Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The test substance had a maximum biodegradation of 10% in a modified Sturm test but as these the degradation occured during the last three days , adaptation seems to be required. It is forseen that with a prolongation of the test, more degradation is to be expected. The correponding monoconstituent substance was also found to be not readily biodegradable but up to 48% was degraded in the Modified Sturm test. Due to low solubility of the test substance no hydrolysis study could be performed.
The estimation study of the partition coefficient performed on the monoconstituent substance and used as read-across showed that the LogPow is 2.12 and therefore the substance is not considered to be bioaccumulative.
Estimation of the Adsorption Coefficient on soil for the monoconstituent substance used as read-across showed that the substance will not retained in soil to a significant extent.
In accordance with column 2 of REACh (Regulation (EC) No 1907/2006) Annex IX, the simulation testing on ultimate degradation in surface water, soil simulation testing, and sediment simulation testing (required in section 9.2.1.2, 9.2.1.3, and 9.2.1.4) do not need to be conducted based on the findings of the Chemical Safety Assessment; the substance does not fulfil classification criteria according to the applicable regulations and does not fulfil the criteria for vPvB or PBT.
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.
