Description of key information
There is currently no validated test method available for the determination of adsorption coefficients of nanomaterials that are not highly soluble. The OECD test guideline 106 is not applicable (cf. NANoREG EU FP7 funded project, Deliverables Reports 2.3 and 2.9, 2015/6 and ECHA 2017, Guidance on information requirements and chemical safety assessment, Appendix R7 -1 for nanomaterials).
Key value for chemical safety assessment
Additional information
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.
