Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
Phototransformation in air
Stability of the substance in the atmosphere was calculated using the software AOPWIN (v 1.92). It is predicted that the substance will be degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals. The half-life for this reaction in air is estimated to be between 4.6 and 13.8 hours, at different test conditions. The most conservative value was selected.
Hydrolysis
In accordance with REACH Regulation 1907/2006, Annex VIII, Column 2 hydrolysis as a function of pH does not need to be determined as the substance is readily biodegradable.
Stability of the substance against hydrolysis was calculated using the computer program HYDROWIN (v 2.00). A base-catalysed second-order hydrolysis rate constant of 0.03486 L/mole-sec was estimated using a structure estimation method. This corresponds to half-lives of 6.3 years at pH 7 and 230.2 days at pH 8.
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.
