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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Irrelevant
Key value for chemical safety assessment
Additional information
Data on phototransformation in soil are not available for the submission item. As this endpoint is not a standard information requirement in REACH and there is no indication from the Chemical Safety Assessment on the need to investigate further the fate and behaviour of the substance (Annex X, column 1, section 9.3.4. requirement), no testing is deemed necessary.
Due to the spectral properties of the submission item, i.e. absorption at 210 nm within the spectral range of natural daylight (ca. 200 to 2500 nm), direct photodegradation could be a potential degradation pathway, but the light transmission in soils is low and can only play a role in top layers of soils, which may represent 10 % or less of contaminated materials shifted to soils. Taking additionally the ready biodegradability into account, biotic degradation is expected overcompensating direct photolysis in soils by far. In conclusion the photolytic stability of the submission item seems irrelevant for the assessment of the fate in environmental soils.
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.
