Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Short description of key information on bioaccumulation potential result:
No sign of absorption seen in any of the available in vivo toxicology studies.
Key value for chemical safety assessment
Additional information
No specific study was performed on the absorption / distribution / metabolism / excretion (ADME) of NC-4, but data are available fron the in vivo toxicology studies. No sign of absorption has been abserved in any of the available studies.
The physico-chemical properties of NC-4, particularly its very low water solubility and its relative high molecular weight may be limiting factors in the amount of material that is absorbed after oral or dermal exposure. Due to its vapour pressure, NC-4 is unlikely to be available under a vapour state.
A full discussion of the assessment is provided in the attached document.
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.
