Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Abiotic degradation:
Air: Based on estimation with the model Aopwin the substance undergoes in air rapid degradation. The DT50 values after reaction with hydroxyl radicals and ozone are 1.1 hours and 38.2 minutes respectively. The substance will not reach the stratosphere and is therefore not considered to be a long-range transported chemical in air.
Ozone depletion: The substance does not have an ozone depletion potential because it does not contain halogens and does not have the capacity to reach the stratosphere (GHS, 3rd Edition, CLP, 2008).
Water: In the aqueous phase a half life for hydrolysis of 3.4 hours at pH 7.5 and 37°C was concluded based on the read across substance.
Biotic degradation:
In a CO2 evolution test biodegradation screening study (OECD TG 301B), after 28 days exposure of domestic activated sludge to 16.0 mg/L (12.0 mg/L TOC) test material, between 22 and 55% biodegradation was observed. Based on these findings the substance is considered to be not readily biodegradable, but can be stated as inherently (primary) biodegradable.
Transport and distribution:
The adsorption potential Koc of the substance was estimated by KOCWIN Molecular Connectivity Index (MCI) as equal to 824.7 L/kg. Based on this value it is concluded that the substance may have a high potential for adsorption to solid surfaces and a low mobility in the water phase.
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.
