In the key study BLO wastested under the conditions of the conducted modified Sturm test (OECD guideline 301B) and shown to be readily biodegradable. The relative biodegradation values calculated from the measurements performed during the test period revealed 76 and 79% biodegradation of BLO, for the duplicate bottles tested. Also the 10-day window, the criterion for Ready biodegradability, was met. For BRO, two key studies and two supporting studies are available. In one key study conducted according to OECD 301F, BRO was also shown to be readily biodegradable. Based on these data, blown castor oil is expected to be readily biodegradable.
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.
