Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Key value for chemical safety assessment
Additional information
In accordance with Regulation (EC) No 1907/2006, Annex IX, Section 9.2 and 9.2.1.2, Column 2, the simulation test on ultimate degradation in surface water does not need to be conducted as the chemical safety assessment according to Annex I indicates that there is no need to investigate further the degradation of the substance and its degradation products. The test item and the hydrolytic products were assessed. The test item is poorly biodegradable and hydrolyses slowly (pH7, 25°C diester 51 days and monoester 68 days) with increasing pH value, the hydrolysation process is faster (pH9, 25 °C diester 4 days; monoester 3 days). Via several further hydrolysis steps finally sebacic acid (111-20-6), which is readily biodegradable and 1,2,2,6,6-pentamethylpiperidin-4-ol (2403-89-6) are formed. The latter is inherently biodegradable and has a BCF of 2.68 L/kg ww.
Moreover, the risk characterization ratios (RCRs) of the chemical safety assessment are below 1, demonstrating the safe use of the substance throughout its lifecycle. Therefore, no simulation studies in soil are provided.
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.
