Description of key information
Additional information
According to a Mackay Level I model calculation, the main target compartments for 2H-Azepin-2-one, hexahydro-, polymer with 1,6-diisocyanatohexane will be sediment (40.2 %) and soil (39.7 %). The calculated Henry’s Law constant of 0.0010 Pa m³/mol at 20 °C indicates low volatility from surface waters. With an adsorption coefficient of log Koc = 4.05 or higher, a „very high“ sorption potential of the substance to soil or sediment organic matter is expected (Blume scale).
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.
