Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Air: No experimental data on the phototransformation of the substance in air are available. Based on estimation with the QSAR model AopWin the substance undergoes in air rapid degradation after reaction with hydroxyl radicals or ozone. The DT50 values after reaction with hydroxyl radicals are 1.081 hours for the cis-isomer and 1.022 hours for the trans-isomer, respectively. The DT50 values after reaction with ozone are 1.337 hours for the cis-isomer and 1.301 hours for the trans-isomer. These values are not used in the risk characterisation because these are not experimental values. These estimated half-life times are much shorter than 2 days, which is the cut off time for reaching the stratosphere. The substance is therefore not expected to reach the stratosphere and is not a long-range transported chemical in air.
Water: Based on a study performed on the substance the half-life time at 25°C is >1 year at pH 4, 332 days at pH 7 and 41 days at pH 9. It is concluded that the substance is hydrolytically stable under environmental conditions.
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.
