Description of key information
Additional information
No test data are available on bioaccumulation. Testing on bioaccumulation in aquatic organisms is waived based on the absence of a suitable analytical method.
The substance is an UVCB substance, consisting of numerous unknown constituents. The substance is B in the PBT assessment due to the high Log Kow. The log Kow of blown castor oil is >7, and the molecular weight of this substance is between 500 and 5000 g/mol. According to "Guidance on information requirements and chemical safety assessment - Chapter R.11: PBT Assessment", a molecular weight <1100 g/mol is an indicator that the aquatic BCF of the respective substance is higher than 2000 L/kg. The fraction with a molecular weight <1100 is 82%. A molecular weight <700 g/Mol is an indicator that the BCF is higher than 5000 L/kg. This fraction is 5%.
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.
