Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 substance is not readily biodegradable in OECD 301F test. There is no release to the aquatic compartment due to the handling of the substance in closed systems during formulation and the applications described in chapter 3.5 of IUCLID. Therefore, no further testing is proposed to investigate the degradation of the test substance.
The substance is considered to be hydrolytically stable at pH 4 and 7. Hydrolysis of the ester-bond was observed at pH 9.0. It is recognised that the nature of the test item is a UVCB, with many different chemical structures present in the substance, so it would be scientifically impracticable to make a detailed analytical evaluation of the exact chemical hydrolytic products. Hence Tier 2 studies cannot be performed.
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.
